Description

Breast pump and method for heating breast receiving means of a breast pump and method for sucking milk

Technical Field

The present invention relates to a breast pump, and more particularly to a breast pump and a method of heating a breast receiving means of a breast pump and a method of sucking milk.

Background

Breast pumps are well known devices for assisting a user in draining breast milk from the breast, by means of which the breast can be emptied, the more milk in the breast is drained and the more milk is subsequently secreted, and thus the breast pump helps to promote lactation, wherein the breast pump includes both manual and electric breast pumps. In general (but not in all cases), when the infant is unable to directly suck breast milk or when the user needs to temporarily stop sucking, for example, when the mother and infant are separated, the infant is unable to directly suck breast milk, and the accumulated breast milk needs to be discharged from the breast by using a breast pump for storage or disposal. In addition, when a newborn is born, a user can quickly open milk with the help of the breast pump so as to make the first mouth milk eaten by the newborn be breast milk, which is particularly important for the growth and development of the newborn. When a user uses the breast pump, the user needs to clamp a part of the breast pump at the position of the breast, and the breast pump can discharge breast milk from the breast after the breast pump is operated to generate negative pressure in the breast pump. There are a number of drawbacks to the prior art breast pumps.

First, a conventional electric breast pump intermittently generates negative pressure inside the breast pump to suck milk by switching a suction pump (e.g., a piston suction pump) between an operating state and a non-operating state. The internal and external air pressures of the existing breast pump are the same when the suction pump is in a non-working state, so that a user needs to hold or hold the breast pump all the time by using the hand when using the breast pump, and the user easily feels tired when keeping the same tension posture for a long time because the time for using the breast pump is ten minutes or longer, and particularly, the user who just gives birth obviously feels no heart when using the breast pump.

Secondly, the breast cup of the breast pump is usually plastic products or silica gel products, when the breast pump is in a non-use state, the breast cup of the breast pump is exposed to the external environment, so that the temperature of the breast cup of the breast pump is similar to the temperature of the surrounding environment, especially in cold seasons in winter, the surface temperature of the breast cup of the breast pump can be very low, and a user cannot directly use the breast pump to suck milk, otherwise, the breast tissue of the breast is badly stimulated, and the secretion of prolactin and oxytocin is restrained, so that the lactation yield is reduced, and the body of the user is injured. Therefore, the user may want to raise the temperature of the cup of the breast pump before using the breast pump, and it is now the practice to soak or cook the cup in hot water to raise the temperature of the cup, but this is not only troublesome, but also the temperature of the cup is difficult to maintain, and when the breast pump is used for more than a certain period of time, the temperature of the cup is continuously and rapidly lowered, especially in a colder season in winter, the temperature of the cup is lowered more rapidly. That is, this current practice does not maintain the breast cup of the breast pump within a reasonable temperature range.

In addition, the user needs to relax the skin and tissue of the breast around the breast before using the breast pump to expel breast milk from the breast, especially in cold seasons, and further needs to use a hot towel to compress the breast, which has many problems, on one hand, the hot towel needs to be used for compressing the breast to soak the towel with hot water, so that the process is very troublesome, and after the hot towel cools down, the puerpera is easy to catch cold, on the other hand, the hot towel has a relatively high moisture content, clothes or bedclothes are relatively easy to wet during the compressing process, and more moisture remains on the surface of the breast skin after the compressing process is completed, so that after the compressing process is completed by using the hot towel, the breast skin is required to be wiped dry by using the dry towel, and bacteria can pollute the breast skin of the breast, and during the sucking process by using the breast pump, the bacteria can enter the sucked breast milk to cause further pollution, so that the safety of the breast milk is reduced.

Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the invention. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

It will be appreciated by those skilled in the art that in the present disclosure, the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc. refer to an orientation or positional relationship based on that shown in the drawings, which is merely for convenience of description and to simplify the description, and do not indicate or imply that the apparatus or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore the above terms should not be construed as limiting the present invention.

It will be understood that the terms "a" and "an" should be interpreted as referring to "at least one" or "one or more," i.e., in one embodiment, the number of elements may be one, while in another embodiment, the number of elements may be plural, and the term "a" should not be interpreted as limiting the number.

Referring to fig. 1A to 5B of the drawings, a breast pump according to a preferred embodiment of the present invention is set forth in the following description, wherein the breast pump comprises a breast pump body 10 and at least one breast receiving means 20, wherein each of the breast receiving means 20 is connected to the breast pump body 10, respectively. Each of the breast accommodating apparatuses 20 has an accommodating space 21 for accommodating a breast 100, wherein the breast pump body 10 is capable of forming a negative pressure environment in the accommodating space 21 of each of the breast accommodating apparatuses 20 to discharge breast milk from the breast 100.

It will be appreciated by those skilled in the art that the breast pump body 10 may be manually operated to create a negative pressure environment in the receiving space 21 of each of the breast receiving means 20 to expel breast milk from the breast 100. In addition, the breast pump body 10 may be automatically operated (e.g., supplied with power) to form a negative pressure environment in the accommodating space 21 of each of the breast accommodating apparatuses 20, so as to discharge breast milk from the breast 100.

Preferably, when the breasts 100 are received in the receiving spaces 21 of each of the breast receiving means 20, the breast pump body 10 is capable of forming an adsorption negative pressure in the receiving spaces 21 of each of the breast receiving means 20 to discharge breast milk from the breasts 100, and forming a sustain negative pressure in the receiving spaces 21 of each of the breast receiving means 20 to maintain the breast receiving means 20 in a position of the breasts 100, wherein the value of the adsorption negative pressure is greater than the value of the sustain negative pressure, and the adsorption negative pressure and the sustain negative pressure are alternately formed. It is understood that the value of the suction negative pressure and the value of the maintenance negative pressure are both greater than 0.

In the breast pump of the present invention, the manner in which the breast pump body 10 forms the negative pressure in the accommodating space 21 of each of the breast accommodating apparatuses 20 enables each of the breast accommodating apparatuses 20 to be held at the position of the breast 100 without being held or gripped by hand, so as to avoid the occurrence of an adverse phenomenon in which each of the breast accommodating apparatuses 20 is detached from the position of the breast 100, thereby facilitating the sucking process.

It should be noted that, the manner in which the breast pump body 10 alternately forms the suction negative pressure and the maintenance negative pressure formed in the accommodating space 21 of each of the breast accommodating spaces 20 enables each of the breast accommodating apparatuses 20 not to be maintained at the position of the breast 100 with the maintenance of an external force, so as to facilitate the suction of milk, which is unexpected in the related art breast pumps, and is particularly important for improving the convenience and comfort of the suction of milk.

In addition, the breast pump body 10 allows the breast 100 to be massaged during the sucking process by alternately forming the suction negative pressure and the maintenance negative pressure in the accommodating space 21 of each of the breast accommodating apparatuses 20, to relax the breast skin and breast tissue of the breast 100, and to facilitate the health of the breast 100 of the user. In addition, the breast pump body 10 can gradually adapt the breast skin of the breast 100 to the negative pressure environment in the accommodating space 21 in such a manner that the suction negative pressure and the maintenance negative pressure formed in the accommodating space 21 of each of the breast accommodating apparatuses 20 are alternately formed, so as to avoid a large pressure on the breast skin and the breast tissue of the breast 100 during the sucking by the breast pump of the present invention.

In a preferred example of the breast pump of the present invention, the breast receiving means 20 is embodied in a horn shape or a funnel shape, such that the breast receiving means 20 forms the receiving space 21 for receiving the breast 100. Of course, those skilled in the art will appreciate that the breast receiving device 20 may be embodied in other possible shapes, and the breast pump of the present invention is not limited in this respect.

More preferably, the shape of the receiving space 21 of the breast receiving means 20 is matched with the shape of the breast 100 so that the breast receiving means 20 and the breast 100 are better fitted together, thereby making the negative pressure always present in the receiving space 21 of the breast receiving means 20 and making the sucking process more comfortable.

Each of the breast receiving means 20 is detachably connected to the breast pump body 10 in such a way that, on the one hand, after the breast pump has been used, the user can clean and disinfect the breast receiving means 20 and the breast pump body 10, respectively, and, on the other hand, the breast pump allows the user to select and replace the breast receiving means 20 with receiving spaces 21 of different sizes as desired.

Further, the breast pump comprises a maintaining means 30, wherein each of the breast accommodating apparatuses 20 is connected to the maintaining means 30, respectively, to raise the temperature of each of the breast accommodating apparatuses 20 and maintain the temperature of each of the breast accommodating apparatuses 20 in a proper temperature range by means of the maintaining means 30.

It is worth mentioning that the suitable temperature range referred to in the breast pump of the present invention means that the temperature of the breast receiving means 20 corresponds to the temperature of the breast skin of the breast 100, i.e. the temperature of the breast receiving means 20 is not excessively higher than the temperature of the breast skin of the breast 100 nor excessively lower than the temperature of the breast skin of the breast 100.

The maintenance device 30 is capable of raising the temperature of each of the breast receiving devices 20 to a suitable temperature range before each of the breast receiving devices 20 is not engaged with the breast skin of the breast 100, so that the breast receiving devices 20 do not cause undesirable irritation to the breast skin and breast tissue of the breast 100 when each of the breast receiving devices 20 is engaged with the breast skin of the breast 100. In other words, the breast receiving means 20 can be preheated.

In addition, the breast accommodating apparatus 20 can raise the temperature of the breast skin of the breast 100 to play a role in relaxing and massaging the breast skin and breast tissue of the breast 100, and the breast accommodating apparatus 20 can stimulate the brain to produce oxytocin and prolactin, so that the breast pump can not only feel comfortable to a user during the breast pumping process using the breast pump of the present invention, but also effectively improve the breast pumping effect and ensure the breast milk quality.

The number of breast receiving means 20 is not limited in the breast pump of the present invention, for example in the example of the breast pump shown in fig. 1A, the number of breast receiving means 20 may be one; in the example of the breast pump shown in fig. 1B, the number of breast receiving means 20 may be two; in the example of the breast pump shown in fig. 1C, the number of breast receiving devices 20 may also be more than two, for example the holding device 30 may be preset in a hospital delivery room, the user may attach the breast receiving device 20 to the holding device 30 during use of the breast pump, to raise the temperature of the breast receiving device 20 by means of the holding device 30 and to maintain the temperature of the breast receiving device 20 in a suitable temperature range, and the breast receiving device 20 may be detached from the holding device 30 after the user has used the breast pump.

It is worth mentioning that in the following description of the present invention, features and advantages of the breast pump of the present invention will be further elucidated, taking as an example the breast pump formed by the breast receiving means 20 being embodied as one and the breast pump body 10, the breast receiving means 20 and the breast pump body 10 being assembled together.

Specifically, referring to fig. 1D and 1E, the breast receiving device 20 is detachably mounted to the breast pump body 10, wherein the breast receiving device 20 is coupled to the breast pump body 10 after the breast receiving device 20 is mounted to the breast pump body 10.

The maintaining means 30 is detachably mounted to the breast pump body 10, and the maintaining means 30 is detachably connected to the breast accommodating apparatus 20, wherein the maintaining means 30 is capable of raising the temperature of the breast accommodating apparatus 20 and maintaining the temperature of the breast accommodating apparatus 20 in a proper temperature range after the maintaining means 30 is connected to the breast accommodating apparatus 20.

The breast receiving device 20 has a soaking space 22, at least one first exchanging channel 23 and at least one second exchanging channel 24, wherein each of the first exchanging channel 23 and each of the second exchanging channels 24 are respectively communicated with the soaking space 22. The maintenance device 30 has a heat generating space 31, wherein each of the first exchanging channels 23 of the breast accommodating apparatus 20 is respectively communicated with the heat generating space 31 of the maintenance device 30.

In one example of the breast pump of the present invention, the maintaining means 30 increases the temperature within the heat generating space 31 to increase the air pressure within the heat generating space 31 of the maintaining means 30, such that a higher temperature fluid (e.g., without limitation, a liquid, a gas-liquid mixture) within the heat generating space 31 of the maintaining means 30 enters the soaking space 22 through each of the first exchange channels 23 of the breast accommodating means 20 to cause a lower temperature fluid within the soaking space 22 to be expelled from the soaking space 22 through each of the second exchange channels 24, such that a higher temperature gas increases the temperature of the breast accommodating means 20.

The fluid having a relatively high temperature in the heat generating space 31 of the maintaining means 30 continuously enters the soaking space 22 through each of the first exchanging channels 23 of the breast accommodating means 20, and the fluid of the soaking space 22 is continuously discharged out of the soaking space 22 through each of the second exchanging channels 24, so that the temperature of the breast accommodating means 20 is maintained in a proper temperature range.

Preferably, each of the second exchanging channels 24 of the breast accommodating apparatus 20 is respectively communicated with the heat generating space 31 of the maintaining apparatus 30, so that the fluid in the soaking space 22 of the breast accommodating apparatus 20 can be discharged into the heat generating space 31 of the maintaining apparatus 30 through each of the second exchanging channels 24 to achieve recovery and reuse of the gas. That is, the heat generating space 31 of the maintaining means 30, each of the first exchanging channel 23, the soaking space 22 and each of the second exchanging channels 24 of the breast accommodating apparatus 20 form a fluid circulation circuit to perform heat exchange.

For example, in another example of the breast pump of the present invention, the maintaining means 30 may raise the temperature of the breast accommodating apparatus 20 and maintain the temperature of the breast accommodating apparatus 20 in a suitable temperature range by steaming water or other liquid located in the heat generating space 31.

Specifically, the maintaining means 30 causes the water or other liquid located in the heat generating space 31 to form the vapor, wherein the vapor enters the soaking space 22 through each of the first exchanging channels 23 of the breast accommodating means 20, the temperature of the breast accommodating means 20 is raised by the vapor being converted from a gas state to a liquid state in the soaking space 22 to release heat, and the water or other liquid converted to a liquid state is recovered from each of the second exchanging channels 24 of the breast accommodating means 20 to the heat generating space 31 of the maintaining means 30 to achieve recovery and reuse of the water or other liquid.

That is, the heat generating space 31 of the maintaining means 30, each of the first exchanging channel 23, the soaking space 22 and each of the second exchanging channels 24 of the breast accommodating apparatus 20 form a liquid circulation loop to perform heat exchange.

The maintaining means 30 maintains the temperature of the breast accommodating apparatus 20 in a proper temperature range by continuously forming the steam from water or other liquid located in the heat generating space 31 and continuously introducing the steam into the soaking space 22 of the breast accommodating apparatus 20.

Further, the maintaining means 30 includes a container 32 and a heating element 33, wherein the container 32 has the heat generating space 31 for containing water or other liquid, the heating element 33 is provided to the container 32, and the heating element 33 is supplied with energy (e.g., supplied with power) for heating the water or other liquid contained in the heat generating space 31 of the container 32 so that the water or other liquid enters the soaking space 22 through each of the first exchanging channels 23 of the breast accommodating apparatus 20 after forming the vapor, thereby raising the temperature of the breast accommodating apparatus 20 and maintaining the temperature of the breast accommodating apparatus 20 in a proper temperature range.

The breast accommodating apparatus 20 includes an inner side 25 and an outer side 26, wherein the inner side 25 and the outer side 26 of the breast accommodating apparatus 20 are disposed to overlap each other to form the soaking space 22 and each of the first exchanging channels 23 and each of the second exchanging channels 24 respectively communicating with the soaking space 22 between the inner side 25 and the outer side 26. The inner side 25 of the breast receiving means 20 forms the receiving space 21 and a milk sucking channel 27 communicating with the receiving space 21.

It is worth mentioning that in a preferred example of the breast pump of the present invention, the inner side 25 and the outer side 26 of the breast receiving means 20 may be integrally formed to form the soaking space 22 and each of the first exchange passages 23 and each of the second exchange passages 24 respectively communicating with the soaking space 22 between the inner side 25 and the outer side 26.

In another preferred example of the breast pump of the present invention, the inner side 25 and the outer side 26 of the breast receiving means 20 may also be manufactured separately, and then the soaking space 22 and each of the first exchange passages 23 and each of the second exchange passages 24 respectively communicating with the soaking space 22 are formed between the inner side 25 and the outer side 26 by assembling the inner side 25 and the outer side 26 to overlap each other.

The first and second exchanging passages 23 and 24 may be formed at the same time in the inner side portion 25 or the outer side portion 26, so that the first and second exchanging passages 23 and 24 communicate with the soaking space 22 formed between the inner side portion 25 and the outer side portion 26, respectively. Or one of the first and second exchanging channels 23 and 24 is formed at the inner side 25 and the other is formed at the outer side 26, so that the first and second exchanging channels 23 and 24 communicate with the soaking space 22 formed between the inner side 25 and the outer side 26, respectively.

Accordingly, it will be appreciated by those skilled in the art that the manner in which the breast receiving device 20 is formed is not limited in the breast pump of the present invention.

The maintaining device 30 further comprises a temperature maintaining element 34, wherein the temperature maintaining element 34 is disposed on the breast accommodating apparatus 20, or the temperature maintaining element 34 is formed on the breast accommodating apparatus 20, so as to maintain the temperature of the breast accommodating apparatus 20 in a proper temperature range by the temperature maintaining element 34. Preferably, the temperature maintaining element 34 is made of a material that is well insulated, for example, the temperature maintaining element 34 may be, but is not limited to, insulating cotton.

In one example of the breast pump shown with reference to fig. 2 to 4, the temperature maintaining element 34 may be a separate component which is, after formation, arranged overlapping the outer side 26 of the breast receiving means 20 for preventing the temperature within the soaking space 22 of the breast receiving means 20 from being exchanged through the outer side 26 of the breast receiving means 20 and the external environment of the breast receiving means 20, such that the temperature of the breast receiving means 20 is maintained in a suitable temperature range.

It should be noted that the temperature maintaining element 34 may be overlapped on the inner surface of the outer side 26 of the breast accommodating apparatus 20 such that the temperature maintaining element 34 is held in the soaking space 22. The temperature maintaining element 34 may be provided to overlap with the outer surface of the outer side 26 of the breast accommodating apparatus 20.

In other examples of the breast pump of the invention, the temperature maintaining element 34 may also be integrally formed with the outer side 26 of the breast receiving means 20, e.g. the temperature maintaining element 34 may be integrally formed with the inner and/or outer surface of the outer side 26 of the breast receiving means 20. Specifically, a heat insulating material may be applied to the inner and/or outer surfaces of the outer side 26 of the breast accommodating apparatus 20 such that the heat insulating material forms the temperature maintaining element 34 overlapping the inner and/or outer surfaces of the outer side 26, thereby preventing the temperature within the soaking space 22 of the breast accommodating apparatus 20 from being exchanged with the external environment of the breast accommodating apparatus 20 by the temperature maintaining element 34, and thus maintaining the temperature of the breast accommodating apparatus 20 in a proper temperature range.

In other examples of the breast pump of the invention, the temperature maintaining element 34 of the maintaining means 30 and the outer side 26 of the breast receiving means 20 are of a unitary structure. For example, the outer side 26 of the breast receiving device 20 may have a thermal insulating capability to prevent heat within the soak space 22 of the breast receiving device 20 from being exchanged with the external environment through the outer side 26 of the breast receiving device 20, such that the temperature of the breast receiving device 20 is maintained in a suitable temperature range.

The breast pump body 10 comprises a milk container 11 and a negative pressure generating assembly 12, wherein the milk container 11 is provided with a milk containing space 111, a milk inlet 112 and a negative pressure generating channel 113, wherein the milk inlet 112 and the negative pressure generating channel 113 are respectively communicated with the milk containing space 111, the negative pressure generating assembly 12 is arranged on the milk container 11, and the negative pressure generating assembly 12 is communicated with the negative pressure generating channel 113 of the milk container 11. The breast receiving device 20 is mounted to the milk container 11 of the breast pump body 10, and the milk suction channel 27 of the breast receiving device 20 communicates with the milk inlet 112 of the milk container 11. The negative pressure generating assembly 12, when supplied with energy (e.g., supplied with power), is capable of creating a negative pressure environment within the receiving space 21 of the breast receiving device 20 for a milking operation.

It should be noted that the control manner of the negative pressure generating assembly 12 is not limited in the breast pump of the present invention, for example, the negative pressure generating assembly 12 may include a vacuum generator and a solenoid valve, wherein the vacuum generator and the solenoid valve can be mutually matched so that the state of the negative pressure generating assembly 12 is changed, thereby enabling the negative pressure generating assembly 12 to alternately generate the suction negative pressure and the maintenance negative pressure in the accommodating space 21 of the breast accommodating apparatus 20.

The breast pump further comprises a power supply 40, wherein the negative pressure generating assembly 12 is electrically connected to the power supply 40 for supplying power to the negative pressure generating assembly 12 via the power supply 40, thereby operating the negative pressure generating assembly 12 to further create a negative pressure environment within the receiving space 21 of the breast receiving device 20.

It should be noted that the type of the power supply device 40 is not limited, as long as it can supply power to the negative pressure generating assembly 12. For example, the power supply device 40 may be implemented as a dry battery, a lithium battery, or the like, and the power supply device 40 may be implemented as a disposable battery, a rechargeable battery, or the like. Preferably, in this specific example of the breast pump of the invention, the power supply means 40 is implemented as a rechargeable battery, allowing external electrical energy to be supplemented to the power supply means 40, thereby reducing the costs of use of the breast pump.

Further, the maintaining device 30 may also be electrically connected to the power supply device 40 to supply power to the maintaining device 30 via the power supply device 40, so that the temperature of the gas or the temperature of the water or other liquid in the heat generating space 31 of the maintaining device 30 can be increased. Preferably, the heating element 33 of the maintaining means 30 is connected to the power supply means 40 to generate heat from the heating element 33 by the power supplied from the power supply means 40, thereby converting water or other liquid into the steam by heating the water or other liquid contained in the heat generating space 31.

In addition, the breast pump may further comprise a housing 50, wherein the power supply means 40, the negative pressure generating assembly 12 of the breast pump body 10 and the maintaining means 30 may be provided to the housing 50 to be integrated. When the housing 50 is mounted to the milk container 11 of the breast pump body 10, the negative pressure generating assembly 12 communicates with the negative pressure generating passage 113 of the milk container 11.

However, it will be appreciated by those skilled in the art that in other examples of the breast pump of the present invention, it is also possible to integrate only the power supply 40 and the negative pressure generating assembly 12 of the breast pump body 10 in the housing 50.

Referring to fig. 2, the breast 100 received in the receiving space 21 of the breast receiving device 20 is fitted to the inner side 25 of the breast receiving device 20 such that the breast receiving device 20 surrounds the circumference of the breast 100 when the user uses the breast pump. When the maintenance device 30 increases the temperature of the breast accommodating apparatus 20 after being supplied with power, the breast accommodating apparatus 20 increases the temperature of the breast skin and breast tissue of the breast 100 in synchronization by being in direct contact with the breast skin of the breast 100, thereby relaxing the breast skin and breast tissue of the breast 100.

Referring to fig. 3 and 4, when the user uses the breast pump, a heat sustaining space 200 is generated between the breast 100 received in the receiving space 21 of the breast receiving means 20 and the inner side 25 of the breast receiving means 20, wherein the heat sustaining space 200 surrounds the circumference of the breast 100. When the maintaining means 30 increases the temperature of the breast accommodating means 20 after being supplied with power, the temperature of the breast accommodating means 20 is exchanged with the temperature of the heat maintaining space 200 to further increase the temperature of the heat maintaining space 200, thereby increasing the temperature of the breast skin of the breast 100 in synchronization, thereby relaxing the breast skin and breast tissue of the breast 100.

It is worth mentioning that although the breast pump is capable of creating the heat sustaining space 200 between the breast 100 and the inner side 25 of the breast receiving means 20, the lower side of the breast 100 may contact or fit against the inner side 25 of the breast receiving means 20 due to the weight of the breast 100 itself, whereas the heat sustaining space 200 is formed only between the upper side and/or both sides of the breast 100 and the inner side 25 of the breast receiving means 20.

FIGS. 5A and 5B illustrate the use of the breast pump by a user in a relatively low temperature environment.

Power is supplied to the maintenance device 30 to raise the temperature of the breast accommodating apparatus 20 by means of the maintenance device 30. It will be appreciated that the power supply 40 may be used to supply power to the maintenance device 30. When the temperature of the breast accommodating apparatus 20 is equal to the breast skin temperature of the breast 100, the breast accommodating apparatus 20 is placed at a position of the breast 100 such that the breast 100 is accommodated in the accommodating space 21 of the breast accommodating apparatus 20. Preferably, the heat maintaining space 200 is generated between the inner side 25 of the breast accommodating apparatus 20 and the breast 100 after the breast 100 is accommodated in the accommodating space 21 of the breast accommodating apparatus 20.

It is worth mentioning that the maintaining means 30 is continuously supplied with power so that the temperature of the breast accommodating apparatus 20 is maintained in a suitable temperature range. It will be appreciated that the temperature maintaining element 34 provided to the breast receiving device 20 can prevent the temperature of the breast receiving device 20 from being exchanged with the external environment, so that the temperature maintaining element 34 can maintain the temperature of the breast receiving device 20 in a proper temperature range and reduce the consumption of electric energy by the maintaining device 30, thereby improving the cruising ability of the breast pump and reducing the use cost of the breast pump.

Power is supplied to the negative pressure generating assembly 12 of the breast pump body 10 such that the negative pressure generating assembly 12 creates a negative pressure environment within the receiving space 21 of the breast receiving means 20. It will be appreciated that the power supply 40 may be used to supply power to the negative pressure generating assembly 12. Referring to fig. 5A, the negative pressure generating assembly 12 can form the holding negative pressure in the receiving space 21 of the breast receiving means 20 so that the breast receiving means 20 is held at the position of the breast 100, so that the breast receiving means 20 is not detached from the breast 100 even when the user does not hold or grip the breast pump by hand, to improve reliability of the breast pump when in use. Referring to fig. 5B, the negative pressure generating assembly 12 is capable of causing the accommodating space 21 of the breast accommodating apparatus 20 to form the suction negative pressure to discharge breast milk from the breast 100 to the outside. It will be appreciated that the negative pressure generating assembly 12 alternately forms the suction negative pressure and the maintenance negative pressure in the accommodating space 21 of the breast accommodating apparatus 20 to enhance the sucking effect.

Referring to fig. 6A to 10 of the drawings, a breast pump according to another preferred embodiment of the present invention will be described in the following description, wherein the breast pump comprises a breast pump body 10A and at least one breast receiving means 20A, wherein each of the breast receiving means 20A is connected to the breast pump body 10A, respectively. Each of the breast accommodating apparatuses 20A has an accommodating space 21A for accommodating a breast 100A, wherein the breast pump body 10A is capable of creating a negative pressure environment in the accommodating space 21A of each of the breast accommodating apparatuses 20A to discharge breast milk from the breast 100A.

It should be noted that the number of breast receiving devices 20A is not limited in the breast pump of the present invention, and in the following description of the present invention, the features and advantages of the breast pump of the present invention will be described with reference to the breast receiving device 20A being implemented as one example, and thus, it will be understood by those skilled in the art that the breast pump shown in fig. 6A to 10 and the breast pump shown in the following description should not be construed as limiting the content and scope of the breast pump of the present invention.

Specifically, when the breasts 100A are accommodated in the accommodating spaces 21A of the breast accommodating apparatuses 20A, the breast pump body 10A is capable of forming an adsorption negative pressure in the accommodating space 21A of each of the breast accommodating apparatuses 20A to discharge breast milk from the breasts 100A, and forming a maintenance negative pressure in the accommodating spaces 21A of the breast accommodating apparatuses 20A to cause the breast accommodating apparatuses 20A to be held in the positions of the breasts 100A, wherein the value of the adsorption negative pressure is larger than that of the maintenance negative pressure, and the adsorption negative pressure and the maintenance negative pressure are alternately formed. It is understood that the value of the suction negative pressure and the value of the maintenance negative pressure are both greater than 0.

In other words, the user can form a negative pressure environment in the accommodating space 21A of the breast accommodating apparatus 20A by the breast pump body 10A during the whole process of using the breast pump, in such a way that the breast accommodating apparatus 20A can be maintained at the position of the breast 100A without being held or gripped by hand, without being detached from the position of the breast 100A, thereby facilitating the sucking process.

In the breast pump according to the second preferred embodiment of the present invention, the breast receiving means 20A of the breast pump may be implemented as a horn or a funnel, like the breast pump according to the first preferred embodiment of the present invention, so that the breast receiving means 20A forms the receiving space 21A for receiving the breast 100A. Preferably, the shape of the receiving space 21A of the breast receiving means 20A is matched with the shape of the breast 100A so that the breast receiving means 20A and the breast 100A are better fitted together.

Preferably, the breast receiving means 20A is detachably connected to the breast pump body 10A in such a way that, on the one hand, a user can clean and disinfect the breast receiving means 20A and the breast pump body 10A, respectively, after using the breast pump, and, on the other hand, the user can replace the breast receiving means 20A with the receiving space 21A of a different size as desired.

With continued reference to fig. 6A-10, the breast pump further comprises a maintaining means 30A, wherein the breast receiving means 20A is connected to the maintaining means 30A for raising the temperature of the breast receiving means 20A and maintaining the temperature of the breast receiving means 20A in a suitable temperature range by means of the maintaining means 30A.

It is worth mentioning that the suitable temperature range referred to in the breast pump of the present invention means that the temperature of the breast receiving means 20A corresponds to the temperature of the breast skin of the breast 100A, i.e. the temperature of the breast receiving means 20A is not excessively high compared to the temperature of the breast skin of the breast 100A, nor excessively low compared to the temperature of the breast skin of the breast 100A, such that the temperature of the breast receiving means 20A effectively increases the comfort and affinity of the breast pump when the user uses the breast pump.

The maintenance device 30A is capable of raising the temperature of the breast receiving device 20A to a suitable temperature range before the breast receiving device 20A is not engaged with the breast skin of the breast 100A, such that the breast skin and breast tissue of the breast 100A are not stimulated by the breast receiving device 20A when the breast receiving device 20A is operated to engage the breast skin of the breast 100A.

In further examples, the temperature of the breast receiving means 20A may be slightly higher than the temperature of the breast skin of the breast 100A, such that when the breast receiving means 20A is operated to fit against the breast skin of the breast 100A, the breast receiving means 20A can raise the temperature of the breast skin of the breast 100A to relax and massage the breast skin and breast tissue of the breast 100A, thereby not only making the user feel comfortable during use of the breast pump of the present invention, but also effectively improving the milk sucking effect and ensuring the quality of breast milk.

Referring to fig. 6A, the breast receiving device 20A is detachably mounted to the breast pump body 10A, wherein the breast receiving device 20A is coupled to the breast pump body 10A after the breast receiving device 20A is mounted to the breast pump body 10A.

The maintaining means 30A is detachably mounted to the breast pump body 10A, and the maintaining means 30A is detachably connected to the breast accommodating means 20A, wherein after the maintaining means 30A is connected to the breast accommodating means 20A, the maintaining means 30A is capable of raising the temperature of the breast accommodating means 20A and maintaining the temperature of the breast accommodating means 20A in a proper temperature range.

The breast accommodating apparatus 20A includes an inner side 25A, an outer side 26A, and a soaking member 28A, wherein the soaking member 28A is disposed between the inner side 25A and the outer side 26A overlapping each other, and the inner side 25A forms the accommodating space 21A and forms a milk sucking passage 27A communicating with the accommodating space 21A. Preferably, the soaking element 28A surrounds the accommodation space 21A, and when heat is supplied to the soaking element 28A, the soaking element 28A can uniformly radiate heat to the accommodation space 21A to raise the temperature inside the accommodation space 21A. Of course, the soaking element 28A can also uniformly radiate heat to the inner side 25A to raise the temperature of the inner side 25A.

In one example of the breast pump of the present invention, the inner side 25A, the outer side 26A and the soaking element 28A of the breast accommodating apparatus 20A are manufactured separately, and then the soaking element 28A is disposed between the inner side 25A and the outer side 26A overlapping each other, for example, the inner side 25A and the outer side 26A may be coupled together by being engaged with each other so that the soaking element 28A is held between the inner side 25A and the outer side 26A, or an edge of the inner side 25A and an edge of the outer side 26A are bonded together so that the soaking element 28A is held between the inner side 25A and the outer side 26A.

In another example of the breast pump of the present invention, the inner side 25A, the outer side 26A and the soaking element 28A of the breast accommodating apparatus 20A may be integrally formed, for example, the soaking element 28A is first placed in a molding space of a molding die, and then the molding material is put into the molding space to wrap the soaking element 28A, so that after the molding material is cured in the molding space, the molding material forms the inner side 25A and the outer side 26A on the inner side and the outer side of the soaking element 28A, respectively, i.e., the inner side 25A, the soaking element 28A and the outer side 26A may be integrally molded by an insert injection process. Of course, other molding processes may be used to integrally mold the soaking element 28A between the inner side 25A and the outer side 26A to form the breast accommodating apparatus 20A.

It will be appreciated by those skilled in the art that the manner in which the breast receiving device 20A is made as illustrated above is by way of example only and should not be taken as limiting the scope and content of the breast pump of the invention.

The maintenance device 30A comprises a heating element 35A, the soaking element 28A of the breast accommodating apparatus 20A being thermally conductively connected to the heating element 35A of the maintenance device 30A, wherein when the heating element 35A is supplied with energy (e.g. supplied with power), the heating element 35A is capable of converting the energy into heat, and the heat generated by the heating element 35A is conducted to the soaking element 28A of the breast accommodating apparatus 20A, thereby increasing the temperature of the breast accommodating apparatus 20A.

It will be appreciated that the temperature of the breast receiving device 20A is maintained within a suitable temperature range as the heat generating element 35A continuously generates and conducts heat to the soaking element 28A of the breast receiving device 20A.

The maintaining device 30A further comprises a temperature maintaining element 34A, wherein the temperature maintaining element 34A is disposed on the breast accommodating apparatus 20A to maintain the temperature of the breast accommodating apparatus 20A in a suitable temperature range by the temperature maintaining element 34A.

Referring to fig. 7A, in this example of the breast pump of the present invention, the temperature maintaining element 34A of the maintaining means 30A is a separate component, in a specific example of the breast pump, the temperature maintaining element 34A is overlapped with the soaking element 28A, the inner side 25A of the breast accommodating means 20A is overlapped with the soaking element 28A, the outer side 26A of the breast accommodating means 20A is overlapped with the temperature maintaining element 34A, and the inner side 25A and the outer side 26A of the breast accommodating means 20A are connected together such that the temperature maintaining element 34A and the soaking element 28A are held between the outer side 26A and the inner side 25A of the breast accommodating means 20A.

That is, the breast accommodating apparatus 20A is the outer side 26A, the temperature maintaining element 34A, the soaking element 28A, and the inner side 25A in this order from the outside to the inside, in such a manner that the temperature maintaining element 34A can prevent the soaking element 28A from radiating the heat to the outer side 26A of the breast accommodating apparatus 20A while only the soaking element 28A radiates the heat to the inner side 25A of the breast accommodating apparatus 20A, that is, the temperature maintaining element 34A may have good heat insulation, for example, the temperature maintaining element 34A may be implemented as, but not limited to, heat insulating cotton or other elements having a heat insulating function.

It will be appreciated by those skilled in the art that the temperature maintaining element 34A not only rapidly increases the temperature of the breast receiving device 20A, but also maintains the temperature of the breast receiving device 20A in a suitable temperature range when the heating element 35A provides a small amount of heat after the temperature of the breast receiving device 20A increases, thereby saving energy and improving the cruising ability of the breast pump.

In another specific example of the breast pump, the temperature maintaining element 34A and the soaking element 28A may be placed in the molding space of the molding die after being overlapped, so that the temperature maintaining element 34A and the soaking element 28A are wrapped with the molding material added to the molding space in the molding space, thereby forming the inner side 25A of the breast accommodating apparatus 20A on the soaking element 28A side and the outer side 26A of the breast accommodating apparatus 20A on the temperature maintaining element 34A side after the molding material is cured.

Referring to fig. 7B, in other examples of the breast pump of the present invention, the temperature maintaining element 34A may be integrally formed with the soaking element 28A of the breast receiving device 20A. Specifically, a heat insulating material may be applied to the side of the soaking element 28A facing the outer side 26A of the breast accommodating apparatus 20A such that the heat insulating material forms the temperature maintaining element 34A overlapping the soaking element 28A, thereby preventing the soaking element 28A from radiating the heat to the outer side 26A of the breast accommodating apparatus 20A by the temperature maintaining element 34A. That is, the temperature maintaining element 34A may be a heat insulating layer.

Referring to fig. 7C, in other examples of the breast pump of the present invention, the temperature maintaining element 34A may also be integrally formed with the outer side 26A of the breast receiving device 20A, such that the soaking element 28A is prevented from radiating this heat to the outer side 26A of the breast receiving device 20A by the temperature maintaining element 34A. For example, the temperature maintaining element 34A may be integrally formed on an inner surface and/or an outer surface of the outer side 26A of the breast receiving device 20A to prevent the soaking element 28A from radiating the heat to the outer side 26A of the breast receiving device 20A by the temperature maintaining element 34A.

The soaking element 28A of the breast receiving means 20A and the heating element 35A of the maintaining means 30A may be directly connected together so that after the heating element 35A of the maintaining means 30A is supplied with energy to generate the heat, the heat can be directly conducted to the soaking element 28A.

In addition, the maintaining device 30A may also include at least one heat conducting element 36A, wherein each heat conducting element 36A is connected to the heat generating element 35A. The soaking element 28A of the breast receiving device 20A can be connected to each of the heat conducting elements 36A to conduct heat generated by the heat generating element 28 to the soaking element 28A by means of each of the heat conducting elements 36A. Preferably, the intervals between the adjacent heat conducting elements 36A are equal so that the heat generated by the heat generating element 35A can be uniformly conducted to the soaking element 28A. In another example of the breast pump, each of the heat conducting elements 36A may also be connected to the soaking element 28A, so that each of the heat conducting elements 36A can be connected to the heating element 35A when the breast receiving means 20A and the maintaining means 30A are connected to each other.

It will be appreciated by those skilled in the art that the heat conducting element 36A may be made of a material having good thermal conductivity so that the heat generated by the heating element 35A can be quickly conducted to the soaking element 28A with reduced losses when the heat is conducted by the heat conducting element 36A, in such a way that the efficiency of the maintaining means 30A to raise the temperature of the breast accommodating apparatus 20A can be effectively improved.

The breast pump further comprises a power supply means 40A, wherein the heating element 35A of the maintaining means 30A is electrically connected to the power supply means 40A, such that when the power supply means 40A supplies power to the heating element 35A of the maintaining means 30A, the heating element 35A can generate the heat, and the heat generated by the heating element 35A can be conducted to the soaking element 28A directly or through each of the heat conducting elements 36A, to raise the temperature of the breast accommodating means 20A and maintain the temperature of the breast accommodating means 20A in a suitable temperature range.

It should be noted that the type of the power supply device 40A is not limited as long as it can supply power to the heating element 35A of the maintenance device 30A. For example, the power supply device 40A may be implemented as a dry battery, a lithium battery, or the like, and the power supply device 40A may be implemented as a disposable battery, a rechargeable battery, or the like. Preferably, in this specific example of the breast pump of the invention, the power supply means 40A is implemented as a rechargeable battery, allowing external electrical energy to be supplemented to the power supply means 40A, thereby reducing the costs of use of the breast pump.

It should be noted that the negative pressure generating assembly 12A of the breast pump body 10A can be controlled such that the receiving space 21A of the breast receiving means 20A alternately forms the suction negative pressure and the sustaining negative pressure, wherein the manner of control of the negative pressure generating assembly 12A is not limited in the breast pump of the present invention, for example, the negative pressure generating assembly 12A can be controlled by a solenoid valve.

Referring to fig. 8, when the user uses the breast pump, the breast 100A received in the receiving space 21A of the breast receiving means 20A is fitted to the inner side 25A of the breast receiving means 20A such that the breast receiving means 20A surrounds the periphery of the breast 100A. The heat generating element 35A of the maintaining means 30A is supplied with electric power to generate the heat, and the heat is conducted to the soaking element 28A directly or through each of the heat conducting elements 36A to raise the temperature of the breast accommodating means 20A, wherein the breast accommodating means 20A raises the temperature of the breast skin of the breast 100A in synchronization by being in direct contact with the breast skin of the breast 100A, thereby relaxing the breast skin and breast tissue of the breast 100A.

Referring to fig. 9 and 10, when the user uses the breast pump, a heat sustaining space 200A may be generated between the breast 100A received in the receiving space 21A of the breast receiving means 20A and the inner side 25A of the breast receiving means 20A, wherein the heat sustaining space 200A surrounds the periphery of the breast 100A.

It is worth mentioning that although the breast pump is capable of creating the heat sustaining space 200A between the breast 100A and the inner side 25A of the breast receiving means 20A, the lower side of the breast 100A may contact or fit the inner side 25A of the breast receiving means 20A due to the weight of the breast 100A itself, whereas the heat sustaining space 200A is formed only between the upper side and/or both sides of the breast 100A and the inner side 25A of the breast receiving means 20A.

It should be noted that the process of the breast pump shown in fig. 6A to 10 corresponds to the process of sucking milk of the breast pump shown in fig. 1A to 5B.

Referring to fig. 11 to 20 of the drawings, a breast pump according to still another preferred embodiment of the present invention will be described in the following description, wherein the breast pump comprises a breast pump body 10B and at least one breast receiving means 20B, wherein each of the breast receiving means 20B is connected to the breast pump body 10B, respectively. Each of the breast accommodating apparatuses 20B has an accommodating space 21B for accommodating a breast 100B, wherein the breast pump body 10B is capable of creating a negative pressure environment in the accommodating space 21B of each of the breast accommodating apparatuses 20B to discharge breast milk from the breast 100B.

It should be noted that the number of the breast accommodating apparatuses 20B is not limited in the breast pump of the present invention, and for example, the number of the breast accommodating apparatuses 20B may be one or two. Although the features and advantages of the breast pump of the present invention are illustrated in fig. 11-20 and described below by way of example only in which the breast pump includes one of the breast receiving devices 20B, it should be understood by those skilled in the art that the breast pump illustrated in fig. 11-20 and described below should not be construed as limiting the scope or content of the breast pump of the present invention.

It is also worth mentioning that the breast pump body 10B may be manually operated to create a negative pressure environment within the receiving space 21B of the breast receiving means 20B to expel breast milk from the breast 100B. In addition, the breast pump body 10B may be automatically operated (e.g., supplied with power to operate) to create a negative pressure environment in the accommodating space 21B of the breast accommodating apparatus 20B to discharge breast milk from the breast 100B.

Further, referring to fig. 11 to 13, the breast receiving device 20B is detachably mounted to the breast pump body 10B in such a manner that, on one hand, a user can detach the breast receiving device 20B and the breast pump body 10B to be washed and sterilized, respectively, after using the breast pump, and, on the other hand, the breast pump allows the user to select and replace the breast receiving device 20B having the receiving space 21B of a different size as needed. In addition, it will be appreciated by those skilled in the art that when either one of the breast receiving means 20B and the breast pump body 10B is damaged or not suitable for continued use, the user may replace only one of the damaged or unsuitable for continued use, thus reducing the cost of use of the breast pump.

Still further, the breast pump body 10B comprises a milk container 11B and a negative pressure generating assembly 12B, wherein the negative pressure generating assembly 12B is disposed on the milk container 11B, the breast receiving means 20B is detachably mounted on the milk container 11B of the breast pump body 10B, and the negative pressure generating assembly 12B is capable of forming a negative pressure environment in the receiving space 21B of the breast receiving means 20B. Preferably, the negative pressure generating assembly 12B is detachably mounted to the milk container 11B.

The milk container 11B has a milk containing space 111B, a milk sucking port 112B and a negative pressure generating channel 113B, wherein the milk sucking port 112B and the negative pressure generating channel 113B are respectively connected to the milk containing space 111B, and the negative pressure generating component 12B is connected to the milk containing space 111B through the negative pressure generating channel 113B after being mounted on the milk container 11B, so that the negative pressure generating component 12B can make the accommodating space 21B form a negative pressure environment through the milk container 11B.

The breast receiving means 20B has a milk sucking passage 27B, wherein the milk sucking passage 27B communicates with the receiving space 21B. After the breast accommodating apparatus 20B is mounted to the milk container 11B of the breast pump main body 10B, the milk suction passage 27B of the breast accommodating apparatus 20B communicates with the milk containing space 111B of the milk container 11B through the milk suction port 112B of the milk container 11B, so that the negative pressure generating assembly 12B communicates with the accommodating space 21B of the breast accommodating apparatus 20B, thereby forming a negative pressure environment in the accommodating space 21B by the negative pressure generating assembly 12B.

When sucking milk using the breast pump, the breast 100B is accommodated in the accommodating space 21B of the breast accommodating apparatus 20B, the negative pressure generating assembly 12B is supplied with energy (e.g., supplied with power) to cause the accommodating space 21B of the breast accommodating apparatus 20B to form an adsorption negative pressure to discharge breast milk from the breast 100B, and cause the accommodating space 21B of the breast accommodating apparatus 20B to form a maintenance negative pressure to cause the breast accommodating apparatus 20B to be held in the position of the breast 100B, wherein the value of the adsorption negative pressure is larger than that of the maintenance negative pressure, and the adsorption negative pressure and the maintenance negative pressure are alternately formed. It is understood that the value of the suction negative pressure and the value of the maintenance negative pressure are both greater than 0.

It should be noted that, in the breast pump of the present invention, the breast pump body 10B forms the negative pressure maintaining means in the accommodating space 21B of the breast accommodating apparatus 20B, and the breast accommodating apparatus 20B can be maintained at the position of the breast 100B without falling out of the position of the breast 100B even if it is not held or held by a hand during the whole process of using the breast pump by a user, thereby making the sucking process more convenient.

It is also worth mentioning that the manner in which the breast pump body 10B alternately forms the suction negative pressure and the maintenance negative pressure formed in the accommodating space 21B of the breast accommodating apparatus 20B enables the breast accommodating apparatus 20B to be maintained at the position of the breast 100B without the maintenance of external force, which is unexpected in the related art breast pump, is not only important for improving the convenience and comfort of the breast suction, but also enables the breast 100B to be massaged during the milk suction process to relax the breast skin and breast tissue of the breast 100B, thereby being beneficial to the health of the breast 100B of the user.

Preferably, the breast receiving means 20B may be implemented in a horn shape or a funnel shape such that the breast receiving means 20B forms the receiving space 21B. Of course, in other examples of the breast pump, the breast receiving device 20B may also be embodied in other possible shapes. It should be noted that the horn-shaped or funnel-shaped breast accommodating apparatus 20B is matched with the shape of the user's breast 100B so that no gap is generated between the breast accommodating apparatus 20B and the breast skin of the breast 100B after the breast 100B is accommodated in the accommodating space 21B of the breast accommodating apparatus 20B, and thus the negative pressure generating assembly 12B can form a negative pressure environment in the accommodating space 21B while providing a small vacuum suction force, by which the power requirement of the breast pump for the negative pressure generating assembly 12B is reduced to reduce the manufacturing cost of the breast pump and miniaturize and lighten the breast pump.

The breast pump further comprises a power supply 40B, wherein the negative pressure generating component 12B is electrically connected to the power supply 40B to supply power to the negative pressure generating component 12B via the power supply 40B, so that the receiving space 21B of the breast receiving device 20B alternately forms the suction negative pressure and the maintenance negative pressure via the negative pressure generating component 12B.

It will be appreciated by those skilled in the art that the manner of controlling the negative pressure generating assembly 12B is not limited in the breast pump of the present invention, for example, the negative pressure generating assembly 12 may comprise a vacuum generator and a solenoid valve, wherein the vacuum generator and the solenoid valve may be mutually matched such that the state of the negative pressure generating assembly 12 is changed, thereby enabling the negative pressure generating assembly 12 to alternately generate the suction negative pressure and the maintenance negative pressure in the receiving space 21 of the breast receiving device 20.

In addition, the type of the power supply device 40B is not limited as long as it can supply power to the negative pressure generating assembly 12B, and for example, the power supply device 40B can be implemented as a disposable battery or as a rechargeable battery. Preferably, the power supply 40B is implemented as a rechargeable lithium battery to allow external electrical energy to be supplemented to the power supply 40B, thereby reducing the use costs of the breast pump.

Further, the breast pump further comprises a housing 50B, wherein at least one of the power supply 40B and the negative pressure generating assembly 12B is integrated into the housing 50B. Preferably, the power supply device 40B and the negative pressure generating assembly 12B are both provided to the housing 50B.

The housing 50B is detachably mounted to the milk container 11B of the milk pump body 10B, wherein the negative pressure generating assembly 12B communicates with the negative pressure generating channel 113B of the milk container 11B when the housing 50B is mounted to the milk container 11B of the milk pump body 10B.

Accordingly, the second conductive member 62B is disposed on the breast receiving device 20B, and at least a portion of the second conductive member 62B is exposed on the surface of the breast receiving device 20B. When the housing 50B is mounted to the milk container 11B of the milk pump main body 10B, the first conductive member 61B and the second conductive member 62B contact each other to conduct the power supply 40B and the heat generating element 35B of the maintenance device 30B, in such a manner that the power supply 40B can supply power to the heat generating element 35B of the maintenance device 30B to cause the heat generating element 35B to generate heat.

That is, in this specific example of the breast pump of the present invention, the first conductive member 61B and the second conductive member 62B can be brought into contact with each other to turn on the power supply device 40B and the heating element 35B of the maintaining device 30B while the housing 50B is mounted to the milk container 11B of the breast pump main body 10B.

It will be appreciated by those skilled in the art that the embodiments of the first conductive member 61B and the second conductive member 62B shown in fig. 14-17 are merely examples to further illustrate the features and advantages of the breast pump of the present invention, and thus, the embodiments of the first conductive member 61B and the second conductive member 62B should not be construed as limiting the content and scope of the breast pump of the present invention.

Further, the breast receiving device 20B includes an inner portion 25B and an outer portion 26B, wherein the heating element 35B may be disposed between the inner portion 25B and the outer portion 26B overlapping each other such that the heating element 35B is disposed on the breast receiving device 20B.

In a specific example of the breast pump of the present invention, the inner side 25B and the outer side 26B of the breast receiving means 20B and the heating element 35B of the maintaining means 30B may be manufactured separately, and the inner side 25B and the outer side 26B may be held between the inner side 25B and the outer side 26B overlapping each other by snap-fit or the like. In another specific example of the breast pump of the present invention, the heating element 35B of the maintaining means 30B and the inner side 25B and the outer side 26B of the breast receiving means 20B may also be integrally formed.

In addition, the maintaining device 30B further includes a temperature maintaining element 34B, wherein the temperature maintaining element 34B is disposed on the breast accommodating apparatus 20B or the temperature maintaining element 34B may be formed on the breast accommodating apparatus 20B, so as to maintain the temperature of the breast accommodating apparatus 20B in a suitable temperature range by the temperature maintaining element 34B. Preferably, the temperature maintaining element 34B is made of a material that is well insulated, for example, the temperature maintaining element 34B may be heat insulating cotton.

The temperature maintaining element 34B may be a separate component which is overlapped on the outer side 26B of the temperature maintaining element 34B after being formed for preventing the temperature in the accommodating space 21B of the breast accommodating apparatus 20B from being exchanged through the outer side 26B of the breast accommodating apparatus 20B and the external environment of the breast accommodating apparatus 20B, thereby maintaining the temperature of the breast accommodating apparatus 20B in a proper temperature range.

Specifically, an insulating material may be applied to the inner and/or outer surfaces of the outer side 26B of the breast accommodating apparatus 20B to form the temperature maintaining member 34B overlapping the outer side 26B after the insulating material is cured, so that the temperature inside the accommodating space 21B of the breast accommodating apparatus 20B is prevented from exchanging with the external environment of the breast accommodating apparatus 20B by the temperature maintaining member 34B, thereby maintaining the temperature of the breast accommodating apparatus 20B in a proper temperature range.

In other examples of the breast pump of the invention, the temperature maintaining element 34B of the maintaining means 30B and the outer side 26B of the breast receiving means 20B are of unitary construction. For example, the outer side 26B of the breast receiving device 20B may have a thermal insulating capability to prevent heat within the receiving space 21B of the breast receiving device 20B from being exchanged with the external environment through the outer side 26B of the breast receiving device 20B, such that the temperature of the breast receiving device 20B is maintained in a suitable temperature range.

When the maintenance device 30B increases the temperature of the breast accommodating apparatus 20B after being supplied with power, the breast accommodating apparatus 20B increases the temperature of the breast skin of the breast 100B in synchronization by being in direct contact with the breast skin of the breast 100B, thereby relaxing the breast skin and breast tissue of the breast 100B.

Referring to fig. 19 and 20, when the user uses the breast pump, a heat sustaining space 200B is generated between the breast 100B received in the receiving space 21B of the breast receiving means 20B and the inner side 25B of the breast receiving means 20B, wherein the heat sustaining space 200B surrounds the periphery of the breast 100B. When the maintaining means 30B increases the temperature of the breast accommodating means 20B after being supplied with power, the temperature of the breast accommodating means 20B and the temperature of the heat maintaining space 200B are exchanged with each other to further increase the temperature of the heat maintaining space 200B, thereby increasing the temperature of the breast skin of the breast 100B in synchronization, and thus relaxing the breast skin and breast tissue of the breast 100B.

It is worth mentioning that although the breast pump is capable of creating the heat sustaining space 200B between the breast 100B and the inner side 25B of the breast receiving means 20B, the lower side of the breast 100B may contact or fit the inner side 25B of the breast receiving means 20B due to the weight of the breast 100B itself, while the heat sustaining space 200B is formed only between the upper side and/or both sides of the breast 100B and the inner side 25B of the breast receiving means 20B.

It is worth mentioning that the procedure of the breast pump shown in fig. 11 to 20 corresponds to the procedure of the breast pump shown in fig. 1A to 5B.

(a) Supplying power to a heating element 35B provided to the breast accommodating apparatus 20B such that the heating element 35B generates heat to heat the breast accommodating apparatus 20B; and (B) preventing the heat generated by the heat generating element 35B from radiating to the external environment of the breast accommodating apparatus 20B, so that the temperature of the breast accommodating apparatus 20B is maintained in a suitable temperature range.

When a breast 100B is accommodated in an accommodating space 21B of a breast accommodating apparatus 20B, the accommodating space 21B is formed into an adsorption negative pressure by a breast pump main body 10B to discharge breast milk from the breast 100; and

The accommodating space 21B is formed with a sustaining negative pressure by the breast pump body 10B such that the breast accommodating apparatus 20B is held at the breast 100B, wherein the value of the suction negative pressure is larger than that of the sustaining negative pressure, and the suction negative pressure and the sustaining negative pressure are alternately formed.

(i) Preheating a breast accommodating apparatus 20B and maintaining the temperature of the breast accommodating apparatus 20B in a suitable temperature range;

(ii) Causing a breast 100B to be held in an accommodation space 21B of the breast accommodating apparatus 20B; and

(Iii) A negative pressure environment is formed in the accommodating space 21B by a breast pump body 10B connected to the breast accommodating apparatus 20B to discharge breast milk from the breast 100.
