detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

Embodiment one

The breast pad 1 provided in this embodiment is used for a breast pump. When in use, it is inserted into the cover body and buckled on the breast to directly contact the breast. The shape of the breast pad 1 is the same as that of the existing breast pump, both in the shape of a horn shape. The breast pad 1 in this embodiment, as shown in FIGS. Evenly distributed on the inner wall of the pad 1, as shown in Figure 1, in the shape of petals. When the breast pump pumps milk, these flexible diaphragms 101 are used to squeeze the lactiferous sinus of the breast. Before the breast pump starts sucking milk, as shown in FIG. 2 , the flexible diaphragm 101 is in a natural state (slightly protruding from the inner wall of the breast pad 1 ). As shown in FIG. 5 , the breast 7 is placed in the breast pad 1 , and the flexible membrane 101 has not compressed the breast 7 . After the breast pump starts sucking milk, as shown in FIG. 3 , the flexible diaphragm 101 protrudes away from the inner wall of the breast pad 1 and is directly pressed against the lactiferous antrum 701 . Breast pads for existing breast pumps are mostly made of rubber or silica gel. The same is true for the breast pad 1 in this embodiment. The flexible diaphragm 101 can also be made of rubber or silica gel, and these flexible diaphragms 101 can be connected with the breast pad 1. into one. The flexible diaphragm 101 is made of rubber or silicone material, which can greatly reduce the damage to the breast when squeezing the lactiferous antrum.

The setting of the flexible diaphragm 101 is more in line with the physiological structure of female breasts. During the process of sucking milk by the breast pump, the flexible diaphragm 101 squeezes the lactiferous sinus of the breast, which is helpful for the extrusion of breast milk and improves the suction capacity of the breast pump. Increases milk efficiency and shortens pumping time, thereby reducing the likelihood of sore or deformed (elongated) nipples during pumping.

In this embodiment, in order to ensure that the flexible membrane 101 on the breast pad 1 can fit the lactiferous sinus as closely as possible when squeezing the lactiferous sinus, the breast pump cover is designed as follows:

As shown in Figures 1 to 3, the cover body includes the above-mentioned breast pad 1 and a trumpet-shaped breast shield 2, the breast pad 1 is placed in the breast shield 2, and there is a gap between the outer wall of the breast pad 1 and the inner wall of the breast shield 2. Gap 3. As shown in FIG. 4 , a through hole 201 is opened at a position corresponding to a flexible diaphragm 101 on the breast shield 2 . The breast pad 1 is placed in the breast shield 2, and the two together constitute the shield body, and the gas is filled through the through hole 201 on the breast shield 2 to make the flexible diaphragm 101 bulge, fit the lactiferous sinus as much as possible, and strengthen the extrusion The strength of the lactiferous sinus further promotes the discharge of breast milk. In order to avoid air leakage when inflating into the gap 3, then, preferably, there is a seal between the corresponding ends of the breast pad 1 and the breast shield 2, that is, the large mouth end of the breast pad 1 and the large mouth end of the breast shield 2 Seal between the small mouth end of the breast pad 1 and the small mouth end of the breast shield 2 .

As shown in Figure 5, when the breast pump is in use, the cover body is buttoned and covered on the breast 7. In order to avoid damage to the breast and reduce the extrusion of the cover body to the breast, preferably, as shown in Fig. As shown in 4, an annular soft cover 4 is arranged at the joint between the big mouth end of the breast pad 1 and the big mouth end of the breast shield 2, and the annular soft cover 4 is coaxial with the breast pad 1 and the breast shield 2. The ring-shaped soft cover 4 can effectively reduce the compression of the breast by the cover body, thereby protecting the breast.

This embodiment also provides a breast pump equipped with the above-mentioned cover body. As shown in Figure 4, the vacuum pump 6 in the breast pump communicates with the small mouth end of the cover body, and the feeding bottle 5 communicates with the inner cavity of the cover body. Close to the small mouth end of the cover body, the squeeze pump communicates with the through hole 201 on the breast shield 2 in the cover body through the tube body (not shown in the figure). The breast pump is additionally equipped with a squeeze pump connected to the through hole on the breast shield, which provides a power source for inflating the through hole. When the breast pump is sucking milk, the evacuation action of the vacuum pump 6 lags behind the inflating and squeezing action of the squeeze pump, that is, squeeze first and then suck, and so on, the flexible diaphragm 101 first squeezes the lactiferous antrum to stimulate The milk is discharged, and then the vacuum pump 6 pumps the milk to the feeding bottle 5, which greatly improves the efficiency of sucking milk. In this embodiment, the suction port in the vacuum pump 6 is coaxial with the small mouth end of the cover body, and the negative pressure airflow when pumping the emulsion quickly and smoothly flows from the large mouth end of the cover body to the small mouth end and then to the vacuum pump. The biggest advantage of this design is that the airflow is sent to the vacuum pump 6 in a straight line as far as possible, so as to reduce power loss and ensure that the milk will not flow back into the vacuum pump 6 .

In addition to using a squeeze pump to inflate the gap 3 through the through hole 201 to expand the flexible diaphragm 101, a hose can also be connected to the through hole 201. Then, place the hose in the mother's mouth and blow air into the through hole 201 to inflate the flexible membrane 101 . Likewise, the evacuation action of the vacuum pump 6 lags behind the blowing and squeezing action.

Embodiment two

In this embodiment, a plurality of flexible diaphragms 101 are replaced by a ring-shaped elastic body, which is arranged on the inner wall of the breast pad and is coaxial with the breast pad. When the breast pump pumps milk, this ring-shaped elastic body is used to squeeze the lactiferous sinus of the breast. Before the breast pump starts pumping, the ring-shaped elastomer is in its natural state (slightly protruding from the inner wall of the breast pad). After the breast pump starts sucking milk, the annular elastic body protrudes away from the inner wall of the breast pad and directly squeezes against the lactiferous antrum. Like the flexible diaphragm 101, the ring-shaped elastic body can be made of rubber or silicone, and these ring-shaped elastic bodies can be integrated with the breast pad.

In this embodiment, a through hole is opened at a position corresponding to the annular elastic body on the breast shield 2 in the shield body.

Except for the above structure, other structures are the same as the first embodiment.

Through examples 1 and 2, we can easily see that both the flexible diaphragm 101 and the annular elastic body are used to squeeze the lactiferous sinus of the breast. The squeezing body of the sinus can help the breast pump to promote the expression of milk during the pumping process. The gas is blown in through the through hole on the breast shield to make the extruding body bulge, which is beneficial to enhance the strength of extruding the lactiferous antrum and further promote the discharge of breast milk.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. All modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the claims of the present invention.
