Description

Medical atomizer

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a medical atomizer.

Background

The atomized inhalation therapy is an important and effective therapy method in the respiratory system disease therapy, the atomized inhalator is adopted to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and the lung for deposition in a respiratory inhalation mode, thereby achieving the aim of painless, rapid and effective therapy. The medical atomizer is mainly used for treating various upper and lower respiratory system diseases, such as common cold, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases in trachea, bronchus, alveolus and thoracic cavity. Good atomizers need to have stable spray, fine and uniform droplets, high atomization efficiency, and the like.

The ultrasonic atomizer applies ultrasonic sound energy to change liquid medicine into fine aerial fog which is inhaled by respiratory tract to achieve the purpose of treatment. Due to the characteristics of the ultrasonic atomizer, most of the generated medicine particles can only be deposited in the upper respiratory tract such as the oral cavity, the throat and the like, and the deposition amount of the lung is small. Therefore, ultrasonic nebulizers are mainly used for the treatment of upper respiratory tract diseases.

Meanwhile, the ultrasonic atomizer generates large fog particles, the atomization is fast, and the ultrasonic atomizer can quickly enter a treatment state; but at the same time, it can carry excessive moisture. The patient inhales excessive water vapor, so that the thick and dry secretion which partially blocks the bronchus in the respiratory tract originally expands after absorbing water, the resistance of the respiratory tract is increased, and the phenomenon of oxygen deficiency can be possibly generated, so that poor treatment experience is caused; more seriously, if a large amount of water enters the patient's lungs, it may also cause hydrops in the patient's lungs. In addition, the ultrasonic atomizer can cause the liquid medicine to form water drops to be hung on the wall of the inner cavity, which causes the waste of the medicine and increases the medicine cost.

Therefore, there is a need for a medical vaporizer that has good therapeutic effects without adverse side effects.

The same or similar reference numbers in the drawings identify the same or similar elements.

Detailed Description

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the invention.

Referring to fig. 1, fig. 1 shows a medical vaporizer according to the present invention. The medical vaporizer includes: the nasal mask comprises a shell 10, a medicine cup 20, a water tank 30, an ultrasonic generator 40, a central control device 50, a corrugated pipe 60 and a nasal mask 70.

The nasal mask 70 is connected with the mist discharge port 11 of the housing 10 through the bellows 60. The atomized liquid medicine is discharged through the mist discharge port 11 to the nasal mask 70. However, the atomized medicine mist still contains water, and if a large amount of water enters the lung, the water is easy to cause hydrops in the lung, and more harm is brought to a user. Therefore, the medical atomizer provided by the invention is provided with the drying device 12 in the mist outlet 11, and the drying device 12 is used for absorbing the excessive moisture contained in the medicine mist.

Preferably, at least three layers of drying agents are arranged in the drying device 12; the drying agent sequentially comprises a color-changing silica gel layer, an anhydrous calcium chloride layer and a color-changing silica gel layer from the air inlet direction to the air outlet direction of the fog outlet 11. The first layer adopts a color-changing silica gel layer, and the anhydrous silica gel not only can realize the technical effect of water absorption, but also can display the amount of water through color change; the second layer is an anhydrous calcium chloride layer, calcium chloride particles have excellent absorption characteristics, hardening does not occur after water absorption, and the medicine mist cannot be influenced to pass through; the third layer is still the silica gel layer that discolours, because the medicine fog only contains a small amount of moisture behind the second floor, the third layer can continue to absorb to the dewatering effect of visual display medicine fog.

Since the medicines contained in the medicine cups 20 have different properties, the drying agent in the drying device 12 provided by the present invention is different according to the properties of the medicines in order to achieve the optimal dewatering and drying effects. When the medicine cup 20 contains alkaline medicines, the drying agent sequentially comprises a color-changing silica gel layer, an anhydrous calcium chloride layer, a solid sodium hydroxide layer and a color-changing silica gel layer from the air inlet to the air outlet direction of the mist outlet 11. The alkaline drying agent does not influence the property of the alkaline medicinal fog while drying. When the medicine cup 20 contains acidic medicines, the drying agent sequentially comprises a allochroic silica gel layer, an anhydrous calcium chloride layer, an anhydrous magnesium sulfate layer and an allochroic silica gel layer from the air inlet direction to the air outlet direction of the fog outlet 11. The acidic desiccant can dry without affecting the property of the acidic medicinal mist.

More preferably, a filtering device is arranged among the plurality of layers of drying agents. The filter equipment is used for cutting apart a plurality of desiccants, simultaneously, can also further filter the impurity in the medicine fog.

The medicine cup 20, the water tank 30, the ultrasonic generator 40 and the central control device 50 are all arranged in the shell 10. The medicine cup 20 is disposed above the water tank 30. The bottom of the medicine cup 20 is provided with a sound-transmitting membrane 21. Preferably, the sound-transmitting membrane 21 has an arc shape. The arc-shaped sound-transmitting membrane 21 can enable the liquid medicine after ultrasonic atomization to be more concentrated and better lead to the mist discharge port 11.

The ultrasonic generator 40 is disposed below the water tank 30, and a crystal transducer is disposed between the ultrasonic generator 40 and the water tank 30. The ultrasonic generator 40 outputs high-frequency electric energy to make the crystal transducer at the bottom of the water tank 30 generate ultrasonic sound energy, and the sound energy vibrates the sound-transmitting membrane 21. The sound-permeable membrane 21 applies vibration to the medicine in the medicine cup 20 to break the surface tension and inertia of the medicine liquid, so that the medicine liquid becomes fine medicine mist, and is finally inhaled by the patient through the nasal mask 70.

Preferably, the ultrasonic vibration frequency of the medical atomizer is greater than 3.0 Mhz. The vibration frequency of an ultrasonic generator in the existing ultrasonic atomizer is usually about 2.4Mhz, and the generated fog particles are large, the atomization speed is slow and the atomization effect is poor because the vibration frequency is low. The invention adopts the vibration frequency more than 3.0Mhz, and can achieve better atomization effect; moreover, the vibration frequency selected by the invention is safe and reliable, and cannot cause harm to users.

The central control device 50 is disposed below the ultrasonic generator 40, and is electrically connected to the ultrasonic generator for driving and controlling the vibration of the ultrasonic generator 40.

Preferably, in order to know the amount of the liquid medicine in the medicine cup 20 in real time, the medical vaporizer further includes: a liquid level sensor of the liquid medicine. The liquid level sensor of the liquid medicine is arranged on the medicine cup 20 and is electrically connected with the central control device 50; the liquid level sensor is used for sensing the liquid level of the liquid in the medicine cup 20. When the liquid level is too low, the discharge effect of the mist is affected, and the atomizer itself is damaged, so that the liquid level sensor is necessary.

Preferably, a side door 13 is disposed on one side of the housing 10, and the size of the side door 13 matches with that of the medicine cup 20. When the medicine liquid needs to be added or replaced, the side door 13 is opened, and the medicine cup 20 is taken out. The arrangement of the side door 13 greatly simplifies the operations of changing medicine, adding medicine, cleaning the medicine cup 20 and the like. More preferably, a transparent chemical liquid display device may be provided in the side door 13 so as to communicate with the inside of the cup 20. According to the principle of the communicating vessel, the liquid medicine display device can display the liquid medicine height in the medicine cup 20 in real time.

In order to know the amount of water in the water tank 30 in real time, a water level display device is arranged outside the shell 10; the water level display device is communicated with the water tank 30 and instantly displays the water level in the water tank 30. The water level display device, like the liquid medicine display device, also utilizes the principle of a communicating vessel.

A water filling port 16 is arranged on the side wall of the housing 10, and the water filling port 16 is communicated with the water tank 30 through a water conveying pipeline 17. The need for cleaning the water tank 30 is also low, as the added water in the water tank 30 does not need to be changed for different drugs. Therefore, the present invention selects a solution in which the water filling port 16 is provided on the side wall of the case 10, and does not select a solution in which the side door is provided. The design can not only well meet the requirement of adding water into the water tank 30, but also simplify the water adding operation; meanwhile, the production process is simple and easy to realize, and the production cost is also reduced.

In order to facilitate the mist to leave the liquid in time, the liquid needs to have a partial free surface, i.e. the liquid needs the action of gravity to have a small divergence. That is, when the atomizer is in a vertical state, the atomizing effect can be optimized. However, during use, it is difficult for the patient to confirm whether the nebulizer is in a vertical state. Therefore, preferably, the medical vaporizer includes: a gravity sensor; the gravity sensor is arranged inside the shell 10 and is electrically connected with the central control device 50; the gravity sensor is used for sensing the vertical degree of the medical atomizer.

Although the atomization effect is best when the atomizer is in a perfect vertical state, in practical application, it is difficult to achieve an ideal state, and therefore, the sensing angle range of the gravity sensor is in the range of 90 ° ± 2 °. When the angle exceeds the range, the gravity sensor gives an alarm, and the alarm signal can be a sound signal, an optical signal, vibration and the like; within the angle range, the gravity sensor defaults the medical atomizer to work normally.

The medical vaporizer includes a fan 80; the fan 80 is arranged below the medicine cup 20 and beside the water tank 30, and is positioned at one side of the mist outlet 11. The fan 80 is electrically connected to the central control device 50. When the device needs to work, the central control device 50 controls the fan 80 to start rotating, and the atomized medicine mist is blown out from the upper mist outlet 11. Since the mist is discharged from the mist discharge port 11, the fan 80 is preferably provided on the side of the mist discharge port 11.

In order to avoid the waste of the medicine and the jumping of the incompletely atomized medicine liquid, it is preferable that a baffle 14 is provided above the medicine cup 20 on a side away from the mist discharge port 11. The baffle 14 is used for blocking the incompletely atomized liquid medicine beads, so that the liquid medicine beads fall into the medicine cup 20 again to be atomized again.

A guide plate 15 is arranged in the shell 10 and above the mist discharge port 11 at a certain angle. The arrangement of the guide plate 15 can lead the ultrasonically atomized liquid medicine to the mist discharge port 11 more intensively and finally discharge the liquid medicine through the mist discharge port 11.

More preferably, the medical vaporizer may further include a wireless communication device electrically connected to the central control device 50. With the development of the internet, remote diagnosis and treatment is a trend of future development. The wireless communication device can send the working state of the medical atomizer to the receiving end. The receiving end includes but is not limited to: computer terminal, mobile terminal APP and/or cloud server. The operating state of the medical vaporizer includes operating parameters of the medical vaporizer, such as: frequency, working time, medication used, on time, etc.; also included are user parameters such as: case, prescription, indication, medical order, and the like.

The medical atomizer provided by the invention has the advantages of small fog particles, high atomization speed, low water content after liquid medicine gasification, good patient experience, low cost and easy popularization.
