Description

Technical Field

[0001] The utility model relates to the technical field of atomizers, in particular to a medical atomizer assembly. Background Art

[0002] Medical nebulizers are primarily used to treat various upper and lower respiratory system conditions, such as colds, fevers, coughs, asthma, sore throats, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases affecting the trachea, bronchi, alveoli, and chest cavity. Nebulizer inhalation therapy is an important and effective treatment for respiratory diseases. A nebulizer inhaler atomizes liquid medication into tiny particles, which are then inhaled into the respiratory tract and deposited in the lungs, achieving painless, rapid, and effective treatment.

[0003] There is a type of atomizer currently available on the market. Its main principle is to eject compressed air at high speed through a narrow nozzle. According to Bernoulli's principle, the airflow speed is high and the pressure is low at the nozzle opening, which creates a pressure differential. Under the action of this pressure differential, the liquid medicine is drawn through the narrow passage to the vicinity of the nozzle, where the airflow breaks the liquid medicine into a mist. Existing atomizer atomizer cups mainly come in the following two types: the first has a concave bottom structure, in which the liquid medicine is concentrated in the middle position for absorption; the other has a flat bottom structure, with a flat thin plate set above the bottom, forming a narrow passage between the thin plate and the bottom, facilitating the absorption of the liquid medicine from the entire atomizer cup. However, during current use, it has been found that when the atomizer cup is tilted, when there is less liquid medicine, it will be concentrated in the lowest corner of the atomizer cup. In the first structure, the liquid medicine no longer contacts the passage for absorption, making it impossible to absorb. In the second structure, due to the tilt of the device, the area of ​​the passage for absorption of the liquid medicine increases, and the height difference between the liquid medicine and the nozzle increases, making it impossible to absorb the liquid medicine when the pressure difference is constant. Utility Model Content

[0004] 1. Technical problem to be solved: It is difficult for the existing atomizer to absorb the small amount of residual liquid medicine when it is placed at an angle.

[0005] In view of the above technical problems, the utility model provides a medical atomizer assembly.

[0006] 2. Technical solution:

[0007] A medical nebulizer assembly includes an atomizing cup and a sleeve. A nozzle that is thin at the top and thick at the bottom is provided at the center above the inner bottom of the atomizing cup. The nozzle is connected to the compressed air connector at the bottom of the atomizing cup. The sleeve includes a sleeve cap and an annular thin sheet at its bottom. The sleeve cap is sleeved on the nozzle. An atomized liquid outlet is provided at a position of the sleeve cap near the nozzle outlet. A liquid medicine absorption passage is reserved between the sleeve cap and the outer side surface of the nozzle. A plurality of radial isolation strips are provided at the bottom of the thin sheet. The isolation strips are tightly attached to the upper surface of the inner bottom of the atomizing cup. A slit is reserved between the thin sheet and the side wall of the atomizing cup.

[0008] Furthermore, the upper surface of the inner bottom of the atomizing cup and the lower surface of the sheet are both flat horizontal surfaces, the isolation strips are fan-shaped structures, and separated channels are formed between adjacent isolation strips.

[0009] Furthermore, a plurality of extrusion strips are evenly arranged on the inner side wall of the sleeve cap, and the nozzle is clamped between the plurality of extrusion strips.

[0010] Furthermore, the atomizer cup and the sleeve are both made of transparent medical plastic material.

[0011] Furthermore, a groove is provided at the bottom of the atomizing cup, and a compressed air connector is provided inside the groove.

[0012] Furthermore, the top of the atomizer cup is an insertion port, and the atomizer breathing mask is inserted into the insertion port.

[0013] 3.Beneficial effects:

[0014] The medical nebulizer assembly of the present invention is provided with a plurality of radially distributed isolation strips at the bottom of the thin sheet. The isolation strips contact the upper surface of the inner bottom of the nebulizer cup to form a plurality of channels. When the nebulizer cup is tilted, the medicine concentrated in one corner of the bottom of the nebulizer cup will be adsorbed through several of the channels, and the adsorption surface is small. In addition, the channels that are not in contact with the medicine will inhale air, and the flow rate of the air will increase after passing through the gradually narrowing channels. According to the Bernoulli principle, a large pressure difference will also be generated between the end and the front end of the channel that is in contact with the medicine, thereby increasing the suction force. Therefore, after the isolation strips are provided, a small amount of residual medicine can be more effectively absorbed when the nebulizer cup is tilted, thereby reducing the residual medicine, avoiding the waste of medicine, and increasing the treatment effect.

[0019] The present invention will be described in detail below with reference to the accompanying drawings.

[0020] As attached Figure 1 To the attached Figure 4 As shown,

[0021] Example 1: A medical nebulizer assembly includes an atomizing cup 1 and a sleeve 2. A nozzle 3 that is thin at the top and thick at the bottom is provided at the center above the inner bottom of the atomizing cup 1. The nozzle 3 is connected to the compressed air connector 4 at the bottom of the atomizing cup 1; the sleeve 2 includes a sleeve cap 5 and an annular thin sheet 6 at its bottom. The sleeve cap 5 is sleeved on the nozzle 3. The sleeve cap 5 is provided with an atomized liquid outlet 7 near the outlet of the nozzle 3. A liquid medicine absorption passage is reserved between the sleeve cap 5 and the outer side surface of the nozzle 3. A plurality of radial isolation strips 8 are provided at the bottom of the thin sheet 6. The isolation strips 8 are tightly attached to the upper surface of the inner bottom of the atomizing cup 1, and a slit is reserved between the thin sheet 6 and the side wall of the atomizing cup 1.

[0022] The upper surface of the inner bottom of the atomizing cup 1 and the lower surface of the sheet 6 are both flat horizontal surfaces. The isolation bars 8 are fan-shaped structures, and adjacent isolation bars 8 form separated channels.

[0023] When the medical nebulizer assembly of this embodiment is in operation, the compressed air connector 4 is connected to the atomizing pump. High-pressure gas is injected from the compressed air connector 4 and ejected at high speed through the gradually tapering nozzle 3. According to Bernoulli's principle, the faster the flow rate, the lower the pressure. Under the action of atmospheric pressure, the liquid medicine contained in the atomizer cup 1 is drawn through the liquid medicine suction passage between the sleeve cap 5 and the nozzle 3 to the vicinity of the atomized liquid outlet 7. The liquid medicine is then dispersed into a mist by the high-speed ejected air. The above describes the atomization principle of the atomizer assembly of this embodiment. A significant improvement of this embodiment lies in the radial isolation strips 8 provided at the bottom of the thin sheet 6. When the amount of liquid medicine decreases and the atomizer cup 1 is tilted, the liquid medicine tends to concentrate at a corner of the bottom of the atomizer cup 1, increasing the height difference between the liquid medicine and the atomized liquid outlet 7. In the absence of the isolation strips 8, the liquid medicine must pass through the very large space between the thin sheet 6 and the inner bottom of the atomizer cup 1 to be further drawn from the liquid medicine suction passage to the vicinity of the atomized liquid outlet 7. Since the pressure difference generated during operation is constant, it is difficult for the liquid medicine to be drawn up, which can easily lead to waste. After the radial isolation strips 8 are provided, separated channels are formed between adjacent isolation strips 8. When the liquid medicine is concentrated in a corner of the bottom of the atomizer cup 1, it will pass through several of the channels and be adsorbed. The adsorption surface is small. In addition, the channels that are not in contact with the liquid medicine will inhale air. The flow rate of the air will increase after passing through the gradually narrowing channels. According to the Bernoulli principle, a large pressure difference will also be generated between the end and the front end of the channel that contacts the liquid medicine, thereby increasing the suction force. Therefore, after the isolation strips 8 are provided, a small amount of residual liquid medicine can be more effectively absorbed when the atomizer cup 1 is tilted.

[0024] Example 2:

[0025] A plurality of extrusion strips 9 are evenly arranged on the inner side wall of the sleeve cap 5, and the nozzle 3 is clamped between the plurality of extrusion strips 9. There is a gap between adjacent extrusion strips 9 to facilitate the passage of the liquid medicine.

[0026] Example 3:

[0027] The atomizer cup 1 and the socket 2 are both made of transparent medical plastic, making it easy to check the amount of liquid medicine inside. The bottom of the atomizer cup 1 is provided with a groove 10, and the compressed air connector 4 is located inside the groove 10. The atomizer cup 1 can be placed flat on a table.

[0028] Example 4:

[0029] The top of the nebulizer cup 1 is an insertion port, into which the nebulizer breathing mask is inserted. When the patient undergoes nebulizer treatment, the medicine liquid is first added to the nebulizer cup 1, and then the nebulizer breathing mask is installed. After the patient wears the breathing mask, the nebulizer pump can be turned on.

[0030] Although the present invention has been disclosed above in terms of preferred embodiments, they are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined by the claims of this application.
