Description

Technical Field

[0001] The present application relates to the technical field of medical supplies, and in particular to a nebulizer mask. Background Art

[0002] A nebulizer is an instrument that converts liquid into tiny droplets and is usually used to treat respiratory diseases such as asthma and bronchitis. Medical nebulizers are mainly used to atomize drugs into tiny particles, which are then inhaled into the respiratory tract and lungs for deposition, thereby achieving painless, rapid and effective treatment. Nebulizers are usually used in conjunction with masks, and patients can inhale the drug mist in the nebulizer through their mouths by wearing masks.

[0003] Existing nebulizer masks usually only include a mask body that covers the patient's mouth and nose, and the mask body is provided with an air inlet and an air outlet. The mask body and the nebulizer are usually directly connected only through a ventilation tube, one end of which is inserted into the nebulizer, and the other end is connected to the air inlet of the mask body. Since there is a lot of air in the ventilation tube, when the patient inhales using the nebulizer, part of the air enters the mouth first, and then the drug mist enters the mouth, so that the drug mist is diluted, and more drug mist will stay in the oropharynx, reducing the amount of medicine inhaled into the airway and lung tissue, resulting in reduced efficacy of the drug mist. Utility Model Content

[0004] In order to solve the problem of reduced efficacy of drug mist caused by reduced amount of drug inhaled into the airway and lung tissue, the present application provides a nebulizer mask.

[0005] The present application provides a nebulizer mask, which adopts the following technical solution:

[0006] A nebulizer mask comprises a mask body, the mask body is provided with an air inlet and an air outlet, and also comprises a spacer and a connector; one end of the spacer is provided with a medicine insertion port, and the other end of the spacer is provided with a medicine outlet; the connector is arranged at the end of the spacer close to the medicine outlet and is used to connect the medicine outlet and the air inlet; the spacer is provided with an inhalation valve at the medicine outlet, the inhalation valve is located on a side of the medicine outlet close to the mask body, the inhalation valve covers the medicine outlet and has the ability to deform away from the medicine outlet.

[0007] By adopting the above technical solution, since the inhalation valve covers the medicine outlet, the medicine mist sprayed by the inhalation medicine can be stored in the mist storage tank in advance and fully mixed with the air in the tank. When the patient inhales, the inhalation valve can open, the medicine mist can enter the mask body and be directly inhaled into the airway and lung tissue, the amount of medicine remaining in the oropharynx can be significantly reduced, the efficacy can be significantly increased, and the irritation of the medicine mist to the oropharynx can be greatly reduced. In addition, the problem of asynchrony between spraying and inhalation is solved. When the patient needs to inhale the medicine mist, there is always medicine mist in the mist storage tank for the patient to inhale, which is more convenient.

[0008] Optionally, the mist storage tank is provided with a support frame inside the medicine outlet, and the support frame divides the medicine outlet into a plurality of medicine outlet channels; the inhalation valve includes a fixed ring and a deformation sheet connected to the inner side of the fixed ring, the deformation sheet corresponds to the medicine outlet channels one by one and covers the medicine outlet channels, and the edge of the deformation sheet abuts against the support frame.

[0009] By adopting the above technical solution, the inhalation flap is divided into a plurality of deformable pieces, each of which can correspond to a drug outlet channel and cover it. When the patient inhales, the deformable pieces can deform individually under the action of negative pressure, thereby opening the drug outlet. Compared with the overall deformation of the inhalation flap, it is easier to deform individually because the angle of the deformable piece is smaller.

[0010] Optionally, the spacer tank is provided with positioning posts in the circumferential direction of the medicine outlet, and the fixing ring is provided with positioning holes corresponding to the positioning posts one by one and used for inserting the fixing ring.

[0011] By adopting the above technical solution, the inhalation valve is installed on the mist storage tank through the cooperation of the positioning column and the positioning hole, and the installation method is relatively simple; and the fixing ring is not easy to deform after being fixed by the positioning column, and the fixing ring can always fit the end face of the mist storage tank, and the sealing performance is better.

[0012] Optionally, the connector includes a sleeve section and a plug-in section connected to the sleeve section; the sleeve section has an installation cavity for inserting and installing the end of the fog storage tank, the plug-in section is plug-fitted with the air inlet and has a through hole connected to the installation cavity and used for allowing the medicine mist to pass through; a clamping block is circumferentially arranged on the bottom surface of the installation cavity, the clamping block abuts against the fixing ring and presses the fixing ring against the end surface of the fog storage tank.

[0013] By adopting the above technical solution, after the inhalation valve is fixed by the positioning column, it is pressed against the end face of the fog storage tank by the pressing block, so that the fixing ring of the inhalation valve is further fixed, thereby improving the sealing performance between the fixing ring and the end face of the fog storage tank.

[0014] Optionally, the connector is provided with a mounting sleeve on the bottom surface of the mounting cavity, and the end of the mist storage tank has a locking ring portion that is plugged into the mounting sleeve; the locking ring portion is circumferentially provided with locking blocks; and the inner wall of the mounting sleeve is provided with a locking groove for the locking block to be rotatably inserted.

[0015] By adopting the above technical solution, the locking block can be rotated and inserted into the locking groove, and the locking block can be limited by the inner wall of the locking groove, so that the locking block is not easy to fall out of the locking groove, so that the connection head is more firmly connected to the mist storage tank, and the installation method of the above connecting head on the mist storage tank is relatively simple.

[0016] Optionally, the locking groove includes a locking channel and an entry channel, the locking channel is arranged along the circumference of the mounting sleeve, and the entry channel passes through the end surface of the mounting sleeve to the locking channel.

[0017] By adopting the above technical scheme, the structural form of the locking groove is specifically disclosed. The locking block enters the locking channel from the entry channel along the axial direction of the connecting head, and then the connecting head is rotated. The locking block can rotate circumferentially in the locking channel. Since the locking block is limited axially, the locking block is locked in the locking channel, and the locking block is not easy to withdraw from the locking channel.

[0018] Optionally, the locking block has a protruding portion, the mounting sleeve has a recessed groove in the locking channel, and the protruding portion is snap-fitted with the recessed groove.

[0019] By adopting the above technical solution, when the locking block is locked in the locking channel, the protrusion on the locking block can be engaged in the recessed groove in the locking channel, so that the locking block is further locked and the locking block is not easy to rotate circumferentially.

[0020] Optionally, a sealing gap is formed between the mounting sleeve and the inner wall of the mounting cavity, and a sealing gasket is arranged in the sealing gap, and the connector presses the sealing gasket against the end face of the mist storage tank.

[0021] By adopting the above technical solution, when the connector is installed on the spacer, the connector can press the sealing gasket against the end face of the spacer, so that when the patient inhales, the medicine mist is not easy to overflow from the gap between the connector and the spacer; and a U-shaped sealing structure is formed between the locking ring and the mounting sleeve. Under the action of the above double sealing structure, the sealing ability of the nebulizer mask is better.

[0022] Optionally, the mask body is provided with an exhaust valve sheet at the air outlet, and the exhaust valve is located on the outside of the mask body. The exhaust valve covers the air outlet and has the ability to deform in a direction away from the mask body.

[0023] By adopting the above technical solution, when the patient inhales, the inhalation valve is deformed and opens the medicine outlet, while the exhaust valve covers the outlet, so that only the medicine mist in the mist storage tank can be absorbed, and the inhalation ability of the medicine mist is better; when the patient exhales, the inhalation valve covers the medicine outlet, and the exhaust valve is deformed and opens the outlet, at this time the carbon dioxide exhaled by the patient can be discharged from the outlet, which is more convenient.

[0024] Optionally, the aerosol storage tank is made of anti-static material.

[0025] By adopting the above technical solution, the antistatic material is not easy to adsorb drug particles, so that the drug mist is not easy to be adsorbed on the inner wall of the mist storage tank, and the drug mist can be absorbed by the patient.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The embodiment of the present application discloses a nebulizer mask.

[0037] Reference Figure 1 The nebulizer mask includes a mask body 1, a connector 2 and a spacer 3. The mask body 1 is worn on the patient's mouth and nose to cover the mouth and nose. One end of the spacer 3 is connected to the nebulizer, and the other end is connected to the mask body 1 through the connector 2. The nebulizer can atomize the medicine and then introduce it into the spacer 3 for storage, and the patient can directly absorb the medicine mist from the spacer 3.

[0038] Reference Figure 1 The shape of the mask body 1 is the same as the contour of the human mouth and nose, and can fit the patient's skin well. The mask body 1 is provided with an air inlet 11 and an air outlet 12, and the air outlet 12 is above the air inlet 11. When the patient wears the mask body 1, the air inlet 11 faces the patient's mouth, and the air outlet 12 faces the patient's nose. The patient can inhale the medicine mist from the air inlet 11 and exhale carbon dioxide from the air outlet 12.

[0039] Reference Figure 1 and Figure 2 The mask body 1 is provided with an exhaust valve sheet 13 at the air outlet 12, and the exhaust valve sheet 13 includes a fixing column 131 and a film portion 132. The fixing column 131 is penetrated through the air outlet 12, and the exhaust valve sheet 13 is installed at the air outlet 12 through the fixing column 131. The film portion 132 is a circular film, which is integrally connected to one end of the fixing column 131 away from the inner cavity of the mask body 1, and the film portion 132 is arranged on the outside of the air outlet 12 and covers the air outlet 12.

[0040] Reference Figure 1 and Figure 2The film part 132 has the ability to deform. When the patient exhales, the air pressure inside the mask body 1 is greater than the air pressure outside the mask body 1. The circumferential edge of the film part 132 is deformed and bent in the direction away from the air outlet 12 due to the negative pressure, thereby opening the air outlet 12. After the air outlet 12 is connected inside and outside, the carbon dioxide exhaled by the patient can be discharged from the air outlet 12; when the patient inhales, the air pressure inside the mask body 1 is less than the air pressure outside the mask body 1. The atmospheric pressure presses the film part 132 against the air outlet 12, and the air outlet 12 is covered again, so that the patient cannot inhale from the air outlet 12. Thus, the ability of one-way exhaust is achieved.

[0041] Reference Figure 1 and Figure 3 The connector 2 includes a sleeve section 21 and a plug section 22, and the plug section 22 is integrally connected to the sleeve section 21. The shape of the plug section 22 is adapted to the shape of the air inlet 11, and the plug section 22 can be inserted into the air inlet 11. The plug section 22 is coaxially provided with a through hole 221. The sleeve section 21 is a hollow cylinder and has a mounting cavity 211. The mounting cavity 211 is connected to the through hole 221.

[0042] Reference Figure 1 and Figure 4 The spacer 3 is a hollow cylinder, and is made of antistatic material, which is not easy to absorb drug mist particles. A drug insertion port 31 is provided at one end of the spacer 3, and a drug outlet 32 ​​is provided at the other end. The drug insertion port 31 can be inserted into the pipeline of the atomizer, and the drug mist generated by the atomizer can enter and be stored in the inner cavity of the spacer 3. When the drug mist needs to be used, the drug mist can be discharged from the drug outlet 32.

[0043] Reference Figure 1 and Figure 4 One end of the spacer 3 having the medicine outlet 32 ​​cooperates with the connector 2, and the end of the spacer 3 is inserted into the mounting cavity 211, so that the inner cavity of the spacer 3, the mounting cavity 211, the through hole 221, and the inner cavity of the mask body 1 are connected in sequence. When the patient inhales, the medicine mist enters from the medicine insertion port 31, flows through the inner cavity of the spacer 3, the mounting cavity 211, the through hole 221, and the inner cavity of the mask body 1, and then enters the patient's oral cavity.

[0044] Reference Figure 4, the spacer 3 is provided with interconnected support frames 321 in the circumferential direction of the medicine outlet 32, and the support frames 321 divide the medicine outlet 32 ​​into a plurality of medicine outlet channels 322, and the medicine outlet channels 322 are arranged in a circle. The spacer 3 is also provided with an inhalation valve 33 at the medicine outlet 32, and the inhalation valve 33 is located on the outer end surface of the spacer 3. The inhalation valve 33 is a circular thin sheet, which includes a fixing ring 331 and a deformation sheet 332. The fixing ring 331 is in the shape of a circular ring, and its diameter is larger than the diameter of the medicine outlet 32. The deformation sheet 332 is fixedly connected to the inner side of the fixing ring 331 and is evenly distributed along the inner circumferential direction of the fixing ring 331. The deformation sheet 332 corresponds to the medicine outlet channel 322 one by one and covers the medicine outlet channel 322, and the edge of the deformation sheet 332 abuts against the support frame 321. The deformable sheet 332 has a deformability and can be bent and deformed in a direction away from the medicine outlet 32 ​​, thereby opening the medicine outlet 32 ​​.

[0045] Reference Figure 3 and Figure 4 In order to make the inhalation valve 33 more firmly installed at the medicine outlet 32, the spacer 3 is provided with a plurality of positioning posts 34 in the circumference of the medicine outlet 32, and the fixing ring 331 is provided with a plurality of positioning holes 333 corresponding to the positioning posts 34 in the circumference, and the fixing ring 331 can be inserted and fixed on the positioning posts 34 through the positioning holes 333. In addition, the connector 2 is provided with a pressing block 212 in the circumference of the installation cavity 211. When the spacer 3 is matched with the connector 2, the pressing block 212 abuts against the fixing ring 331 and presses the fixing ring 331 against the end face of the spacer 3.

[0046] Reference Figure 1 and Figure 4 By setting the inhalation flap 33, when the patient inhales, the air pressure in the inner cavity of the spacer 3 is greater than the air pressure outside, and the inhalation flap 33 is deformed under the action of the air pressure in the spacer 3, thereby opening the medicine outlet 32. At this time, the medicine mist can enter the mask body 1 from the spacer 3 and be inhaled by the patient. When the patient exhales, the air pressure in the inner cavity of the spacer 3 is less than the air pressure outside, and the inhalation flap 33 is pressed against the medicine outlet 32 ​​by the atmospheric pressure, thereby covering the medicine outlet 32. At this time, the carbon dioxide exhaled by the patient is not easy to enter the spacer 3.

[0047] Reference Figure 2 and Figure 4 The inhalation flap 33 can be linked with the exhaust valve sheet 13. When the patient inhales, the inhalation flap 33 opens and the exhaust valve sheet 13 closes, and the patient can inhale the medicine mist. When the patient exhales, the inhalation flap 33 closes and the exhaust valve sheet 13 opens, and the carbon dioxide exhaled by the patient can be discharged through the outlet 12. Through the above structure, a cycle of inhalation and exhalation is formed.

[0048] Reference Figure 3 and Figure 4In order to make the connection between the connector 2 and the mist storage tank 3 more sealed and prevent the medicine mist from overflowing from the connection, a sealing structure is provided between the two. The connector 2 is provided with a mounting sleeve 213 on the inner bottom surface of the mounting cavity 211. The mounting sleeve 213 is located outside the pressing block 212, and the shape of the mounting sleeve 213 is a hollow cylinder. The end of the mist storage tank 3 is provided with a locking ring 35, and the shape of the locking ring 35 is a circular ring. The locking ring 35 is plugged into the mounting sleeve 213.

[0049] Reference Figure 3 and Figure 4 The locking ring portion 35 is provided with a locking block 351 in the circumferential direction, and the inner wall of the mounting sleeve 213 is provided with a locking groove 214 in the circumferential direction. The locking groove 214 includes a locking channel 2141 and an entry channel 2142. The locking channel 2141 is provided along the circumferential direction of the mounting sleeve 213, and the entry channel 2142 penetrates the end surface of the mounting sleeve 213 to the locking channel 2141. When the connector 2 is matched with the spacer 3, the locking block 351 can slide along the entry channel 2142 into the locking channel 2141, and be locked in the locking channel 2141 by rotating the connector 2.

[0050] Reference Figure 3 and Figure 4 The locking block 351 has a protrusion 352, and the mounting sleeve 213 is provided with a recessed groove 2143 in the locking channel 2141. The protrusion 352 is engaged with the recessed groove 2143. Through the cooperation between the protrusion 352 and the recessed groove 2143, the locking block 351 is further locked in the locking channel 2141 more firmly, and the connection between the mist storage tank 3 and the connector 2 is tighter.

[0051] Reference Figure 3 and Figure 4 A sealing gap 215 is formed between the mounting sleeve 213 and the inner wall of the mounting cavity 211. The sealing gap 215 is annular. A sealing gasket 216 is arranged in the sealing gap 215. When the spacer tank 3 is connected to the connector 2, the connector 2 can press the sealing gasket 216 against the end face of the spacer tank 3, thereby further improving the sealing ability between the spacer tank 3 and the connector 2.

[0052] Combination Figures 1 to 4 The implementation principle of the nebulizer mask of the embodiment of the present application is as follows: since the inhalation valve 33 covers the medicine outlet 32, the medicine mist sprayed by the inhalation medicine can be pre-stored in the mist storage tank 3 and fully mixed with the air in the tank. When the patient inhales, the inhalation valve 33 can be opened, the exhaust valve plate 13 can be closed, and the medicine mist can enter the mask body 1 and be directly inhaled into the patient's mouth. When the patient exhales, the inhalation valve 33 can be closed, the exhaust valve plate 13 can be opened, and the carbon dioxide exhaled by the patient can be discharged from the outlet 12.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
