Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical net-type atomizer atomizing medicine mist storage tank. Background Art

[0002] Medical nebulizer is a medical device used to achieve aerosol inhalation therapy.

[0003] Publication No. CN108379702B discloses a medical nebulizer. Its technical solution includes: a drug reservoir, a mist collecting tank, and an atomization generating assembly.

[0004] In response to the relevant content mentioned above, the inventor of the utility model believes that the following technical defects exist: the existing atomizing medicine mist storage tanks mostly form an air inlet channel and an air outlet channel that are connected to each other in the space surrounded by a single shell, and the structural design and application of the existing medicine mist storage tanks are invisibly affected by the above-mentioned original structure, thereby limiting the development and application scope of the existing atomizing medicine mist storage tanks. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a medical net-type atomizer atomizing medicine mist storage tank.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a medical mesh nebulizer atomizing medicine mist storage tank, comprising: an atomizing medicine mist storage tank, which is formed with an atomizing liquid medicine mist inlet and an air inlet, the atomizing liquid medicine mist inlet and the air inlet are arranged at the tail of the atomizing medicine mist storage tank, an oxygen access port is provided below the air inlet, the shell of the atomizing medicine mist storage tank and the front end of the atomizing medicine mist storage tank jointly form an atomizing medicine mist storage chamber connected to the atomizing liquid medicine mist inlet, the air inlet, the oxygen access port and provided with a plurality of perforations; further comprising a first breathing piece, a second breathing piece and a third breathing piece, the first breathing piece comprising a joint end, an inlet silicone plug and a mating end, the second breathing piece comprising a breathing port, a first soft cushion, a second soft cushion, an air outlet and a mounting plate; further comprising an atomizing device and a wearing assembly.

[0007] Preferably, the air inlet is located at the center of the air inlet member, and the area of the air inlet accounts for 20% to 30% of the area of the rear end of the atomizing spacer.

[0008] Preferably, the first respiratory component further includes an air intake valve plate, which is installed in the atomizing mist storage chamber and is located corresponding to the air inlet, and is used to allow air flow to enter the atomizing mist storage chamber.

[0009] Preferably, an oxygen inlet is provided below the first breathing piece, and the air inlet is parallel to the oxygen inlet, which facilitates the inhalation of the medicine mist along the direction of the airflow while oxygen inhalation is required during the atomization.

[0010] Preferably, the second respiratory piece is provided with an air outlet at the upper front portion of the atomizing mask, and a medicine mist storage cavity is provided in the second respiratory piece, and the medicine mist storage cavity includes the area between the second cushion and the air inlet, wherein the area on the side where the second cushion is located is the air outlet area, and the area on the side where the air inlet is located is the air inlet area.

[0011] Preferably, the area of the air outlet is 3% to 5% of the area of the tail end of the atomizing spacer.

[0012] Preferably, the central axis of the joint end passes through the air inlet area and the air inlet, and the central axis of the air inlet is arranged to be parallel and offset with the central axis of the joint end.

[0013] Preferably, the area of the radial cross section of the air outlet region is 10% to 20% of the area of the radial cross section of the air inlet region.

[0014] In summary, the medical mesh nebulizer medicine mist storage tank disclosed in the embodiment of the present invention provides a structural design that is different from the previous one by connecting the atomization mist storage chamber with the air inlet area and the oxygen inlet, thereby being suitable for the atomization medicine mist storage tank to develop a structure that can be used in different situations.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] When the user inhales, the air inlet valve diaphragm of the spacer is affected by the negative pressure in the spacer body and opens to the spacer, and air enters the spacer from the outside and flows into the spacer along with the medicine mist and enters the user's body. When the user exhales, the inlet valve diaphragm is in a closed state, ensuring that the medicine mist in the spacer tank does not overflow; the medical mesh nebulizer medicine mist spacer tank of the utility model is provided with an air inlet on the tail end, and the inlet one-way valve diaphragm is made of medical silicone material, which is easy to open and reset, and can reduce the patient's breath holding phenomenon due to lack of oxygen; the medical nebulizer medicine mist spacer tank of the utility model has an air inlet at the center position of the tail end, which forms an airflow with the center of the spacer tank as the axis, which can effectively carry away the mist particles on the inner wall, and can reduce the probability of the medicine adhering to the tank wall. Large particles can quickly form liquid due to their shorter flying distance, and fine atomized particles flow into the respiratory tract with the user's inhalation airflow, thereby improving the drug delivery rate and reducing side effects.

[0017] 2. In this utility model, the oxygen tube interface, located below the tail air inlet, of the medical net-type nebulizer's medicine mist storage tank is compatible with medical feeding equipment. Furthermore, the oxygen outlet airflow is arranged in the same direction as the air inlet. When the user requires oxygen atomization, this further enhances the central airflow, ensuring that more medicine mist is inhaled by the user, further improving the medicine mist delivery rate and enhancing the efficacy.

[0018] 3. The medical mesh nebulizer inhalation mask of this utility model features a silicone cushion where the mask body contacts the face. The cushion is integrally formed with the mask body or can be detachably fixed. Elastic band mounting plates are fixedly attached to each side of the mask body, ensuring a comfortable fit.

[0019] 4. In the present invention, the medical mesh nebulizer and its components can be connected to a ventilator circuit. The medicine mist storage tanks are connected to the ventilator circuits on both sides. When the medicine mist condenses in the storage tanks to form a mist liquid, the mist liquid can be temporarily stored in the storage tanks and will not enter the ventilator circuits and affect the operation of the ventilator. Furthermore, the medicine mist produced by the mesh nebulizer is gentle and does not affect the airflow of the ventilator circuits, thereby further broadening the scope of application of the present invention.

[0020] 5. Because the tank body is cylindrical and the connection assembly gradually reduces the diameter of the mist outlet, the speed at which the drug mist enters the connected nebulizer inhalation mask (mouthpiece) decreases. This increases the patient's comfort while reducing the phenomenon of drug mist dispersing and adhering to the face, forming droplets. The mist outlet of this medical mesh nebulizer inhalation mask is designed with a conical surface. When the user exhales, the vast majority of the exhaled air is guided through the conical surface to the outlet slot, which is less likely to cause drug mist to disperse. The fixed diameter of the interface of the drug mist storage tank can be adapted to inhalation devices with different interface diameters, further expanding its scope of application.

[0036] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0038] Example 1, as Figure 1-14 As shown, the utility model provides a medical mesh nebulizer atomizing medicine mist storage tank, including an atomizing medicine mist storage tank 1, which is formed with an atomizing liquid medicine mist inlet 111 and an air inlet 112. The atomizing liquid medicine mist inlet 111 and the air inlet 112 are arranged at the tail of the atomizing medicine mist storage tank 1, and an oxygen access port 12 is provided below the air inlet 112. The shell and the front end of the atomizing medicine mist storage tank are jointly formed with an atomizing medicine mist storage chamber 15 connected to the atomizing liquid medicine mist inlet, the air inlet 112, the oxygen access port 12 and a plurality of perforations; the first breathing piece 2, the second breathing piece 3 and the third breathing piece 5 are also included. The first breathing piece 2 includes a joint end 13, an inlet silicone plug 121, and a mating end 21. The second breathing piece 3 includes a breathing port 32, a first soft cushion 33, a second soft cushion 34, an air outlet 36 and a mounting plate 37; and the atomizing device 4 is also included.

[0039] The following describes the specific settings and functions.

[0040] like Figure 1 and Figure 4 As shown, the air inlet 112 is located at the center of the air inlet member, and the area of the air inlet 112 accounts for 20% to 30% of the area of the tail end of the atomizing mist storage tank 1. The first respiratory member 2 also includes an air inlet valve plate 14, which is installed in the atomizing mist storage chamber 15 and is located corresponding to the air inlet 112. The air inlet valve plate 14 is used to supply airflow into the atomizing mist storage chamber 15. An oxygen access port 12 is provided below the first respiratory member 2, and the air inlet member and the oxygen access port 12 are parallel. Oxygen is required during atomization, and it is beneficial for the medicine mist to be inhaled along the direction of the airflow. The second respiratory member 3 is formed with an air outlet 36 on the front upper part of the atomizing mask. The second breathing piece 3 contains a medicine mist storage chamber 11, which includes the area between the second soft cushion 34 and the air inlet 112. The area on one side where the second soft cushion 34 is located is the air outlet area, and the area on the other side where the air inlet 112 is located is the air inlet area. The area of the air outlet 36 is 3% to 5% of the area of the tail end of the atomizing storage tank 1. The central axis of the joint end 13 passes through the air inlet area and the air inlet 112. The central axis of the air inlet 112 is parallel to the central axis of the joint end 13 and is offset. The area of the radial cross-section of the air outlet area is 10% to 20% of the area of the radial cross-section of the air inlet area.

[0041] like Figure 1 and Figure 2 As shown, this embodiment discloses a mesh-type nebulizer atomized medicine mist storage tank 1, which can be detachably mounted to an atomizing device 4, allowing the atomizing device 4 to discharge atomized medicine mist (e.g., medicine mist with a particle size between 3 and 5 microns) into the atomizing tank 1, allowing the user to inhale the medicine mist in the atomizing tank 1 into the body. The ratio of the medicine mist inhaled by the user to the medicine mist discharged by the atomizing device 4 is defined as the medicine mist absorption rate. However, the atomizing tank 1 of this embodiment is not limited to use with the atomizing device 4; for example, the atomizing tank 1 can also be used (e.g., sold) alone.

[0042] Among them, such as Figure 3 As shown, the atomizer spacer 1 includes an air inlet 112 and an oxygen inlet 12, which are detachably connected to the respiratory components 2 and 3. While the air inlet 112 in this embodiment is illustrated as being used in conjunction with the respiratory components 2 and 3, the present invention is not limited thereto. For example, in other embodiments of the present invention, the air inlet 2 can also be used alone (e.g., sold) or in conjunction with other components.

[0043] like Figure 4 and Figure 5As shown, the air inlet component 112 of the spacer 1 in this embodiment includes a housing, an air inlet valve plate 14, and an oxygen inlet 12 below, including a silicone plug 121. The following describes the structure of each component of the spacer 1 and the connections between them, but the present invention is not limited thereto.

[0044] The atomized medicine mist storage tank 1 is formed with an atomized liquid medicine mist inlet 111, an air inlet 112 and a medicine mist storage chamber 11. The atomized liquid medicine mist inlet 111 and the air inlet 112 are circular holes in this embodiment, and a central axis A111 of the atomized liquid medicine mist inlet 111 is perpendicular to a central axis A112 of the air inlet 112 in this embodiment (e.g., Figure 2 ), but the present invention is not limited thereto. The atomized liquid medicine mist inlet 111 of the medicine mist storage tank 1 is used for detachably installing the atomizing device 4 .

[0045] Furthermore, the medicine mist storage tank 1 is located at the other side of the atomized liquid medicine mist inlet 111 and the air inlet 12 (e.g. Figure 3 or Figure 4 The left side of the connecting portion 13 is provided with a connecting end portion 13. In this embodiment, the connecting end portion 13 is annular, and a central axis A13 of the connecting end portion 13 is preferably symmetrically arranged with the central axis A112 of the air inlet 112 (e.g.: Figure 2 ). Wherein, the joint end 13 surrounds the component 2 (such as: Figure 2 、 Figure 3 ) forms an air inlet area and cavity area equal to the combined area of the above-mentioned aerosol storage tank 1 and assembly 2. However, to ensure sufficient storage space for the aerosolized aerosol in this embodiment and to reduce the aerosol discharge speed and increase the user's inhalation comfort, the above-mentioned breathing component 2 has a buffer zone and a smaller aerosol outlet.

[0046] It should be noted that the spacer 1 in this embodiment is assembled from a single piece, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the spacer 1 may also be a single piece.

[0047] like Figures 4 to 6 As shown, the spacer tank 1 and the assembly 2 are jointly formed with a connection to the atomized liquid medicine mist inlet 111, the air inlet 112, and the assembly 2. In other words, the interior space of the atomized medicine mist chamber 1 of this embodiment is preferably connected to the space outside the atomized medicine mist storage chamber 1 only through the atomized liquid medicine mist inlet 111, the air inlet 112, and the assembly 2.

[0048] In this embodiment, the atomizing mist storage chamber 15 preferably has a capacity of 400 ml and is generally of a hollow truncated cylindrical structure (e.g., the truncated cylindrical structure refers to a structure obtained by cutting away a portion of a cylinder, with the cut surface of the cylinder being generally perpendicular to the central axis A111 of the atomized liquid medicine mist inlet 111). Furthermore, the atomized liquid medicine mist inlet 111 is located on the arcuate surface of the truncated cylindrical structure, while the air inlets 112 and 13 are generally located on opposite sides of the truncated cylindrical structure.

[0049] like Figures 4 to 5 The oxygen inlet 12 is parallel to the air inlet 14, and oxygen is absorbed during atomization, further increasing the delivery rate of the medicine mist and making the user more comfortable.

[0050] like Figures 7 to 11 The above describes the structure and coordination of the air inlet and outlet components 1 and 3 of this embodiment. The following describes the specific structure of this embodiment 3. To achieve a low atomized liquid mist discharge rate for the mesh atomizer 4 of this embodiment, the component 3 preferably employs air outlets 36 , and each air outlet A36 is preferably parallel to the aforementioned air inlet area A13 , but the present invention is not limited thereto.

[0051] Specifically, as shown in Figures (1, 8, 9, and 11), the component 3 can be connected to the component 2 and the component 1 respectively to form different atomization mode options.

[0052] Furthermore, if Figure 1 and Figure 3 As shown, the components 3, 2 and 1 are connected and combined. It should be noted that the components 1, 2 and 3 of this embodiment are combined to form a natural chamber. The components can form a drug mist in the atomizer 4 that can be inhaled by the user.

[0053] As described above, the aerosol storage tank 1 in this embodiment connects the aerosol storage chamber 15 to the component 3 to provide a structural design different from the conventional one. This allows the aerosol 4 of this embodiment to break away from the existing structure and develop a structure suitable for use in different situations (e.g., when the aerosol liquid aerosol discharge rate is less than 20% or the aerosol liquid aerosol absorption rate is a specific value).

[0054] like Figure 4 、 Figure 5 and Figure 6As shown, the air inlet check valve 14 is installed within the atomizing mist storage chamber 15 and is positioned corresponding to the air inlet 112. In this embodiment, the air inlet check valve 14 is used to allow air to enter the atomizing mist storage chamber 15. In other words, the air inlet check valve 14 of this embodiment seals the air inlet 112 and prevents air from flowing out of the atomizing mist storage chamber 15 through the air inlet 112 when the user exhales, thereby effectively reducing the discharge rate of the atomized liquid medicine mist from the mesh nebulizer 4.

[0055] The air outlet 36 is mounted on the upper side of the assembly 3 and corresponds to the exhaust port 36. The air inlet of the assembly 3 is designed with a cone to allow the atomized drug flow to enter the assembly 3. In other words, the cone separates the atomization airflow of the assembly 3 and the exhaled airflow during atomization, further effectively improving the absorption rate of the atomized liquid drug mist by the nebulizer 4.

[0056] The above is a description of the air inlet and outlet components of this embodiment, but its specific structure can be adjusted and changed according to design requirements. For example, in other embodiments not shown in this utility model, the air inlet and outlet components 1, 2, and 3 can also be omitted or replaced with other components according to design requirements.

[0057] like Figure 3 The respiratory component 2 includes a mating end portion 21, and the mating end portion 21 is located at one end of the respiratory component 2 in this embodiment (eg, Figure 3 The right end of the breathing piece 2 in the figure is formed with a breathing port 32 located away from the mating end 21. In this embodiment, the interior space enclosed by the breathing pieces 2 and 3 is preferably connected to the space outside the breathing piece 3 only through the breathing port 32 and the mating end 21, but the present invention is not limited thereto.

[0058] like Figures 12 to 14 The breathing piece 2 is combined with the breathing piece 5 and the mesh nebulizer 4 to form an atomization pipeline, which can be connected to the breathing machine pipeline assembly for atomization.

[0059] Its overall working principle is as follows: 1. The utility model provides an air inlet and outlet assembly of a nebulizer atomizing medicine mist storage tank that is different from the previous mesh nebulizer to expand its scope of application. This medical nebulizer storage tank 1 can be used in conjunction with a comfortable nebulizer mask by providing an air inlet valve. The user can inhale external air through the air inlet valve, and the nebulizer interface is provided between the air inlet 112 of the medicine storage tank and the inhalation device interface. When the user inhales, the medicine mist will enter the inhalation device along with the airflow, and the mist outlet of the nebulizer is inserted into the position of the nebulizer interface of the spacer, and then the inhalation device is plugged into the inhalation device interface of the spacer. After wearing the inhalation device, atomization begins, and the nebulizer atomizes the medicine liquid and sprays it into the cavity of the spacer. When the user inhales, the air inlet valve diaphragm of the spacer is affected by the negative pressure in the spacer body to open towards the spacer, and air enters the spacer from the outside and flows into the inhalation device together with the medicine mist, and enters the user's body. When the user exhales, the air inlet valve diaphragm is in a closed state, ensuring that the medicine mist in the spacer tank does not overflow; the medical mesh nebulizer medicine mist spacer of the present invention is provided with an air inlet port 112 on the tail end, and the air inlet one-way valve diaphragm is made of medical silicone material, which is easy to open and reset, and can reduce the patient's breath holding phenomenon due to lack of oxygen; the medical nebulizer medicine mist spacer of the present invention is provided with an air inlet port 112 at the center position of the tail end, which forms an airflow with the center of the spacer tank as the axis, which can effectively carry away the mist particles on the inner wall, and can reduce the probability of the medicine adhering to the tank wall. Large particles can quickly form liquid due to their shorter flying distance, and fine atomized particles flow into the respiratory tract with the user's inhalation airflow, thereby improving the drug delivery rate and reducing side effects.

[0060] 2. In this utility model, the medical mesh nebulizer's drug mist storage tank is equipped with an oxygen tube interface located below the tail air inlet 112, allowing it to be used with medical feeding equipment. Furthermore, the oxygen outlet airflow is arranged in the same direction as the air inlet 112. When the user requires oxygen atomization, this can further enhance the central airflow, ensuring that more drug mist is inhaled by the user, further improving the drug mist delivery rate and enhancing the therapeutic effect.

[0061] 3. The medical mesh nebulizer inhalation mask of this utility model is equipped with a silicone cushion where it contacts the face. The cushion is integrally formed with the inhalation mask body or is detachably fixed. Elastic band mounting plates 37 are fixedly connected to each side of the inhalation mask body, ensuring a comfortable fit.

[0062] 4. In the present invention, the medical mesh nebulizer and its components can be connected to a ventilator circuit. The medicine mist storage tanks are connected to the ventilator circuits on both sides. When the medicine mist condenses in the storage tanks to form a mist liquid, the mist liquid can be temporarily stored in the storage tanks and will not enter the ventilator circuits and affect the operation of the ventilator. Furthermore, the medicine mist produced by the mesh nebulizer is gentle and does not affect the airflow of the ventilator circuits, thereby further broadening the scope of application of the present invention.

[0063] 5. Because the tank body is cylindrical and the connection assembly gradually reduces the diameter of the mist outlet, the speed at which the drug mist enters the connected nebulizer inhalation mask (mouthpiece) decreases. This increases the patient's comfort while reducing the phenomenon of drug mist diffused within the nebulizer inhalation mask and forming droplets on the face. The mist outlet of the medical mesh nebulizer inhalation mask of this utility model is designed with a conical surface. When the user exhales, the vast majority of the exhaled gas is guided by the conical surface to the outlet slot, which is less likely to cause the drug mist to diffuse. The fixed diameter of the interface of the drug mist storage tank can be adapted to inhalation devices with different interface diameters, further expanding its scope of application.

[0064] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
