Description

Technical Field

[0001] This application belongs to the technical field of medical devices, specifically relating to an atomizing face mask. Background Technology

[0002] A nebulizer mask is a medical device used for nebulized inhalation therapy. It needs to be connected to a nebulizer cup to help patients inhale medication in the form of an aerosol into their respiratory tract. It is mainly suitable for the treatment of respiratory diseases such as asthma, chronic obstructive pulmonary disease, and bronchitis.

[0003] Currently, nebulizer masks typically consist of a rigid component and a flexible component. The rigid component is more rigid than the flexible component. One end of the rigid component has a connecting port for connecting to the nebulizer cup, and the other end has an air outlet for accommodating the patient's mouth and nose. The flexible component is located at the air outlet and extends circumferentially around it. When a patient uses the nebulizer mask, the flexible component presses against the patient's face, allowing the rigid component to cover the patient's mouth and nose. A headband is used to secure the nebulizer mask to the patient's face. Because the rigid component is more rigid than the flexible component, it can apply pressure towards the patient's face under the action of the headband. This causes the flexible component to deform under the combined action of the rigid component and the patient's face, thus achieving a seal between the nebulizer mask and the patient's face.

[0004] However, because the flexible component extends circumferentially along the air outlet, its deformation capacity is relatively small. However, different patients have different nasal contours, which may prevent the flexible component from fully contacting the patient's nose. This affects the seal between the atomizing mask and the patient's face. In order to ensure the seal between the atomizing mask and the patient's face, a large pulling force is usually applied to the atomizing mask using a headband to increase the pressure between the flexible component and the patient's face. Although this method can increase the seal between the atomizing mask and the patient's face to a certain extent, it can also cause pressure marks on the patient's face, thus affecting the patient's wearing comfort. Utility Model Content

[0005] This application provides an atomizing mask to increase the seal between the atomizing mask and the patient's face and improve the patient's wearing comfort.

[0006] The technical solution adopted in this application is as follows:

[0007] A nebulizing mask, the nebulizing mask being connected to a nebulizing cup to deliver the aerosol generated by the nebulizing cup to the patient's airway inlet, the nebulizing mask comprising:

[0008] A sealing member having a fitting end for fitting a patient’s face and a supporting end opposite to the fitting end, the fitting end being provided with a receiving opening capable of simultaneously accommodating the patient’s mouth and nose, and the supporting end being provided with a protrusion capable of covering at least a portion of the patient’s nose and an installation opening located below the protrusion.

[0009] A support member is provided at the mounting port and is joined with the sealing member to form a delivery cavity. The support member is provided with a connection hole for connecting the atomizing cup. The connection hole is connected to the delivery cavity. The rigidity of the support member is greater than that of the sealing member.

[0010] By adopting the above technical solution, when using the nebulizer mask in this application, the nebulizer cup is connected to the connection hole so that the nebulizer cup is connected to the delivery chamber. Then, the nebulizer mask is worn on the patient's face using a headband so that the sealing end of the sealing member contacts the patient's face, and the patient's mouth and nose are simultaneously located in the receiving mouth, so that the aerosol generated in the nebulizer cup flows through the delivery chamber to the patient's airway inlet for inhalation therapy.

[0011] Because the rigidity of the support component is greater than that of the sealing component, the sealing component is more flexible than the support component, thereby increasing the comfort of the patient wearing the nebulizer mask. Simultaneously, since the support component is located at the mounting opening, which is below the protrusion, and the protrusion covers at least part of the patient's nose, the support component can avoid contact with the protrusion. This allows the portion of the sealing component corresponding to the patient's nose area to deform more significantly, increasing the sealing component's deformability. This allows the sealing component to adapt to various nasal contours, increasing the seal between the nebulizer mask and the patient's face, thus ensuring the effectiveness of the nebulizer treatment. Furthermore, because the portion of the sealing component corresponding to the patient's nose area can deform more significantly, it avoids the need for the headband to apply excessive tension to the nebulizer mask to maintain a seal with the patient's face. This reduces the pressure between the nebulizer mask and the patient's face, thus preventing pressure marks on the patient's face and greatly improving the comfort of wearing the nebulizer mask.

[0012] Optionally, the sealing member includes a fitting section extending circumferentially along the receiving port and a support section extending circumferentially along the mounting port, wherein the thickness of the support section is greater than the thickness of the fitting section.

[0013] By adopting the above technical solution, since the thickness of the support section is greater than the thickness of the fitting section, and the fitting section extends circumferentially along the receiving opening while the support section extends circumferentially along the mounting opening, the fitting end used to fit the patient's face becomes more flexible, making it easier to deform. This improves the patient's wearing experience and allows the fitting end to better conform to the patient's facial skin, enabling the atomizing mask to fit a wider range of nasal contours, further increasing the flexibility of the atomizing mask and improving the seal between the atomizing mask and the patient's face. Furthermore, because the thickness of the support section is greater than the thickness of the fitting end, the support end of the sealing member also possesses a certain rigidity to maintain the shape of the sealing member. The support end also disperses and reduces the pressure exerted by the support member on the sealing member, further reducing the pressure between the fitting end and the patient's face, thereby further improving the patient's wearing comfort.

[0014] Optionally, the inner side of the fitting section is provided with an edge, the edge being located at the receiving opening and extending circumferentially along the receiving opening, and the thickness of the edge being less than the thickness of the support section.

[0015] By adopting the above technical solution, since the inner side of the fitting section is provided with an edge, which is located at the receiving opening and extends circumferentially along the receiving opening, the edge can increase the structural strength of the fitting section at the receiving opening, thereby ensuring the shape of the receiving opening and avoiding possible tearing or other damage to the fitting section at the receiving opening, thus ensuring the seal between the atomizing mask and the patient's face. Since the thickness of the edge is less than the thickness of the support section, the structural strength of the fitting section at the receiving opening is ensured, and the fitting section at the receiving opening is also more prone to deformation than the support section, thus avoiding the situation where the fitting section is difficult to deform due to the presence of the edge.

[0016] Optionally, the thickness D1 of the support segment satisfies: 1mm≤D1≤3mm; and / or, the thickness D2 of the bonding segment satisfies: 0.3mm≤D2≤0.7mm.

[0017] By adopting the above technical solution, since the thickness D1 of the support segment satisfies: 1mm≤D1≤3mm, on the one hand, the support segment can have a certain strength so that the support segment can maintain the shape of the sealing component, and on the other hand, it can also ensure that when the support component applies pressure to the sealing component, the support segment can disperse and reduce the pressure, so as to ensure the patient's wearing comfort.

[0018] Since the thickness D2 of the bonding section satisfies: 0.3mm≤D2≤0.7mm, the deformation capacity of the bonding section can be guaranteed, so that the bonding section can fit the patient's face better, thereby increasing the patient's wearing comfort and the seal between the atomizing mask and the patient's face.

[0019] Optionally, one of the mounting port wall and the supporting member is provided with a connecting groove, and the other is provided with a connecting rib extending into the connecting groove.

[0020] By adopting the above technical solution, since one of the installation port wall and the support member is provided with a connecting groove, and the other of the two is provided with a connecting rib extending into the connecting groove, after the sealing member and the support member are assembled together, the connecting rib is located in the connecting groove, which increases the sealing performance between the sealing member and the support member on the one hand, and increases the connection stability between the two on the other hand.

[0021] Optionally, the connecting rib is provided with a fixing hole, and the groove wall of the connecting groove is provided with a fixing post extending into the fixing hole.

[0022] By adopting the above technical solution, since the connecting rib is provided with fixing holes and the groove wall of the connecting groove is provided with fixing posts that extend into the fixing holes, the sealing component and the supporting component are fixedly connected, thereby increasing the connection stability of the two. At the same time, the fixing holes and fixing posts can be hidden in the connecting groove, which on the one hand makes the external contour of the atomizing mask more regular, thereby improving the appearance quality of the atomizing mask, and on the other hand avoids the situation where the structure used to fix the sealing component and the supporting component is exposed on the outside of the atomizing mask and is prone to dirt accumulation, thus ensuring the cleanliness of the atomizing mask and reducing the difficulty of cleaning the atomizing mask.

[0023] Optionally, one of the sidewalls of the connecting groove and the sidewall of the connecting rib is provided with a limiting groove, and the other of the two is provided with a limiting rib extending into the limiting groove.

[0024] By adopting the above technical solution, since one of the sidewalls of the connecting groove and the sidewall of the connecting rib is provided with a limiting groove, and the other is provided with a limiting rib extending into the limiting groove, the cooperation between the limiting rib and the limiting groove can be used to stop the sealing member and the supporting member in the direction of their separation, thereby increasing the connection stability between the sealing member and the supporting member. At the same time, it also increases the connection area between the sealing member and the supporting member, thereby further increasing the connection stability and sealing performance between the two. Furthermore, it can make the sealing path between the sealing member and the supporting member more tortuous, thereby further improving the sealing performance between them.

[0025] Optionally, the support member is provided with an exhaust hole, and the atomizing mask further includes a valve plate disposed at the exhaust hole. The valve plate is movable relative to the support member so that the valve plate has an open position that fully opens the exhaust hole and a closed position that partially blocks the exhaust hole. When the valve plate is in the closed position, an air leakage channel is formed between the outer periphery of the valve plate and the hole wall of the exhaust hole.

[0026] By adopting the above technical solution, when a patient wearing the nebulizing mask of this application exhales, the valve plate is in the closed position, which blocks part of the exhaust port. This allows the aerosol in the delivery chamber to enter the patient's respiratory tract during inhalation. During exhalation, the valve plate moves from the closed position to the open position, fully opening the exhaust port and allowing the exhaled air to exit the delivery chamber through the exhaust port. Because a venting channel is formed between the outer periphery of the valve plate and the wall of the exhaust port when the valve plate is in the closed position, outside air can enter the delivery chamber through this venting channel during inhalation, reducing the feeling of shortness of breath and further improving patient comfort.

[0027] Optionally, the valve plate includes a snap-fit ​​portion, a blocking portion, and a thin-walled portion disposed between the snap-fit ​​portion and the blocking portion. The snap-fit ​​portion snaps onto the support member. When the valve plate is in the open position, the thin-walled portion undergoes elastic deformation to apply a force to the blocking portion toward the closed position.

[0028] By adopting the above technical solution, since the snap-fit ​​part snaps into the support member, the valve plate is connected to the support member by snap-fit. On the one hand, this increases the connection stability between the valve plate and the support member, and on the other hand, it reduces the assembly difficulty of the valve plate, thereby improving the production efficiency of the nebulizer mask. When the valve plate is in the open position, the thin-walled part undergoes elastic deformation and applies a force to the sealing part towards the closed position. As a result, when the patient exhales, the sealing part can move towards the closed position under the action of the thin-walled part, thereby enabling the sealing part to automatically close the exhaust port.

[0029] Optionally, the outer periphery of the sealing portion has a connecting section and a clearance section. The connecting section is connected to the thin-walled portion. When the valve plate is in the closed position, the clearance section and the wall of the exhaust port form the venting channel, and the flow area S of the venting channel satisfies: 5mm. 2 ≤S≤50mm 2 .

[0030] By adopting the above technical solution, the area S of the venting channel satisfies: 5mm. 2 ≤S≤50mm 2This reduces the feeling of breathlessness experienced by patients during inhalation, thus improving their experience. It also ensures that more aerosol enters the patient's respiratory tract during inhalation, thereby maximizing the effectiveness of nebulization therapy.

[0031] Optionally, the outer wall of the support member is flush with and fits the outer wall of the sealing member;

[0032] And / or, the protrusion is provided in a shape-conforming fit to the bridge of the nose.

[0033] By adopting the above technical solution, since the outer wall of the supporting component is flush with the outer wall of the sealing component, the appearance quality of the atomizing mask is improved on the one hand, and the tactile feel for the patient is improved on the other hand, thereby improving the patient's user experience. In addition, it avoids the situation where dirt and grime can easily accumulate due to the step between the sealing component and the supporting component, thus ensuring the cleanliness of the atomizing mask and making it easier for the patient to clean the atomizing mask.

[0034] Because the protrusion is designed to fit the shape of the bridge of the nose, it can better accommodate the patient's nose, and the sealing component can better deform according to the contour of the patient's nose to ensure the fit between the sealing component and the patient's nose, thereby ensuring the seal between the atomizing mask and the patient.

[0035] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0036] 1. The atomizing mask of this application includes a sealing member and a supporting member. The rigidity of the supporting member is greater than that of the sealing member. The sealing member has a fitting end for conforming to the patient's face and a supporting end opposite to the fitting end. The fitting end is provided with an accommodating opening capable of simultaneously accommodating the patient's mouth and nose. The supporting end is provided with a protrusion capable of covering at least a portion of the patient's nose and an installation opening located below the protrusion. The supporting member is located at the installation opening and is joined with the sealing member to form a delivery cavity, thereby allowing the supporting member to avoid the protrusion, so that the portion of the sealing member corresponding to the patient's nasal area can undergo greater deformation to increase the sealing effect. The deformable nature of the sealing component allows it to adapt to the nasal contours of various patients, increasing the seal between the nebulizer mask and the patient's face, thereby ensuring the effectiveness of nebulizer treatment. Furthermore, because the portion of the sealing component corresponding to the patient's nasal area can deform significantly, it avoids the need for the headband to apply considerable tension to the nebulizer mask to maintain a proper seal. This reduces the pressure between the nebulizer mask and the patient's face, thus minimizing the risk of pressure marks and greatly improving the patient's comfort when wearing the nebulizer mask.

[0037] 2. The sealing component in this application includes a fitting section extending circumferentially along the receiving opening and a support section extending circumferentially along the mounting opening. The thickness of the support section is greater than the thickness of the fitting section, which makes the fitting end used to fit the patient's face more flexible, so that the fitting end is more easily deformable. On the one hand, this can improve the patient's wearing experience, and on the other hand, it can make the fitting end fit the patient's facial skin better, so that the atomizing mask can adapt to more patients' nasal contours, further increasing the flexibility of the atomizing mask and further improving the seal between the atomizing mask and the patient's face.

[0038] 3. The inner side of the fitting section in this application is provided with an edge, which is located at the receiving opening and extends circumferentially along the receiving opening. This edge increases the structural strength of the fitting section at the receiving opening to ensure the shape of the receiving opening and prevent the fitting section at the receiving opening from tearing or other damage, thereby ensuring the seal between the atomizing mask and the patient's face. The thickness of the edge is less than the thickness of the support section, which ensures the structural strength of the fitting section at the receiving opening and makes the fitting section at the receiving opening more easily deformable than the support section, thus avoiding the situation where the fitting section is difficult to deform due to the presence of the edge.

Detailed Implementation

[0054] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0055] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0058] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0059] Reference Figures 1 to 12 A nebulizing mask is disclosed. The nebulizing mask is used to connect to a nebulizing cup to deliver the aerosol generated by the nebulizing cup to the patient's airway inlet. The nebulizing mask includes a sealing member 1 and a supporting member 2. The sealing member 1 has a fitting end for fitting the patient's face and a supporting end opposite to the fitting end. The fitting end is provided with a receiving opening 11 that can simultaneously accommodate the patient's mouth and nose. The supporting end is provided with a protrusion 12 that can cover at least a part of the patient's nose and an installation opening 13 located below the protrusion 12. The supporting member 2 is located at the installation opening 13 and is spliced ​​with the sealing member 1 to form a delivery cavity. The supporting member 2 is provided with a connecting hole 21 for connecting the nebulizing cup. The connecting hole 21 is connected to the delivery cavity. The rigidity of the supporting member 2 is greater than that of the sealing member 1.

[0060] It is understandable that the sealing member 1 is elastic, so that the sealing member 1 can deform.

[0061] It should be noted that the sealing member 1 mentioned above has a fitting end for fitting the patient's face, which means that after the atomizing mask is worn on the patient's face, the fitting end abuts against the patient's face; the protrusion 12 mentioned above can cover at least a part of the patient's nose, which means that after the atomizing mask is worn on the patient's face, the projection of the protrusion 12 toward the patient's face covers at least a part of the patient's nose.

[0062] When using the nebulizer mask of this application, the nebulizer cup is connected to the connection hole 21 so that the nebulizer cup is connected to the delivery chamber. Then, the nebulizer mask is worn on the patient's face using the headband so that the fitting end of the sealing member 1 is in contact with the patient's face, and the patient's mouth and nose are simultaneously located in the receiving port 11, so that the aerosol generated in the nebulizer cup flows through the delivery chamber to the patient's airway inlet for inhalation therapy.

[0063] Because the rigidity of the support member 2 is greater than that of the sealing member 1, the sealing member 1 is more flexible than the support member 2, thereby increasing the comfort of the patient wearing the nebulizer mask. At the same time, since the support member 2 is located at the mounting port 13, which is below the protrusion 12, the protrusion 12 can cover at least part of the patient's nose. This allows the support member 2 to avoid the protrusion 12, so that the part of the sealing member 1 corresponding to the patient's nose area can undergo greater deformation, thereby increasing the deformation capacity of the sealing member 1. This allows the sealing member 1 to adapt to the nasal contours of various patients, thereby increasing the seal between the nebulizer mask and the patient's face, and thus ensuring the nebulizer treatment effect for the patient.

[0064] In addition, since the part of the sealing component 1 corresponding to the patient's nasal area can undergo large deformation, it avoids the need to apply a large pulling force to the atomizing mask with the headband to ensure the seal between the atomizing mask and the patient's face. This reduces the pressure between the atomizing mask and the patient's face, and to a certain extent avoids the occurrence of pressure marks on the patient's face, thus greatly improving the patient's comfort when wearing the atomizing mask.

[0065] Furthermore, because the sealing component 1 can undergo significant deformation, the nebulizer mask can be adapted to various patients, thereby increasing the seal between the nebulizer mask and the patient's face. This avoids eye irritation caused by gaps between the nebulizer mask and the patient's nose, improving patient comfort during nebulizer treatment and enhancing the user experience. It also prevents drug waste, allowing more drug aerosol to be inhaled into the respiratory tract, thus improving the effectiveness of nebulizer treatment.

[0066] This application does not specifically limit the materials used to manufacture the sealing member 1 and the supporting member 2. Preferably, the sealing member 1 is made of silicone to ensure its flexibility and deformability, thereby improving the patient's wearing experience. The sealing member 1 can also be made transparent to improve the visibility of the nebulization treatment. The supporting member 2 is made of polyvinyl chloride to ensure its rigidity, thus maintaining the shape of the nebulization mask. The supporting member 2 can also be made transparent to improve the visibility of the nebulization treatment. Of course, in other embodiments, the sealing member 1 can also be made of other materials with lower rigidity than the supporting member 2, such as rubber; the supporting member 2 can also be made of other hard plastic materials, such as polypropylene.

[0067] This application does not specifically limit the structure of the sealing member 1; preferably, refer to... Figures 4 to 9 The sealing member 1 includes a fitting section 14 extending circumferentially along the receiving port 11 and a support section 15 extending circumferentially along the mounting port 13, wherein the thickness of the support section 15 is greater than the thickness of the fitting section 14.

[0068] Because the thickness of the support section 15 is greater than that of the fitting section 14, and the fitting section 14 extends circumferentially along the receiving opening 11 while the support section 15 extends circumferentially along the mounting opening 13, the fitting end used to fit the patient's face is made softer, making it easier for the fitting end to deform. This improves the patient's wearing experience and allows the fitting end to fit the patient's facial skin more closely, enabling the atomizing mask to adapt to more patients' nasal contours, further increasing the flexibility of the atomizing mask and further improving the seal between the atomizing mask and the patient's face.

[0069] In addition, since the thickness of the support section 15 is greater than the thickness of the fitting end, the support end of the sealing member 1 can also have a certain rigidity to maintain the shape of the sealing member 1, and the support end can also disperse and reduce the pressure applied by the support member 2 to the sealing member 1, so as to further reduce the pressure between the fitting end and the patient's face, thereby further improving the patient's wearing comfort.

[0070] The better one is to refer to Figures 4 to 9 The fitting section 14 includes a first section 141 located at the patient's bridge of the nose, a second section 142 located below the patient's mouth, and a third section 143 located on both sides of the patient's nose and mouth. The width of the first section 141 is greater than the width of the second section 142, and the width of the second section 142 is greater than the width of the third section 143, so that the sealing member 1 can undergo greater deformation below the patient's mouth and nose, so that the atomizing mask can be used by different patients, thereby increasing the flexibility of the atomizing mask and ensuring the seal between the atomizing mask and the patient's face.

[0071] It should be noted that the width of the first segment 141 mentioned above refers to the dimension of the first segment 141 along the outer contour of the sealing member 1 from the fitting end to the supporting end; the width of the second segment 142 mentioned above refers to the dimension of the second segment 142 along the outer contour of the sealing member 1 from the fitting end to the supporting end; and the width of the third segment 143 mentioned above refers to the dimension of the third segment 143 along the outer contour of the sealing member 1 from the fitting end to the supporting end.

[0072] It is understood that the support segment 15 has an upper segment corresponding to the first segment 141, a lower segment corresponding to the second segment 142, and a middle segment corresponding to the third segment 143. The width of the middle segment is greater than the width of the upper segment, and the width of the middle segment is greater than the width of the lower segment, so as to ensure that the support segment 15 maintains the shape of the sealing member 1.

[0073] Of course, in other embodiments, the width of the fitting segment 14 can also be set to remain constant along the circumference of the receiving opening 11.

[0074] Furthermore, refer to Figure 4 , Figure 5 and Figure 6 An edge 144 is provided on the inner side of the fitting section 14. The edge 144 is located at the receiving opening 11 and extends circumferentially along the receiving opening 11. This edge 144 increases the structural strength of the fitting section 14 at the receiving opening 11, ensuring the shape of the receiving opening 11 and preventing potential tearing or damage to the fitting section 14 at the receiving opening 11. This, in turn, ensures a tight seal between the atomizing mask and the patient's face. The shape of the receiving opening 11 prevents the fitting section 14 at the receiving opening 11 from tearing or other damage, thereby ensuring the seal between the atomizing mask and the patient's face; the thickness of the edge 144 is less than the thickness of the support section 15, thereby ensuring the structural strength of the fitting section 14 at the receiving opening 11 and making the fitting section 14 at the receiving opening 11 more easily deformable than the support section 15, so as to avoid the situation where the fitting section 14 is difficult to deform due to the presence of the edge 144.

[0075] It should be noted that the inner side of the fitting section 14 refers to the side of the fitting section 14 that is away from the patient's face after the atomizing mask is worn on the patient's face; the thickness at the edge 144 mentioned above refers to the thickness of the fitting section 14 plus the thickness of the edge 144.

[0076] In a preferred embodiment, refer to Figure 5The thickness D1 of the support segment 15 satisfies: 1mm≤D1≤3mm. On the one hand, this ensures that the support segment has a certain strength so that it can maintain the shape of the sealing member 1. On the other hand, it also ensures that when the support member 2 applies pressure to the sealing member 1, the support segment 15 can disperse and reduce the pressure to ensure the patient's wearing comfort.

[0077] Of course, in other embodiments, the thickness D1 of the support segment 15 can be set to be greater than 3 mm or less than 1 mm.

[0078] In a preferred embodiment, refer to Figure 5 The thickness D2 of the fitting section 14 satisfies: 0.3mm≤D2≤0.7mm, which ensures the deformation capacity of the fitting section 14, so that the fitting section 14 can fit the patient's face better, thereby increasing the patient's wearing comfort and the seal between the atomizing mask and the patient's face.

[0079] Of course, in other embodiments, the thickness D2 of the bonding segment 14 can also be set to be greater than 0.7 mm or less than 0.3 mm.

[0080] In other embodiments, the sealing member 1 may also be a structure with a consistent thickness to reduce the manufacturing difficulty of the sealing member 1.

[0081] In a preferred embodiment, refer to Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The sealing member 1 and the support member 2 are provided with a connecting groove 131 on one of the walls of the installation port 13 and a connecting rib 22 extending into the connecting groove 131 on the other. That is, after the sealing member 1 and the support member 2 are assembled together, the connecting rib 22 is located in the connecting groove 131, which increases the sealing between the sealing member 1 and the support member 2 on the one hand, and increases the connection stability between the two on the other hand.

[0082] Specifically, the connecting groove 131 is provided on the wall of the mounting port 13, and the connecting rib 22 is provided on the edge of the supporting member 2. That is to say, the mounting port 13 of the sealing member 1 is wrapped around the outside of the connecting rib 22 to increase the connection stability between the sealing member 1 and the supporting member 2.

[0083] The better one is to refer to Figure 3 and Figure 9 The connecting groove 131 extends circumferentially along the mounting opening 13, and the connecting rib 22 extends circumferentially along the support member 2 to increase the mating area between the connecting rib 22 and the connecting groove 131, thereby further increasing the sealing performance between the sealing member 1 and the support member 2 and increasing the connection stability between the two.

[0084] This application does not specify the connection method between the sealing member 1 and the supporting member 2, which can be any of the following embodiments:

[0085] Example 1, in this example, refers to Figures 6 to 9 The connecting rib 22 is provided with a fixing hole 221, and the groove wall of the connecting groove 131 is provided with a fixing post 132 extending into the fixing hole 221, thereby realizing the fixed connection between the sealing member 1 and the supporting member 2, so as to increase the connection stability of the two; at the same time, the fixing hole 221 and the fixing post 132 can be hidden in the connecting groove 131, which on the one hand makes the outer contour of the atomizing mask more regular, thereby improving the appearance quality of the atomizing mask, and on the other hand avoids the structure used to fix the sealing member 1 and the supporting member 2 being exposed on the outside of the atomizing mask, which is prone to dirt accumulation, thus ensuring the cleanliness of the atomizing mask and reducing the difficulty of cleaning the atomizing mask.

[0086] Furthermore, refer to Figure 7 One of the side walls of the connecting groove 131 and the connecting rib 22 is provided with a limiting groove 133, and the other is provided with a limiting rib 222 extending into the limiting groove 133. The limiting rib 222 and the limiting groove 133 can be used to stop the sealing member 1 and the supporting member 2 in the direction of their separation, thereby increasing the connection stability between the sealing member 1 and the supporting member 2. At the same time, it also increases the connection area between the sealing member 1 and the supporting member 2, thereby further increasing the connection stability and sealing performance between the sealing member 1 and the supporting member 2. Furthermore, it can make the sealing path between the sealing member 1 and the supporting member 2 more tortuous, thereby further improving the sealing performance between them.

[0087] Specifically, the limiting groove 133 is provided on the side wall of the connecting groove 131, and the limiting rib 222 is provided on the side wall of the connecting rib 22, thereby enabling the limiting rib 222 to increase the structural strength of the connecting rib 22, so as to ensure the structural strength of the supporting member 2.

[0088] Preferably, the limiting groove 133 extends circumferentially along the mounting opening 13, and the limiting rib 222 extends circumferentially along the support member 2, so as to increase the connection area between the limiting rib 222 and the limiting groove 133, and further increase the connection stability between the sealing member 1 and the support member 2.

[0089] When producing the atomizing mask, the support component 2 is produced first, and then the produced support component 2 is placed into the mold. Liquid material for making the sealing component 1 is then poured into the mold so that the liquid material solidifies in the mold and forms the sealing component 1, while the fixing column 132 on the sealing component 1 is formed.

[0090] Example 2: In this example, the sealing component 1 and the supporting component 2 are integrally molded using a two-color injection molding process to achieve a fixed connection between the sealing component 1 and the supporting component 2, thereby increasing the connection stability between the sealing component 1 and the supporting component 2 and increasing the sealing performance between them.

[0091] Of course, in other embodiments, the sealing member 1 can also be fixedly connected to the support member 2 by means of adhesive or fasteners.

[0092] In a preferred embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 11 and Figure 12 The support member 2 is provided with an exhaust hole 23. The atomizing mask also includes a valve plate 3 located at the exhaust hole 23. The valve plate 3 can move relative to the support member 2 so that the valve plate 3 has an open position that fully opens the exhaust hole 23 and a closed position that partially blocks the exhaust hole 23. When the valve plate 3 is in the closed position, an air leakage channel 34 is formed between the outer periphery of the valve plate 3 and the hole wall of the exhaust hole 23.

[0093] When a patient wearing the nebulizer mask described in this application exhales, valve plate 3 is in the closed position, blocking a portion of the exhaust port 23. This allows the aerosol in the delivery chamber to enter the patient's respiratory tract during exhalation. During exhalation, valve plate 3 moves from the closed position to the open position, fully opening the exhaust port 23, allowing the exhaled air to exit the delivery chamber through the exhaust port 23. Since valve plate 3 is in the closed position, a venting channel 34 is formed between the outer periphery of valve plate 3 and the wall of the exhaust port 23. This allows outside air to enter the delivery chamber through the venting channel 34 during inhalation, reducing the feeling of shortness of breath and further improving patient comfort.

[0094] Specifically, refer to Figures 1 to 3 The valve plate 3 is located outside the support member 2, that is, the valve plate 3 is located outside the delivery chamber, so that when the valve plate 3 moves from the closed position to the open position, the valve plate 3 moves toward the side away from the support member 2, and when the valve plate 3 moves from the open position to the closed position, the valve plate 3 moves toward the side of the support member 2, so that the valve plate 3 can avoid the patient's face, so as to ensure the normal movement of the valve plate 3 between the open position and the closed position.

[0095] This application does not specifically limit the structure of valve plate 3; preferably, refer to... Figure 12The valve plate 3 includes a snap-fit ​​portion 31, a blocking portion 32, and a thin-walled portion 33 disposed between the snap-fit ​​portion 31 and the blocking portion 32. The snap-fit ​​portion 31 is snapped into the support member 2. When the valve plate 3 is in the open position, the thin-walled portion 33 undergoes elastic deformation to apply a force to the blocking portion 32 toward the closed position.

[0096] It is understandable that the valve plate 3 is made of plastic material, and the thickness of the thin-walled part 33 is less than the thickness of the snap-fit ​​part 31 and the thickness of the sealing part 32, so that the thin-walled part 33 can undergo elastic deformation more easily than the sealing part 32 and the snap-fit ​​part 31.

[0097] Since the snap-fit ​​part 31 snaps into the support member 2, the valve plate 3 is connected to the support member 2 by snap-fit. This increases the connection stability between the valve plate 3 and the support member 2 and reduces the assembly difficulty of the valve plate 3, thereby improving the production efficiency of the nebulizer mask. When the valve plate 3 is in the open position, the thin-walled part 33 undergoes elastic deformation and applies a force to the sealing part 32 toward the closed position. As a result, when the patient exhales, the sealing part 32 can move toward the closed position under the action of the thin-walled part 33, thereby enabling the sealing part 32 to automatically close the exhaust port 23.

[0098] Preferably, both the snap-fit ​​part 31 and the sealing part 32 are sheet-like structures, and the thin-walled part 33 is a ribbed structure, so as to reduce the weight of the valve plate 3 and enable the sealing part 32 to move toward the open position under the action of the patient's exhalation.

[0099] Specifically, refer to Figure 12 The snap-fit ​​part 31 has a snap-fit ​​protrusion 311, and the support member 2 is provided with a snap-fit ​​hole 24. The snap-fit ​​protrusion 311 and the snap-fit ​​hole 24 are snap-fitted together to realize the snap-fit ​​engagement between the snap-fit ​​part 31 and the support member 2.

[0100] Furthermore, refer to Figure 10 and Figure 11 A stop rib 231 is provided in the exhaust hole 23. When the valve plate 3 is in the closed position, the valve plate 3 abuts against the stop rib 231 so that the stop rib 231 limits the valve plate 3 to prevent the valve plate 3 from moving excessively into the support member 2, so as to ensure the sealing effect of the valve plate 3 on the exhaust hole 23.

[0101] Furthermore, the outer periphery of the sealing part 32 has a connecting section and a clearance section. The connecting section is connected to the thin-walled part 33. When the valve plate 3 is in the closed position, a venting channel 34 is formed between the clearance section and the wall of the exhaust port 23, and the flow area S of the venting channel 34 satisfies: 5mm 2 ≤S≤50mm 2This reduces the feeling of breathlessness experienced by patients during inhalation, thus improving their experience. It also ensures that more aerosol enters the patient's respiratory tract during inhalation, thereby maximizing the effectiveness of nebulization therapy.

[0102] In other embodiments, the gap between the valve plate 3 and the wall of the exhaust port 23 can be eliminated, and a hole structure can be provided on the valve plate 3. That is, the gap between the valve plate 3 and the wall of the exhaust port 23 can be replaced by a hole structure provided on the valve plate 3, so that when the patient inhales, the outside air can enter the delivery chamber through the hole structure on the valve plate 3, which can also reduce the patient's feeling of shortness of breath.

[0103] In other embodiments, the valve plate 3 includes a plate body, a movable column disposed on the plate body, and a spring disposed on the movable column. The movable column passes through the support member 2, and the spring acts on the support member 2 and applies an elastic force to the plate body to move toward the closed position. Thus, when the patient exhales, the exhaled gas exerts a force on the valve plate 3 to move toward the open position, so that the plate body overcomes the elastic force of the spring and moves toward the open position. When the patient inhales, the valve plate 3 moves toward the closed position under the action of the spring.

[0104] This application does not specifically limit the positions of the vent hole 23 and the connection hole 21. Preferably, refer to Figures 1 to 3 The exhaust port 23 is located below the connecting hole 21. This allows the valve plate 3 to avoid contact with the atomizing cup, ensuring the normal movement of the valve plate 3, and also improves the appearance of the atomizing mask. In other embodiments, the exhaust port 23 may also be located above or to the side of the connecting hole 21.

[0105] In a preferred embodiment, refer to Figures 1 to 3 The outer wall of the support member 2 is flush with the outer wall of the sealing member 1, meaning that the connection between the support member 2 and the sealing member 1 is a smooth transition. This improves the appearance of the atomizing mask and enhances the tactile feel for the patient, thus improving the user experience. It also prevents dirt and grime from accumulating due to the step between the sealing member 1 and the support member 2, ensuring the cleanliness of the atomizing mask and facilitating cleaning by the patient.

[0106] In a preferred embodiment, refer to Figures 1 to 3 The protrusion 12 is designed to fit the shape of the bridge of the nose. In other words, the protrusion 12 is designed to mimic the bridge of the nose, so that the protrusion 12 can better accommodate the patient's nose, and the sealing component can better deform according to the contour of the patient's nose to ensure the fit between the sealing component 1 and the patient's nose, thereby ensuring the seal between the atomizing mask and the patient.

[0107] It should be noted that the aforementioned protrusion 12 corresponding to the nose bridge contour fitting setting means that the protrusion 12 is set from bottom to top towards the fitting end, and the two sides of the protrusion 12 are set towards the fitting end in a direction that moves away from each other.

[0108] In a preferred embodiment, refer to Figure 10 and Figure 11 The support member 2 has extension plates 25 on both sides. Each extension plate 25 has at least two headband holes 251. That is, when connecting the headband to the atomizing mask, one end of the headband is first passed through one of the headband holes 251, and then the headband is folded back and passed through the other headband hole 251 to increase the connection stability between the headband and the atomizing mask. After the atomizing mask is worn on the patient's face, the two extensions are located on the left and right sides of the patient's face, so that the atomizing mask can be worn on the patient's face using the headband.

[0109] Specifically, each extension plate 25 is provided with two headband holes 251 to ensure the stability of the connection between the headband and the support member 2 while reducing the difficulty of installing the headband.

[0110] In a preferred embodiment, refer to Figure 10 and Figure 11 The connecting hole 21 is a stepped hole, with the smaller end of the stepped hole located on the side of the support member 2 close to the sealing member 1, thereby enabling the atomizing mask in this application to connect to different models of atomizing cups, thereby increasing the flexibility of the atomizing mask.
