Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to an atomizing mask. Background Art

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

[0003] At present, the atomizing mask generally includes a rigid component and a flexible component. The rigidity of the rigid component is greater than that of the flexible component. One end of the rigid component has a connecting port for connecting to the atomizing cup, and the other end of the rigid component has an air outlet capable of accommodating the patient's mouth and nose. The flexible component is arranged at the air outlet and extends around the circumference of the air outlet. When the patient uses the atomizing mask, the flexible component contacts the patient's face so that the rigid component cover is arranged outside the patient's mouth and nose, and the atomizing mask is fixed to the patient's face using a headband. Since the rigidity of the rigid component is greater than that of the flexible component, the rigid component can apply pressure to the flexible component in the direction of the patient's face under the action of the headband, so that the flexible component is deformed under the action of the rigid component and the patient's face, thereby achieving a seal between the atomizing mask and the patient's face.

[0004] However, since the flexible component is extended along the circumference of the air outlet, the deformation capacity of the flexible component is relatively small. However, the contours of the noses of different patients are different, which may result in the flexible component being unable to fully contact the patient's nose, thereby affecting the sealing effect between the nebulizer mask and the patient's face. In order to ensure the sealing effect between the nebulizer mask and the patient's face, it is usually necessary to use a headband to apply a large pulling force to the nebulizer mask to increase the contact force between the flexible component and the patient's face. Although this method can increase the sealing between the nebulizer mask and the patient's face to a certain extent, it will also cause indentations on the patient's face, thereby affecting the patient's wearing comfort. Summary of the invention

[0005] The present application provides an atomizing mask to increase the sealing performance between the atomizing mask and the patient's face and improve the wearing comfort of the patient.

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

[0007] An atomizing mask, the atomizing mask is used to be connected to an atomizing cup to deliver the aerosol generated by the atomizing cup to the airway entrance of a patient, the atomizing mask comprising:

[0008] A sealing member, the sealing member having a fitting end for fitting the 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, the supporting end being provided with a raised portion capable of covering at least a partial area of ​​the patient's nose and a mounting opening located below the raised portion;

[0009] A support component is arranged at the installation port and is spliced ​​together with the sealing component to form a delivery cavity. The support component is provided with a connection hole for connecting the atomizer cup, and the connection hole is connected to the delivery cavity. The rigidity of the support component is greater than that of the sealing component.

[0010] By adopting the above technical solution, when using the nebulizer mask in the present application, the nebulizer cup is connected to the connecting hole so that the nebulizer cup is connected to the delivery chamber, and then the nebulizer mask is worn on the patient's face using a headband so that the fitting end of the sealing component contacts the patient's face, and the patient's mouth and nose are simultaneously located in the accommodating port, so that the aerosol generated in the nebulizer cup flows through the delivery chamber to the patient's airway entrance for inhalation treatment by the patient.

[0011] Since the rigidity of the supporting member is greater than that of the sealing member, the sealing member is softer than the supporting member, thereby increasing the comfort of the patient wearing the atomizing mask; at the same time, since the supporting member is arranged at the mounting port, the mounting port is located below the raised portion, and the raised portion can cover at least part of the patient's nose area, thereby enabling the supporting member to form an avoidance with the raised portion, so that the portion of the sealing member corresponding to the patient's nose area can undergo a large deformation, thereby increasing the deformation capacity of the sealing member, thereby enabling the sealing member to adapt to the nose contours of a variety of patients, thereby increasing the sealing between the atomizing mask and the patient's face, thereby ensuring the atomization treatment effect on the patient; in addition, since the portion of the sealing member corresponding to the patient's nose area can undergo a large deformation, thereby avoiding the need to use a headband to apply a large pulling force to the atomizing mask to ensure the sealing between the atomizing mask and the patient's face, thereby reducing the pressing force between the atomizing mask and the patient's face, thereby avoiding the situation where the patient's face is prone to indentation to a certain extent, thereby greatly improving the patient's comfort in wearing the atomizing mask.

[0012] Optionally, the sealing member includes a fitting segment extending along the circumference of the receiving opening and a supporting segment extending along the circumference of the mounting opening, and a thickness of the supporting segment is greater than a thickness of the fitting segment.

[0013] By adopting the above technical scheme, since the thickness of the supporting section is greater than the thickness of the fitting section, and the fitting section is extended along the circumference of the accommodating opening, and the supporting section is extended along the circumference of the mounting opening, the fitting end used to fit the patient's face is softer, so that the fitting end is easier to deform, which can improve the patient's wearing experience on the one hand, and can make the fitting end fit the patient's facial skin more closely on the other hand, so that the atomizing mask can be adapted to more patient's nasal contours, further increase the flexibility of the atomizing mask and further improve the sealing between the atomizing mask and the patient's face; in addition, since the thickness of the supporting section is greater than the thickness of the fitting end, the supporting end of the sealing member can have a certain rigidity to maintain the shape of the sealing member, and the supporting end can also disperse and reduce the pressure exerted by the supporting member on the sealing member, so as to further reduce the pressing force between the fitting end and the patient's face, thereby further improving the wearing comfort of the patient.

[0014] Optionally, an edge is provided on the inner side of the fitting section, the edge is located at the receiving opening and extends along the circumference of the receiving opening, and the thickness of the edge is smaller than the thickness of the supporting section.

[0015] By adopting the above technical solution, since an edge is provided on the inner side of the fitting section, the edge is located at the receiving opening and extends circumferentially along the receiving opening, so that the edge can increase the structural strength of the fitting section at the receiving opening to ensure the shape of the receiving opening, thereby avoiding possible damage such as tearing of the fitting section at the receiving opening, thereby ensuring the sealing between the atomizer mask and the patient's face; since the thickness of the edge is less than the thickness of the supporting section, the structural strength of the fitting section at the receiving opening is ensured, and the fitting section at the receiving opening is also easier to deform than the supporting section, thereby avoiding the situation where the fitting section is difficult to deform due to the existence of the edge.

[0016] Optionally, the thickness D1 of the supporting section satisfies: 1 mm ≤ D1 ≤ 3 mm; and / or the thickness D2 of the fitting section satisfies: 0.3 mm ≤ D2 ≤ 0.7 mm.

[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. 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 to ensure the patient's wearing comfort.

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

[0019] Optionally, one of the mouth wall of the installation opening 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 mouth wall of the installation port and the supporting 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 supporting member are assembled together, the connecting rib is located in the connecting groove, which on the one hand increases the sealing between the sealing member and the supporting member, and on the other hand increases the connection stability between the two.

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

[0022] By adopting the above technical scheme, since the connecting rib is provided with a fixing hole and the groove wall of the connecting groove is provided with a fixing column extending into the fixing hole, the fixed connection between the sealing member and the supporting member is realized to increase the connection stability between the two; at the same time, the fixing hole and the fixing column can be hidden in the connecting groove, which on the one hand makes the outer contour of the atomizing mask more regular to improve the appearance quality of the atomizing mask, and on the other hand avoids the situation where the structure for fixing the sealing member and the supporting member is exposed to the outside of the atomizing mask and is easy to hide dirt, so as to ensure the cleanliness of the atomizing mask and reduce the difficulty of cleaning the atomizing mask.

[0023] Optionally, one of the side wall of the connecting groove and the side wall 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 scheme, since one of the side wall of the connecting groove and the side wall 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, the cooperation between the limiting rib and the limiting groove can be utilized to realize the stopping of the sealing component and the supporting component in the direction of separation between the two, so as to increase the connection stability between the sealing component and the supporting component, and at the same time, the connection area between the sealing component and the supporting component is increased, so as to further increase the connection stability between the sealing component and the supporting component and the sealing between the two, and it can also make the sealing path between the sealing component and the supporting component more tortuous, so as to further improve the sealing between the two.

[0025] Optionally, the supporting member is provided with an exhaust hole, and the atomizing mask further comprises a valve plate arranged at the exhaust hole, and the valve plate is capable of relative movement with the supporting member so that the valve plate has an open position in which the exhaust hole is fully opened, and a closed position in which a partial area of ​​the exhaust hole is blocked, and 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 atomizing mask of the present application exhales, the valve plate is in a closed position, so that the valve plate blocks part of the exhaust hole, and then the mist in the delivery cavity enters the patient's respiratory tract under the action of the patient's inhalation. When the patient exhales, the valve plate moves from the closed position to the open position under the action of the patient's exhalation, so that the valve plate fully opens the exhaust hole, so that the gas exhaled by the patient is discharged from the delivery cavity through the exhaust hole. Since 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, and then when the patient inhales, the outside air can enter the delivery cavity through the air leakage channel, so as to reduce the patient's breath holding feeling when inhaling, and further improve the patient's comfort.

[0027] Optionally, the valve plate includes a clamping portion, a sealing portion, and a thin-walled portion arranged between the clamping portion and the sealing portion, and the clamping portion is clamped to the supporting member. When the valve plate is in the open position, the thin-walled portion undergoes elastic deformation to apply a force to the sealing portion to move toward the closed position.

[0028] By adopting the above technical solution, since the clamping part is clamped to the supporting member, the valve plate is connected to the supporting member by clamping, which increases the connection stability between the valve plate and the supporting member on the one hand, and reduces the difficulty of assembling the valve plate on the other hand, thereby improving the production efficiency of the atomizing mask; when the valve plate is in the open position, the thin-walled part undergoes elastic deformation and exerts a force on the sealing part to move toward the closed position, so that when the patient exhales, the sealing part can move toward the closed position under the action of the thin-walled part, thereby realizing that the sealing part can automatically close the exhaust hole.

[0029] Optionally, the outer periphery of the blocking portion has a connecting section and an avoidance section, the connecting section is connected to the thin-walled portion, and when the valve plate is in the closed position, the air leakage channel is formed between the avoidance section and the hole wall of the exhaust hole, and the flow area S of the air leakage channel satisfies: 5mm 2 ≤S≤50mm 2 .

[0030] By adopting the above technical solution, since the area S of the air leakage channel satisfies: 5mm 2 ≤S≤50mm 2On the one hand, it reduces the feeling of breath holding when the patient inhales, so as to improve the patient's user experience. On the other hand, it ensures that more aerosol can enter the patient's respiratory tract when the patient inhales, so as to ensure the atomization treatment effect on the patient.

[0031] Optionally, the outer wall of the supporting member is arranged flush with and in conformity with the outer wall of the sealing member;

[0032] And / or, the raised portion is configured to conform to the shape of the nose bridge.

[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 touch feel of the patient is improved on the other hand, so as to improve the patient's usage experience. In addition, it avoids the situation where dirt and grime are easily hidden due to the presence of a step between the sealing component and the supporting component, so as to ensure the cleanliness of the atomizing mask and facilitate the patient to clean the atomizing mask.

[0034] Since the raised portion is configured to conform to the shape of the bridge of the nose, the raised portion can better accommodate the patient's nose, and the sealing component can better deform according to the patient's nose contour to ensure the adaptability of the sealing component to the patient's nose, thereby ensuring the sealing between the atomizer 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 in the present 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 fitting the patient's face and a supporting end opposite to the fitting end, the fitting end is provided with a receiving port that can simultaneously accommodate the patient's mouth and nose, the supporting end is provided with a raised portion that can cover at least part of the patient's nose area and a mounting port located below the raised portion, the supporting member is provided at the mounting port and is spliced ​​with the sealing member to form a delivery cavity, and then the supporting member can form an avoidance with the raised portion, so that the portion of the sealing member corresponding to the patient's nose area can undergo a large deformation to increase the seal. The deformation ability of the sealing component enables the sealing component to adapt to the nasal contours of various patients, so as to increase the sealing between the nebulizer mask and the patient's face, thereby ensuring the nebulizer treatment effect on the patient; in addition, since the part of the sealing component corresponding to the patient's nasal area can undergo a large deformation, it is avoided that a large pulling force is applied to the nebulizer mask by the headband to ensure the sealing between the nebulizer mask and the patient's face, thereby reducing the contact force between the nebulizer mask and the patient's face, thereby avoiding the situation where the patient's face is prone to indentation to a certain extent, thereby greatly improving the patient's comfort in wearing the nebulizer mask.

[0037] 2. The sealing component in the present application includes a fitting section extending along the circumference of the accommodating opening and a supporting section extending along the circumference of the mounting opening. The thickness of the supporting section is greater than the thickness of the fitting section, thereby making the fitting end used to fit the patient's face softer, so that the fitting end is easier to deform. On the one hand, it 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 atomizer mask can adapt to more patient nasal contours, further increase the flexibility of the atomizer mask and further improve the sealing between the atomizer mask and the patient's face.

[0038] 3. The inner side of the fitting section in the present application is provided with an edge, which is located at the receiving opening and extends circumferentially along the receiving opening, so that the edge can increase the structural strength of the fitting section at the receiving opening to ensure the shape of the receiving opening, thereby avoiding possible damage such as tearing of the fitting section at the receiving opening, thereby ensuring the sealing between the atomizer mask and the patient's face; the thickness of the edge is less than the thickness of the supporting section, thereby ensuring the structural strength of the fitting section at the receiving opening and making the fitting section at the receiving opening easier to deform than the supporting section, so as to avoid the situation where the fitting section is difficult to deform due to the existence of the edge.

In the description of this specification, the description with reference to the terms "implementation method", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0059] Reference Figures 1 to 12 , discloses an atomizing mask, which is used to connect to an atomizing cup to deliver the aerosol generated by the atomizing cup to the airway entrance of a patient, and comprises a sealing component 1 and a supporting component 2, wherein the sealing component 1 has a fitting end for fitting the patient's face and a supporting end opposite to the fitting end, wherein the fitting end is provided with a receiving opening 11 capable of simultaneously accommodating the patient's mouth and nose, and the supporting end is provided with a protruding portion 12 capable of covering at least a partial area of ​​the patient's nose and a mounting opening 13 located below the protruding portion 12; the supporting component 2 is provided at the mounting opening 13 and is spliced ​​with the sealing component 1 to form a delivery cavity, the supporting component 2 is provided with a connecting hole 21 for connecting the atomizing cup, the connecting hole 21 is connected to the delivery cavity, and the rigidity of the supporting component 2 is greater than that of the sealing component 1.

[0060] It can be understood that the sealing member 1 has elasticity so that the sealing member 1 can be deformed.

[0061] It should be noted that the sealing component 1 mentioned above has a fitting end for fitting the patient's face, which means that after the nebulizer mask is worn on the patient's face, the fitting end is in contact with the patient's face; the raised portion 12 mentioned above can cover at least part of the patient's nose, which means that after the nebulizer mask is worn on the patient's face, the projection of the raised portion 12 toward the patient's face at least covers at least part of the patient's nose.

[0062] When using the nebulizer mask in the present application, the nebulizer cup is connected to the connecting hole 21 so that the nebulizer cup is connected to the delivery chamber, and then the nebulizer mask is worn on the patient's face using a headband so that the fitting end of the sealing member 1 contacts the patient's face, and the patient's mouth and nose are simultaneously located in the accommodating port 11, so that the aerosol generated in the nebulizer cup flows through the delivery chamber to the patient's airway entrance for inhalation treatment by the patient.

[0063] Since the rigidity of the support member 2 is greater than that of the sealing member 1, the sealing member 1 is softer 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 arranged at the installation opening 13, the installation opening 13 is located below the protrusion 12, and the protrusion 12 can cover at least part of the patient's nose area, thereby allowing the support member 2 to form an avoidance with the protrusion 12, so that the part of the sealing member 1 corresponding to the patient's nose area can undergo a larger deformation, thereby increasing the deformation ability of the sealing member 1, so that the sealing member 1 can adapt to the nasal contours of a variety of patients, thereby increasing the sealing between the nebulizer mask and the patient's face, thereby ensuring the nebulizer treatment effect on the patient.

[0064] In addition, since the portion of the sealing component 1 corresponding to the patient's nasal area can undergo a large deformation, it is avoided that a large pulling force is applied to the nebulizer mask using a headband to ensure the sealing between the nebulizer mask and the patient's face. This reduces the contact force between the nebulizer mask and the patient's face, and to a certain extent avoids the occurrence of indentations on the patient's face, thereby greatly improving the comfort of the patient wearing the nebulizer mask.

[0065] Furthermore, since the sealing component 1 can undergo a large deformation, the nebulizer mask can be adapted to a variety of patients, thereby increasing the sealing between the nebulizer mask and the patient's face, avoiding irritation of the patient's eyes by the drug mist due to the gap between the nebulizer mask and the patient's nose, thereby improving the patient's comfort during nebulizer treatment, thereby improving the patient's usage experience, and at the same time avoiding the waste of drugs, so that more drug mist can be inhaled into the patient's respiratory tract, thereby improving the nebulizer treatment effect on the patient.

[0066] The present application does not make any specific limitation on the materials used to make the sealing member 1 and the supporting member 2. Preferably, the sealing member 1 is made of a silicone material to ensure the softness and deformation ability of the sealing member 1, thereby improving the wearing experience of the patient, and the sealing member 1 can be made transparent to achieve visibility of the atomization treatment; the supporting member 2 is made of a polyvinyl chloride material to ensure the rigidity of the supporting member 2 to ensure the shape of the atomization mask, and the supporting member 2 can also be made transparent to achieve visibility of the atomization treatment. Of course, in other embodiments, the sealing member 1 can also be made of other materials with less rigidity than the supporting member 2, such as rubber, etc.; the supporting member 2 can also be made of other hard plastic materials, such as polypropylene, etc.

[0067] The present application does not specifically limit the structure of the sealing member 1. Preferably, refer to Figures 4 to 9 The sealing component 1 includes a fitting section 14 extending along the circumference of the accommodating opening 11 and a supporting section 15 extending along the circumference of the mounting opening 13 . The thickness of the supporting section 15 is greater than that of the fitting section 14 .

[0068] Since the thickness of the supporting section 15 is greater than the thickness of the fitting section 14, and the fitting section 14 is extended along the circumference of the accommodating opening 11, and the supporting section 15 is extended along the circumference of the mounting opening 13, the fitting end for fitting the patient's face is softer, so that the fitting end is easier to deform, which can improve the patient's wearing experience on the one hand, and can also make the fitting end fit the patient's facial skin better on the other hand, so that the atomizing mask can adapt to more patient's nasal contours, further increase the flexibility of the atomizing mask, and further improve the sealing between the atomizing mask and the patient's face.

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

[0070] Better, refer to Figures 4 to 9 The fitting section 14 includes a first section 141 located at the bridge of the patient's 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 component 1 can undergo a larger deformation below the patient's mouth and nose, so that the nebulizer mask can be used by different patients, to increase the flexibility of the nebulizer mask and ensure the sealing between the nebulizer mask and the patient's face.

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

[0072] It can be 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 has a shape-retaining effect on the sealing component 1.

[0073] Of course, in other embodiments, the width of the fitting section 14 may also be set to be a constant structure along the circumference of the receiving opening 11 .

[0074] Further, see Figure 4 , Figure 5 and Figure 6 The inner side of the fitting section 14 is provided with an edge 144, which is located at the receiving opening 11 and extends along the circumference of the receiving opening 11, so that the edge 144 can increase the structural strength of the fitting section 14 at the receiving opening 11 to ensure the shape of the receiving opening 11, thereby avoiding possible damage such as tearing of the fitting section 14 at the receiving opening 11, thereby ensuring the sealing between the atomizing mask and the patient's face. The shape of the receiving opening 11 can prevent the fitting section 14 at the receiving opening 11 from being torn or damaged, thereby ensuring the sealing between the atomizing mask and the patient's face; the thickness along the edge 144 is less than the thickness of the supporting 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 supporting section 15, thereby avoiding the situation where the fitting section 14 is difficult to deform due to the existence 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 facing away from the patient's face after the atomizing mask is worn on the patient's face; the thickness along 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, referring to Figure 5The thickness D1 of the support segment 15 satisfies: 1mm≤D1≤3mm. On the one hand, it can make the support segment have a certain strength so that the support segment can maintain the shape of the sealing component 1. On the other hand, it can ensure that when the support component 2 applies pressure to the sealing component 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 supporting segment 15 may also be set to be greater than 3 mm or less than 1 mm.

[0078] In a preferred embodiment, referring to Figure 5 The thickness D2 of the fitting section 14 satisfies: 0.3mm≤D2≤0.7mm, thereby ensuring the deformation ability of the fitting section 14 so that the fitting section 14 can better fit the patient's face, thereby increasing the patient's wearing comfort and the sealing between the atomizer mask and the patient's face.

[0079] Of course, in other embodiments, the thickness D2 of the fitting section 14 may 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 difficulty of producing the sealing member 1 .

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

[0082] Specifically, the connecting groove 131 is arranged on the mouth wall of the installation opening 13, and the connecting rib 22 is arranged on the edge of the supporting member 2. That is, the installation opening 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] Better, refer to Figure 3 and Fig. 9 The connecting groove 131 is extended along the circumference of the installation opening 13, and the connecting rib 22 is extended along the circumference of the supporting member 2 to increase the matching area between the connecting rib 22 and the connecting groove 131, so as to further increase the sealing between the sealing member 1 and the supporting member 2 and increase the connection stability between the two.

[0084] The present application does not specifically limit the connection method between the sealing member 1 and the supporting member 2, and any one of the following embodiments may be adopted:

[0085] Embodiment 1, in this embodiment, refer 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 column 132 extending into the fixing hole 221, thereby realizing the fixed connection between the sealing member 1 and the supporting member 2 to increase the connection stability between the two; at the same time, the fixing hole 221 and the fixing column 132 can be hidden in the connecting groove 131, on the one hand, the outer contour of the atomizing mask is more regular to improve the appearance quality of the atomizing mask, and on the other hand, it avoids the situation that the structure for fixing the sealing member 1 and the supporting member 2 is exposed to the outside of the atomizing mask and is easy to hide dirt, so as to ensure the cleanliness of the atomizing mask and reduce the difficulty of cleaning the atomizing mask.

[0086] Further, see Figure 7 One of the side walls of the connecting groove 131 and the side walls of the connecting rib 22 is provided with a limiting groove 133, and the other of the two is provided with a limiting rib 222 extending into the limiting groove 133, and then the limiting rib 222 can cooperate with the limiting groove 133 to achieve stopping of the sealing component 1 and the supporting component 2 in the direction of separation between the two, so as to increase the connection stability between the sealing component 1 and the supporting component 2, and at the same time increase the connection area between the sealing component 1 and the supporting component 2, so as to further increase the connection stability between the sealing component 1 and the supporting component 2 and the sealing between the two, and can also make the sealing path between the sealing component 1 and the supporting component 2 more tortuous, so as to further improve the sealing between the two.

[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 , so that the limiting rib 222 can also increase the structural strength of the connecting rib 22 to ensure the structural strength of the supporting member 2 .

[0088] Preferably, the limiting groove 133 is extended along the circumference of the installation opening 13, and the limiting rib 222 is extended along the circumference of the support member 2 to increase the connection area between the limiting rib 222 and the limiting groove 133, so as to further increase the connection stability between the sealing member 1 and the support member 2.

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

[0090] Embodiment 2. In this embodiment, the sealing member 1 and the supporting member 2 are integrally formed by a two-color injection molding process to achieve a fixed connection between the sealing member 1 and the supporting member 2, thereby increasing the connection stability between the sealing member 1 and the supporting member 2 and increasing the sealing performance between the two.

[0091] Of course, in other embodiments, the sealing member 1 may also be fixedly connected to the supporting member 2 by gluing or fixing with fasteners.

[0092] In a preferred embodiment, referring to Figure 1 , Figure 2 , Figure 3 , Fig.10 , Fig.11 and Fig.12 The support member 2 is provided with an exhaust hole 23, and the atomizing mask also includes a valve plate 3 arranged 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 in which the exhaust hole 23 is fully opened and a closed position in which a partial area of ​​the exhaust hole 23 is blocked. 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 atomizing mask of the present application exhales, the valve plate 3 is in the closed position, so that the valve plate 3 blocks part of the exhaust hole 23, and then the aerosol in the delivery cavity enters the patient's respiratory tract under the action of the patient's exhalation. When the patient exhales, the valve plate 3 moves from the closed position to the open position under the action of the patient's exhalation, so that the valve plate 3 fully opens the exhaust hole 23, so that the gas exhaled by the patient is discharged from the delivery cavity through the exhaust hole 23. Since 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, and then when the patient inhales, the outside air can enter the delivery cavity through the air leakage channel 34, so as to reduce the patient's breath holding feeling when inhaling, and further improve the patient's comfort.

[0094] Specifically, refer to Figures 1 to 3 The valve plate 3 is arranged on the outside of the supporting 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 supporting 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 where the supporting member 2 is located, so that the valve plate 3 can avoid the patient's face to ensure the normal movement of the valve plate 3 between the open position and the closed position.

[0095] The present application does not specifically limit the structure of the valve plate 3. Preferably, refer to Fig.12The valve plate 3 includes a clamping portion 31, a sealing portion 32 and a thin-walled portion 33 arranged between the clamping portion 31 and the sealing portion 32. The clamping portion 31 is clamped to the supporting 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 sealing portion 32 to move toward the closed position.

[0096] It is understandable that the valve plate 3 is a structure made of plastic material, and the thickness of the thin-walled portion 33 is smaller than the thickness of the clamping portion 31 and the thickness of the blocking portion 32, so that the thin-walled portion 33 can be more easily elastically deformed than the blocking portion 32 and the clamping portion 31.

[0097] Since the clamping portion 31 is clamped to the supporting member 2, the valve plate 3 is connected to the supporting member 2 by clamping, which increases the connection stability between the valve plate 3 and the supporting member 2 on the one hand, and reduces the difficulty of assembling the valve plate 3 on the other hand, thereby improving the production efficiency of the atomizing mask; when the valve plate 3 is in the open position, the thin-walled portion 33 undergoes elastic deformation and exerts a force on the sealing portion 32 to move toward the closed position, so that when the patient exhales, the sealing portion 32 can move toward the closed position under the action of the thin-walled portion 33, thereby achieving the effect of the sealing portion 32 being able to automatically close the exhaust hole 23.

[0098] Preferably, the clamping portion 31 and the blocking portion 32 are both sheet structures, and the thin-walled portion 33 is a rib-wall structure to reduce the weight of the valve plate 3 so that the blocking portion 32 can move toward the open position under the action of the patient's exhalation.

[0099] Specifically, refer to Fig.12 The clamping portion 31 has a clamping protrusion 311 , and the supporting member 2 is provided with a clamping hole 24 . The clamping protrusion 311 is clamped and matched with the clamping hole 24 to achieve the clamping fit between the clamping portion 31 and the supporting member 2 .

[0100] Further, see Fig.10 and Fig.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 avoid the valve plate 3 from moving excessively and moving into the inside of the supporting member 2, thereby ensuring the sealing effect of the valve plate 3 on the exhaust hole 23.

[0101] Furthermore, the outer periphery of the blocking portion 32 has a connecting section and an avoidance section, the connecting section is connected to the thin-walled portion 33, and when the valve plate 3 is in the closed position, a gas leakage channel 34 is formed between the avoidance section and the hole wall of the exhaust hole 23, and the flow area S of the gas leakage channel 34 satisfies: 5mm 2 ≤S≤50mm 2On the one hand, it reduces the feeling of breath holding when the patient inhales, so as to improve the patient's user experience. On the other hand, it ensures that more aerosol can enter the patient's respiratory tract when the patient inhales, so as to ensure the atomization treatment effect on the patient.

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

[0103] In other embodiments, the valve plate 3 includes a plate body, a movable column arranged on the plate body, and a spring arranged on the movable column. The movable column is penetrated through the support member 2. The spring acts on the support member 2 and applies an elastic force to the plate body to move toward the closed position. Subsequently, when the patient exhales, the gas exhaled by the patient applies a force to 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] The present application does not specifically limit the positions of the exhaust hole 23 and the connection hole 21. Preferably, refer to Figures 1 to 3 The exhaust hole 23 is located below the connecting hole 21. On the one hand, the valve plate 3 and the atomizing cup can be avoided to ensure the normal movement of the valve plate 3, and on the other hand, the appearance quality of the atomizing mask is improved. In other embodiments, the exhaust hole 23 can also be located above or on the side of the connecting hole 21.

[0105] In a preferred embodiment, referring to Figures 1 to 3 The outer wall of the supporting member 2 is flush with the outer wall of the sealing member 1, that is, the connection position between the supporting member 2 and the sealing member 1 is a smooth transition, which improves the appearance quality of the atomizing mask on the one hand, and improves the patient's touch feel on the other hand, so as to improve the patient's usage experience. In addition, it avoids the situation where dirt and grime are easily hidden due to the presence of a step between the sealing member 1 and the supporting member 2, so as to ensure the cleanliness of the atomizing mask and facilitate the patient to clean the atomizing mask.

[0106] In a preferred embodiment, referring to Figures 1 to 3 The raised portion 12 is configured to conform to the shape of the nose bridge, that is, the raised portion 12 is designed to imitate the nose bridge, so that the raised portion 12 can better accommodate the patient's nose, and the sealing component can better deform according to the patient's nose contour to ensure the adaptability of the sealing component 1 to the patient's nose, thereby ensuring the sealing between the atomizer mask and the patient.

[0107] It should be noted that the above-mentioned raised portion 12 is configured to conform to the shape of the bridge of the nose, which means that the raised portion 12 is gradually arranged from bottom to top toward the fitting end, and the two sides of the raised portion 12 are gradually arranged in a direction away from each other and close to the fitting end.

[0108] In a preferred embodiment, referring to Fig.10 and Fig.11 , extension plates 25 are provided on opposite sides of the support member 2, and each extension plate 25 is provided with at least two headband holes 251, that is, when the headband is connected to the atomizing mask, one end of the headband is first inserted into one of the headband holes 251, and then the headband is folded back and inserted into the other headband hole 251 to increase the connection stability between the headband and the atomizing mask, and after the atomizing mask is worn on the patient's face, the two extension parts are respectively 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, two headband holes 251 are provided on each extension plate 25 to reduce the difficulty of installing the headband while ensuring the stability of the connection between the headband and the supporting structure 2.

[0110] In a preferred embodiment, referring to Fig.10 and Fig.11 The connecting hole 21 is a stepped hole, and the end with a smaller aperture of the stepped hole is located on the side of the supporting member 2 close to the sealing member 1, so that the atomizing mask in the present application can be connected to atomizing cups of different models to increase the flexibility of the atomizing mask.

[0112] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0113] The above is only an embodiment of the present application and is not intended to limit the present application.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
