Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to a connector for a patient breathing interface and a patient breathing interface. Background Art

[0002] A respiratory mask is a medical device that covers the patient's mouth and nose to deliver oxygen or mixed gases into the patient's respiratory tract, increasing the patient's oxygen intake and gas pressure in the respiratory tract to improve the patient's respiratory function.

[0003] At present, a respiratory mask generally includes a bracket, a cushion assembly located on the inner side of the bracket, and a bend or connector located on the outer side of the bracket. The bend or connector is used to connect the breathing circuit, and the bend or connector is provided with an exhaust hole so that the carbon dioxide exhaled by the patient can be discharged through the exhaust hole; however, since the bend or connector is manufactured by an injection molding process and the bend or connector is provided with an exhaust hole, the mold structure used to produce the bend or connector is relatively complicated, which increases the difficulty of producing the bend or connector.

[0004] In order to reduce the difficulty of producing elbows or connectors, some manufacturers use a separate exhaust structure for exhaust, so that the design of the exhaust hole on the elbow or connector can be eliminated. However, this increases the production cost of the patient's breathing interface and also increases the weight of the patient's breathing interface, thereby affecting the patient's experience. In addition, in order to reduce the noise generated when the gas is discharged through the exhaust hole, noise reduction cotton is usually set at the exhaust hole. In order to ensure the noise reduction effect of the noise reduction cotton, the noise reduction cotton needs to be replaced regularly. However, the existing method of replacing the noise reduction cotton is relatively complicated, which also affects the patient's experience. Summary of the invention

[0005] The present application provides a connector for a patient respiratory interface to reduce the production cost and weight of the patient respiratory interface to improve the patient's user experience.

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

[0007] A connector for a patient breathing interface, the connector comprising a first connection end, a second connection end and a ventilation duct located between the first connection end and the second connection end, the first connection end being connectable to the patient breathing interface, the second connection end being connectable to a breathing circuit, the connector further comprising an exhaust component having a plurality of exhaust holes, the side wall of the ventilation duct being provided with an exhaust opening, the exhaust component being adapted to be installed on the ventilation duct at the exhaust opening.

[0008] By adopting the above-mentioned technical scheme, after the patient wears the patient breathing interface with the connector in the present application, the carbon dioxide exhaled by the patient is discharged through the exhaust hole provided in the exhaust component. Since the exhaust component and the ventilation duct are adapted and installed at the exhaust opening, the problem of complex production mold caused by the exhaust hole being directly provided on the side wall of the ventilation duct is avoided, thereby reducing the production difficulty of the connector, thereby improving the yield of the connector, and further reducing the production cost of the connector, thereby reducing the production cost of the patient breathing interface with the connector in the present application.

[0009] At the same time, the carbon dioxide exhaled by the patient is discharged through the exhaust hole connected to the ventilation duct. Compared with the solution of discharging carbon dioxide through a separate exhaust structure in the prior art, on the one hand, the carbon dioxide is discharged without obstruction, so that the carbon dioxide can be discharged more smoothly, thereby improving the smoothness of the patient's breathing, and at the same time reducing the noise generated during the discharge of carbon dioxide, thereby improving the patient's user experience. On the other hand, the weight of the patient's breathing interface is reduced, thereby reducing the patient's wearing burden, thereby further improving the patient's user experience.

[0010] Optionally, the exhaust component is detachably connected to the ventilation duct.

[0011] By adopting the above technical solution, since the exhaust component can be detachably connected to the ventilation duct, the difficulty of assembling the exhaust component is reduced, thereby improving the production efficiency of the connector. At the same time, the exhaust component or the ventilation duct can be replaced separately to reduce the maintenance cost of the connector.

[0012] Optionally, the ventilation duct is provided with first clamping parts located at both ends of the exhaust opening, and both ends of the exhaust component are provided with second clamping parts, and the second clamping parts can be engaged with the first clamping parts to fix the exhaust component.

[0013] By adopting the above technical solution, when assembling the exhaust component, the exhaust component is first aligned with the exhaust opening so that the second engaging portion is aligned with the first engaging portion, and then a force is applied to the exhaust component in the direction of the ventilation pipe, thereby causing the exhaust component to move in the direction of the ventilation pipe, and finally causing the second engaging portion and the first engaging portion to engage with each other to complete the assembly of the exhaust component. In this process, it is only necessary to apply a force to the exhaust component in the direction of the ventilation pipe, thereby greatly reducing the difficulty of assembling the exhaust component, thereby improving the production efficiency of the connector and reducing the production cost of the connector, thereby improving the production efficiency of the patient breathing interface having the connector in the present application.

[0014] Optionally, the ventilation pipe is a straight pipe structure;

[0015] Alternatively, the ventilation duct is a bent pipe structure.

[0016] By adopting the above technical solution, since the ventilation pipe is a straight pipe structure, the connector can be connected to an elbow or the connector can be directly connected to the breathing circuit to increase the flexibility of the connector.

[0017] Since the ventilation duct is a bent pipe structure, the connector is an elbow, which reduces the difficulty of producing the elbow, improves the yield of the elbow, and further reduces the production cost of the elbow.

[0018] The present application also provides another connector for a patient breathing interface to facilitate the replacement of noise reduction cotton, thereby improving the patient's user experience.

[0019] A connector for a patient breathing interface, the connector comprising a first connection end, a second connection end and a ventilation duct located between the first connection end and the second connection end, the first connection end being connectable to the patient breathing interface, the second connection end being connectable to a breathing circuit, a side wall of the ventilation duct being provided with a plurality of exhaust holes, the connector further comprising:

[0020] A card cover component, the card cover component is installed on the ventilation duct and covers the exhaust hole area, and the card cover component is provided with an exhaust groove;

[0021] A noise reduction component is installed between the side wall of the ventilation duct and the cover component, so that the gas discharged through the exhaust hole is discharged through the exhaust groove after the noise is reduced by the noise reduction component.

[0022] By adopting the above-mentioned technical scheme, after the patient wears the patient breathing interface with the connector in the present application, the carbon dioxide exhaled by the patient flows to the noise reduction component through the exhaust hole, and then the carbon dioxide passes through the noise reduction component and is discharged through the exhaust groove, so as to achieve noise reduction of the patient's breathing interface; when replacing the noise reduction component, the card cover component is separated from the ventilation duct, and then the noise reduction component is replaced. In this process, the operating steps for the patient to replace the noise reduction component are simplified, thereby achieving the effect of facilitating the patient to replace the noise reduction component, while also improving the efficiency of replacing the noise reduction component, thereby improving the patient's user experience.

[0023] Optionally, the side wall of the ventilation duct is provided with an exhaust opening, and the connector further comprises an exhaust component having a plurality of exhaust holes, and the exhaust component is adapted to be installed on the ventilation duct at the exhaust opening.

[0024] By adopting the above-mentioned technical scheme, since the exhaust component has multiple exhaust holes, and the exhaust component and the ventilation pipe are installed in a matching manner at the exhaust opening, the difficulty of producing the ventilation pipe is reduced, and the yield of the ventilation pipe is improved, thereby reducing the production cost of the ventilation pipe, and further reducing the production cost of the patient breathing interface with the connector in the present application; and, compared with a separate exhaust structure, on the one hand, the production cost of the connector is further reduced, and on the other hand, the weight of the patient breathing interface is reduced, thereby reducing the patient's wearing burden, and further improving the patient's usage experience.

[0025] Optionally, the exhaust component has a central area and a side area surrounding the central area, and the exhaust hole is provided in the central area;

[0026] And / or, the side area is provided with an exhaust notch, and the exhaust notch and the mouth wall of the exhaust opening together form the exhaust hole.

[0027] By adopting the above technical solution, since the exhaust hole is arranged in the central area, the exhaust hole can avoid the wall of the exhaust opening to increase the contact area between the exhaust component and the wall of the exhaust opening, thereby increasing the connection stability between the exhaust component and the ventilation duct to ensure the service life of the connector, thereby improving the patient's usage experience.

[0028] Since the exhaust notch and the mouth wall of the exhaust opening jointly form an exhaust hole, and the exhaust notch is arranged in the side area of ​​the exhaust component, the production difficulty of the exhaust component is reduced, so as to improve the production efficiency of the exhaust component and reduce the production cost of the exhaust component, thereby reducing the production cost of the connector.

[0029] Optionally, both ends of the cover member are provided with connecting parts, and the ventilation duct is provided with fixing parts corresponding to the connecting parts, and the connecting parts can be snap-fitted or magnetically matched with the fixing parts to fix the cover member.

[0030] By adopting the above technical scheme, when replacing the noise reduction component, the card cover component is first disassembled to release the card connection or magnetic engagement with the fixing part of the connecting part, and then the noise reduction component can be replaced. Through the arrangement of the connecting part and the fixing part, on the one hand, the connection stability between the card cover component and the ventilation duct is increased to increase the stability of the noise reduction component, thereby ensuring the noise reduction effect of the noise reduction component. On the other hand, the card cover component is easy to disassemble and assemble, so as to achieve the effect of facilitating the patient to replace the noise reduction component, thereby further improving the patient's use experience.

[0031] Optionally, one end of the card cover component is hinged to the ventilation duct, the other end of the card cover component is provided with a connecting portion, the ventilation duct is provided with a fixing portion, and the connecting portion can be snapped or magnetically matched with the fixing portion to fix the card cover component.

[0032] By adopting the above technical scheme, when replacing the noise reduction component, force is first applied to the end of the card cover component away from its own hinged end so that the connecting part releases the clamping or magnetic engagement with the fixing part, and then force is continued to be applied to the end of the card cover component away from its own hinged end so that the card cover component rotates around its own hinged end, thereby exposing the noise reduction component to the outside of the ventilation duct, and then the noise reduction component can be replaced; because one end of the card cover component is hinged to the ventilation duct, and then when the card cover component rotates to expose the noise reduction component to the outside of the ventilation duct, the card cover component is still connected to the ventilation duct, so as to avoid the possible loss of the card cover component when the noise reduction component is replaced, and when the patient replaces the noise reduction component, it only needs to operate the end of the card cover component away from its own hinged end, so as to further reduce the difficulty of replacing the noise reduction component, further improve the patient's replacement efficiency of the noise reduction component, and further improve the patient's use experience.

[0033] Optionally, the cover member includes a first cover body and a second cover body which are arranged opposite to each other, one end of the first cover body is provided with a connecting portion, one end of the second cover body is provided with a fixing portion which can be snap-connected or magnetically matched with the connecting portion, and the other end of the first cover body and the other end of the second cover body are hinged to the ventilation duct;

[0034] Alternatively, the other end of the first cover body and the other end of the second cover body are hinged to each other through a connecting portion.

[0035] By adopting the above technical solution, when replacing the noise reduction component, first apply a force in the direction of moving away from each other to the ends of the first cover body and the second cover body away from the hinged end, so that the connecting part and the fixing part are released from the snap connection or magnetic engagement, and then continue to rotate the first cover body and the second cover body, so that the noise reduction component is exposed to the outside of the ventilation duct, and then the noise reduction component can be replaced; because one end of the first cover body and the second cover body are both hinged to the ventilation duct, and then the first cover body and the second cover body are rotated to expose the noise reduction component to the outside of the ventilation duct, the first cover body and the second cover body are still connected to the ventilation duct, thereby avoiding the phenomenon that the card cover component is easily lost when the noise reduction component is replaced, thereby improving the patient's use experience; at the same time, when opening the card cover component, it is only necessary to operate the connection between the first cover body and the second cover body, so as to reduce the difficulty of replacing the noise reduction component.

[0036] Since the other end of the first cover body and the other end of the second cover body are hinged to each other through the connecting part, on the one hand, the difficulty of operation when replacing the noise reduction component is reduced to improve the efficiency of replacing the noise reduction component; on the other hand, the card cover component can be separated from the ventilation duct, so that when the noise reduction component is replaced, the card cover component can avoid the noise reduction component to reduce the difficulty of disassembly and assembly of the noise reduction component, so as to further improve the replacement efficiency of the noise reduction component.

[0037] Optionally, the ventilation duct is provided with positioning ribs located on both sides of the plurality of exhaust holes, and the cover component is located between the positioning ribs to position the cover component.

[0038] By adopting the above technical solution, after the card cover component is installed in the ventilation duct, the card cover component is located between the two positioning ribs. On the one hand, the positioning ribs can position the card cover component to facilitate the installation of the card cover component in place, thereby reducing the difficulty of assembling the card cover component and ensuring the fixing effect of the card cover component on the noise reduction component. On the other hand, the positioning ribs can also limit the card cover component to avoid the axial movement of the card cover component along the ventilation duct, thereby increasing the connection stability between the card cover component and the ventilation duct.

[0039] Optionally, the noise reduction component is fixedly connected to the card cover component;

[0040] Alternatively, the noise reduction component and the card cover component are provided separately.

[0041] By adopting the above technical solution, since the noise reduction component is fixedly connected to the card cover component, the stability of the noise reduction component is increased. At the same time, when the noise reduction component is replaced, it is only necessary to remove the card cover component and replace it together with the card cover component, so as to further achieve the effect of facilitating the replacement of the noise reduction component.

[0042] Since the noise reduction component and the card cover component are separately arranged, the noise reduction component can be replaced separately, so as to reduce the replacement cost of the noise reduction component, thereby reducing the use cost of the patient, and further improving the patient's use experience.

[0043] Optionally, the card cover component has a supporting rib, and an accommodating space with an opening on the side is formed between the supporting rib and the card cover component, and the noise reduction component is arranged in the accommodating space via the opening.

[0044] By adopting the above technical scheme, since the noise reduction component is arranged in the accommodating space, the noise reduction component can move together with the card cover component, so that the noise reduction component and the ventilation duct can be separated when the card cover component is opened, so as to achieve the effect of facilitating the patient to separate the noise reduction component from the ventilation duct; and, since the side of the accommodating space has an opening, when separating the noise reduction component from the card cover component, the patient only needs to apply a pulling force to the noise reduction component toward the side where the opening is located, thereby achieving the effect of facilitating the separation of the noise reduction component from the card cover component, and when installing the noise reduction component into the accommodating space, it is only necessary to align the noise reduction component with the opening of the accommodating space and apply a pushing force to the noise reduction component toward the accommodating space, so as to reduce the difficulty of installing the noise reduction component, thereby achieving the effect of facilitating the replacement of the noise reduction component.

[0045] Optionally, edges are provided on both sides of the card cover component extending inward, an accommodating space for accommodating the noise reduction component is formed between the edges, and the edges are provided with supporting protrusions located on the inner side of the noise reduction component.

[0046] By adopting the above technical solution, both sides of the card cover component are provided with edges extending inward, and a accommodating space for accommodating the noise reduction component is formed between the edges. After the noise reduction component is installed in the accommodating space, the edges can block the noise reduction component in the axial direction of the ventilation duct to increase the stability of the noise reduction component; and, since a supporting protrusion located on the inner side of the noise reduction component is provided along the edge, the supporting protrusion can support the noise reduction component, so that the noise reduction component can stay stably in the accommodating space, so as to further increase the stability of the noise reduction component, thereby ensuring the noise reduction effect of the noise reduction component.

[0047] Optionally, the noise reduction component includes noise reduction cotton and a support frame extending continuously along the circumference of the noise reduction cotton.

[0048] By adopting the above technical scheme, since the noise reduction component includes noise reduction cotton and a support frame extending continuously along the circumference of the noise reduction cotton, on the one hand, the support frame can support the noise reduction cotton to ensure the noise reduction effect of the noise reduction cotton, while ensuring the air permeability of the noise reduction cotton to ensure the exhaust efficiency of the exhaust hole; on the other hand, if the installation position of the noise reduction component deviates from the required installation position, the existence of the support frame will cause the cover component to be unable to be installed in place, so that the support frame can also play an anti-mistake effect to ensure the installation accuracy of the noise reduction component, thereby ensuring the noise reduction effect of the noise reduction component.

[0049] Optionally, the cross-sectional shape of the first connecting end is non-circular.

[0050] By adopting the above technical solution, since the cross-sectional shape of the first connecting end is non-circular, when the first connecting end is connected to the patient's respiratory interface, the first connecting end can also play an anti-mistake role to ensure the accuracy of the connector installation, and at the same time can also increase the connection stability between the connector and the patient's respiratory interface to ensure the treatment effect on the patient.

[0051] The present application also provides a patient breathing interface to reduce the weight and production cost of the patient breathing interface, so as to facilitate the replacement of noise reduction cotton and improve the patient's user experience.

[0056] a breathing tube connected to the connector and communicating with the cushion assembly through the connector;

[0057] A side arm is connected to the bracket and is used for wearing the patient breathing interface on the patient's face.

[0058] By adopting the above-mentioned technical solution, since the patient breathing interface in the present application adopts the above-mentioned connector, the production difficulty of the patient breathing interface is reduced, the production efficiency of the patient breathing interface is improved, the production cost of the patient breathing interface is reduced, and the effect of facilitating the replacement of noise reduction components is achieved, thereby improving the patient's user experience.

[0059] Optionally, the cushion assembly includes a support member connected to the bracket and a sealing cover provided on the support member, the support member has a vent hole, the sealing cover has a sealing rib extending out of the vent hole, and the sealing rib contacts the bracket.

[0060] By adopting the above technical solution, since the sealing cover has a sealing rib extending out of the vent hole, the sealing rib contacts the bracket, thereby increasing the sealing between the cushion assembly and the bracket. On the one hand, it avoids the phenomenon that the gas flows out through the gap between the cushion assembly and the bracket due to poor sealing between the two and generates noise, thereby reducing the noise of the patient's breathing interface to improve the patient's user experience. On the other hand, it improves the ventilation efficiency of the patient's breathing interface.

[0091] After the patient wears the patient breathing interface with the connector in the present application, the carbon dioxide exhaled by the patient is discharged through the exhaust hole 21 provided on the exhaust component 2. Since the exhaust component 2 and the ventilation duct 1 are adapted and installed at the exhaust opening 11, the problem of complex production mold caused by the exhaust hole 21 being directly provided on the side wall of the ventilation duct 1 is avoided, thereby reducing the production difficulty of the connector, thereby improving the yield of the connector, and further reducing the production cost of the connector, thereby reducing the production cost of the patient breathing interface with the connector in the present application.

Compared with the solution of discharging carbon dioxide through a separate exhaust structure 2 in the prior art, on the one hand, the carbon dioxide is discharged without obstruction, so that the carbon dioxide can be discharged more smoothly, thereby improving the smoothness of the patient's breathing, and at the same time reducing the noise generated during the discharge of carbon dioxide, thereby improving the patient's user experience. On the other hand, the weight of the patient's breathing interface is reduced, thereby reducing the patient's wearing burden, thereby further improving the patient's user experience.

[0093] The present application does not make any specific limitation on the connection method between the exhaust component 2 and the ventilation duct 1. Preferably, the exhaust component 2 can be detachably connected to the ventilation duct 1, thereby reducing the difficulty of assembling the exhaust component 2 to improve the production efficiency of the connector. At the same time, the exhaust component 2 or the ventilation duct 1 can also be replaced separately to reduce the maintenance cost of the connector.

[0094] The present application does not specifically limit the detachable connection method between the exhaust component 2 and the ventilation pipe 1.

[0112] After the patient wears the patient breathing interface with the connector in the present application, the carbon dioxide exhaled by the patient flows to the noise reduction component 4 through the exhaust hole 21, and then the carbon dioxide passes through the noise reduction part and is discharged through the exhaust groove 31, so as to achieve noise reduction of the patient's breathing interface; when replacing the noise reduction component 4, the card cover component 3 is separated from the ventilation duct 1, and then the noise reduction component 4 is replaced. In this process, the operating steps for the patient to replace the noise reduction component 4 are simplified, thereby achieving the effect of facilitating the patient to replace the noise reduction component 4, while also improving the efficiency of replacing the noise reduction component 4, thereby improving the patient's usage experience.

[0113] In a preferred embodiment, referring to Figure 1 and Figure 2 The side wall of the ventilation duct 1 is provided with an exhaust opening 11, and the connector also includes an exhaust component 2 with multiple exhaust holes 21. The exhaust component 2 is adapted to be installed at the exhaust opening 11 of the ventilation duct 1, thereby reducing the production difficulty of the ventilation duct 1 and improving the yield of the ventilation duct 1, thereby reducing the production cost of the ventilation duct 1, and further reducing the production cost of the patient breathing interface with the connector in the present application; and, compared with a separate exhaust structure, on the one hand, the production cost of the connector is further reduced, and on the other hand, the weight of the patient breathing interface is reduced, thereby reducing the wearing burden of the patient, and further improving the patient's use experience.

[0114] The present application does not specifically limit the location of the exhaust hole 21, and it can adopt any one or a combination of two of the following embodiments:

[0115] Embodiment 1, in this embodiment, refer to Figure 8 and Fig.10 The exhaust component 2 has a central area and a side area surrounding the central area. The exhaust hole 21 is arranged in the central area, so that the exhaust hole 21 can form an avoidance with the mouth wall of the exhaust opening 11 to increase the contact area between the exhaust component 2 and the mouth wall of the exhaust opening 11, thereby increasing the connection stability between the exhaust component 2 and the ventilation pipe 1 to ensure the service life of the connector, thereby improving the patient's usage experience.

[0116] Embodiment 2, in this embodiment, refer to Figure 1 , Figure 2 and Figure 7 The exhaust component 2 has a central area and side areas surrounding the central area. The side areas are provided with exhaust notches. The exhaust notches and the mouth wall of the exhaust opening 11 together form an exhaust hole 21, thereby reducing the production difficulty of the exhaust component 2, thereby improving the production efficiency of the exhaust component 2, and reducing the production cost of the exhaust component 2, thereby reducing the production cost of the connector.

[0117] It should be noted that other designs of the exhaust component 2 may refer to the exhaust component 2 in the first connector; of course, the exhaust component 2 in the first connector may also refer to the exhaust component 2 in this embodiment.

[0118] The present application does not specifically limit the connection method between the cover member 3 and the ventilation duct 1, and it can adopt any one of the following embodiments:

[0119] Embodiment 1. In this embodiment, referring to Figure 7Both ends of the cover member 3 are provided with connecting parts 32 , and the ventilation duct 1 is provided with a fixing part 13 corresponding to the connecting part 32 , and the connecting part 32 can be engaged or magnetically matched with the fixing part 13 to fix the cover member 3 .

[0120] It can be understood that two fixing portions 13 are provided corresponding to the connecting portions 32 and are respectively located on both sides of the exhaust opening 11 , and the fixing portions 13 and the connecting portions 32 are provided in a one-to-one correspondence.

[0121] When replacing the noise reduction component 4, the card cover component 3 is first disassembled to release the card connection or magnetic attraction between the connecting portion 32 and the fixing portion 13, and then the noise reduction component 4 is replaced. Through the arrangement of the connecting portion 32 and the fixing portion 13, on the one hand, the connection stability between the card cover component 3 and the ventilation duct 1 is increased to increase the stability of the noise reduction component 4, thereby ensuring the noise reduction effect of the noise reduction component 4. On the other hand, the card cover component 3 is easy to disassemble and assemble, so as to achieve the effect of facilitating the patient to replace the noise reduction component 4, thereby further improving the patient's usage experience.

[0122] Implementation method 2. In this implementation method, refer to Figure 8 , Fig. 9 and Fig.10 One end of the card cover component 3 is hinged to the ventilation duct 1, and the other end of the card cover component 3 is provided with a connecting portion 32. The ventilation duct 1 is provided with a fixing portion 13. The connecting portion 32 can be snapped or magnetically matched with the fixing portion 13 to fix the card cover component 3.

[0123] When replacing the noise reduction component 4, first apply force to the end of the card cover component 3 away from its own hinged end so that the connecting portion 32 is released from the clamping or magnetic engagement with the fixing portion 13, and then continue to apply force to the end of the card cover component 3 away from its own hinged end so that the card cover component 3 rotates around its own hinged end, thereby exposing the noise reduction component 4 to the outside of the ventilation duct 1, and then the noise reduction component 4 can be replaced; since one end of the card cover component 3 is hinged to the ventilation duct 1, and then when the card cover component 3 rotates to expose the noise reduction component 4 to the outside of the ventilation duct 1, the card cover component 3 is still connected to the ventilation duct 1, so as to avoid the possibility of loss of the card cover component 3 when replacing the noise reduction component 4, and when the patient replaces the noise reduction component 4, he only needs to operate the end of the card cover component 3 away from its own hinged end, so as to further reduce the difficulty of replacing the noise reduction component 4, so as to further improve the patient's replacement efficiency of the noise reduction component 4, and thereby further improve the patient's use experience.

[0124] Implementation method 3. In this implementation method, refer to Fig.11 and Fig.12The card cover component 3 includes a first cover body 33 and a second cover body 34 which are arranged opposite to each other. A connecting portion 32 is provided at one end of the first cover body 33, and a fixing portion 13 which can be snapped or magnetically matched with the connecting portion 32 is provided at one end of the second cover body 34. The other end of the first cover body 33 and the other end of the second cover body 34 are hinged to the ventilation duct 1.

[0125] When replacing the noise reduction component 4, first apply a force in the direction of moving away from each other to the ends of the first cover body 33 and the second cover body 34 away from the hinged end, so that the connecting portion 32 and the fixing portion 13 are released from the snap connection or magnetic attraction, and then continue to rotate the first cover body 33 and the second cover body 34, so that the noise reduction component 4 is exposed to the outside of the ventilation duct 1, and then the noise reduction component 4 can be replaced; since one end of the first cover body 33 and the second cover body 34 are both hinged to the ventilation duct 1, and then when the first cover body 33 and the second cover body 34 are rotated to expose the noise reduction component 4 to the outside of the ventilation duct 1, the first cover body 33 and the second cover body 34 are still connected to the ventilation duct 1, thereby avoiding the phenomenon that the card cover component 3 is easily lost when the noise reduction component 4 is replaced, thereby improving the patient's use experience; at the same time, when opening the card cover component 3, it is only necessary to operate the connection between the first cover body 33 and the second cover body 34 to reduce the difficulty of replacing the noise reduction component 4.

[0126] Embodiment 4: In this embodiment, referring to Fig.13 The card cover component 3 includes a first cover body 33 and a second cover body 34 which are arranged opposite to each other. A connecting portion 32 is provided at one end of the first cover body 33, and a fixing portion 13 which can be snapped or magnetically matched with the connecting portion 32 is provided at one end of the second cover body 34. The other end of the first cover body 33 and the other end of the second cover body 34 are hinged to each other through a connecting portion 331.

[0127] Since the other end of the first cover body 33 and the other end of the second cover body 34 are hinged to each other through the connecting portion 331, on the one hand, the difficulty of operation when replacing the noise reduction component 4 is reduced to improve the efficiency of replacing the noise reduction component 4; on the other hand, the card cover component 3 can be separated from the ventilation duct 1, so that when the noise reduction component 4 is replaced, the card cover component 3 can avoid the noise reduction component 4 to reduce the difficulty of disassembly and assembly of the noise reduction component 4, so as to further improve the replacement efficiency of the noise reduction component 4.

[0128] The present application does not specifically limit the structure of the connecting portion 331. Preferably, refer to Fig.13The connecting portion 331 is a thin-walled structure, one end of the thin-walled structure is connected to the first cover body 33, and the other end of the thin-walled structure is connected to the second cover body 34, so that the first cover body 33 and the second cover body 34 are mutually hinged through the thin-walled structure, thereby reducing the production cost of the card cover component 3, so as to reduce the production cost of the connector. In other embodiments, the connecting portion 331 can also be a connecting pin that penetrates the first cover body 33 and the second cover body 34, so that the first cover body 33 and the second cover body 34 are mutually hinged through the connecting pin.

[0129] In the above four embodiments, the structures of the connecting portion 32 and the fixing portion 13 are not specifically limited, and they may adopt any one of the following embodiments:

[0130] Embodiment 1, in this embodiment, refer to Figures 7 to 13 The fixing portion 13 is a convex structure, and the connecting portion 32 is a rib structure. The rib structure can be snap-fitted with the convex structure to achieve snap-fitting of the connecting portion 32 and the fixing portion 13, thereby utilizing snap-fitting to fix the card cover component 3, so as to increase the stability of the card cover component 3, and further ensure the noise reduction effect of the noise reduction component 4.

[0131] Embodiment 2, in this embodiment, refer to Fig.16 One of the fixing part 13 and the connecting part 32 is an iron sheet, and the other is a magnetic block. The magnetic block can cooperate with the iron sheet by magnetic attraction, so as to fix the card cover component 3 by magnetic attraction cooperation between the connecting part 32 and the fixing part 13, thereby achieving the effect of facilitating the disassembly of the card cover component 3 and facilitating the replacement of the noise reduction component 4.

[0132] Of course, in addition to the above four implementations, the cover member 3 can also be connected to the ventilation duct 1 by screw fixing or sliding.

[0133] In a preferred embodiment, referring to Figure 8 , Fig.10 and Fig.11 The ventilation duct 1 is provided with positioning ribs 14 located on both sides of the plurality of exhaust holes 21 , and the cover member 3 is located between the positioning ribs 14 to position the cover member 3 .

[0134] After the card cover component 3 is installed in the ventilation duct 1, the card cover component 3 is located between the two positioning ribs 14. On the one hand, the positioning ribs 14 can position the card cover component 3 to facilitate the installation of the card cover component 3, thereby reducing the difficulty of assembling the card cover component 3 and ensuring the fixing effect of the card cover component 3 on the noise reduction component 4. On the other hand, the positioning ribs 14 can also limit the card cover component 3 to avoid the axial movement of the card cover component 3 along the ventilation duct 1, thereby increasing the connection stability between the card cover component 3 and the ventilation duct 1.

[0135] The present application does not specifically limit the connection relationship between the noise reduction component 4 and the card cover component 3, and it can adopt any one of the following embodiments:

[0136] Embodiment 1. In this embodiment, the noise reduction component 4 is fixedly connected to the card cover component 3, thereby increasing the stability of the noise reduction component 4. At the same time, when the noise reduction component 4 is replaced, it is only necessary to remove the card cover component 3 and replace it together with the card cover component 3, so as to further achieve the effect of facilitating the replacement of the noise reduction component 4.

[0137] In the present embodiment, there is no specific limitation on the fixing method of the noise reduction component 4 and the cover component 3, and other fixing methods such as gluing, ultrasonic welding, one-piece molding with rubber coating or snap fixing can be used.

[0138] Implementation method 2. In this implementation method, refer to Figures 7 to 10 The noise reduction component 4 and the card cover component 3 are separately arranged, that is, the noise reduction component 4 and the card cover component 3 can be separated to realize the separate replacement of the noise reduction component 4, so as to reduce the replacement cost of the noise reduction component 4, thereby reducing the patient's use cost, and further improving the patient's use experience.

[0139] The present application does not specifically limit the form in which the noise reduction component 4 and the card cover component 3 are separately arranged, and any one of the following embodiments may be adopted:

[0140] Embodiment 1, in this embodiment, refer to Figure 8 and Fig. 9 The inner side of the card cover component 3 is a curved surface adapted to the outer side of the noise reduction component 4, so that the inner side of the card cover component 3 can apply an extrusion force to the noise reduction component 4 toward the ventilation duct 1, so as to utilize the extrusion of the noise reduction component 4 by the card cover component 3 to fix the noise reduction component 4.

[0141] Embodiment 2, in this embodiment, refer to Fig.10 The card cover component 3 has a supporting rib 35 , and an accommodating space 351 with an opening on the side is formed between the supporting rib 35 and the card cover component 3 , and the noise reduction component 4 is arranged in the accommodating space 351 via the opening.

[0142] Since the noise reduction component 4 is arranged in the accommodating space 351, the noise reduction component 4 can move together with the card cover component 3, so that the noise reduction component 4 can be separated from the ventilation duct 1 while the card cover component 3 is opened, so as to achieve the effect of facilitating the patient to separate the noise reduction component 4 from the ventilation duct 1; and since the side of the accommodating space 351 has an opening, when separating the noise reduction component 4 from the card cover component 3, the patient only needs to apply a pulling force to the noise reduction component 4 toward the side where the opening is located, thereby achieving the effect of facilitating the separation of the noise reduction component 4 from the card cover component 3. When installing the noise reduction component 4 into the accommodating space 351, it is only necessary to align the noise reduction component 4 with the opening of the accommodating space 351 and apply a pushing force to the noise reduction component 4 toward the accommodating space 351, so as to reduce the difficulty of installing the noise reduction component 4, thereby achieving the effect of facilitating the replacement of the noise reduction component 4.

[0143] Embodiment 3, in this embodiment, refer to Fig.11 and Fig.13 Both sides of the card cover member 3 are provided with edges 36 extending inward, and a receiving space 351 for accommodating the noise reduction member 4 is formed between the edges 36, and a supporting protrusion 361 located on the inner side of the noise reduction member 4 is provided along the edges 36.

[0144] Since both sides of the cover member are provided with edges 36 extending inward, a accommodating space 351 for accommodating the noise reduction component 4 is formed between the edges 36. After the noise reduction component 4 is installed in the accommodating space 351, the edges 36 can block the noise reduction component 4 in the axial direction of the ventilation duct 1 to increase the stability of the noise reduction component 4; and, since the edges 36 are provided with a supporting protrusion 361 located on the inner side of the noise reduction component 4, the supporting protrusion 361 can support the noise reduction component 4 so that the noise reduction component 4 stays stably in the accommodating space 351, so as to further increase the stability of the noise reduction component 4, thereby ensuring the noise reduction effect of the noise reduction component 4.

[0145] The present application does not specifically limit the structure of the noise reduction component 4. Preferably, refer to Fig. 9 and Fig.10 The noise reduction component 4 includes noise reduction cotton 41 and a support frame 42 extending continuously along the circumference of the noise reduction cotton 41. On the one hand, the support frame 42 can support the noise reduction cotton 41 to ensure the noise reduction effect of the noise reduction cotton 41, and at the same time ensure the air permeability of the noise reduction cotton 41 to ensure the exhaust efficiency of the exhaust hole 21. On the other hand, if the installation position of the noise reduction component 4 deviates from the required installation position, the existence of the support frame 42 will also cause the card cover component 3 to be unable to be installed in place, so as to remind the patient to adjust the noise reduction component 4, so that the support frame 42 can also play an anti-mistake role to ensure the installation accuracy of the noise reduction component 4, thereby ensuring the noise reduction effect of the noise reduction component 4.

[0146] In other embodiments, the noise reduction component 4 may also eliminate the design of the support frame 42 to reduce the cost of the noise reduction component 4 and reduce the cost of use for patients. Of course, the noise reduction component 4 may also be other soft porous structures, such as cotton wool.

[0147] In a preferred embodiment, the cross-sectional shape of the first connecting end is non-circular, and then when the first connecting end is connected to the patient's respiratory interface, the first connecting end can also play an anti-mistake role to ensure the accuracy of the connector installation, and at the same time can also increase the connection stability between the connector and the patient's respiratory interface to ensure the treatment effect on the patient.

[0148] The present application does not make any specific limitation on the formation method of the non-circular first connection end. Preferably, the cross-sectional shape of the ventilation duct 1 is elliptical, so that the cross-sectional shape of the first connection end is non-circular, so as to prevent the connector from being misconnected when connected to the patient's breathing interface, and improve the comfort of the patient when holding it.

[0149] In other embodiments, only the cross-sectional shape of the first connecting end may be non-circular, and the other parts of the ventilation duct 1 may be circular.

[0150] Of course, the cross-sectional shape of the first connecting end may also be other non-circular shapes, such as square, oblong, etc.

[0151] Reference Figures 14 to 17 The present application also discloses a patient breathing interface, which includes a bracket 5, a cushion assembly 6, a connector, a breathing circuit 7 and a side arm 8, wherein the bracket 5 has an inner side and an outer side opposite to the inner side; the cushion assembly 6 is connected to the bracket 5 and is located on the inner side of the bracket 5; the connector is connected to the bracket 5 and is located on the outer side of the bracket 5, that is, the first connecting end of the connector is connected to the bracket 5, and the connector is selected from any one of the connectors in the above-mentioned embodiments; the breathing circuit 7 is connected to the connector and connected to the cushion assembly 6 through the connector, that is, the second connecting end of the connector is connected to the breathing circuit 7; the side arm 8 is connected to the bracket 5, and is used to wear the patient breathing interface on the patient's face.

[0152] Since the patient breathing interface in the present application adopts the above-mentioned connector, the production difficulty of the patient breathing interface is reduced, the production efficiency of the patient breathing interface is improved, the production cost of the patient breathing interface is reduced, and the effect of facilitating the replacement of the noise reduction component 4 is achieved, thereby improving the patient's user experience.

[0153] The present application does not make any specific limitation on the connection method between the first connecting end and the bracket 5. The two can be fixedly connected, such as cylindrical connection, one-piece molding, bonding, or other fixed connection methods; or, the two can be detachably connected, such as snap fit, interference fit, or other detachable connection methods.

[0154] In a preferred embodiment, referring to Fig.15 The cushion assembly 6 includes a support member 61 connected to the bracket 5 and a sealing cover 62 arranged on the support member 61, the support member 61 has a vent hole, and the sealing cover 62 has a sealing rib 621 extending out of the vent hole, and the sealing rib 621 contacts the bracket 5, thereby increasing the sealing between the cushion assembly 6 and the bracket 5. On the one hand, it avoids the phenomenon that the gas flows out through the gap between the cushion assembly 6 and the bracket 5 due to the poor sealing between the cushion assembly 6 and the bracket 5 and generates noise, thereby reducing the noise of the patient's breathing interface to improve the patient's usage experience, and on the other hand, it improves the ventilation efficiency of the patient's breathing interface.
