[0049] like Figures 1 to 14 As shown, the respiratory mask includes a headband tube assembly 10 and a cushion assembly 20.

[0050] The cushion assembly 20 includes a fixing portion 21 and a sealing portion 22. The sealing portion 22 surrounds the fixing portion 21 and is connected to the fixing portion 21. The sealing portion 22 is provided with an air inlet 221 and an opening 222. The sealing portion 22 is used to contact the patient's face, and the opening 222 is used to deliver gas to the patient's mouth and / or nose. The headband tube assembly 10 has an air inlet end and an air outlet end. The air inlet end is used to connect to a ventilation therapy device, and the air outlet end is connected to the air inlet 221. When the sealing portion 22 contacts the patient's face, the headband tube assembly 10 is located at the patient's head. The air inlet 221 and the opening 222 can be connected.

[0051] In the embodiment of the present application, since the sealing portion 22 surrounds the fixing portion 21 and is connected to the fixing portion 21, the sealing portion 22 is provided with an air inlet 221 and an opening 222, and the air inlet 221 is in communication with the opening 222, so once gas is injected through the air inlet 221, the gas can flow to the opening 222. Since the air outlet end of the headband tube assembly 10 is connected to the air inlet 221, the air inlet end of the headband tube assembly 10 can be connected to a ventilation therapy device, so that the ventilation therapy device can transfer gas to the headband tube assembly 10, the headband tube assembly 10 transfers gas to the air inlet 221, and the air inlet 221 transfers gas to the opening 222, so that when the patient wears the respiratory mask, the opening 222 can transfer gas to the patient's mouth and / or nose. In addition, the air outlet of the headband tube assembly 10 is connected to the air inlet 221 on the sealing part 22, so that when the patient wears the breathing mask, that is, when the sealing part 22 contacts the patient's face, the headband tube assembly 10 is located on the patient's head, that is, the patient can wear the headband tube assembly 10, so that the headband tube assembly 10 is located at the patient's head, so that when the patient uses the breathing mask, the patient's chest does not press the patient's pipeline, so that the patient's sleep quality is improved. That is, in the embodiment of the present application, by setting the headband tube assembly 10 to be connected to the air inlet 221 on the sealing part 22, the air inlet 221 is connected to the opening 222, so that when the patient wears the breathing mask, the headband tube assembly 10 can be worn, so that the sealing part 22 contacts the patient's face, and the headband tube assembly 10 can be connected to the ventilation treatment device, so that the patient can inhale the gas transmitted by the ventilation treatment device through the opening 222 on the sealing part 22, and the headband tube assembly 10 is located at the patient's head position, avoiding the presence of pipelines on the patient's chest, thereby improving the patient's sleep quality.

[0052] It should be noted that, in the embodiment of the present application, the opening 222 can only deliver gas to the patient's mouth, in which case the breathing mask can be an oral mask; the opening 222 can also only deliver gas to the patient's nose, in which case the breathing mask is a nasal mask; the opening 222 can also simultaneously deliver gas to the patient's mouth and nose, in which case the breathing mask is an oral-nasal mask or a full-face mask.

[0053] In addition, in the embodiment of the present application, the material of the sealing portion 22 includes, but is not limited to, relatively soft materials such as silicone, foam, gel, and fabric, and relatively hard materials such as PP and PC may also be used. Of course, the material of the sealing portion 22 may be a combination of two or more materials. For example, the portion of the sealing portion 22 that contacts the patient is made of a softer material, and the portion away from the patient is made of a harder portion. In addition, the material of the fixing portion 21 may be the same as that of the sealing portion 22. Of course, the material of the fixing portion 21 may also be different from that of the sealing portion 22, and the embodiment of the present application does not limit this.

[0054] In addition, in the embodiment of the present application, the molding method of the liner assembly 20 includes but is not limited to injection molding, cutting, 3D printing and other molding methods. Among them, the fixing part 21 and the sealing part 22 can be integrally formed. Of course, the fixing part 21 and the sealing part 22 can also be two separate parts, which are realized by buckling, bonding, welding, magnetic connection and other methods.

[0055] In addition, in the embodiment of the present application, an airflow channel may be provided in the sealing portion 22, one end of the airflow channel is connected to the air inlet 221, and the other end of the air inlet channel is connected to the opening 222, so that the air inlet 221 is connected to the opening 222. Of course, the sealing portion 22 and the opening 222 may be connected in other ways, for example, an airflow tube is provided in the sealing portion 22, and the opening 222 is connected to the air inlet 221 through the airflow tube. The embodiment of the present application does not limit the specific way in which the air inlet 221 and the opening 222 are connected.

[0056] In addition, in the embodiment of the present application, the number of the air inlets 221 can be set according to actual needs. For example, if the number of the air inlets 221 is two, then the number of the air outlets of the headband tube assembly 10 can be two. For another example, if the number of the air inlet 221 is one, then the number of the air outlets of the headband tube assembly 10 is one. The specific number of the air inlets 221 is not limited in the embodiment of the present application.

[0057] In addition, if Figure 1 , Figure 8 and Fig. 9As shown, the breathing mask can also include a safety valve sheet 30, and a mounting hole 211 and a safety valve hole 212 are provided on the fixing part 21; the safety valve sheet 30 is installed in the mounting hole 211, and at least part of the safety valve sheet 30 is located inside the fixing part 21, and the safety valve sheet 30 is movable relative to the mounting hole 211 so that the safety valve sheet 30 can switch between a first position and a second position; when the air outlet end of the headband tube assembly 10 outputs gas, the safety valve sheet 30 is located in the first position, and the safety valve sheet 30 covers the safety valve hole 212; when the air outlet end of the headband tube assembly 10 does not output gas, the safety valve sheet 30 is located in the second position, and the safety valve sheet 30 releases the cover on the safety valve hole 212.

[0058] Since the safety valve plate 30 is movable relative to the mounting hole 211 , the safety valve plate 30 can switch between the first position and the second position during the movement. Specifically, when gas is output from the air outlet end of the headband tube assembly 10, which is equivalent to the patient wearing a breathing mask, and the headband tube assembly 10 of the breathing mask is connected to the ventilation therapy device, the ventilation therapy device transmits gas to the headband tube assembly 10, and the headband tube assembly 10 transmits gas to the sealing portion 22 through the air outlet end, the valve sheet is installed in the first position, and the safety valve sheet 30 covers the safety valve hole 212, thereby preventing the gas transmitted by the ventilation therapy device from being output more from the safety valve hole 212, and less gas is transmitted to the patient's mouth and / or nose; when gas is not output from the air outlet end of the headband tube assembly 10, which is equivalent to the ventilation therapy device not being turned on, the safety valve sheet 30 is located in the second position, and the safety valve sheet 30 releases the cover on the safety valve hole 212, so that the waste gas exhaled by the patient can be transmitted from the safety valve hole 212 to the outside of the breathing mask, so that the transmission of the patient's exhaled gas to the outside of the breathing mask is not affected. That is, by providing the safety valve sheet 30, it can be ensured that when the ventilation therapy device transmits gas to the breathing mask, the patient can inhale more gas, thereby preventing the gas transmitted by the ventilation therapy device from being transmitted to the outside of the breathing mask through the safety valve hole 212. In addition, the gas transmitted by the ventilation therapy device can make the breathing mask have a certain air pressure, so that the patient can be effectively treated.

[0059] It should be noted that when the safety valve sheet 30 is in a stationary state, the safety valve sheet 30 is located in the second position. Once the ventilation therapy equipment transmits gas to the breathing mask and there is a certain air pressure in the breathing mask, the safety valve sheet 30 can be moved, that is, the safety valve sheet 30 moves from the second position to the first position, covering the safety valve hole 212.

[0060] In addition, in the embodiment of the present application, the number of the mounting holes 211 and the number of the safety valve holes 212 can be set according to actual needs. For example, the number of the mounting holes 211 is two, the number of the safety valve holes 212 is two, and one mounting hole 211 corresponds to one safety valve hole 212. For another example, the number of the mounting holes 211 is one, and the number of the safety valve hole 212 is one. The embodiment of the present application does not limit the number of the mounting holes 211 and the number of the safety valve holes 212. In addition, the number of the safety valve plates 30 can be the same as the number of the mounting holes 211. In addition, when the blocking rib 213 is provided in the safety valve hole 212, the blocking rib 213 separates the safety valve hole 212 into at least two sub-holes. At this time, the safety valve hole 212 provided with the blocking rib 213 is one safety valve hole 212, and each sub-hole in the safety valve hole 212 is not counted in the number of the safety valve holes 212.

[0061] In addition, in some embodiments, Figure 4 and Figure 8 As shown, a blocking rib 213 may be provided in the safety valve hole 212, and both ends of the blocking rib 213 are respectively connected to the hole walls of the safety valve hole 212, and the blocking rib 213 divides the safety valve hole 212 into at least two sub-holes. The blocking rib 213 is used to prevent the safety valve plate 30 from entering the safety valve hole 212 when the safety valve plate 30 is in the first position.

[0062] By providing the blocking rib 213, the blocking rib 213 can occupy the space in the safety valve hole 212, and the blocking rib 213 can separate the safety valve hole 212 into at least two sub-holes, so that once the safety valve plate 30 moves to the first position, the blocking rib 213 can block the safety valve plate 30, avoiding the problem that the safety valve plate 30 may be subjected to a large force and embedded in the safety valve hole 212, and the safety valve plate 30 is difficult to recover from the first position to the second position, thereby affecting the use of the safety valve plate 30. That is, by providing the blocking rib 213 in the safety valve hole 212, the safety valve plate 30 can be better used.

[0063] It should be noted that the number of the blocking ribs 213 can be set according to actual needs. For example, the number of the blocking ribs 213 is 1, and for another example, the number of the blocking ribs 213 is 2. The specific number of the blocking ribs 213 is not limited in the embodiment of the present application.

[0064] In addition, in some embodiments, Figure 8 or Fig. 9 As shown, the air outlet end of the headband tube assembly 10 is connected to a plug 101, and a socket 2211 is provided in the air inlet 221, and the plug 101 cooperates with the socket 2211; when the air outlet end of the headband tube assembly 10 outputs gas, the plug 101 transfers the gas to the interior of the fixed part 21.

[0065] By providing a socket 2211 in the air inlet 221, when the air outlet of the headband tube assembly 10 is connected to the plug 101, when it is necessary to connect the air outlet of the headband tube assembly 10 to the air inlet 221 on the sealing portion 22, the plug 101 can be inserted into the socket 2211 by a bracket, and the socket 2211 can fix the plug 101, thereby preventing the headband tube assembly 10 from being easily separated from the sealing portion 22. In addition, after the plug 101 is inserted into the socket 2211, the gas output from the headband tube assembly 10 can enter the plug 101, and flow to the inside of the fixing portion 21 through the plug 101, that is, by providing the plug 101, the transmission of gas from the headband tube assembly 10 to the breathing mask will not be affected.

[0066] It should be noted that the socket 2211 and the sealing part 22 can be an integrated structure, that is, the gasket assembly 20 and the socket 2211 are integrally formed. Of course, the socket 2211 can also be fixed to the air inlet 221 of the sealing part 22, wherein the socket 2211 can be fixed to the air inlet 221 of the sealing part 22 by magnetic connection, and of course, it can also be welded. The specific fixing method of the socket 2211 to the air inlet 221 of the sealing part 22 is not limited in the embodiment of the present application. Among them, the material of the socket 2211 includes but is not limited to PP, PC, nylon and other materials.

[0067] In addition, in some embodiments, Fig.14 As shown, when the air outlet of the headband tube assembly 10 does not output gas, the safety valve plate 30 is located at the second position, and the safety valve plate 30 is at least partially in contact with the end surface of the plug 101 to block the air outlet of the plug 101.

[0068] By such a configuration, when the plug 101 on the air outlet of the headband tube assembly 10 is inserted into the air inlet 221 on the sealing portion 22, the plug 101 cooperates with the socket 2211. Once the air outlet of the headband tube assembly 10 does not output gas, it indicates that the ventilation therapy device connected to the headband tube assembly 10 is not turned on, and the safety valve sheet 30 is located at the second position, and the safety valve sheet 30 fits the end surface of the plug 101, so that the safety valve sheet 30 blocks the air outlet of the plug 101, preventing the patient's exhaled waste gas from entering the air outlet, that is, preventing the patient's exhaled waste gas from entering the headband tube assembly 10. That is, by such a configuration, it can be effectively prevented that the patient's exhaled waste gas enters the headband tube assembly 10 when the ventilation therapy device is not turned on.

[0069] It should be noted that when the safety valve sheet 30 is fitted with the end surface of the plug 101, the safety valve sheet 30 and the end surface of the plug 101 may be completely fitted, and of course, the safety valve sheet 30 and the end surface of the plug 101 may only be partially fitted, that is, the safety valve sheet 30 and the end surface of the plug 101 are substantially fitted. This embodiment of the present application is not limited here.

[0070] In addition, in some embodiments, Figure 7 As shown, the safety valve sheet 30 may include a mounting portion 31, a movable portion 32 and a shielding portion 33, and the mounting portion 31, the movable portion 32 and the shielding portion 33 are connected in sequence, the mounting portion 31 is mounted on the mounting hole 211, and the shielding portion 33 is movable or deformable relative to the mounting portion 31; when the air outlet end of the headband tube assembly 10 outputs gas, the shielding portion 33 drives the movable portion 32 to move or deform, and the shielding portion 33 shields the safety valve hole 212; when the air outlet end of the headband tube assembly 10 does not output gas, the shielding portion 33 drives the movable portion 32 to return to its initial state, and the shielding portion 33 releases the shielding of the safety valve hole 212.

[0071] By such a configuration, when the safety valve sheet 30 is installed in the mounting hole 211, the mounting portion 31 can be directly installed in the mounting hole 211, so that the movable portion 32 and the shielding portion 33 are located inside the fixed portion 21, and the movable portion 32 is movable or deformable relative to the mounting portion 31, so that the shielding portion 33 can move, so that the shielding portion 33 can switch between the first position and the second position. Specifically, when the gas is output from the outlet end of the headband tube assembly 10, the air pressure inside the fixed portion 21 and the gas output from the headband tube assembly 10 drive the shielding portion 33 to move, so that the shielding portion 33 moves to the first position, so that the shielding portion 33 blocks the safety valve hole 212; when the gas is not output from the outlet end of the headband tube assembly 10, the shielding portion 33 drives the movable portion 32 to return to the initial state, the shielding portion 33 moves to the second position, and the shielding portion 33 releases the shielding of the safety valve hole 212.

[0072] It should be noted that when the safety valve sheet 30 is in contact with the end surface of the plug 101, the shielding portion 33 is in contact with the end surface of the plug 101. When the shielding portion 33 is in contact with the end surface of the plug 101, the shielding portion 33 and the end surface of the plug 101 may be completely in contact with each other. Of course, the shielding portion 33 and the end surface of the plug 101 may only be partially in contact with each other, that is, the shielding portion 33 and the end surface of the plug 101 may be substantially in contact with each other. This is not limited in the embodiments of the present application.

[0073] In addition, in the embodiment of the present application, the material of the safety valve plate 30 may include but is not limited to silicone, foam, gel, fabric and other materials, and PP, PC and other materials may also be used. Of course, the material of the safety valve plate 30 may also be formed by at least two materials, for example, the material of the movable part 32 is different from that of the mounting part 31, the movable part 32 is made of silicone material, and the mounting part 31 is made of PP material. In addition, in the embodiment of the present application, the material of the movable part 32 and the shielding part 33 may be the same, but in order to make the movable part 32 movable or deformable, the thickness of the movable part 32 may be less than the thickness of the shielding part 33. In addition, the movable part 32 may be a rotating shaft structure, or a pin structure, etc., as long as the movable part 32 can rotate so that the shielding part 33 can switch between the first position and the second position.

[0074] In addition, in some embodiments, Fig.10 As shown, the shielding portion 33 switches from the first position to the second position, or switches from the second position to the first position, and the angle of rotation of the shielding portion 33 ranges from 40° to 150°.

[0075] When the shielding part 33 switches from the first position to the second position, or switches from the second position to the first position, by setting the angle range of rotation of the shielding part 33, it can be ensured that during the process of switching between the first position and the second position, when the shielding part 33 is in the first position, the shielding part 33 can cover the safety valve hole 212.

[0076] It should be noted that the shielding portion 33 switches from the first position to the second position, or switches from the second position to the first position. Fig.10 As shown, the angle of rotation of the shielding portion 33 can be α, and α can be any value between 40° and 150°. For example, α can be 40°, and for another example, α can be 60°, and for another example, α can be 90°, and for another example, α can be 120°, and for another example, α can be 130°, and for another example, α can be 150°. The specific value of α is not limited in the embodiment of the present application. Optionally, the range of the angle of rotation of the shielding portion 33 can be 60°-90°, and in this case, α can be any value between 60°-90°.

[0078] Through such a configuration, when the headband tube assembly 10 needs to be connected to a ventilation therapy device, the connector 103 can be directly connected to the ventilation therapy device, so that the gas transmitted by the ventilation therapy device can enter the elbow 102 through the connector 103, and then enter the headband tube assembly 10 through the elbow 102, and finally the gas enters the cushion assembly 20 through the headband tube assembly 10. That is, by providing the elbow 102 and the connector 103, it is convenient to connect the headband tube assembly 10 to the ventilation therapy device, so that the ventilation therapy device transmits the gas to the breathing mask.

[0079] In addition, in some embodiments, Figure 1 As shown, a vent hole 214 is provided on the fixing portion 21, and the vent hole 214 is used to discharge the gas exhaled by the patient when the sealing portion 22 contacts the face of the patient.

[0080] By providing the vent hole 214 on the fixing part 21, once the patient wears the breathing mask, that is, the sealing part 22 contacts the patient's face, the patient's exhaled gas can be discharged to the outside of the breathing mask through the vent hole 214, thereby preventing the patient's exhaled gas from gathering in the cushion assembly 20. In addition, by providing the vent hole 214 on the fixing part 21, the path from the outside air to the patient's inlet is as short as possible, thereby improving the efficiency of gas exchange.

[0081] It should be noted that when the patient wears the breathing mask, when the headband tube assembly 10 transfers the gas transmitted by the ventilation therapy device to the cushion assembly 20, it indicates that the ventilation therapy device is in an open state, and the safety valve sheet 30 will be located in the first position, covering the safety valve hole 212. At this time, the gas exhaled by the patient is discharged from the ventilation hole 214; when the headband tube assembly 10 does not transmit gas, it indicates that the ventilation therapy device is in a closed state, and the safety valve sheet 30 will be located in the second position, releasing the cover of the safety valve hole 212. At this time, the gas exhaled by the patient can be discharged outward through the ventilation hole 214 and the safety valve hole 212.

[0082] It should be noted that the number of the vent holes 214 can be set according to actual needs, for example, the number of the vent holes 214 is 10, and for another example, the number of the vent holes 214 is 15. The aperture of the vent holes 214 can be smaller, for example, the aperture of the vent holes 214 can be 0.5 mm, and for another example, the aperture of the vent holes 214 can be 2 mm. Preferably, the aperture of the vent holes 214 can be 0.6-1.0 mm.

[0083] Of course, in the embodiment of the present application, the vent holes 214 may also be provided on the headband tube assembly 10, the elbow 102 and other components. Of course, the vent holes 214 may also be provided on the fixing portion 21, the headband tube assembly 10 and the elbow 102 at the same time, or only on the fixing portion 21, or only on the headband tube assembly 10 or the elbow 102.

The first hole 2151 has a larger diameter, which can ensure that the guide portion 41 and the retaining portion 42 of the buckle 40 are inserted. Then, by applying force to the wearing portion 43, the wearing portion 43 drives the retaining portion 42 and the guide portion 41 to move into the second hole 2152, so that the guide portion 41 is detachably connected to the hole wall of the second hole 2152, and the installation of the buckle 40 is completed. When the buckle 40 needs to be disassembled, force can be applied to the wearing portion 43, so that the retaining portion 42 and the guide portion 41 move into the first hole 2151, and the retaining portion 42 and the guide portion 41 can be taken out from the first hole 2151, and the disassembly of the buckle 40 is completed.
