[0060] The utility model will be further described below in conjunction with the accompanying drawings.

[0061] Example 1

[0062] like Figure 1-Figure 4 As shown, the utility model provides a cushion assembly 1, including a flexible unit 11 and a rigid unit 12, the flexible unit 11 and the rigid unit 12 form a breathing chamber 13 (such as Figure 3 As shown), the breathing chamber 13 and the connection hole 123 on the rigid unit 12 (as shown Figure 1 The breathing gas is input into the breathing chamber 13 through the connection hole 123 on the rigid unit 12 for use by the patient.

[0063] like Figure 1 and Figure 2 As shown, the flexible unit 11 includes a face contact portion 111 and a face support portion 112. The face contact portion 111 is used to contact the patient's face, and is therefore the softest portion of the cushion assembly 1. The face support portion 112 is used for transitional support between the face contact portion 111 and the rigid unit 12, and therefore the rigidity of the face support portion 112 is greater than that of the face contact portion 111, and less than that of the rigid unit 12.

[0064] Specifically, the hardness of the face support portion 112 is greater than the hardness of the face contact portion 111, and less than the hardness of the rigid unit 12. Since the face support portion 112 is a supporting portion between the face contact portion 111 and the rigid unit 12, it cannot be too hard, otherwise when the sealing pressure is applied to the face, the facial stress on the face contact portion 111 is too large, which may cause adverse reactions such as pressure injuries and pressure sores; but it cannot be too soft, otherwise when the sealing pressure is applied to the face, the face contact portion 111 will collapse due to insufficient support force, and the sealing will fail. Therefore, the hardness of the face support portion 112 should be higher than the hardness of the face contact portion 111, and less than the hardness of the rigid unit 12.

[0065] The facial contact portion 111 is made of a flexible and breathable material, which is configured to be deformable when in contact with the patient's face to adapt to the patient's facial shape features, thereby forming a seal with the patient's face and absorbing the patient's sweat and sebum secretions, thereby improving wearing comfort.

[0066] For example, the face contact portion 111 may be made of sponge, foam, foam or non-woven fabric, etc. Alternatively, the face contact portion 111 may also be made of a composite material.

[0067] The rigid unit 12 may be made of a thermoplastic material, for example, polycarbonate (PC), polypropylene (PP) or nylon.

[0068] Preferably, the face supporting portion 112 may be made of a sponge material having a higher hardness than the face contacting portion 111 .

[0069] Secondly, preferably, the face support part 112 can be made of a gel material. Optionally, the face support part 112 can also be made of foam, silicone rubber or composite foam.

[0070] like Figure 3As shown, the area where the face contact portion 111 contacts the patient's face may include: a nose bridge contact area 101, a cheek contact area 102, and a lip contact area 103. The nose bridge contact area 101, the cheek contact area 102, the lip contact area 103, and the cheek contact area 102 are sequentially connected end to end in the circumferential direction to form a ring-like structure.

[0071] The cushion assembly 1 of the present invention can be applied to a respiratory mask, which may be, for example, a nasal mask, a full-face mask, a nasal pad mask, etc. When the cushion assembly 1 is applied to a nasal mask, the lip contact area 103 contacts the area between the patient's upper lip and nostrils; when the cushion assembly 1 is applied to a full-face mask, the lip contact area 103 contacts the patient's chin area below the lower lip.

[0072] Since the nose bridge area and upper and lower lip areas of the patient are stress-sensitive areas, the respiratory mask should reduce the compressive stress on the stress-sensitive areas when worn. Optionally, the thickness of the material of the nose bridge contact area 101 and the lip contact area 103 can be reduced, and the contact area of ​​the material can be increased. In addition, the thickness of the material of the cheek contact area 102 can also be increased to provide more stable support and sealing.

[0073] Preferably, a stress reduction curve can be set to reduce the compressive stress on the force-sensitive area. Specifically, Figure 4 As shown, the face contact portion 111 includes a first contour curve 114 and a second contour curve 115 extending toward each other, and the first contour curve 114 and the second contour curve 115 intersect at an intersection 116, so the axial cross section of the face contact portion 111 is configured to have an approximately pointed shape. The intersection 116 is the most outwardly protruding portion of the face contact portion 111, so it can be understood that when worn, the intersection 116 contacts the patient's face for the first time, thereby forming a better sealing effect.

[0074] The angle α between the tangent line L1 of the intersection 116 and the symmetry axis of the face contact portion 111 is 45°-60°. The symmetry axis of the face contact portion 111 corresponds to the central axis of the patient's face. When the angle α is less than 45°, the contact area between the face contact portion 111 and the patient's face will decrease, so the compressive stress will increase accordingly, causing the patient's face to feel more squeezed. On the contrary, when the angle α is greater than 60°, the sealing ability of the intersection 116 will weaken, and the change or movement of the patient's face shape will easily cause the seal to fail, so that the face contact portion 111 requires a greater pressure to maintain the seal. Therefore, setting the angle α to 45°-60° can reduce the compressive stress and alleviate the patient's facial squeeze, and can also maintain the required sealing performance without too much pressure.

[0075] like Figure 2 and Figure 4As shown, the face contact portion 111 and the face support portion 112 may be connected via a flexible connection portion 113. Alternatively, the face contact portion 111 and the face support portion 112 may also be connected via ultrasonic welding, bonding or heat pressing.

[0076] like Figure 2 and Figure 4 As shown, in this embodiment 1, the flexible connection portion 113 has a planar structure. That is, the surface connecting the face contact portion 111 and the face support portion 112 is a plane.

[0077] The face contact portion 111 and the face support portion 112 may also be constructed as an integral injection molding structure or a secondary injection molding structure, that is, the face contact portion 111 and the face support portion 112 and the flexible connection portion 113 may be formed integrally.

[0078] Optionally, the rigid unit 12 and the face support portion 112 are constructed as an integral injection molding structure or a multiple injection molding structure. Alternatively, the rigid unit 12 and the face support portion 112 may be connected by ultrasonic welding, bonding or hot pressing.

[0079] In addition, the rigid unit 12 includes a chamber frame 122 , which can be directly connected to the face support portion 112 , and a connecting hole 123 passes through the chamber frame 122 .

[0080] Example 2

[0081] like Figure 5 As shown, the difference between this embodiment 2 and the above-mentioned embodiment 1 is that the flexible connection portion 113 has a convex structure and a concave structure. The convex structure and the concave structure can be arranged alternately, thereby increasing the area of ​​the surface connected between the face contact portion 111 and the face support portion 112 to enhance the firmness of the connection.

[0082] The similarities between this embodiment 2 and the above-mentioned embodiment 1 will not be repeated again.

[0083] Example 3

[0084] like Figure 6 As shown, the difference between the present embodiment 3 and the above-mentioned embodiment 1 is that the flexible connecting portion 113 has a curved surface structure. That is, the surface connecting the face contact portion 111 and the face support portion 112 is a curved surface. Figure 6 As shown, the arc surface is bent toward the face supporting portion 112, or may be bent toward the face contact portion 111, which can also increase the area of ​​the surface connected between the face contact portion 111 and the face supporting portion 112 to enhance the firmness of the connection.

[0085] The similarities between this embodiment 3 and the above-mentioned embodiment 1 will not be repeated again.

[0086] Example 4

[0087] like Figure 7 As shown, the difference between this embodiment 4 and the above-mentioned embodiments 1, 2 and 3 is that the rigid unit 12 includes a frame connection portion 121, and the rigid unit 12 and the face support portion 112 can be connected through the frame connection portion 121. Furthermore, the frame connection portion 121 can have a hook-and-groove structure, and the face support portion 112 forms an interference fit with the hook-and-groove structure to enhance the firmness of the connection.

[0088] It can be understood that if the rigid unit 12 and the face support portion 112 are constructed as a one-time injection molding structure or a multiple injection molding structure, the rigid unit 12 and the face support portion 112 and the frame connection portion 121 can be formed integrally.

[0089] The chamber frame 122 of the rigid unit 12 may be connected to the frame connection portion 121 , and the connection hole 123 passes through the chamber frame 122 .

After the headband assembly (not shown) passes through the headband holes 22, the breathing mask 100 may be fixed to the patient's face and a closed chamber may be formed at the patient's nose or mouth and nose.

[0093] The frame 2 is also provided with an elbow connection hole, through which the elbow 3 can be rotatably connected to the frame 2. A pressure support device (such as a ventilator) is connected to the elbow 3 through a gas pipeline, so that appropriate pressure gas is delivered to the chamber and then enters the patient's airway.

[0094] The gas delivered to the patient can be any suitable breathing gas known in the prior art. The gas delivery pipeline can be a well-known and commonly used bellows structure hose or the like.

[0097] In the above embodiments, the flexible unit 11 and the rigid unit 12 form a breathing chamber 13 (such as Figure 3 As shown), in this embodiment, the flexible unit 11 can also form a breathing chamber 13 with at least part of the frame 2.

[0098] The inner side of the frame 2 is connected to the flexible unit 11 via a rigid connection portion 21 , wherein the rigid connection portion 21 and the flexible unit 11 may be connected by integral injection molding, gluing, slot connection, interference fit, or the like.

[0099] The upper part and both sides of the frame 2 may be provided with headband holes 22. After the headband assembly (not shown) passes through each headband hole 22, the breathing mask 100 can be fixed on the patient's face and form a closed chamber at the patient's nose or nose and mouth.

[0100] The frame 2 is also provided with an elbow connection hole, through which the elbow 3 can be rotatably connected to the frame 2. A pressure support device (such as a ventilator) is connected to the elbow 3 through a gas pipeline, so that appropriate pressure gas is delivered to the chamber and then enters the patient's airway.
