The surface of the air release chamber 3 is evenly provided with air release holes 10. The nose pad 9 is bonded to the other side surface of the main body 1, and the surface of the nose pad 9 is provided with a water-absorbing cotton strip 11. The air guide port 7 is opened under the nose pad 9 at the middle position of the air distribution cavity 5, and the position of the side wall of the mask body 1 is fixed by fixing The piece 8 is wound and connected with the fixing belt 2 .

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , the nose pad 9 is a triangular structure, and the surface of the nose pad 9 is evenly provided with a plurality of water-absorbing cotton strips 11 , the nose pad 9 is provided with two, and the two nose pads 9 The mask body 1 is symmetrical with respect to the horizontal midline. The nose pad 9 can fit the patient's nose alar to prevent the skin from directly contacting the plastic mask. The air distribution chamber 5 has a triangular structure, and the sides of the triangular air distribution chamber 5 are arc-shaped structures. The edges and corners of 5 are provided with communication pipes 4, so that the communication pipes 4 can be introduced into the air distribution cavity 5 in multiple ways, so as to improve the uniformity of dispersion. The surface of the air vent cavity 3 is beneficial to improve the ventilation of the mask body 1 and avoid hard contact with the skin. There are two fixing pieces 8 in total, and the two fixing pieces 8 are symmetrical about the horizontal midline of the mask body 1. A fixed belt 2 is wound and connected between the two, the connecting pipe 6 is communicated with the air guide port 7 through the air dividing cavity 5, and the end of the connecting pipe 6 is communicated with the CPAP or the bi-level respiratory therapy apparatus, which is convenient for introducing oxygen to implement oxygen supply, and the edge of the mask body 1 is located It is at the same height as the deflation chamber 3 to prevent the mask body 1 from covering the deflation chamber 3, causing the deflation chamber 3 to lose its function of exhausting. The inner surface of the mask body 1 is a raised curved surface, so that the mask body 1 can fit the patient's face. The skin adopts the oxygen penetration method of the air separation chamber 5 and the air deflation chamber 3, which can give the mask an inflatable permeability effect, and can also provide sufficient oxygen when the air inside the mask body 1 is full.
