[0054] Embodiment 3

[0055] Reference Figure 1 、 Figure 2 、 Figure 5 , the main body 1 of the present utility model will be described in detail.

[0056] In this case, wing plates 11 are symmetrically arranged on the left and right sides of the main body 1. The rear end surfaces of a pair of wing plates 11 and the rear end surface of the main body 1 together form an arc-shaped fitting surface 12, and the arc-shaped fitting surface 12 fits with the philtrum of the human body; the connection position of the connection terminal 22 and the main body 1 is further preferably on the wing plate 11.

[0057] As a further solution, a skin-friendly member 13 is arranged on the fitting surface 12; the skin-friendly member 13 is in a sheet shape, and the material can be selected from materials that can make the human body feel comfortable, such as silica gel, cotton, linen, silk, nylon, etc.

[0058] There are various ways to fix the skin-friendly member 13 on the fitting surface 12, such as bonding (Velcro), snap connection, gluing, bolt connection, etc.

[0059] Embodiment 4

[0060] Reference Figure 1 、 Figure 2 、 Figure 5 , the air supply method in the present utility model will be described in detail.

[0061] In the prior art, in order to prevent the outside air from entering the nasal cavity, the length of the air supply pipe 16 is set to be relatively large, and the outer wall of the air supply pipe 16 is attached to the inner wall of the nasal cavity to achieve sealing. However, when the air supply pipe 16 is relatively long, the patient will have a foreign body sensation, poor comfort, and skin ulceration is likely to occur after long-term wearing.

[0062] The present utility model is provided with two air supply pipes 16 and a sealing member 15. In this way, the nostrils are closed by the sealing member 15 to ensure that the outside gas does not enter the nasal cavity, so that the length of the air supply pipe 16 can be reduced.

[0063] The lower ends of a pair of air supply pipes 16 are both connected to the sealing member 15. A connecting pipe 14 is arranged at the lower end of the sealing member 15, and the lower end of the connecting pipe 14 is fixed to the main body 1 and communicated with the main body 1.

[0064] One gas delivery solution is that the gas enters the connecting pipe 14 through the main body 1, then the gas is sent into the seal 15 through the connecting pipe 14, and finally the gas is sent into the gas delivery pipe 16 through the seal 15.

[0065] Another gas delivery solution is to set two connecting pipes 14, and the two connecting pipes 14 respectively correspond to two gas delivery pipes 16; the gas enters one of the connecting pipes 14 through the main body 1, and then directly enters the corresponding gas delivery pipe 16 through the connecting pipe 14.
