The sleeve and the base plate are plastic parts with rigidity, the rubber pad can be made of medical silica gel material and can elastically deform, the nose adhesive layer is made of medical non-woven fabric material and has flexibility, and the nose release film can be torn off.

[0046] The extracorporeal pipe segment 7 is located inside the annular rubber pad, the inner diameter of the rubber pad is smaller than the outer diameter of the extracorporeal pipe segment 7, and both the extracorporeal pipe segment 7 and the rubber pad can elastically deform, so that the nose fixing part 4 is positioned by the clamping force and friction force between the rubber pad and the extracorporeal pipe segment 7. The "positioning" mentioned here does not mean that the nose fixing part 4 cannot be moved after being fixed. When it is necessary to move the nose fixing part 4 on the extracorporeal pipe segment 7, a relatively large force needs to be applied to the nose fixing part 4 on the basis that the extracorporeal pipe segment 7 is stationary, so as to force the nose fixing part 4 to move on the extracorporeal pipe segment 7.

[0047] In the embodiment, please refer to Figure 2 It can be seen that
