DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further describes the utility model in detail with reference to the accompanying drawings.

[0017] The utility model is introduced in detail in combination with the accompanying drawings.

[0018] When the utility model is specifically implemented, a fixing device for a high-flow nasal catheter is provided, which includes a U-shaped elastic connecting pipe 1. The middle part of the U-shaped elastic connecting pipe 1 is connected to the high-flow nasal catheter, and its open ends are respectively provided with a first nasal connecting end 2 and a second nasal connecting end 3. The end of the first nasal connecting end 2 is wrapped with a first nasal cavity protection layer 4, and the end of the second nasal connecting end 3 is wrapped with a second nasal cavity protection layer 5;

[0019] A fixing plate 12 is arranged at the connection part of the U-shaped elastic connecting pipe 1 and the high-flow nasal catheter, and a strap device with adjustable tightness is connected to the fixing plate 12.

[0020] Embodiment 1:

[0021] As Figure 1 shown, the first connecting strap 8 and the second connecting strap 9 are bonded by a magic tape 10 to realize the adjustment of the tightness. Figure 1At position A in the figure is a high-flow nasal cannula.

[0022] When the utility model is in use, the first nasal connection end 2 and the second nasal connection end 3 on the U-shaped elastic connecting tube 1 are respectively connected to the nasal cavity. Among them, a first nasal cavity protection layer 4 is wrapped at the end of the first nasal connection end 2, and a second nasal cavity protection layer 5 is wrapped at the end of the second nasal connection end 3; the first nasal cavity protection layer 4 and the second nasal cavity protection layer 5 are in contact connection with the inside of the patient's nasal cavity, so as to play a protective role for the inside of the patient's nasal cavity, prevent the phenomenon of ulceration inside the patient's nasal cavity when using the high-flow nasal cannula, and improve the comfort of the patient when using the high-flow nasal cannula.

[0023] Since the U-shaped elastic connecting tube 1 has elasticity, the size of the U-shaped elastic connecting tube 1 can be adjusted as needed, so as to be adapted to the patient's nasal cavity, and the flexibility is relatively high. Moreover, the U-shaped elastic connecting tube 1 can also play a supporting role during use, avoiding the long-term wearing of the high-flow nasal cannula from rubbing against the area above the patient's lips, preventing the phenomenon of skin ulceration above the patient's lips when using the high-flow nasal cannula, and improving the comfort of the patient when using the high-flow nasal cannula.

[0024] After the U-shaped elastic connecting tube 1 is connected to the nasal cavity, it is directly fixed on the patient's head by using the first connecting strap 8 and the second connecting strap 9. During the binding process, the tightness can be directly adjusted through the magic tape, so as to be adapted to the patient's head circumference.
