Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0027] Embodiment 1

[0028] Please see Figures 1-5 , the embodiment provides a nasal high-flow nasal oxygen tube, which comprises an oxygen supply pipe 1 for connecting with a gas supply end, a nasal plug pipe 2 in communication with the oxygen supply pipe 1 and a nasal plug 3 arranged on the nasal plug pipe 2, the nasal plug pipe 2 is in a cylindrical shape, and an adjusting sleeve 4 is arranged on the outer side of the nasal plug pipe 2; the bottom end of the adjusting sleeve 4 is provided with a contact plate 41 which is in close contact with the skin of the human body; the nasal plug pipe 2 is rotatably connected with the adjusting sleeve 4, and the side wall of the adjusting sleeve 4 is provided with an arc-shaped notch 42 matched with the nasal plug 3; when the nasal plug pipe 2 rotates circumferentially relative to the adjusting sleeve 4, the nasal plug 3 slides in the arc-shaped notch 42 along with the rotation of the nasal plug pipe 2.

[0029] It can be understood that the nasal oxygen tube structure provided by the embodiment combines the advantages of the cylindrical shape and the arc shape, the adjusting sleeve 4 is arranged on the outer side of the nasal plug pipe 2, and the nasal plug pipe 2 is rotatably arranged relative to the adjusting sleeve, so that a small amount of rotation or adjustment can be made when wearing, the bottom end of the adjusting sleeve is provided with a contact plate 4,

[0030] the contact area with the wearer is increased, so that the nasal oxygen tube provided by the embodiment can not only well adapt to the wearing needs of most people, but also reduce the discomfort caused by long-time wearing and prevent pressure injuries.

[0031] As a preferred embodiment, please see Figure 3 , the cross-sectional width of the bottom surface of the contact plate 41 which is in contact with the human body in the axial direction of the adjusting sleeve 4 is greater than the cross-sectional width of the nasal plug pipe 2, which helps to disperse the pressure of wearing and improve the comfort of wearing on the one hand. On the other hand, when the width of the contact plate 41 is greater than the width of the nasal plug pipe 2, the interference between the nasal plug pipe 2 and the adjusting sleeve 41 can be reduced, so that the nasal plug pipe 2 can rotate and adjust more smoothly in the adjusting sleeve 4 when wearing.

[0032] As a preferred embodiment, the contact plate 41 is a breathable flexible plate material, the flexible plate material is a foam dressing plate material, so that the air can flow, and the contact plate 41 can better fit the skin, adapt to different facial profiles and improve the comfort of wearing; in some embodiments of the present application, the flexible plate material can also be a polyurethane film dressing plate material, which has good waterproofness and durability while maintaining breathability; or a gauze dressing plate material, which has high breathability and softness.

[0033] As a preferred embodiment, the edge or periphery of the contact plate 41 is thickened, which can effectively prevent the edge of the contact plate 41 from being raised or curled when the nasal plug pipe is rotated, so as to improve the stability of the device and the comfort of wearing.

[0034] As a preferred embodiment, please see Figure 1 ,Figure 4 The side wall of the adjusting sleeve 4 is provided with an open groove 43, which is arranged axially along the adjusting sleeve 4. The adjusting sleeve 4 is detachably sleeved on the nasal plug tube 2 through the open groove 43, so as to provide greater flexibility, so that the wearer can replace or clean the adjusting sleeve 4 as needed without replacing the entire nasal oxygen tube device.

[0035] As a preferred embodiment, the inner diameter of the open groove 43 matches the outer diameter of the nasal plug tube 2, and the nasal plug tube 2 is rotatably arranged in the open groove 43. More specifically, the inner diameter of the open groove 43 is the same as the outer diameter of the nasal plug tube 2, so that the nasal plug tube 2 can rotate more smoothly in the open groove. In some embodiments of the present application, the inner diameter of the open groove 43 can also be slightly smaller than the outer diameter of the nasal plug tube 2, so as to reduce the gap during rotation and improve stability.

[0036] As a preferred embodiment, please refer to Figure 5 The nasal high-flow nasal oxygen tube further comprises a fixing belt 5 arranged at both ends of the adjusting sleeve 4, which is used to fix the nasal oxygen tube on the head of the patient. The fixing belt 5 comprises an elastic belt 51 and an adjusting member 52 for adjusting the tightness of the wearing. In the present embodiment, the adjusting member 52 can be a buckle, and the tightness of the fixing belt can be changed by adjusting the position of the buckle. In some embodiments of the present application, the adjusting member can also be in the form of a magic tape, a clasp, a buckle, etc.

[0037] As a preferred embodiment, please refer to Figure 5 The nasal high-flow nasal oxygen tube further comprises a facial patch 6 for dispersing the pressure of the nasal fixing belt 5 on the skin and reducing the discomfort caused by long-term wearing. One end of the facial patch 6 is rotatably connected with the adjusting sleeve 4, and the other end of the facial patch 6 is connected with the elastic belt 51. In this way, the facial patch 6 is arranged so as to better follow the facial movements of the wearer during wearing, thereby improving the wearing comfort.

The oxygen tube fixing member 7 at least comprises a tie, which can be used to be fixed at the neck of the wearer, so as to prevent the oxygen tube 1 from moving or twisting during wearing, thereby reducing the risk of accidental falling or being pulled of the oxygen tube 1.

[0039] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
