[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-2 The present invention provides a technical solution: a nasal oxygen tube for children that is easy to fix, including a nasal oxygen cannula 4, and a fixing structure 1 is provided on one side of the nasal oxygen cannula 4;

[0028] The fixing structure 1 includes a support part 12, which is disposed on one side of the outer surface of the nasal oxygen cannula 4. The bottom of the support part 12 is provided with a fixing buckle 11 for fixing the nasal oxygen cannula 4. The support part 12 is symmetrically provided with breathable adhesive parts 14 on both sides. Specifically, the breathable adhesive part 14 is 15mm long and 5mm wide, which is convenient for bonding to the upper lip of children. A hydrocolloid dressing 13 is provided on one side of the breathable adhesive part 14.

[0029] When using this device, first insert the nasal oxygen cannula 4 into the child's nasal cavity, then peel off the film on the hydrocolloid dressing 13, and then attach the hydrocolloid dressing 13 on the breathable adhesive portions 14 on both sides to the child's upper lip.

[0030] The hydrocolloid dressing 13 has the ability to absorb exudate. When there is excessive respiratory secretion, the hydrocolloid dressing 13 absorbs the exudate. The hydrophilic particles in the hydrocolloid dressing 13 can form a semi-solid substance similar to a gel, which adheres to the skin of the upper lip. At the same time, it is sticky, so it is not easy to fall off and has good adhesion stability. This avoids the problem of skin damage caused by the loosening and repeated application of adhesive tape.

[0031] As a specific embodiment of this application, please refer to Figure 3 The nasal oxygen cannula 4 is also provided with an adjustable collar 3 on one side. The collar 3 is provided with an ear hook structure 2. The ear hook structure 2 includes a posterior ear fixing part 21, which is set on the collar 3. An elastically deformable upper ear locking part 23 is provided on one side of the posterior ear fixing part 21, and an external ear fixing part 24 is provided on one side of the upper ear locking part 23. It can be fixed to the entire ear of the child with good stability and does not require the use of medical tape for bonding.

[0032] After the nasal oxygen cannula is fixed, the position of the ear hook structure 2 is adjusted by the collar 3, and then the back ear fixing part 21 is attached to the back of the child's ear. At the same time, the elasticity of the upper ear clip part 23 is used to clip it onto the upper side of the child's ear, and then the outer ear fixing part 24 is attached to the front of the child's ear. In this way, the nasal oxygen cannula 4 is fixed to the child's ear, which changes the way of adhesive tape and provides good stability.

[0033] Furthermore, an inner ear fixation part 22 is also provided on one side of the outer ear fixation part 24 to fix the child's cochlea. It can be positioned with the child's cochlea. When the outer ear fixation part 24 is attached to the child's front ear, the inner ear fixation part 22 is attached to the external auditory canal, which further improves the stability of the device when worn.

[0034] Furthermore, a silicone cochlear clip 231 is provided on one side of the inner ear fixation part 22, which can be fixed to the child's cochlea to prevent the device from becoming loose.

[0035] As a specific embodiment of this application, please refer to Figures 4-7 A rotating shaft 227 is provided on one side of the inner ear fixing part 22. The rotating shaft 227 is rotatably mounted in the support base 228. The support base 228 is movably mounted in the mounting groove 224. The mounting groove 224 is located on one side surface of the horizontal slider 223. The horizontal slider 223 is movably mounted in the horizontal slide groove 221. The horizontal slide groove 221 is located on one side of the inner surface of the outer ear fixing part 24. This allows the inner ear fixing part 22 to rotate, making it easy to adjust according to the child's ear size. Positioning buckles 226 are provided on both sides of the rotating shaft 227. The positioning buckles 226 are snapped into the positioning frame 225. The positioning frame 225 is located on both sides of the mounting groove 224, which can position the angle of the rotating shaft 227.

[0036] This application allows adjustment of the angle and position of the inner ear fixing part 22 depending on whether the left or right ear is fixed. When the left ear needs to be fixed, pulling the inner ear fixing part 22 causes the inner ear fixing plate to move the rotating shaft 227 upward. The rotating shaft 227 simultaneously moves the support base 228 and the positioning buckle 226, causing the positioning buckle 226 to move out of the positioning frame 225. Then, rotating the inner ear fixing part 22 causes the rotating shaft 227 to rotate on the support base 228, rotating the inner ear fixing part 22 180 degrees. Finally, pushing the inner ear fixing part 22 downward... The inner ear fixing part 22 drives the rotating shaft 227 to move downward, and the positioning buckle 226 is locked into the positioning frame 225, completing the adjustment of the inner ear fixing part 22. Then, push the inner ear fixing part 22, and the inner ear fixing part 22 drives the horizontal slider 223 to move in the horizontal slide groove 221, and moves the inner ear fixing part 22 to the other side of the outer fixing part. Then, the inner fixing part is locked into the child's left ear. Similarly, when fixing the right ear, the inner ear fixing part 22 is reset and rotated, and the inner ear fixing part 22 is reset and moved to the side of the outer ear fixing part 24.

[0037] Furthermore, a reset spring 222 is provided on one side surface of the mounting groove 224. One end of the reset spring 222 is connected to the support base 228. When the rotating shaft 227 drives the support base 228 to move, the support base 228 stretches the reset spring 222. Under the elastic force of the reset spring 222, the support base 228 can be reset and moved, and the positioning buckle 226 can be automatically locked into the positioning frame 225.

[0038] Furthermore, limiting blocks 230 are provided on both sides of the transverse slider 223. The limiting blocks 230 are slidably disposed in the limiting groove 229. The limiting groove 229 is symmetrically disposed on both sides of the transverse slide groove 221. When the transverse slider 223 moves, it drives the limiting blocks 230 to move in the limiting groove 229, thereby improving the movement guidance of the transverse slider 223.

[0039] Furthermore, magnetic strips 232 are embedded on both sides of the transverse slide groove 221. The magnetic strips 232 are used to attract and fix the transverse slider 223. When the transverse slider 223 moves to one side of the transverse slide groove 221, the magnetic strips 232 attract and fix the transverse slider 223.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
