[0024] The present utility model will be further described below in conjunction with the drawings and detailed embodiments.

[0025] Embodiment 1:

[0026] Refer to Figures 1 to 4, Embodiment 1 provides an improved pediatric nasal oxygen catheter, which includes an oxygen inhalation tube. The oxygen inhalation tube includes a first catheter 1, two second catheters 2 respectively connected to the ends of the first catheter 1, and two nasal cannulas 3 conductively arranged on the second catheters 2. The first catheter 1 bulges upward to form an arc-shaped structure, and the first catheter 1 can abut against the nose. The nasal cannulas 3 bend downward and can be inserted into the nostrils. A first buffer portion 4 capable of abutting against the nose is provided at the bottom of the first catheter 1, and a second buffer portion 5 capable of abutting against the face is provided on the second catheter 2. The first buffer portion 4 and the second buffer portion 5 can be fixed by medical adhesive tape. Each nasal cannula 3 is provided with a first strengthening portion 6. The first strengthening portion 6 is a strip-shaped structure and is arranged along the length direction of the nasal cannula 3. Two break openings 60 are provided on the first strengthening portion 6. The two break openings 60 are respectively located in the upper and lower parts of the nasal cannula 3, and the length of the break opening 60 is 1 mm. A second strengthening portion 7 is provided at the connection between the first catheter 1 and the second catheter 2.

[0027] The length of the above-mentioned break opening 60 is usually set to 0.5 mm to 3 mm, and it can also be other lengths, which are specifically set according to the situation.

[0028] The number of the above-mentioned break openings 60 can be one, two, three or even more, and the above-mentioned break openings 60 can also not be provided, which are specifically set according to the situation.

[0029] The number of the above-mentioned nasal cannulas 3 can also be one, and only one nostril is supplied with oxygen, which is specifically set according to the situation.

[0030] The above-mentioned first strengthening portion 6 can also be spirally arranged on the outer surface of the nasal cannula 3, which can not only enhance the strength of the nasal cannula 3, but also the nasal cannula 3 can be appropriately adjusted according to the situation; the above-mentioned first strengthening portion 6 can also be wavy, V-shaped, irregularly shaped or other shapes, which are specifically set according to the situation.

[0031] The above-mentioned second strengthening portion 7 can also not be provided, which is specifically set according to the situation.

[0032] The above-mentioned first buffer portion 4 and second buffer portion 5 are made of silica gel material, and can also be made of rubber or other soft materials, which are specifically set according to the situation.

[0033] The above-mentioned nasal cannula 3 is an n-shaped structure, and can also be an arc-shaped structure or other structures, which are specifically set according to the situation.

[0034] The working mode of Embodiment 1 is:

[0035] The first buffer part 4 abuts against the human nose, and the two second buffer parts 5 are respectively located on the face on both sides of the nose. After adjusting the positions of the first catheter 1, the second catheter 2 and the nasal cannula 3, the first buffer part 4 and the second buffer part 5 are fixed on the face of the child through medical adhesive tape, and then the oxygen inhalation tube is finely adjusted. The oxygen inhalation tube does not pass between the mouth and the nose, and the fixing and buffering effects are good. When the oxygen inhalation tube is used for a long time, a traditional oxygen inhalation tube can be used for replacement and used alternately with the traditional oxygen inhalation tube to improve the comfort of the child.

[0036] Embodiment 2:

[0037] Reference Figures 1 to 5 , the main difference between Embodiment 2 and Embodiment 1 is that: a sweat absorption layer 8 is provided at the bottom of the first buffer part 4 and the second buffer part 5 in Embodiment 2.
