Preferably, the tee is a Y-shaped tee joint.

Preferably, all three joint pipe sections of the tee joint are of conical tubular structures or straight tubular structures, and the tee joint is of an equal-diameter tee joint or a reducing tee joint.

Preferably, the outer walls of the three joint pipe sections of the tee joint are fixedly connected with annular tables for limiting the separation of the pipe and the tee joint, and the annular tables are provided with chamfers towards the insertion direction.

Preferably, the two ends of the nasal suction head are connected through a direct connector, the direct connector is a stepped pipe, the large end of the direct connector is matched and inserted into the nasal suction head, and the small end of the direct connector is matched and inserted into one end of the oxygen delivery branch pipe.

Preferably, the nasal tip is a silicone tip.

Preferably, the surface of the nasal prong is coated with an antistatic coating.

Preferably, the antistatic coating is silica gel hand feeling oil.

Preferably, the two oxygen delivery branch pipes are sleeved with sliding sleeve buckles for converging the pipes, and the sliding sleeve buckles are of flat taper pipe structures with large upper parts and small lower parts.

Preferably, the inner diameter of the oxygen therapy main pipe is larger than the inner diameter of the oxygen therapy branch pipe.

In summary, the utility model has the following advantages:

1. the detachable reusable assembling structure is adopted, so that a new oxygen catheter or nasal suction head can be replaced for different patients, and compared with a disposable nasal oxygen catheter commonly used in the market, the detachable reusable assembling structure greatly reduces the waste of resources, saves the purchasing cost for medical institutions and saves the treatment cost for patients.

2. The silica gel suction head is used, the oxygen source joint can be more comfortable and soft through controlling the hardness of the silica gel material, the nasal suction head is contacted with skin more skin-friendly by adopting silica gel suitable for the comfortable hardness of a human body, and the experience of a patient is better; meanwhile, the silica gel material has better heat resistance, the temperature tolerance is about 160 ℃, the temperature tolerance is far higher than that of a PVC material, the silica gel material has no problem of harmful gas generated by decomposition like PVC, no peculiar smell exists, and the safety is higher.

3. Through setting up antistatic coating, can prevent on the one hand that static from producing, on the other hand makes the nose oxygen pipe have anti-dust, prevents that the surface from breeding the huge advantage that PVC such as harmful germ does not possess, has stopped the potential safety hazard of cross infection, has improved the security.
