[0002] Nasal oxygen cannula is a medical product made of soft polyvinyl chloride and silicone rubber. It can be used for human body to breathe oxygen after being connected to the oxygen supply system. According to different types and structures, nasal oxygen cannula can be divided into double nose type, head ring type, ear ring type, single nose type, pediatric type, infant type, etc. When using, first open the small package, connect the nasal oxygen cannula to the oxygen inhalation system, then hang the head ring or ear ring on the head or ear, and then insert the nasal plug into the nostril to breathe oxygen.

[0003] In traditional nasal oxygen cannulas, the depth at which the cotton tip and vertical tube of the nasal cannula are inserted into the patient's nasal cavity cannot be adjusted, which can easily cause discomfort to the patient and can easily cause the cannula to fall off during use, thus posing certain disadvantages.
