Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a nasal oxygen tube with adjustable nose plug spacing. Background Art

[0002] Nasal oxygen cannula is a medical device used to deliver oxygen to the patient's nose. It can help patients with breathing difficulties breathe more easily. Nasal oxygen cannula is a non-invasive oxygen supply method suitable for patients who need long-term home oxygen therapy or need supplemental oxygen in the hospital. The problems with traditional nasal oxygen cannula are:

[0003] Traditional nasal oxygen cannulas are often made of hard materials and lack flexibility, which may cause discomfort to patients during wearing, especially when used for a long time. The hard material will compress the nasal cavity, causing pain or other discomfort; traditional nasal oxygen cannulas are prone to accumulate bacteria during use, especially in hospital environments, where the risk of cross-infection is high. In addition, due to the lack of effective antibacterial coating, bacteria reproduce faster, increasing the probability of infection; traditional nasal oxygen cannulas with nasal branch tubes usually do not have a special adjustment mechanism, and it is difficult for medical staff to accurately adjust the position of the nasal plug, which may lead to inaccurate oxygen delivery and affect the treatment effect.

[0004] Therefore, the utility model proposes a nasal oxygen cannula with adjustable nose plug distance to solve the above problems. Utility Model Content
