Description

Technical Field

[0001] The utility model relates to the technical field of nasal catheters, and more specifically to an adjustable and fixed adjustment rope. Background Art

[0002] A nasal cannula is a slender rubber or plastic tube with holes at the top and sides that is inserted into the nasal vestibule. It is an oxygen supply tool commonly used in hospitals of all levels in China. Bilateral nasal cannulas can also be used and inserted into the vestibules of both nostrils at the same time. It has good compliance, is inserted shallowly, and is easily accepted by patients.

[0003] There are two common ways to wear a nasal cannula. One is to pass the nasal cannula around the back of the patient's ears and secure it with a buckle from the front of the head. The other is to pass the nasal cannula directly around the back of the patient's head and secure it with a buckle from the back of the head.

[0004] In order to prevent the nasal cannula from falling off, the first wearing method needs the buckle to be close to the patient's neck. In order to prevent the nasal cannula from falling off, the second wearing method needs the buckle to be close to the head. Both wearing methods are less comfortable. In order to prevent the nasal cannula from falling off, the nasal cannula can also be supported by a tether. However, the traditional rope cannot be adjusted at will after being fixed, and cannot meet the usage needs of different patients. Utility Model Content
