Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a headband-type adjustable nasal oxygen tube fixator. Background Technology

[0002] Nasal oxygen tubes are oxygen delivery tubes used in hospitals for patients with breathing difficulties and hypoxia. One end of the plug is inserted into the patient's nostril, and the other end is connected to an oxygen supply device. When the oxygen supply device is turned on, oxygen is inhaled into the lungs through the patient's nostrils to treat the patient. Nasal oxygen tubes are usually fixed in the patient's nasal cavity.

[0003] The utility model disclosed in patent application CN219323768U discloses a nasal oxygen tube fixing structure, which includes a nasal oxygen tube, a nasal plug, and a fixing band. The nasal plug is fitted onto the nasal oxygen tube, and a fixing band is provided on the outside of the nasal oxygen tube. The fixing band is provided with a squeezing mechanism that allows the nasal plug to make close contact with the nostril. The squeezing mechanism includes a fixing cavity, a threaded rod, and a limiting block. The fixing cavity is fixedly connected to one side of the fixing band, and the threaded rod is threadedly connected to one side of the fixing cavity. The end of the threaded rod is rotatably connected to the limiting block, which is annular in shape and has an opening on one side. The fixing cavity and the threaded rod are both made of PC, and the limiting block is made of PE. This technical solution uses limiting straps and Velcro on both sides of the fixing band to facilitate the fixation of the nasal oxygen tube.
