Description

Technical Field

[0001] The invention discloses a nasal oxygen tube, belonging to the technical field of medical equipment. Background Art

[0002] In clinical medicine, oxygen delivery is one of the most basic nursing tasks, especially for patients receiving respiratory therapy, who often need oxygen delivery to assist in treatment. When patients breathe oxygen, oxygen is generally delivered to the patient's nasal cavity through an oxygen mask or nasal oxygen cannula. Due to the high price of oxygen masks, nasal oxygen cannula can basically meet the patient's oxygen breathing requirements in most cases.

[0003] When using nasal oxygen cannulas, they can be further divided into ear-hook type and head-mounted type according to the fixing method. Due to the different head circumferences of patients, both ear-hook type and head-mounted type generally adopt a length-adjustable design. Currently, there are several schemes for adjustable nasal oxygen cannulas: Scheme (1): Adjustment is achieved through buckles (clip), such as the technical scheme disclosed in the Chinese utility model patent with application number 01244291.7, application date August 7, 2001, and patent name "Ear-hook type oxygen inhalation cannulas", and the technical scheme disclosed in the Chinese utility model patent with application number 201720958699.1, application date July 26, 2017, and patent name "A nasal oxygen cannulas". The disadvantage of this method is that it is easy to get loose after adjustment, so it needs to be adjusted frequently, which is inconvenient to use.

[0004] Solution (2): Adjustment is achieved through an adjustment buckle, such as the technical solution disclosed in the Chinese utility model patent with application number 202022289107.6, application date October 14, 2020, and patent name "A nasal plug device for oxygen inhalation". The defect of this solution is that both ends of the elastic rope are fixed, so it is inconvenient to replace.

[0005] Solution (3) uses Velcro or buttonholes to achieve adjustment, which has similar problems as the above solution (2). In addition, due to the popularity of home oxygen concentrators, nasal oxygen tubes can generally be used for a long time after disinfection when used at home. Therefore, the design solutions of solution (2) and solution (3) are not conducive to the replacement of elastic ropes and are difficult to use for a long time.

[0006] Therefore, designing a technical solution that is convenient for length adjustment and replacement of the elastic rope when the elastic force of the elastic rope decreases has become an urgent problem to be solved in the field. At the same time, the applicant of this application also hopes to design a nasal oxygen cannula with a new structure. Utility Model Content
