Description

Technical Field

[0001] The utility model relates to the technical field of fixers, in particular to a disposable nasotracheal intubation fixer. Background Art

[0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory suction and prevention of aspiration. In oral and maxillofacial surgeries, nasotracheal intubation is required to expose the surgical area. At the same time, the endotracheal tube needs to be fixed in different directions according to the surgical site to avoid affecting the surgical operation.

[0003] However, the existing nasotracheal intubation still has the following problems when being fixed:

[0004] The endotracheal tube needs to be bent in different directions according to the different surgical sites, which will often pull the nose. If the pulling force is too strong or the time is too long, it may cause nasal damage to the patient or the endotracheal tube may come out.

[0005] Currently, most hospitals use conventional catheters rather than special-shaped tubes. Special-shaped tubes cannot adjust the bending position and direction, have a large fixing range, and many fixing layers, which will occupy more surgical and disinfection areas and are not convenient to use.

[0006] In view of the above problems, the utility model document proposes a disposable nasotracheal tube fixer. Utility Model Content
