Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a video laryngoscope. Background Art

[0002] Video laryngoscope is an alternative to direct laryngoscopy for airway intubation in adults and children because it improves airway safety and has fewer failed attempts and complications. At present, conventional video laryngoscopes have a camera at the end of the inspection end. In order to avoid the inspection end being compressed and deformed by the patient's mouth, which affects the camera's field of view, the inspection end of conventional video laryngoscopes usually adopts a fixed arc structure, but this structure cannot adjust the angle and length when inserted, resulting in it being unable to adapt to the throat depth of various patients and unable to meet the inspection of different positions of patients, which in turn causes some patients to feel strong discomfort when using it, and may even cause harm to the patient.

[0003] Based on this, the utility model designs a video laryngoscope to solve the above problems. Utility Model Content
