Description

A tracheal intubation device for preventing nosocomial infection

technical field

The utility model belongs to the technical field of medical devices, in particular to a tracheal intubation device for preventing nosocomial infection.

Background technique

Tracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis, which is called tracheal intubation. .

In clinical practice, many patients need endotracheal intubation. The existing endotracheal intubation devices include a ventilator and an intake intubation.
