Visual throat

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to visual choke.

Background

Currently, the clinical way to create a breathing passage for anaesthetized patients is to use endotracheal tubes and laryngeal masks. Trachea cannula is the medical operation of inserting endotracheal tube into the trachea through upper respiratory track to ensure the unobstructed respiratory track.

However, the front end of the tracheal cannula is sharp and provided with the air bag, so that the tracheal cannula of a patient is injured by mistake, and the pressure of the air bag on the trachea can cause a series of complications.

The laryngeal mask is a ventilation tool between the tracheal cannula and the face mask, has smaller damage than the tracheal cannula and can maintain an airway, the design principle is that the shape of the mask body of the laryngeal mask is matched with the surrounding anatomical structure of the laryngeal opening to play a sealing role, and the air bag generates larger sealing pressure on the tissues around the laryngeal opening after being inflated so as to avoid generating gaps, so that the pharyngeal tissues are easy to be crushed.
