Description

Device for establishing artificial airway on glottis

Technical Field

The utility model relates to the technical field of medical airways, in particular to an artificial airway device established on a glottis.

Background

Airway management refers to the process of establishing, implementing, removing artificial mechanical ventilation or artificial assisted ventilation in diagnosis and treatment of general anesthesia, emergency and critical patients due to the need of artificial ventilation for illness or operation. The medical actions covered are various aspects of mask ventilation, laryngeal mask ventilation, noninvasive ventilation, tracheal intubation, mechanical ventilation, ventilation treatment modes, mechanical ventilation withdrawal, ventilation tool removal and the like. The technology starts in the 20 th century and has been recently century old;

the most common way to clinically establish an artificial airway at present is by tracheal intubation and laryngeal mask:

1. the trachea cannula, the cannula body of the cannula needs to enter the airway, the balloon below the glottis needs air pressure to seal the airway, ischemic injury often occurs to the tracheal mucosa, and then infection is caused, even respiratory tract-related pneumonia (VAP) is caused;

2. laryngeal masks are also relatively popular airway tools, and have the disadvantages of weak tightness with the throat and frequent air leakage and difficult positive pressure ventilation; the airway is insufficiently isolated from the esophagus, and the gastroesophageal reflux rate is high, which is easy to cause the risk of aspiration of reflux.
