Description

Strengthen fixed trachea cannula

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a strengthen fixed trachea cannula.

Background

The technology of placing a special endotracheal tube into the trachea through the glottis is called trachea intubation, and the technology can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like.

The emergency trachea cannula technology becomes an important measure in the process of cardio-pulmonary resuscitation and emergency treatment of critically ill patients accompanied with respiratory dysfunction. The trachea intubation is an important rescue technique commonly used in emergency treatment work, is one of the most widely, effectively and quickly applied means in respiratory tract management, is the basic skill which must be mastered by medical staff, and plays a vital role in rescuing the life of a patient and reducing the fatality rate. And can in time suck out trachea incretion or foreign matter, prevent that the foreign matter from getting into the respiratory track, keep the respiratory track unobstructed, carry out effectual manual work or mechanical ventilation, prevent that patient's oxygen deficiency and carbon dioxide from lingering in the trachea cannula, whether in time direct relation rescue success is in time gone into, whether the patient can transport safely and patient's prognosis condition.

In the use process of the existing trachea cannula, the trachea cannula is fixed only by an adhesive tape, and after the trachea cannula is fixed by the adhesive tape, the adhesive tape is easy to tear off due to the fact that the skin of the face of a person secretes grease; due to the problem of the viscosity of the adhesive tape, the adhesive tape is easy to fall off when being acted by a larger external force; the problem of self-extubation of patients is easy to occur.
