Anti-slip trachea cannula

Technical Field

The invention relates to the field of medical trachea cannula, in particular to an anti-slip trachea cannula.

Background

The respiratory tract is the passage through which the flow of air passes as the lungs breathe. The respiratory tract is divided into an upper part and a lower part: nose, throat and larynx are called upper respiratory tract; the trachea, bronchi and lung organs, collectively referred to as the lower respiratory tract, or tracheal tree, are becoming increasingly complex with the evolution of animals, with tracheal tubes being used in respiratory emergency management.

Tracheal intubation refers to a technique in which a special endotracheal tube is placed into the trachea through the glottis. The technology can provide optimal conditions for airway smoothness, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like. The emergency trachea intubation technique becomes an important measure in the process of rescuing patients with cardiopulmonary resuscitation and critical patients with respiratory dysfunction, 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 the management of respiratory tracts, is a basic skill which must be mastered by medical staff, and plays a vital role in rescuing the lives of the patients and reducing the fatality rate.

The in-process of using is being carried out to current trachea cannula, because the medical PVC material that the material of inserted part generally all is having certain hardness, in the face of the intubate use, lack effectual antiskid mode that falls, stability is relatively poor, because of medical personnel's operation gimmick, the difference of patient's trachea structure and the pathological change in-process tracheal local inflammation's all kinds of problems, all can lead to the intubate circumstances of falling, this in-process, the unexpected damage can appear to the trachea in the intubate, need many times to adjust, patient's uncomfortable sense has been increased.
