Background

The trachea cannula is a technique which is widely applied to medical rescue patients and surgical anesthesia patients by inserting a special trachea catheter into the trachea of the patients through the oral cavity or the nasal cavity. The emergency intubation technique has become an important measure in the process of cardio-pulmonary resuscitation and rescue of critically ill patients accompanied with respiratory dysfunction, is one of the most widely applied, most effective and most rapid means in respiratory tract management, is a basic skill which must be mastered by medical staff, and plays a vital role in rescuing the lives of patients and reducing the fatality rate.

The trachea cannula can provide the best conditions for airway smoothness, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like. Along with the scientific and technological development, current trachea cannula can improve the success rate through visual laryngoscope, through observing trachea cannula's the position of placing from visual laryngoscope, realizes placing in place trachea cannula's accuracy.

However, in the case of emergency rescue, for example, patients with more throat secretions, hemoptysis, aspiration by mistake, or patients with complicated and special anatomical structures, the tracheal intubation can only be performed after the negative-pressure sputum suction device connected with the sputum suction tube is used for suction, which consumes more time, has a small lumen of the sputum suction tube, is difficult to fully suck, and particularly, when large foreign matters exist, the intubation time is easily delayed and the success rate of the tracheal intubation is reduced. And the oxygen supply device can not be connected during operation, so that oxygen supply to patients is difficult to ensure, and the patients are likely to suffer from brain death due to oxygen deficiency, which brings troubles for the treatment of the patients.

The existing tracheal catheter is made of hard materials and has various pore sizes, and when the outer diameter of the tracheal catheter is too thin, the jack leaks air due to poor sealing, so that the oxygen supply effect in the operation is influenced; when the outer diameter is too large, the catheter is difficult to insert or fails to insert, which affects the diagnosis and treatment process.
