Background

A tracheotomy tube, called a tracheotomy tube for short, is a medical instrument implanted into the trachea of a patient through a tracheotomy opening of the neck in the tracheotomy. The purpose of implanting the tracheal cannula after tracheotomy is to keep the open state of the airway, and can carry out mechanical auxiliary ventilation and remove the endocrine of the airway in time. Clinically, with the plastic tracheotomy tube commonly used in the market at present, the patient wearing the tracheotomy tube after tracheotomy often has saliva and other secretions to overflow through the skin incision (namely, the tracheotomy) around the tracheotomy tube, which affects the healing of the skin wound, especially for the patient with long tracheotomy time, because the tracheotomy sinus is formed, the saliva overflowing from the incision is increased, the tracheotomy gauze pad is frequently required to be repeatedly replaced, otherwise, the problem that the tracheotomy skin of the patient is extremely easy to ulcer and infection, and the workload of medical care is increased is caused. In addition, an tracheostomy cannula implanted in the trachea may also cause the tracheostomy cannula to be pulled out of the trachea due to the patient coughing vigorously, causing the patient to die asphyxiatively.

The existing solution is to add a subglottic suction small tube above the air bag of the tracheostomy tube, and to remove the secretion by a negative pressure suction device (publication No. CN203915706U, application No. 201420312604.5). However, the subglottic suction small tube is often blocked by saliva, sputum scab and the like, so that a new tracheostomy cannula has to be replaced, which not only wastes medical data and increases the medical care workload, but also increases the pain of patients. The existing method for preventing the escape of the tracheostomy cannula is to press the tracheostomy cannula to prevent the escape when a patient coughs, but the method still cannot relieve the risk of the escape of the tracheostomy cannula caused by sudden coughs when the patient sleeps.
