Background

The trachea cannula is a pipeline which communicates the respiratory tract of a human body with a circulation loop system of an anesthesia machine when an anesthesiologist performs general anesthesia operation so as to keep normal breathing and oxygen supply of a patient and input anesthetic drugs at the same time. The other function is that once sputum in the respiratory tract of a patient obstructs breathing in an operation, a sputum suction pipe can be inserted through the endotracheal tube to suck and remove accumulated sputum. The prior art endotracheal tube consists of a tube, an inflation tube and a balloon. Although the endotracheal tube is adequate for the operation of breathing and anaesthesia, the operation is very inconvenient or uncomfortable for the patient when sputum is sucked for the patient. In the general sputum suction operation, a sputum suction tube is inserted into an endotracheal tube under the state of stopping anesthesia and oxygen delivery until the end of the sputum suction tube extends out of the endotracheal tube, and in the state, the sputum suction operation time is limited firstly, and the anesthesia and normal respiration of a patient are influenced if the time is too long; moreover, when the trachea cannula is used for sputum suction, blind insertion and blind suction are generally adopted, and the sputum suction hole of the sputum suction tube is often sucked on the airway mucosa of a patient to break the airway mucosa; another disadvantage is that when the catheter is pulled out after operation, the patient needs to pull out the catheter and suck phlegm at the same time, so that the strong stimulation to the trachea of the patient is increased, and severe cough can be caused. The above disadvantages not only cause discomfort to the patient, but also affect the quality of anesthesia and even the effectiveness of the surgery, and in severe cases may lead to failure of the surgery.
