Background

The method is an important method for supporting a breathing machine and an important technical means for protecting the airway of a patient. The intubation has certain technical difficulties and can cause mechanical damage to nasal mucosa and throat of a patient. The thicker the endotracheal tube, the more difficult it is to intubate and the greater the likelihood of injury. Therefore, for those patients who may have difficulty in intubation, physicians tend to use endotracheal tubes of relatively small tube diameter. However, the diameter of the tube is too small, which brings direct consequences of large respiratory resistance, difficult sputum suction, easy blockage of the tube and difficult postoperative airway nursing. It is desirable from a respiratory support perspective to be able to insert as thick a catheter as possible into the patient.

The whole external diameter of present embedded bellows type endotracheal tube is the same, and tip and air flue friction are great during the intubate, the propelling movement of being not convenient for, only lean on behind the intubate pipe outer wall and air flue inner wall friction fixed in addition, and stability is lower.
