When in use, the first end of the tube body 1 is inserted into the trachea. When the tip hole 11 reaches the specified position, the cuff 2 is inflated by injecting gas through the inflation terminal 31, and the pressure gauge 32 is used to accurately evaluate the internal pressure of the cuff 2, which is convenient for actual intubation operations and avoids the problem of excessive compression of the capillaries in the tracheal mucosa by the cuff 2, thereby causing damage to the tracheal mucosa. Secondly, the cuff 2 is located between the tip hole 11 and the Murphy hole 12, so that the Murphy hole 12 can realize sputum suction operation on the tracheal position of the cuff 2 facing away from the lungs, thereby avoiding the problem of incomplete sputum adsorption due to the blockage of the cuff 2.

[0024] In the above technical solution, the inflation tube 3 of the tube body 1 is used to inject gas into the cuff 2 to expand the cuff 2 to an ideal state, isolating the lungs from the outside air. At this time, the tube body 1 is installed and the pressure gauge 32 is used to accurately evaluate the internal pressure of the cuff 2, which is convenient for the actual intubation operation and avoids the problem that the cuff 2 exerts excessive pressure on the capillaries in the tracheal mucosa, thereby causing damage to the tracheal mucosa.
