Compared with directly abutting against the auxiliary pipeline 1 at the patient's oropharynx and directly applying an extrusion force to the auxiliary pipeline 1, by supporting the auxiliary pipeline 1 with the cuff 411, the patient's oropharynx first squeezes the cuff 411. Since the gas filled in the cuff 411 causes the extrusion force received by the cuff 411 to be transmitted and dispersed everywhere, and also due to the buffering effect of the gas, the extrusion force applied to the auxiliary pipeline 1 is reduced, the deformation amount of the auxiliary pipeline 1 is reduced, so that the auxiliary pipeline 1 can maintain its original shape, and then the intubation can be quickly and smoothly inserted into the auxiliary pipeline 1.
