[0022] In this way, the support cylinder 6, the sleeve ring 12, the first connecting rod 15, the connecting sleeve 16, the second connecting rod 17 and the film 19 form an umbrella structure. When the sleeve ring 12 is moved by the driving assembly, the film 19 can be unfolded or folded for contraction by the first connecting rod 15 and the second connecting rod 17. When the film 19 is contracted and enters the accommodating cavity 4 by the driving of the electric telescopic rod 5, the tracheal tube 1 can be conveniently inserted into the patient's body. When the electric telescopic rod 5 pushes it out again and unfolds under the driving of the driving assembly, the film 19 is opened and tightly attached to the tracheal wall or esophageal wall, which can prevent the free flow of gas or liquid, thereby forming a relatively sealed space. This space is used for inflation or water injection to observe whether there is air leakage or water leakage. During the unfolding process, the area of the film 19 can be gradually adjusted according to the distance that the sleeve ring 12 is moved by the driving assembly, so as to adapt to the diameters of the trachea and esophagus of different patients.
