The intubation tube passes through the annular disc and is rotatably connected thereto. An opening is formed in the end of the fixed ring away from the annular groove. A film is arranged at the opening.

[0007] Preferably, an annular cavity is formed in the fixed ring. The annular cavity is communicated with the annular groove through a through hole. Two symmetrical sliding grooves are formed in the inner wall of the through hole.

[0008] Preferably, two symmetrical sliding blocks are fixedly connected to the sidewall of the intubation tube. The two sliding blocks are slidably connected in the two sliding grooves respectively.

[0009] Preferably, the annular cavity is communicated with the opening.

[0010] Preferably, the annular disc and the inner wall of the annular groove are elastically connected through a plurality of springs. The plurality of springs are arranged at equal intervals in the circumferential direction.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1、 through setting up thin film and opening, initial state, cannula is located in the opening of fixed ring, both sides of slider side wall and annular groove inner wall abut, at this time slider is not in sliding slot, thin film blocks up opening, when inserting cannula, thin film can realize blocking up opening, avoid liquid in human trachea from opening into cannula, cause blockage, greatly improve the anti-blocking effect of cannula.

[0013] 2、 through setting up fixed ring, when inserting cannula, push cannula and air bag into trachea, slider abuts against annular groove inner wall, at this time, slider is not in sliding slot, after inserting cannula in place, rotate cannula to drive both end sliders, make slider correspond to sliding slot position, continue to push cannula, compress spring, one end of cannula pierces thin film and exposes, then rotate cannula again, make both sides of slider rotate to separate from sliding slot corresponding position, loosen cannula, annular disc moves to left side under the action of spring, the side wall of slider abuts against annular cavity inner wall, realize fixing cannula, avoid end part of cannula scratching human trachea when inserting.
