Furthermore, an inflation valve is arranged on the inflation tube.

Further, the balloon is arranged at the tail end of the tracheal cannula.

Further, the balloons are the same size.

Preferably, the number of balloons is 2.

Further, the balloons are in communication with each other.

Still further, the diameter of the communication between the balloons is smaller than the balloon diameter.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model is provided with a plurality of saccules, all the saccules are connected with the same air inflation channel, and are inflated simultaneously with the same pressure, so that the whole stress area of the tracheal wall is increased under the same pressure, and the pressure damage of the tracheal wall can be reduced;

(2) the multiple balloons form a multilayer sealing structure, and double or multiple sealing effects are achieved under the same conditions;

(3) the mutually communicated saccules have more balanced and consistent internal pressure, and effectively reduce the pressure injury of the tracheal wall.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed" on another element, it can be directly on the other element or intervening elements may also be present.

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows:

as shown in fig. 1, the present embodiment adopts a double balloon design, and a first balloon 4 and a second balloon 5 are arranged at the end of the main body 1 of the endotracheal tube, namely, at the position close to the air outlet, and the first balloon 4 and the second balloon 5 are closely adjacent to each other.

The tracheal cannula body 1 is formed by arranging an air passage 2 and an inflation passage 3 in parallel, wherein the air passage 2 is used as a main air passage for assisting the ventilation of a patient, and the inflation passage 3 is used as an auxiliary air passage for inflating all the balloons.
