In the second embodiment shown in fig. 2, an inner inflation tube 3 is arranged in the pressure stabilizing bag 4 along the length direction, the upstream end of the inner inflation tube 3 extends out of the upstream end of the pressure stabilizing bag 4 and is connected with the downstream end of the first inflation tube 1, and the upstream end of the inner inflation tube 3 and the upstream end of the pressure stabilizing bag 4 are connected in a sealing manner by gluing.

The pressurized gas in the inner inflation tube 3 enters the pressure stabilizing bag 4 through the inner pressure stabilizing hole 6 to realize primary pressure stabilization, and then enters the protective shell 5 through the outer pressure stabilizing hole 7 to realize secondary pressure stabilization.

The utility model discloses a theory of operation is: as shown in fig. 5, when in use, the air inlet connector 2 of the first inflation tube 1 is connected to the air bag pressure supplementing device A, and the air inlet connector 9 of the second inflation tube 8 is connected with the mouthpiece end of the laryngeal mask endotracheal tube B or the endotracheal tube C or the double-cavity endotracheal tube D according to different use objects. The air bag pressure supplementing device A simultaneously fills air into the pressure stabilizing bag 4 and the air passage products through the inner inflating tube 3, the first inflating tube 1, the second inflating tube 8 and the inner pressure stabilizing hole 6 on the inner inflating tube 3. In the inflation process, the pressure stabilizing bag 4 assists in gas shunting, and prevents the gas from being filled into the intubation air bag too fast. When the intubation air sac has air leakage, the air in the pressure stabilizing bag 4 can also be supplemented into the intubation air sac. Meanwhile, the pressure of the stabilizing bag 4 is the same as that of the intubation air bag, so that whether the pressure supplementing equipment works effectively, whether the intubation air bag is full, and whether air leakage exists in the whole inflation passage can be indicated.
