[0025] The silicone main pipe outer tube 2 is provided with a balloon 1 on one side, the balloon 1 can be a silicone balloon or a PU balloon, the balloon 1 is arranged on the silicone main pipe outer tube 2, the silicone main pipe outer tube 2 is the main support of the balloon 1, and the balloon 1 is used for plugging and positioning the human body airway.

[0026] The silicone main pipe outer tube 2 is further provided with a locking pipe 3, the locking pipe 3 is fixed on the silicone main pipe outer tube 2, the locking pipe 3 is internally provided with a capillary tube 12 in communication with the balloon 1, the capillary tube 12 is used for inflating the balloon 1, and the capillary tube 12 is provided with an opening at the position in the balloon 1.

[0027] The locking pipe 3 is preferably a section of silicone pipe, the locking pipe 3 is sleeved on the silicone main pipe outer tube 2, and after the position is fixed, the locking pipe 3 is bonded on the silicone main pipe outer tube 2 by using a silicone adhesive.

[0028] The silicone main pipe outer tube 2 is provided with a fixed inflation device on the side, the fixed inflation device is arranged in cooperation with the locking pipe 3, the fixed cooperation device is installed in communication on the locking pipe 3, the locking pipe 3 can fix the relative position between the fixed inflation device and the silicone main pipe outer tube 2, and the fixed inflation device cannot easily fall off from the silicone main pipe outer tube 2.

[0029] The fixed inflation device is composed of an inflation pipe 7, an indicating air bag 8 and a check valve 11, the inflation pipe 7 is in communication with the capillary tube 12 in the locking pipe 3 after the fixed inflation device is connected on the locking pipe 3, the inflation pipe 7 is used for inflating the capillary tube 12, so as to further inflate the balloon 1.

[0030] The check valve 11 is sequentially connected with the indicating air bag 8 and the inflation pipe 7, after the fixed inflation device is connected with an inflation equipment, the gas enters the check valve 11, the check valve 11 is used for preventing the gas in the fixed inflation device from flowing back, the gas enters the inflation pipe 7 through the indicating air bag 8 to inflate the balloon 1, and the indicating air bag 8 is used for inflating the gas in the balloon 1 to the maximum pressure, the gas supplied by the inflation equipment enters the indicating air bag 8, so that the indicating air bag 8 starts to expand, and the check valve 11 is used for preventing the gas from flowing back.

[0031] When the silicone main pipe outer tube 2 is inserted into the airway and the balloon 1 is moved to the appropriate position, after the positioning of the balloon 1 is completed, the balloon needs to plug the airway, and the fixed inflation device inflates the balloon 1.

[0032] The end of the outer tube 2 of the silica gel main tube, which is not inserted into the airway of the human body, is provided with a connector 5, which is usually a 15mm connector.

[0033] The end of the outer tube 2 of the silica gel main tube, which is not inserted into the airway of the human body, is provided with a connector 5, which is usually a 15mm connector.
