The air nozzle 33 is connected to a hard tube 34 at one end away from the cavity 32, and the hard tube 34 is provided with a connection for connecting The connector 35 for external air and the air pump, the isolation layer 31 is made of PVC coated cloth, there are at least four groups of cavities 32, the number of cavities 32 is consistent with the number of air nozzles 33, the height of the air nozzles 33 is greater than or equal to five centimeters, and a switch valve is provided on the air nozzle 33. The air nozzle 33 and the hard tube 34 are both made of hard materials. The end of the hard tube 34 away from the connector 35 is in a closed state. The connector 35 is a three-way valve. The first interface of the connector 35 is connected to one end of the hard tube 34, the second interface of the connector 35 is connected to the external air, and the third interface of the connector 35 is connected to the trachea quick connector.

[0022] First, open the switch valve on the air nozzle 33, connect the air pipe of the air pump to the third interface of the connector 35, open the switch of the connector 35 to connect the third interface with the first interface, supply air to each air nozzle 33 through the air pump, air pipe, connector 35 and hard tube 34, and then supply air to each cavity 32 through the air nozzle 33. When the air pressure in the cavity 32 reaches the target value, directly close the switch of the connector 35 to limit the air intake of the first interface, and then limit the exhaust of the cavity 32 through the air nozzle 33, thereby improving the inflation efficiency. When one or more groups of cavities 32 have insufficient air pressure, close the switch valves of the air nozzles 33 of other groups, open the switch valves of the air nozzles 33 corresponding to the cavities 32 with insufficient air pressure, and then inflate with the air pump.
