[0024] The connecting combination sleeve 1 and the connecting straight tube 2 are integrated into a structure, and the internal space of the connecting straight tube 2 is interconnected with the gas flow hole 5. The connecting straight tube 2 installed on the connecting combination sleeve 1 can facilitate the subsequent balloon to be quickly installed on the connecting straight tube 2 for testing.

[0025] The diameter of the docking hole groove 3 is larger than the diameter of the sealing docking hole 4, and the diameter of the sealing docking hole 4 is larger than the diameter of the gas circulation hole 5, and the diameter of the sealing docking hole 4 is smaller than the inner diameter of the sealing rubber ring 6. The diameters of the docking hole groove 3 and the sealing docking hole 4 facilitate precise alignment and sealing during the assembly process.

[0026] The connection method between the oxygen cylinder docking sleeve 7 and the sealing protective rubber sleeve 8 is hot-melt fixing, and the inner side of the top end of the sealing protective rubber sleeve 8 is set as an inclined structure. The sealing protective rubber sleeve 8 is fixed inside the oxygen cylinder docking sleeve 7.

According to the structure of the balloon, the balloon interface is closely attached to the outer surface of the connecting straight pipe 2 to avoid deflation. If leakage occurs at the oxygen cylinder interface, the gas will enter the gas flow hole 5 and the connecting straight pipe 2 through the gas discharge through hole 12 and then be discharged into the balloon, so that the balloon changes and expands. The balloon does not change, and the oxygen cylinder is sealed. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
