When the air tank 19 is attached to the skin 20 and the negative pressure in the air tank is small, the second regulating switch 17 is adjusted to vent air, the first regulating switch 14 is adjusted to vent air, the second pressure rod 3 is pressed down to enable the liquid in the second pressure barrel 5 to be extruded into the second deformable pressure bag 10, meanwhile, the first movable piston 11 is extruded to ascend, the first movable piston 11 drives the connecting piece 12 to ascend, further, the piston rod 15 is driven to ascend to perform air suction, at the moment, the first regulating switch 14 is in a closed state, meanwhile, due to the pressure, the first deformable pressure bag 9 is reduced, the liquid is extruded into the first pressure barrel 4 through the first cavity tube 6, the first pressure rod 2 ascends, and the air suction action in the air tank 19 is finished; then the first pressure bar 2 is pressed to descend, the first deformable pressure bag 9 is filled with liquid, the first movable piston 11 is pressed to descend, the connecting piece 12 is driven, the piston rod 15 is driven to descend, at the moment, the air outlet mode of the first adjusting switch 14 is in an open state, the second adjusting switch 17 is adjusted to be in a closed mode, and meanwhile, due to the conduction of the liquid pressure, the second pressure bar 3 rises, the air suction action in the primary air cylinder 16 is completed, and therefore, the complete air suction action is completed. This is repeated several times until the patient feels comfortable. When the negative pressure in the gas tank is large, the second adjustment switch 17 is in the intake mode, while the first adjustment switch 14 is adjusted to the intake mode by the piston rod 15, and the operation is performed in the reverse direction as described above.
