s3, when water or liquid is required to be injected, the injection assembly injects gas or liquid to be injected into the cavity through the second pipeline, and then the gas or liquid flows into the stomach through the through hole and can be used for injecting gas or liquid medicine;
s4, gas is sprayed out of the gas pump, the flow direction of the gas is adjusted through the four-way valve, and when the gas flows to the water tank, the water in the water tank can be pressed into the second pipeline; when gas flows to the medicine box, the medicine in the medicine box can be pressed into the second pipeline, so that the medicine liquid is pressed into the cavity, and the medicine liquid flows out of the through hole and can inflate the air bag when the gas flows to the air bag.
