step c: starting a hydraulic push rod (222), pushing out the electric suction apparatus (212), adjusting the pressure of the electric suction apparatus (212), connecting a first suction pipe (214) to a negative pressure suction port (213) of a volumetric flask of the electric suction apparatus (212) after the adjustment is finished, clamping the first suction pipe (214) by using a clamp after the connection is finished, blocking the negative pressure suction, and connecting the other end of the first suction pipe (214) to a three-way pipe (215);

step d: connecting a blood conveying pipe (216) to an infusion bag (241), connecting the other end of the blood conveying pipe to a three-way pipe (215), adjusting a regulator of the blood conveying pipe (216), and blocking inflow of gastric lavage fluid;

step e: inserting a stomach tube (217) into the oral cavity of a child patient, fixing the stomach tube by using adhesive tapes, sucking the stomach tube by using a syringe to determine the position of the stomach tube after the fixing is finished, and collecting the sucked liquid into a waste liquid tank (242);

step f: removing the injector from the stomach tube, connecting the stomach tube to a three-way pipe (215), removing a clamp outside a first suction pipe (214), sucking out liquid in the stomach of the infant by using an electric aspirator (212), blocking the first suction pipe (214) by using the clamp, adjusting an adjuster of a blood conveying pipe (216), enabling gastric lavage fluid of an infusion bag (241) to enter the body of the infant through the three-way pipe (215) and the stomach tube (217), irrigating 100mL of the gastric lavage fluid, adjusting the adjuster of the blood conveying pipe (216), blocking the gastric lavage fluid from entering the body of the infant, removing the clamp outside the first suction pipe (214), and sucking out the gastric lavage fluid in the stomach of the infant by using the electric aspirator (212);

step g: and f, repeating the step f until the washed gastric lavage liquid is clear and the gastric lavage is finished, and carrying out subsequent treatment on the infant patient.
