PROBLEM TO BE SOLVED: To provide an automatic intestinal dosing device having a drainage function. An intestinal automatic dosing device with a discharge function includes an air pump 1, a first solenoid valve 2, a second solenoid valve 3, a buffer container 4, a first pressure sensor 5, a third solenoid valve 6, and a liquid storage. It is equipped with means 7, a fourth solenoid valve 12, a waste liquid means 14, and a controller, and the gas path and the liquid path are separated. The operating pressure is monitored by a pressure sensor and the output amount of the air pump is dynamically measured in real time. By adjusting, the pressure in the liquid storage bottle and the flow rate of the liquid are stabilized, and while the chemical solution reaches the lesion site at a constant pressure, the one-way valve 10 and the pinch valve 8 prevent the liquid from flowing back and contaminating the pipe. ..
