An automatic stomach-washing machine with single chip microprocessor

In this paper the main structure, the working principle,the hardware and the software program of an auto-stomach-machine with a single chip microcomputer are introduced briefly,It can display the total flow of clear water pumped into the stomach by digits,indentify and deal with the jam caused by food at the entrance of dirty water automatically,audible and visual alarm for the troubles of pumping system,and complete the whole process of stomach washing automatically under candition in whichthe flow velocity of clear water entering into the stomach and the absolute difference between the entry and the drainage are about 1.5l/min and no more than 100ml respectively.
