Through the arrangement structure, the operation tasks of water washing, enzyme washing, disinfection, final rinsing and drying can be simultaneously carried out on each flow channel of the enteroscope according to the soft endoscope cleaning and disinfection specification. In the above task, a cleaning liquid source is provided for the cleaning pump 6, the cleaning pump 6 pumps the cleaning liquid into the main pipe 1 through the suction pipe, and then the cleaning liquid is pumped into each flow passage of the gastroenteroscope through the first shunt pipe 2, the third shunt pipe 4 and the fourth shunt pipe 4 by the first shunt tee 7 and the second shunt tee 8 respectively, so that the cleaning purpose in the flow passage of the gastroenteroscope is realized. When the gastrointestinal endoscope without the attached water supply pipeline is cleaned and disinfected, the cleaning task of the gastrointestinal endoscope is completed by closing the valve 9 and passing through the first shunt pipe 2 and the third shunt pipe 4. And in the cleaning process of the gastrointestinal endoscope, because the nozzle is blocked more commonly, the valve 9 is closed at the moment, so that the water flow is concentrated on the cleaning of the nozzle pipeline, and the increased water flow is helpful for breaking through the adhesive force of foreign matters in the gastrointestinal endoscope nozzle, thereby achieving the cleaning purpose.
