The cleaning equipment connector 9 is connected to the cleaning and disinfection machine. The simulated pollutants include protein and spore pollutants, etc., and the simulated pollutants are accompanied by red pigment prompts. Turn on the cleaning and disinfection machine, and the cleaning and disinfection liquid flows from the equipment liquid inlet 15 to the second intermediate liquid inlet 11, and then enters the endoscope simulation cavity 1 through the endoscope connector liquid inlet 29 to clean and disinfect the inner wall of the endoscope simulation cavity. After the cleaning and disinfection liquid enters the endoscope connector 4 and the first intermediate connector 3 from the other end of the endoscope simulation cavity 1, it enters the first plug cavity 20 of the detection connector 2 to clean and disinfect the inspection piece bonded in the first plug cavity 20, that is, the endoscope simulation cavity 1 and the inspection piece 28 are cleaned and disinfected together.

[0037] The inspection piece 28 bonded to the second insertion cavity 21 is placed together with the endoscope simulation cavity 1 in a container filled with cleaning and disinfecting liquid to clean and disinfect the outer tube wall of the endoscope simulation cavity 1. When the whole process is completed, turn off the switch of the cleaning and disinfecting machine, take out the inspection piece 28 and observe its red pigment. If the red pigment is cleaned and disinfected, it means that the cleaning and disinfection result of the endoscope simulation cavity 1 is qualified, otherwise it is unqualified.

[0038] When the cleaning and disinfection machine has more than two interfaces, the detection device can be cleaned and disinfected together with the endoscope, so as to observe the entire cleaning and disinfection process in real time; when the cleaning and disinfection machine has only one interface, the detection device first performs cleaning and disinfection, observes its cleaning and disinfection results, and then sets the same parameters to clean and disinfect the endoscope. This device simulates the processing environment of endoscope cleaning and disinfection through the endoscope simulation cavity 1 and the inspection piece 28, cleans and disinfects synchronously with the endoscope, and detects the cleaning and disinfection effect of the endoscope. It has the advantages of real-time, rapid, and accurate, making the endoscope cleaning and disinfection process more standardized, reliable, and safe.
