[0004] In the current clinical practice, the entire endoscope pretreatment process is manually completed by medical staff. Not only is the operation process cumbersome and time-consuming, affecting the efficiency of surgical examinations and treatments, but also the different operating habits of each medical staff lead to different disinfection pretreatment effects, making it impossible to achieve a unified quality standard; in addition, the use and cleaning and disinfection of each endoscope must be recorded, including the date of diagnosis and treatment, patient identification and endoscope number, start and end time of cleaning and disinfection, and the name of the operator, etc. In clinical practice, the records related to endoscope leak detection are all recorded manually, and the bedside pretreatment process lacks records and quality control management.

After the recording controller obtains the upper liquid replenishment instruction input by the user through the touch screen, and detects that the upper sterile cup is placed on the corresponding upper cup holder 42 through the photoelectric sensor between the upper liquid outlet 41 and the upper cup holder 42, the liquid pump and the upper liquid dispensing solenoid valve are controlled to open, so that the cleaning agent flows out from the upper liquid outlet to the upper sterile cup; After the recording controller obtains the lower liquid replenishment instruction input by the user through the touch display screen, and detects that the lower sterile cup is placed on the corresponding lower cup holder 46 through the photoelectric sensor between the lower liquid outlet 45 and the lower cup holder 46, the liquid pumping and delivery pump and the lower liquid dispensing solenoid valve are controlled to open, so that the cleaning agent flows out from the lower liquid outlet to the lower sterile cup; It should be noted that the first fluid replenishment of the endoscope automatic pretreatment leak detection device after startup needs to be performed through the upper fluid replenishment instruction.

The host controller 17 controls the air and water supply button pressing column 13 to maintain the first set time t1 at the first distance L1. At the same time, the host controller 17 controls the opening of the air pump 31 and the pressure-maintaining valve 36 of the leak detection unit, and the safety air cavity of the air supply module is connected with the air cavity of the air-using module. After the air supply is realized and lasts for the fourth set time t4, the air pump 31 and the pressure-maintaining valve 36 are controlled to be closed, and the pressure value of the air cavity collected by the pressure sensor is obtained; When the collected pressure value is less than the lower threshold, proceed to step S223; When the deviation between the collected pressure value and the preset pressure value is less than the first set threshold, the process proceeds to step S226; When the collected pressure value is less than the preset pressure value, but the deviation between the two is greater than the first set threshold and less than the second set threshold, proceed to step S225; When the collected pressure value is less than the preset pressure value, and the deviation between the two is greater than the second set threshold, the process proceeds to step S226; S223. The host controller 17 prompts a serious leak or the leak detection interface is not connected through the display 9, and ends; S224. The host controller 17 prompts the display screen 9 with a suspected air leak, and asks for manual wet test confirmation, and the process ends; S225.
