Abstract：Objective To design a sterile water preparation device for the final rinsing of sterilized endoscopes. Methods The tap
water was treated by softening filtration system and reverse osmosis system to get ultra-pure water. Then it was treated by ozone
combined with ultraviolet double sterilization system to obtain sterile water. Results The total number of bacteria in the water treated
by ozone combined with ultraviolet double sterilization system was 0. Conclusion The device designed in this paper can not only
produce sterile water, but also sterilize water pipeline. It can ensure that the endoscopes used by patients before endoscopy are sterile,
so as to prevent and control the cross-infection of patients in the process of examination, thus avoiding the occurrence of medical
disputes.
