Abstract：Objective To study the actual cleaning effect of pulsating vacuum washer-disinfector on ophthalmic instruments, provide
practical data support for hospital disinfection and supply, by comparing with foreign equipment, promote the development of
domestic medical devices. Methods In the experiment, the results of ophthalmic instruments cleaned by our supply center from
January to May 2020 were selected as statistical samples, and the cleaning effect were compared between pulsating vacuum washerdisinfector
and traditional method. At the same time, the damage rate and drying effect of equipment from other manufacturers
in other hospitals in the city were investigated. Results 1021 pieces were cleaned by traditional methods, and 1058 pieces were
cleaned by pulsating vacuum. The cleaning effect were visually combined with biological fluorescence detection method. Among
them, the qualified rate of traditional cleaning method was 92.73%, the qualified rate of vacuum cleaning was 97.14%. ATP test: the
positive rate of traditional cleaning was 15.23%, the positive rate of vacuum cleaning was 5.11%. The damage rate of equipment
is basically the same among the three manufacturers, and there is a big difference in drying: vacuum cleaning was 95.0%, foreign
equipment was 81.0%. Conclusion The pulsating vacuum cleaning and disinfecting device has a good effect on the cleaning of
ophthalmic instruments, which can reduce the manual processing intensity, improve the working efficiency and reduce the damage of
instruments, user satisfaction is better than the same type of control domestic and foreign brands.
