Disinfection method:
(1) Heat-resistant and moisture-proof medical instruments, appliances and articles should be sterilized by pressure steam, and heat-resistant oil and dry powder should be sterilized by dry heat;
(2) For heat-resistant and moisture-proof articles, low-temperature sterilization methods such as ethylene oxide sterilization, hydrogen peroxide low-temperature plasma sterilization or low-temperature formaldehyde steam sterilization should be adopted;
(3) When disinfecting the surface of articles, the surface properties should be considered, and a suitable disinfectant or ultraviolet sterilizer should be selected for smooth surfaces. The surface of porous materials should be disinfected by soaking or spraying.
