[0002] Cleaning and disinfection of medical devices is a crucial part of medical treatment, which is related to the health and safety of patients. High-temperature sterilization is one of the main methods of medical device disinfection. It mainly uses high temperature to destroy microbial proteins and enzymes to make them inactive, thereby achieving the purpose of killing microorganisms. At present, high-pressure steam sterilizers are often used in hospitals to sterilize medical devices. After the medical devices are loaded into the sterilizer, they are sterilized by contacting the high-temperature steam with the devices. When there are many medical devices, they are stacked and overlapped together, and the disinfection effect of the overlapping parts is poor. The number of devices that can be disinfected in a limited space is small, and because the medical devices are stationary, it is difficult for high-pressure steam to fully contact all parts of the medical devices.
