[0002] Medical devices refer to medical instruments, equipment, appliances, and other related items that are used directly or indirectly on the human body. Medical devices include medical equipment and medical consumables. Non-disposable devices that come into contact with the human body during surgery need to be sterilized to achieve a sterile state to facilitate next use and prevent cross-induction of pathogens. Common methods of sterilizing devices include: ethylene oxide sterilization, dry heat sterilization, moist heat steam sterilization, etc.
[0003] Among them, moist heat sterilization is to put the medical equipment in a high-pressure sterilizer, and use high-pressure saturated steam at a minimum temperature of 121 degrees. Heat and moisture are quickly transferred to the sterilized product. The sterilization time is at least 15 minutes, so that the protein and nucleic acid in the microbial cells are denatured, thereby killing the microorganisms. Moist heat sterilization is a commonly used and reliable method in thermal sterilization. When using a sterilizer, medical equipment needs to be placed inside the sterilizer. To take and place, the mobile rack needs to be pulled out of the sterilizer and the items need to be placed on the tray. In this way, the frame needs to be aligned before it can be placed inside the sterilizer, which is cumbersome and troublesome to use. Therefore, we proposed a high-pressure steam sterilization device for medical equipment to improve the above problems. Utility Model Content
