Description

technical field [0001] The invention belongs to the technical field of disinfection and sterilization in the medical industry, and in particular relates to an atmospheric pressure low-temperature plasma rapid sterilization control system. Background technique [0002] Endoscope is an important medical device used to observe the lumen of human and animals. It has been clinically used in the diagnosis and treatment of various diseases. Before using the endoscope, it needs to be sterilized to prevent cross-fertilization. Infect. A variety of methods have been used to sterilize endoscopes, such as high temperature and high pressure steam, ethylene oxide fumigation and glutaraldehyde immersion. Among them, the high temperature and high pressure steam sterilization temperature is relatively high, which is easy to cause thermal damage to the surface of the endoscope, and it is difficult to effectively inactivate some pathogenic microorganisms. The sterilization process of the eth...
