Dry-wet plasma sterilization device and method

Abstract

The invention discloses a dry-wet plasma sterilization device and method. The device is characterized by comprising a plasma generation module, a sterilization chamber, an activation water chamber and an air conditioner. The device works in the manner of generating plasmas for sterilization under low temperature and normal pressure, and under a dry-wet condition, activated particles generated by the plasmas are different, and the endurance of bacteria is different, so that sterilization effects better than those achieved by the independent use of a dry method or a wet method are achieved. Wet sterilization refers to atomizing and spraying the activated particles in the plasma activation water chamber into the sterilization chamber and condensing the activated particles on the surface and in a sterilized object to realize set sterilization without any dead angle. Dry sterilization refers to generating high-concentration activated particles directly acting on the object in the sterilization chamber for sterilization by virtue of the plasma generation module and removing surface residues left by sterilization treatment by virtue of dry hot airflow. Dry sterilization and wet sterilization are alternately carried out, and sterilization condition selectivity, low temperature, high efficiency and no residues are achieved.

Description

technical field [0001] The invention relates to the technical field of sterilization of medical instruments, in particular to a device for sterilizing medical instruments by a plasma disinfection and sterilization device combining dry and wet methods. Background technique [0002] At present, minimally invasive surgery is widely used in the medical field because of its small damage to patients. The sterilization efficiency and sterilization pass rate of various endoscopic and endoscopic instruments used in minimally invasive surgery have become the main problems of the hospital. In order to ensure the qualified disinfection and sterilization of medical devices and reduce the infection rate of patients during surgery, it is imminent to provide a reliable, efficient and low-cost sterilization method. The medical devices used in minimally invasive surgery generally do not have the characteristics of high temperature resistance, so low temperature sterilization technology becom...
