Problems solved by technology

High temperature will also lead to incomplete cleaning and coagulation of residual protein, making the adhesion of pollutants stronger and other problems
In addition, due to the rapid development of modern medical devices, some devices made of new materials are not suitable for temperature-sensitive sterilization technology, such as high-precision fiberscopes, artificial organs and internal implants are not resistant to high temperatures

Abstract

The invention discloses a plasma disinfection and sterilization device for medical instruments. The device comprises a high-pressure system, an air compressor and a disinfection chamber. In use of thedevice, metal medical instruments needing to be disinfected are placed in the disinfection chamber, the door of the disinfection chamber is closed, the air compressor is started to compress air to specified density, the compressed air is introduced into a discharge area, and a disinfection switch is turned on for disinfection; after a period of disinfection, a plasma generating device stops working; and a switch of the air compressor is turned off to balance pressure inside and outside the chamber, the door is opened, and the disinfected instruments are taken out for reuse. A plasma technology is adopted in the invention to disinfect the medical instruments, and microorganisms on the medical instruments are killed through active substances in plasma and the action of a strong electric field, so the purposes of sterilization and disinfection are achieved.

Description

technical field [0001] The invention relates to the technical field of plasma disinfection, in particular to a plasma medical device disinfection and sterilization device. Background technique [0002] Medical devices refer to various devices used in the medical field, including various devices for clinical diagnosis and treatment, medical experiments and clinical inspections. The disinfection and sterilization of medical devices is one of the key means to prevent and control nosocomial infections and ensure the quality of medical care. It can be said that without excellent medical device disinfection and sterilization technology, there would be no development of modern surgical technology, and the implementation of various invasion diagnosis and treatment technologies could not be guaranteed. Modern medicine would not be able to achieve such brilliant achievements. [0003] Under the current pressure steam sterilization method, the situation of incomplete sterilization is ...
