Description

technical field

[0001] The invention relates to a disinfection and sterilization method in the fields of medical treatment and public health, and the technical field of plasma application. Background technique

[0002] The disinfection process refers to the reduction of a large number of pathogenic microorganisms, viruses or proteins present in the interior and exterior surfaces of the objects to be treated to below the specified survival rate or pathogenicity rate. Disinfection methods refer to the methods used in the disinfection process. These methods must effectively kill various microorganisms without endangering the object to be disinfected and the surrounding environment. The existing disinfection methods for medical and surgical instruments more or less have the disadvantages of low disinfection efficiency, endangering the sterilized object, complex operation, high cost and maintenance cost.

[0003] In the field of medical and health care, disinfection is usually a...
