Problems solved by technology

[0002] In the plasma plasma sterilization technology, low-pressure glow discharge plasma sterilization is commonly used, but the existing low-pressure plasma sterilization equipment has great limitations: first, it needs a negative pressure environment, and it needs to be evacuated to below 100Pa by a vacuum pump , when the medical device contains water or liquid or dirt, it may not be able to obtain the required low pressure; second, the low pressure plasma must be in the vacuum chamber to obtain a vacuum, and the size of the vacuum chamber and the distance between the electrodes determine the quality of the object to be processed. size, objects to be processed that are too large or unsuitable cannot be placed in the vacuum chamber; third, the sterilization efficiency is very low because of the need for vacuuming

Abstract

The invention provides an atmospheric plasma sterilizer used in a medical device sterilization apparatus. The atmospheric plasma sterilizer comprises a plasma generating power source, a plasma jet head and a mounting member. The mounting member has a C-shaped structure. The plasma jet head is connected to one end of the mounting member. The plasma jet head is connected to one pole of the plasma generating power source through a high voltage insulated cable and the other pole of the plasma generating power source is connected to a mounting table. The plasma jet head comprises a cylindrical casing formed from a nozzle, a head housing and a rear cylinder connected in an order, an inner plasma generating device and an insulating layer between the cylindrical casing and the plasma generating device. The rear cylinder is connected to the mounting member of the plasma sterilizer. The atmospheric plasma sterilizer used in a medical device sterilization apparatus can carry out sterilization and disinfection under atmospheric conditions, does not need a low air pressure environment, and can realize sterilization and disinfection through placement of the surface of a medical apparatus to be treated under injection of a plasma flow.
