Embodiment Construction

[0015] The present invention utilizes microwave to excite plasma to carry out the method steps of sterilization of medical equipment as follows:

[0016] 1. Place the medical device to be sterilized in a closed container;

[0017] 2. Vacuumize the closed container so that the vacuum pressure in the container is controlled within the range of 1-1500Pa, preferably 1-2Pa;

[0018] 3. Introduce air and / or oxygen and / or inert gas into the closed container, and maintain the vacuum pressure in the container at 1-1500Pa;

[0019] 4. After the above-mentioned gas is introduced, microwaves are fed into the container. The power of the microwaves is appropriate to ionize the gas passed into the closed container, and the medical devices in the closed container can be sterilized. The disinfection time is based on Different types of instruments or bacteria have different lengths;

[0020] 5. After the sterilization and disinfection, cut off the microwave, and open the atmosphere to release...

Abstract

A method for sterilizing the medical equipment or tools by microwave excited plasma includes putting said medical equipment or tools in an enclosed container, vacuumizing it until its vacuum pressureis 1-1500 Pa, passing air and / or oxygen gas and / or inertial gas, and feeding microwave in the container for ionizing said gas to sterilize. Its sterilizer is composed of sealed container, microwave source, gas source and vacuumizing pump.

Description

technical field [0001] The invention relates to a method and a device for sterilizing medical instruments by using microwaves to excite plasma, belonging to the field of medical instrument sterilization. Background technique [0002] At present, many medical devices, especially some complex medical devices such as endoscopes, are difficult to be sterilized by conventional methods. There are always residues on the devices, and the gaps in the devices cannot be sterilized. In addition, the plastic parts in the instruments are affected during high-temperature sterilization, shortening their service life. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems, and propose a method and device for sterilizing medical instruments using microwave-excited plasma, which can sterilize and sterilize all kinds of complicated medical instruments, and the sterilization is thorough, and the present invention The sterilization is ca...
