Embodiment Construction

[0012] The method step of sterilization of the present invention is as follows:

[0013] 1) Place the medical device to be sterilized in a closed container;

[0014] 2) Vacuumize the closed container so that the vacuum pressure in the container is controlled within the range of 1-1500Pa, preferably 1-2Pa;

[0015] 3) Air and / or oxygen and / or inert gas are introduced into the closed container, and the vacuum pressure in the container is maintained at 1-1500Pa;

[0016] 4) After feeding the above-mentioned gas, feed microwave into the container again, the power of the microwave is advisable to ionize the gas passing into the closed container;

[0017] 5) After the sterilization and disinfection, cut off the microwave, and open the atmosphere to release the vacuum to complete the whole working process.

Abstract

A medical instrument sterilization method is disclosed, which characterizes in following process: pending medical instrument for sterilization treatment being placed in a closed container, then being vacuum pumped, the vacuum pressure of the container being controlled between 1 Pa to 1500 Pa, air and/or oxygen and/or inert gases are charged to closed container and the vacuum pressure being between 1 Pa to 1500 Pa, microwave is fed, the favorable power of which should make the gas charged into the container to generate ionization, the microwave be cut after the sterilization, then air being charged to release vacuum to finish the whole process.

Description

Technical field: [0001] The invention belongs to the field of sterilization of medical instruments and relates to a method for sterilizing medical instruments by using microwaves to excite plasma. 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. Invention content: [0003] The purpose of the present invention is to provide a method for sterilizing medical instruments using microwave-excited plasma, which can sterilize all kinds of complicated medical instruments, and the sterilization is thorough, and the sterilization of the present invention is carried out at normal temperature. Therefore, it will not have any impact on...
