Disinfection method of medical instruments

Disinfection of medical devices can be put into the medical device disinfection cabinet for disinfection.

Medical instrument disinfection cabinet is a tool to sterilize, insulate and dehumidify medical instruments, surgical special equipment, towels, clothes, tableware, medical facilities and other items by ultraviolet rays, far infrared rays, high temperature (high temperature disinfection through heating pipes) and ozone.

Some items, such as surgical instruments after high temperature and high pressure, can be stored aseptically, sterilized during storage, and stored for a long time, which is convenient for the field use of sterilized items.

Ultraviolet rays and ozone are used to disinfect articles at normal temperature and humidity. Time and simple operation are the quickest ways to sterilize special instruments (not high temperature and high pressure).

Extended data

The pathogens of different infectious diseases have their own characteristics and have different tolerance to different disinfection methods. If bacterial spores have the strongest tolerance to various disinfection measures, they must be treated with strong fungicides, heat or radiation to achieve better results. Therefore, it is generally considered to be the representative of the most difficult disinfection.

The same disinfection method often has different effects on articles with different properties. For the wall with smooth paint, it is not easy to stay when spraying water, so it should be cleaned and wiped. For rough walls, it is easy to make the medicine stay, and it can be sprayed for disinfection. Ethylene oxide fumigation has a good effect on cloth and paper which are easy to adsorb drugs, but it needs to extend the time for metal surfaces.

Disinfection of feces and sputum should not be treated by solidified protein medicine disinfection cabinet, because protein coagulation can protect pathogens. Although high-pressure steam sterilization is effective, it is not suitable for fur, plastic and man-made fiber products.

Ethylene oxide fumigation of celluloid products, bleaching powder soaking cotton fabrics with high concentration of peracetic acid or chlorine-containing disinfectant, and soaking latex gloves for many times for a long time can all cause damage. Food and tableware should not be treated with toxic or odorous disinfectants.
