METHOD FOR LOW-TEMPERATURE PLASMA VACUUM STERILIZATION OF PRODUCTS Russian patent published in 2022 - IPC A61L2/26 A61L2/14 

Abstract RU 2772541 C2

FIELD: medicine.

SUBSTANCE: invention relates to the field of medicine and is intended for plasma vacuum sterilization of medical devices. The method for low-temperature plasma vacuum sterilization of products includes placing the product to be sterilized in the sterilizer chamber, evacuating the sterilizer chamber, generating plasma, interacting with a sterilizing agent, which is an aqueous composition containing hydrogen peroxide and an organic acid, which is lactic, citric or acetic acid. When the concentration of hydrogen peroxide in the sterilizing agent is from 20 to 45%, the concentration of organic acid is from 12.5 to 20%, and when the concentration of hydrogen peroxide in the sterilizing agent is from 45 to 50%, the concentration of organic acid is from 1 to 20%.

EFFECT: invention provides safe sterilization of medical devices by reducing the concentration of hydrogen peroxide solution, and thereby reducing the chemical load on the glass and/or plastic components of medical equipment and instruments, as well as increasing the bactericidal properties of the sterilizing agent.
