METHOD FOR DYNAMIC GAS STERILIZATION OF MEDICAL MATERIALS IN SUPERCRITICAL CARBON DIOXIDE ENVIRONMENT (EMBODIMENTS) Russian patent published in 2023 - IPC A61L2/00 

FIELD: sterilization.

SUBSTANCE: method for sterilizing medical instruments and products includes airtight packaging of instruments and products in brown paper bags used in medicine, characterized in that liquid carbon dioxide CO₂ or its mixture with argon at elevated pressure is used as a sterilizing medium, and sterilization is carried out in a dynamic mode in for 15-120 minutes in the temperature range of 37-90°C at a pressure of 30-300 atm by repeating the cycles of pressure gain and decompression with pressure relief to atmospheric pressure by free flow. A variant of this sterilization method is also disclosed in combination with simultaneous ultrasonic exposure at 35 kHz, 100 W.

EFFECT: group of inventions provides effective sterilization of materials of various classes.
