What is the principle of sterilization step of ethylene oxide sterilizer?

Disinfection and sterilization principle of ethylene oxide sterilizer;

The sterilization mechanism of ethylene oxide is to inhibit the normal function of microbial reactive groups through its non-specific alkylation with microorganisms, so that their metabolism is blocked and they die. The sterilization effect of ethylene oxide is related to the temperature, pressure, humidity and the concentration of ethylene oxide in the sterilization room. These process parameters can shorten the sterilization time and achieve the best sterilization effect at an appropriate value. Therefore, in the working process of the sterilizer, the sterilization chamber is first heated until the temperature reaches the predetermined sterilization temperature; Then, vacuumizing the sterilization chamber, and adding drugs to the sterilization chamber when the predetermined vacuum degree is reached; After the above process is completed, the clock starts to work and the sterilization process begins; Maintain a constant temperature during the whole sterilization process; When the sterilization time is up, start to ventilate the sterilization room, that is, replace the residual ethylene oxide gas in the sterilization room with filtered clean air and discharge the residual gas; The residual gas is discharged after being treated by the waste gas treatment system. At this point, the whole sterilization process is over.

Overview of ethylene oxide:

Ethylene oxide sterilization device is the key equipment of disposable sterile medical device manufacturers, and its installation, operation and management have its special requirements. Using ethylene oxide as a disinfectant, it is a broad-spectrum disinfectant, which can kill various microorganisms, including spores, tuberculosis, bacteria, viruses and fungi at room temperature.
