Ethylene oxide sterilization mechanism is through its non-specific alkylation with microorganisms, thereby inhibiting the normal function of the microbial reaction base, so that its metabolism is impaired and death. The sterilization effect of ethylene oxide is related to the temperature, pressure, humidity and concentration of ethylene oxide in the sterilization chamber, and these process parameters at the appropriate values can shorten the sterilization time and achieve the best sterilization effect. Therefore, the work process of the sterilizer first of all the sterilization chamber heating, until the temperature reaches the predetermined sterilization temperature; then, the sterilization chamber vacuum, when the predetermined vacuum degree, began to sterilize the room dosing; at the end of the above process, the timer clock began to work, the sterilization process began; in the entire sterilization process needs to be kept at a constant temperature; when the sterilization time to the sterilization room began to change the air, that is, filtered clean air replacement of the sterilization chamber, the sterilization process is not a good idea. Clean air replacement of residual ethylene oxide gas in the sterilization chamber, the residual gas discharge; residual gas is discharged after treatment by the exhaust gas treatment system. At this point, the entire sterilization process is over.
Overview of ethylene oxide:
Ethylene oxide sterilization device is the key equipment of single-use sterile medical device manufacturers, installation, operation, use and management of its special requirements, the use of ethylene oxide as a sterilizing agent, ethylene oxide is a broad-spectrum sterilizing agent, which can kill a variety of microorganisms, including spores, tuberculosis bacilli, bacteria, viruses, fungi and so on, at room temperature.
