① The sterilization procedure of ethylene oxide sterilizer should include preheating, pre-wetting, evacuation, gasification of ethylene oxide to reach a predetermined concentration, maintenance of sterilization time, removal of ethylene oxide gas in the sterilization cabinet, Analyze to remove ethylene oxide residues in sterilized items.
②100% pure ethylene oxide or mixed gas of ethylene oxide and carbon dioxide can be used for ethylene oxide sterilization. The use of freon is prohibited.
③The analysis can be continued in the ethylene oxide sterilization cabinet, or it can be placed in a special fume hood. Natural ventilation method should not be used. The repeatedly input air should be filtered through high efficiency, which can filter out more than 99.6% of particles ≥0.3um.
④Ethylene oxide residue mainly refers to ethylene oxide and its two by-products chloroethanol ethane and ethylene glycol ethane that are left in articles and packaging materials after ethylene oxide sterilization; exposure to excessive ethylene oxide Alkane residues can cause burns and irritation in patients. The amount of ethylene oxide residue is related to the sterilized material, sterilization parameters, packaging materials and packaging size, loading capacity, analytical parameters, etc. At 60 ° C, the polyvinyl chloride tube is analyzed for 8 hours; at 50 ° C, it is analyzed for 12 hours. Some materials can shorten the analysis time, such as metal and glass can be used immediately, and some materials need to extend the analysis time, such as a built-in pacemaker.
