目的：研究医疗器械灭菌包的灭菌参数与验证。方法：将体积为30cm×40cm×60cm、质量为20kg的120个灭菌包用Belimed灭菌器进行灭菌参数验证。结果：120个灭菌包中的600支快速阅读生物指示剂，有155支阳性，445支阴性；细菌检测有53包阳性；1243指示卡失败9例；湿包52个。结论：灭菌参数为负压脉，中3次，正压脉冲5次，灭菌温度134℃，灭菌时间11min，干燥时间11min，达到《消毒技术规范》的灭菌要求。

Verification and Research of Parameter on Sterilization Wrap of Medical Instrument

Objective To reach parameter on sterilization wrap of medical instrument. Methods The parameter of one hundred twenty sterilization wraps with size 30 cm×40 cm×60 cm and weight 20kg was tested by Belimed sterilizer. Results There are 155 masculine gender and 445 negative in 600 quick reading biological indicators of 120 sterilization wraps and 53 masculine in bacteria detection, 9 cases failure in 1243 indicator, 52 wet wraps. Conclusion The parameter was to take three times negative pressure pulse and five times pressure pulse, sterilization temperature 134℃, sterilization time l lmin and dry time l lmin, matching to sterilization request of ＂Technical Standard For disinfection＂.
