空气排除与蒸汽渗透测试方法

Air removal and steam penetration test

目的介绍对蒸汽灭菌器进行空气排除和蒸汽渗透测试的方法,验证所使用的蒸汽灭菌器具备达到规定无菌水平的能力。方法分析并比较相关国际、国家、医药行业标准,按负载类型测试方法分为BD类测试和空腔负载测试,对测试方法所使用的化学指示物等进行详细阐述。结果 BD类测试和空腔负载测试共同构成了较为全面的空气排除和蒸汽渗透性能测试,对预真空蒸汽灭菌器的性能作出合理评价,保证了灭菌物品的无菌保证水平。结论这些测试方法可用于指导灭菌处理人员的实际工作,控制医院感染。

OBJECTIVE To introduce the test methods for air removal and steam penetration,which can be used to make sure the steam sterilizers in good condition to fill the requirements of SAL. METHODS We made the analysis and comparison of related international standards and found that these were bowie and dick-type test and Hollow load test according to the load processed by the steam sterilizers.national standards and pharmaceutical industry standards,explained the details of chemical indicators that used in test. RESULTS Bowie and Dick-type test and hollow test together formulated an integrated performance test of air removal and steam penetration,which could made a reasonable evaluation of the performance of steam sterilizer so as to ensure the aseptic level of sterilized items. CONCLUSION We suggest that the test methods can be used for the personnel deal with the sterilization work to precaution and control infection.
