摘　　要：目的观察汽水分离装置对不同型号过氧化氢低温等离子体灭菌器灭菌能力的促进效果。方法采用不锈钢和聚四氟乙烯管腔,内置染菌载体,采用定性灭菌试验,比较安装汽水分离装置前后,对两种细菌芽孢的灭菌效果。结果未安装汽水分离装置的3台过氧化氢低温等离子体灭菌器,单周期灭菌后,不能全部杀灭模拟管腔内的细菌芽孢;安装汽水分离装置后,灭菌合格率为100%。结论汽水分离装置可以显著提高过氧化氢低温等离子体灭菌器对管腔类器械的灭菌效果。Objective To observe the promoting effect of vapor-water separator in different type of low-temperature plasma sterilizer.Method To put bacteria-carrier in stainless steel or polytetrafluoroethylene tube,after sterilization process with or without vapor-water separator,the biocidal efficacy was compared by quality-decided methods.Results After single cycle,3 low-temperature plasma sterilizer could not kill all the bacterial spores in 30 test tubes when vapor-water separator was not installed,but sterilization was 100% up to standard in 50 test tubes when vapor-water separator installed.Conclusion Vapor-water separator of hydrogen peroxide could promote low-temperature plasma sterilization effectiveness.
