3种空气消毒方法对供应室无菌区消毒效果比较

Compare Disinfection Effect With Three Sterilizing Ways in the Aseptic Area of Supply Room

目的探讨紫外线灯、三氧杀菌机、多功能动态杀菌机3种消毒方法对供应室无菌区空气消毒效果。方法采用现场实验法对3种设备在空气消毒中的效果进行比较观察。结果3种消毒方法在无人条件下消毒效果无显著差别(p<0.05),但在有人条件下,仅多功能动态杀菌机能达到标准。结论3种空气消毒法都是控制医院感染的重要手段,但紫外线灯和三氧杀菌机消毒不能在有人条件下消毒。

Objective：In order to know the disinfection effect of three sterilizing ways that used in sterilizing aseptic area of center supply room.Methods：Use field sampling examination method to compare the efficacy in eradicating the natural bacteria in air which is sterilized by ultraviolet rays,muhifunctional dynamic germicide machino,or trioxide disinfector.Results：All the three sterilizing ways have good disinfection effect to sterilize indoor air at the condition of no people in,but with people in muhifuncfional dynamic germicide machine can keep the air to a hygienical standard,（p〉0.05）.Conclusions：The three kinds of air sterilization are important ways to control hospital infetion,but the ultraviolet rays and trioxide disinfector couldn＇t work when people in the room.
