两种空气消毒机消毒效果比较

为比较洁宇牌和豪邦牌空气消毒机静态与动态消毒效果,对其杀灭手术室内空气自然菌的效果进行了观察。结果,在无人状况下,两种空气消毒机消毒处理30min可使空气中自然菌的细菌总数≤200cfu/m~3;在有人状况下,洁宇牌空气消毒机能使空气中的细菌总数下降51.04％,豪邦牌空气消毒机只能使空气中的细菌总数下降22.92％。可见,两种空气消毒机的静态消毒效果接近,洁宇牌空气消毒机在有人情况下消毒效果比豪邦牌好。

COMPARATIVE DISINFECTION EFFICACY OF TWO KINDS OF AIR DISINFECTOR

In order to compare the static and dynamic disinfection efficacy of Jie-Yu-Brand and Hao-Bang-Brand air disinfectors, their efficacy in killing natural bacteria in air of operating room was observed. The results showed that under unoccupied condition, operation of the 2 kinds of air disinfectors for 30 min could make the total count of natural bacteria in air < 200 cfu/ m3. Under occupied condition, Jie-Yu-Brand air disinfector could reduce the total bacterial count of air by 51.04%, while Hao-Bang-Brand air disinfector could reduce the total bacterial count of air only by 22.92%. It is thus evident that the static disinfection efficacy of the 2 air disinfectors is similar, while the disinfection efficacy of Jie-Yu-Brand air disinfector is better than that of Hao-Bang-Brand air disinfector under occupied condition.
