医用空气净化消毒器消毒和净化效果评价

目的评价某品牌多因子组合医用空气净化消毒器对室内空气的净化和消毒效果。方法用多级撞击式空气微生物采样器的采样方法进行了观察。结果由中效过滤、活性炭和静电吸附以及负离子等多种因子组合的医用空气净化消毒器在模拟现场条件下,启动该机器运行30和60min,对空气中人工污染的白色葡萄球菌消除率分别为99.93%和99.95%。在现场房间内,连续开机运行30min,对室内空气中颗粒的清除率达98.5%;开机运行作用60min,对室内空气中自然菌的消亡率平均为95.63%。结论该医用空气净化消毒器对室内空气中颗粒物清除、净化和杀菌性能良好。

EVALUATION OF THE EFFICACY OF PURIFYING DISINFECTOR IN AIR DISINFECTION AND PURIFICATION

Objective To evaluate the efficacy of a multifactorial combination air disinfector in disinfecting and purifying indoor air.Methods Multi-level air microorganism sampler was used to carry out laboratory tests. Results The multifactorial combination air disinfector was composed of multiple factors including medium efficiency filtration, activated carbon adsorption, electrostatic field adsorption and negative ion. Under simulated field conditions, operation of the multifactorial combination air disinfector for 30 and 60 min killed 99.93% and 99.95% of Staphylococcus albus in air. Operation of the air disinfector for 30 min in on-the-spot room removed 98.5% of dust particles in indoor air and operation for 60 min removed 95.63% of the natural bacteria in average in indoor air. Conclusion The air purifying disinfector has good efficacy in removing dust in air, purifying and disinfecting air.
