Clinical applicability of hospital air disinfection equipment;

Observation on efficacy of different air disinfection methods in blood-collecting environment;

[Objective]To study the effect of air sterilization using chlorine dioxide in common room and in whole closed room.

MethodsThe air sterilization effects were observed and compared for the 3 time spans from 2∶00 to 4∶00 in the early morning, 11∶30 to 12∶30 at noon and 11∶30 to 13∶30.

[Objective]To evaluate the effect of air sterilization in tunnel with Chlorine diocide(ClO_2)for providing the medical support for persorinel assigned.

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.

In order to observe the efficacy of a newly developed high voltage air disinfector in purifying indoor air, P-5-type digital dust meter and sampling of air with a full-glass liquid impingement sampler were used for examining the efficacy of this disinfector in reducing dust and eliminating microorganisms.
