紫外线空气消毒器对手术室空气动态消毒效果

EFFICACY OF ULTRAVIOLET AIR DISINFECTOR IN PERIODIC DISINFECTION OF AIR IN OPERATING ROOM

天使牌空气消毒机为由低臭氧高强度紫外线灯和过滤系统组成的循环风紫外线空气消毒器。为了解其对室内空气消毒效果，对空气细菌总数进行了检测。结果，用该机（１３０ｍ３手术室的两端墙上各装１台）消毒３０ ｍｉｎ，空气细菌总数由３１１３ ｃｆｕ／ｍ３减至１６７ｃｆｕ／ｍ。在手术中用该机每隔１５ｍｉｎ消毒作用１５ｍｉｎ，可控制空气细菌总数≤１２５ｃｆｕ／ｍ３。该机对手术室空气动态消毒是有效的。

Tian-Shi-Brand Air Disinfector is a circulating air ultraviolet air disinfector composed of low-ozone high-intensity ultraviolet lamp and filtering system. In order to know its effica- cy in disinfection of the indoor air, the total bacterial count in air was examined. The results showed that disinfection with this disinfector（one disinfector each was installed on the wall of two ends of a 130 m3 operating room) for 30 min reduced the total bacterial count of the air from 313 cfu/m3 to 167 cfu/m3. Periodic disinfection with this disinfector for 15 min each time with 15 min interval could control the total bacterial count in air at ≤ 125 cfu / m3 dur- ing the operation. This disinfector is effective for periodic disinfection of the air in the oper- ating room.
