紫外线灯使用过程中存在许多问题,直接影响其消毒效果.为了解福山区各医院紫外线灯的使用情况,于1997年6～7月,对全区12所医院110只紫外线灯进行调查,结果如下.1 材料与方法1.1 调查内容 检测紫外线灯照射强度、安装高度、是否有反射罩及除尘情况.1.2 检测方法 在室内温度为21～25℃,相对湿度45%～55%之间进行.先打开紫外线灯,再把紫外线强度计放在灯中心部位下1m处测定.同时测定了除尘前后、加铝制反射罩前后的不同强度.1.3 紫外线强度计 由军事医学科学院微生物学流行病学研究所和航天工业部第七设计院共同研制.1.4 判定标准1.4.1 照射强度 按照射强度大于70μw·s/cm~2为合格标准.1.4.2 安装高度 以距地面2～2.5m或距照射台面1.2～1.5m为符合要求.
There are many problems in the use of UV lamp, directly affect the disinfection effect.In order to understand the use of UV lamps in hospitals in Fu Shan District, from June to July 1997, 110 UV lamps from 12 hospitals in the district were investigated. The results are as follows .1 Materials and Methods 1.1 Survey Content UV lamp irradiation intensity, installation height, whether the reflector and dust removal .1.2 detection method at room temperature 21 ~ 25 ℃, relative humidity 45% ~ 55% UV lamp, and then the UV intensity meter at the center of the lamp 1m measured at the same time measured before and after the dust, plus aluminum reflector before and after the different intensity .1.3 UV intensity meter by the Institute of Microbiology, Academy of Military Medical Sciences and Space Industry of the Seventh Design Institute co-developed.1.4 determine the standard 1.4.1 Irradiation intensity in accordance with the shooting intensity greater than 70μw · s / cm ~ 2 as the eligibility criteria .1.4.2 installation height from the ground 2 ~ 2.5m or from the irradiation table 1.2 ~ 1.5m to meet the requirements.
