目的 了解某型号上层平射紫外线空气消毒器紫外辐照性能以及对医院门诊诊室空气消毒效果.方法 2023年4-6月,以上海市2家医院的门诊诊室作为研究现场,安装某型号上层平射紫外线空气消毒器,检测运行期间不同点位上紫外辐照强度、室内臭氧浓度及空气微生物水平.结果 2.6 m高度处,紫外辐照强度随距离增加而下降;2.1 m安全高度处,紫外辐照强度为(0.2±0.2)μW/cm2.2个诊室的臭氧浓度分别为(0.071±0.010)和(0.081±0.011)mg/m3,且不高于开机前水平(P>0.05).室内空气微生物水平随诊疗活动开展而升高,但试验组与对照组的差异无统计学意义(P>0.05).结论 本研究的上层平射紫外线空气消毒器工作期间对人体安全,但其空气消毒效果有待提高.
Study on the effect of upper flat shot ultraviolet disinfector on air disinfection in consulting rooms of hospital outpatient clinics
Objective To investigate the ultraviolet(UV)irradiation performance of a certain model of upper flat shot UV disinfector for air disinfection and its effect on the air disinfection in consulting rooms of hospital outpatient clinics.Methods From April to June 2023,consulting rooms of outpatient clinics in two hospitals in Shanghai were used as research sites,and a certain model of upper flat shot UV disinfector was installed to detect the UV irradiation intensity,indoor ozone concentration and air microorganism level at different sites during running.Results At a height of 2.6 m,the UV irradiation intensity decreased with the increase of distance;at a safe height of 2.1 m,the UV irradiation intensity was(0.2±0.2)μW/cm2.The ozone concentrations in the two consulting rooms were(0.071±0.010)mg/m3 and(0.081±0.011)mg/m3,respectively,and were not higher than that before running.The microorganism level of indoor air increased with the development of diagnosis and treatment activities,but the difference between the experimental group and the control group was not statistically significant.Conclusion The upper flat shot ultraviolet disinfector in this study is safe for human body during running,but its air disinfection effect needs to be improved.
