摘　　要：目的研究纳米光催化空气消毒器对眼科门诊手术室消毒效果。方法分别测定该机在有人、无人状态下的消毒效果。结果在无人状态下,纳米光催化空气消毒器与紫外线消毒手术间1 h后,对空气中自然菌的平均清除率分别为88.9%、89.7%;消毒后菌落总数分别为63.9、75.0 CFU/m3;在人员活动状态下,纳米光催化空气消毒器持续消毒,手术进行30、60、120、180 min菌落总数分别为26.6、92.2、150.0、155.3 CFU/m3;而紫外线消毒法菌落总数分别为150.2、166.7、355.17、38.4 CFU/m3。结论纳米光催化空气消毒器在无人及人员活动条件下均可保证空气菌落数在较低水平,明显优于术前紫外线消毒方法。OBJECTIVE To observe the disinfection efficacy of nano-light catalytic air disinfector （Jian Bai Le disinfector） in ophthalmic outpatients operating room. METHODS The efficacy of disinfection of the disinfector in the operating room without and with staff was detected respectively. This efficacy of disinfection was compared with that of uhraviolet ray. RESULTS The average eliminated rate of natural bacteria in the air was 88.9% vs 89.7%, and the average bacterial colony number was 63.9 vs 75.0 CFU/m^3 , respectively, after disinfection by the disinfector or by uhraviolet ray without staff. When the device worked continuously with staff, Their average bacterial colony number was 26. 6, 92.2, 150.0 and 155.3 CFU/m^3 , vs 150. 2, 166.7, 355. 1 and 738. 4CFU/m^3 in the period of 30, 60, 120 and 180 minutes after operation, respectively. CONCLUSIONS The bactericidal efficacy of disinfector is distinctly better than that of uhraviolet ray lamp.
