【摘要】：目的探讨医院室内有人条件下持续空气消毒、改善医疗环境空气的新方法,降低环境空气因素所引起的医院感染。方法采用光催化氧化空气消毒器消毒,对医疗环境空气进行临床条件下消毒效果分析。结果模拟试验中,试验用空气消毒器运行30min,对气雾室空气中白色葡萄球菌的杀灭率为99.96%,一次通过平均除菌率为95.72%;现场试验中,消毒器运行60min,对医院Ⅱ类环境和Ⅲ类环境的空气中自然菌清除率为分别为94.24%和93.70%,空气中残存微生物均明显低于GB15982-1995规定;在对正常进行医护活动的产科病房室内,比较未运行和运行空气消毒器,空气中细菌菌落数24h均值差异有统计学意义(t=4.509,P0.01)。结论采用光催化氧化空气消毒器对医疗环境空气进行消毒具有较好的效果,具备推广应用前景。
[Abstract]:Objective to explore a new method of continuous air disinfection and improvement of medical environment air under the condition of hospital indoor people, so as to reduce the nosocomial infection caused by ambient air factor.Methods using photocatalytic oxidation air sterilizer to sterilize the air in medical environment.Results in the simulated test, the air sterilizer was used for 30 minutes, the killing rate of staphylococcus albicans in the air in the aerosol chamber was 99.96, and the average rate of sterilization was 95.72 in one pass.When the sterilizer was operated for 60 minutes, the removal rates of natural bacteria were 94.24% and 93.70%, respectively, and the residual microbes in the air were significantly lower than those stipulated by GB15982-1995, and in the obstetrical wards where the normal medical activities were carried out, the removal rates of natural bacteria were 94.24% and 93.70, respectively.Compared with the unoperated and operated air disinfector, the mean value of bacterial colony number in the air was significantly different in 24 hours.Conclusion the photocatalytic oxidation air sterilizer has a good effect on air disinfection in medical environment and has the prospect of popularization and application.
