目的：观察三氧消毒杀菌机空气消毒效果。方法：在一定温度、相对湿度分别是４５％～６０％和６４％～７０％下用三氧消毒杀菌机消毒病房和手术室３小时，消毒后半小时行自然沉降法空气采样，样本置３７℃温箱培养２４小时并计算菌落数得出消毒合格率。结果：两种湿度范围下空气消毒合格率病房分别是６４．３％和９２．９％，手术室分别是５％和１００％，存在显著差异（χ２检验，Ｐ分别小于０．０２５与０．００１）。结论：相对湿度对三氧消毒杀菌机空气消毒效果影响较大，在湿度较高时可以使空气消毒达到预期效果
Objective: To observe the disinfection of aerobic air disinfection effect. Methods: The ward and operating room were disinfected for three hours at a certain temperature and relative humidity of 45% -60% and 64% -70%, respectively. The samples were air-conditioned by natural sedimentation method half an hour after disinfection. C incubator 24 hours and calculate the number of colonies obtained disinfection pass rate. Results: The qualified rates of air disinfection in two kinds of humidity ranges were 64.3% and 92.9% respectively, and the operating rooms were 5% and 100% respectively. There was significant difference (χ2 test, P less than 0.025 and 0 respectively). 001). Conclusion: The relative humidity has a great influence on the sterilizing effect of air in the triplex sterilizer. When the humidity is high, air disinfection can achieve the expected effect
