目的分析多功能空气消毒机在普通内科病房的动态消毒效果,为病房空气质量的控制提供参考依据。方法 2010年9月-2011年4月对普通内科病房在动态状态下进行细菌检测并使用多功能空气消毒机消毒,并就消毒前后的空气细菌菌落总数进行分析比较。结果在动态状态下,病房关门关窗并开启空调机时,使用多功能空气消毒机消毒前的空气细菌菌落总数显著高于消毒后,差异有统计学意义(P<0.05);病房在开门开窗时,使用多功能空气消毒机消毒前后的空气细菌菌落总数比较,差异无统计学意义(P>0.05)。结论普通内科病房在关门关窗并开启空调机动态状态下,使用多功能空气消毒机可以降低空气细菌菌落总数,改善房间空气质量。
Objective To analyze the dynamic disinfection effect of multifunction air disinfection machine in general medical ward and provide reference for air quality control in ward. Methods From September 2010 to April 2011, the bacteria were detected in the general medical ward under dynamic conditions and disinfected with a multi-functional air disinfection machine. The total number of airborne bacterial colonies before and after disinfection was compared and analyzed. Results In the dynamic state, when the ward closed the window and turned on the air conditioner, the number of airborne bacterial colonies before using the multifunctional air disinfection machine was significantly higher than that after disinfection (P <0.05) Window, the use of multi-functional air disinfection machine before and after disinfection of bacteria in the total number of air compared, the difference was not statistically significant (P> 0.05). Conclusion The common medical ward closed the window at the close and open the air conditioner dynamic state, the use of multi-functional air disinfection machine can reduce the total number of airborne bacterial colonies, improve the room air quality.
