【摘要】：目的比较移动式紫外线杀菌灯和移动式循环风紫外线空气消毒机对矩五拱Ⅵ型折叠式网架帐篷内空气消毒效果,为野战条件下手术帐篷空气净化方法的选择提供依据。方法采用平板暴露法,对2种不同消毒机的消毒效果进行观察。结果 2种消毒机对帐篷内空气消毒后,菌落数较消毒前明显减少(P0.05)。紫外线杀菌灯消毒后、消毒后1 h自然菌消亡率分别为65.30%和43.84%;移动式循环风紫外线空气消毒机消毒后、消毒后1 h自然菌消亡率分别为79.82%和58.77%,但2种消毒方法的消毒效果差异无明显统计学意义(P0.05)。紫外线杀菌灯对帐篷内空气消毒后1~3 h菌落数与消毒前差异无统计学意义(P0.05);移动式循环风紫外线空气消毒机对帐篷内空气消毒后、消毒后1 h菌落数较消毒前减少有统计学意义(P0.05),其余时段菌落数与消毒前差异无统计学意义(P0.05)。结论紫外线杀菌灯和移动式循环风紫外线空气消毒机对帐篷内空气均有明显的消毒效果,消毒效果可维持至消毒后1 h。
[Abstract]:Objective to compare the efficacy of mobile ultraviolet sterilization lamp (UV) and mobile wind ultraviolet air disinfector (UVA) on air disinfection in the tent of rectangular five-arch VI folding grid frame, and to provide a basis for the selection of air purification methods for surgical tents under field conditions. Methods the disinfection effect of two kinds of disinfector was observed by plate exposure method. Results after disinfection of air in tent by two kinds of disinfector, the number of bacteria colony decreased obviously than that before disinfection. After disinfection of ultraviolet lamp, the death rate of natural bacteria was 65.30% and 43.84%, respectively, after disinfection, the rate of death of natural bacteria was 65.30% and 43.84%, respectively. The death rate of natural bacteria was 79.82% and 58.77% at 1 hour after disinfection, but there was no significant difference in disinfection effect between the two methods (P 0.05). There was no significant difference in the number of colonies between 1 and 3 hours after disinfection of air in the tent by ultraviolet lamp, and there was no significant difference in the number of colonies between before and after disinfection, and the air in the tent was disinfected by mobile circulating wind ultraviolet air disinfector. At 1 hour after disinfection, the number of colonies decreased significantly compared with that before disinfection (P 0.05), and there was no significant difference between the number of colonies before disinfection and that before disinfection (P 0.05). Conclusion the ultraviolet disinfection lamp and the mobile circulating wind ultraviolet air disinfector have obvious disinfection effect on the air in the tent, and the disinfection effect can be maintained until 1 hour after disinfection.
