摘要 目的研究脉冲氙光灯对传递窗及舱内物体表面消毒的效果。方法采用载体定量杀菌试验方法,对一种脉冲氙光消毒传递窗舱内物体表面的消毒效果进行观察。结果脉冲氙光消毒传递窗消毒作用1 min、3 min、5min和10 min,对受试金属片及纸片两种载体表面金黄色葡萄球菌、铜绿假单胞菌及大肠杆菌的杀灭对数值均> 3,符合2002年版《消毒技术规范》要求;而脉冲氙光消毒传递窗消毒作用1 min、3 min、5 min和10 min,对受试金属片和纸片载体表面枯草芽孢杆菌黑色变种和白色念珠菌的杀灭对数值均<3,但杀灭率均在90%以上。结论脉冲氙光消毒传递窗对舱内物体表面细菌繁殖体具有杀灭效果,对舱内物体表面枯草芽孢杆菌黑色变种和白色念珠菌的也具有一定的杀菌作用;且该消毒方式作用时间较短,可以实现对舱内多种物体表面的快速消毒。 Objective To investigate the disinfection effect of pulsed xenon light on transfer window and the surface of objects inside the cabin.Methods The disinfection effect of a pulsed xenon light on the surface of objects in transfer window was observed by the carrier quantitative sterilization experiment method.Results The killing logarithm values of Staphylococcus aureus,Pseudomonas aeruginosa and Escherichia coli on the surface of the tested metal sheets and paper sheets were all>3 after disinfection of pulsed xenon light in transfer window for 1 min,3 min,5 min,10 min,in line with the requirements of Technical Standard For Disinfection(2002 edition);the killing logarithm values of Bacillus subtilis var.niger and Candida albicans under the same conditions were all<3,but the killing rate was above 90%.Conclusion The pulsed xenon light disinfection for transfer window has a great effective killing effect on the bacterial propagule on the surface of the object in the cabin.It also has a indistinctive bactericidal effect on Bacillus subtilis var.niger and Candida albicans on the surface of the cabin object.Moreover,the disinfection method has a short acting time,and will achieve rapid disinfection of the surface of many objects in the cabin.
