摘要
目的了解一种快速手消毒液消毒性能,观察其杀菌效果。方法用载体定量杀菌试验和现场消毒试验进行了试验。结果用含苯扎氯铵879 mg/L的快速手消毒液原液作用0.5 min,对载体上大肠杆菌、金黄色葡萄球菌、白色念珠菌的杀灭率均达到100%。体积分数50%小牛血清对该消毒液杀菌效果有轻微影响。用该消毒液原液对志愿者手擦拭消毒作用1 min,对手上自然菌的杀灭率达到90%以上,且手上残留菌落数符合国家卫生标准。结论快速手消毒液对细菌繁殖体和真菌具有良好的杀灭效果,对志愿者手具有较好的消毒效果。
Objective To know the disinfection property of a quick hand disinfection solution and to observe its germicidal efficacy. Methods Carrier quantitative germicidal test and on - the - spot disinfection trial were used to carry out experiment. Results The killing rates of Escherichia coli, Staphylococcus aureus and Candida albicans on carriers exposed to the stock solution of the quick hand disinfection solution containing benzalkonium chloride 879 mg/L for 0.5 min attained 100%. 50% (v/v) calf serum influenced slightly the germicidal efffcacy of the disinfection solution. Wiping the hands of volunteers with the stock solution of the disinfection solution for 1 min killed over 90% of the natural bacteria on hands and the residual bacterial colony count on hands met the national sanitary standard.. Conclusion The quick hand disinfection solution has good efficacy in killing regetative forms of bacteria and fungi and good efficacy in disinfection of hands of volunteers.
