环糊精包合碘临床消毒效果的研究

Study on Disinfection Effect of Cydiodine

自行研制的环糊精包合碘具有有效碘含量高、质量稳定和刺激性小等优点。参考《消毒技术规范2002版》的方法,分别以木质桌面、自然水体和鸡舍为消毒对象,验证其临床消毒效果。结果表明,环糊精包合碘1∶800倍(W/V)样品稀释液,对木质桌面消毒作用10 min,对物体表面自然菌的平均杀灭对数值为2.43;1∶10 000倍(W/V)投入自然水体,10 min大肠杆菌杀灭率为100%,10～30 min自然菌杀灭率为99.65%～100%;1∶500倍(W/V)样品稀释液,60 min对鸡舍地面、墙壁自然菌杀灭率为92.73%和93.58%。

A new cydiodine, produced by our team, was studied about its disinfection effect on woody desktop, natural water and hencoop with the （（Technical Standard For disinfection（2002 ed. ）〉〉 for reference. It had the advantages of high iodine content, stable quality and less stimulus. The results showed that with 1 ： （W/V） of cydiodine solution in 10 minutes, the killing log value of natural bacteria on desktop was 2. 43 ; with 1：10 000（W/V） of cydiodine solution, Escherichia coli in water were killed wholly in 10 minutes, while 99.65% - 100% of the natural bacteria were killed in 10 ~ 30 minutes; with 1：500（W/V） of cydiodine solu- tion, 92. 73% and 93.58% of the natural bacteria on ground and wall were killed respectively in 60 minutes.
