摘要
目的探讨改善医疗环境的新方法，降低环境因素所引起的医院感染。方法采用纳米光催化技术，对医疗环境进行临床条件下杀菌抑菌效果分析。结果生化衣纳米光触媒喷涂材料对现场3种环境物体表面杀菌作用明显，物体表面总的细菌消亡率为23．75％～38．3C％；垂直表面细菌消亡率为48．77％～87．97％，水平表面细菌消亡率为12．50％～77．20％，空气细菌消亡率为1．52％～60．00％。结论采用纳米光触媒进行医疗环境消毒和净化具有很好的发展前景。
OBJECTIVE To probe into the new method to improve medical environment, and reduce hospital infection causing by the environmental factors. METHODS Using the nanometer photocatalysis technology clinically, to analyze the bacteriostatic effect of medical environment. RESULTS After use of the nanometer photocatalysis spraying material the surface sterilization effect was obvious on the three kinds of environmental objects. The withering away rate of bacterium on the object with total surface was 23.75-38. 30% ; the vertical surface bacterium withers away rate was 48.77-87.97%, the horizontal surface bacterium withers away rate was 12.50-77. 20%, the air bacterium withering away rate was 1. 52-60. 00%. CONCLUSIONS The nanometer photocatalysis technology to sterilize and purify the medical environment has very good perspectives.
