摘要
目的 观察某等离子体消毒模块对物体表面的消毒效果,为实际消毒应用提供科学依据.方法 采用模拟现场消毒试验方法,用某等离子体消毒模块对物体表面消毒效果进行实验观察.结果 用该等离子体发生器模块,距离物体表面垂直高度1.5 cm照射作用10 min,对物体表面污染的白念珠菌和枯草杆菌黑色变种芽孢的平均杀灭对数值分别为2.28和1.90;照射消毒2 min,对物体表面上大肠埃希菌、金黄色葡萄球菌和铜绿假单胞菌平均杀灭对数值均＞3.00.结论 该等离子体发生器模块近距离照射物体表面,对细菌繁殖体具有较好的杀灭效果,对真菌和细菌芽孢的杀灭效果较差.
Abstract
Objective To observe the disinfection efficacy of a plasma disinfection module on object surfaces,and to provide scientific basis for practical disinfection application.Methods The disinfection efficacy of a certain plasma disinfection module on object surfaces was experimentally observed with simulated field disinfection test method.Results When the plasma generator module was irradiated for 10 min from the vertical height of 1.5 cm above the surface,the mean killing logarithm values of Candida albicans and Bacillus subtilis var.niger spores on the surface were 2.28 and 1.90,respectively.After irradiation and disinfection for 2 min,the logarithm killing values of Escherichia coli,Staphylococcus aureus and Pseudomonas aeruginosa on the surfaces of objects were all＞3.00.Conclusion The plasma generator module has a good killing effect on vegetative forms of bacteria,and poor killing effect on fungi and bacterial spores when irradiated at colse range.
