【摘要】：目的观察一种血透机专用次氯酸钠消毒液消毒相关性能。方法采用悬液定量杀菌试验和对血透机管道的模拟现场消毒试验,对该血透机专用次氯酸钠消毒液的杀菌效果和对血透机管道的模拟现场消毒效果进行试验观察。结果该血透机专用次氯酸钠消毒液原液含有效氯47.80 g/L。以其1∶22.5倍稀释液作用5 min,对悬液内大肠杆菌、金黄色葡萄球菌、铜绿假单胞菌的平均杀灭对数值5.00,对悬液内白色念珠菌的平均杀灭对数值4.00。以其1∶40倍稀释液对血透机管道进行模拟现场消毒试验,对30个染有枯草杆菌黑色变种芽孢的聚四氟乙烯管载体消毒作用20 min,杀灭对数值均3.00。结论该血透机专用次氯酸钠消毒液能有效的快速杀灭细菌繁殖体和致病性真菌以及细菌芽孢。对血透机管道消毒效果符合国家要求。
[Abstract]:Objective to observe the disinfectant performance of a special sodium hypochlorite disinfectant for hemodialysis machine. Methods suspension quantitative germicidal test and simulated field disinfection test were used. The germicidal efficacy of sodium hypochlorite disinfectant for this hemodialysis machine and the simulated field disinfection effect on the conduit of hemodialysis machine were observed. Results the available chlorine was 47.80 g / L in the original solution of sodium hypochlorite disinfectant for the purpose of the hemodialysis machine, and 1: 22.5 times thinner than that of the sodium hypochlorite disinfectant solution. E. coli in suspension was treated with release solution for 5 min. The average logarithm of killing Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans in suspensions were 5.00 and 4.00 respectively. 30 polytetrafluoroethylene tube carriers infected with spores of Bacillus subtilis var. Niger were disinfected for 20 min and the logarithmic values were all 3.00.Conclusion Sodium hypochlorite disinfectant for the purpose of this hemodialysis machine is effective in killing bacterial reproduction and pathogenicity. Bacteria and bacterial spores. The disinfection effect of the blood dialyzer pipe meets the national requirements.
