【摘要】：目的观察邻苯二甲醛(OPA)对消化内镜模拟现场杀灭细菌和病毒的消毒效果。方法采用悬液定量杀菌试验方法和模拟现场消毒试验方法,对邻苯二甲醛杀灭细菌和病毒的效果,同时对消化内镜模拟现场消毒效果进行观察。结果该邻苯二甲醛消毒液原液含邻苯二甲醛5 600 mg/L。以邻苯二甲醛浓度为2 800 mg/L消毒液对悬液内大肠杆菌、金黄色葡萄球菌、铜绿假单胞菌作用2.5 min,杀灭对数值均5.0。邻苯二甲醛浓度为2 800mg/L消毒液对悬液内白色念珠菌和龟分枝杆菌脓肿亚种作用2.5 min,杀灭对数值均4.00;对悬液内脊髓灰质炎病毒的灭活对数值4.00。以邻苯二甲醛浓度为5 600 mg/L的消毒液,在消化内镜上运行一个消毒周期(总运行时间为15min,含消毒程序5 min),对消化内镜模拟管腔内铜绿假单胞菌杀灭对数值均5.00。结论该邻苯二甲醛消毒液可快速杀灭悬液内细菌、分枝杆菌和病毒,消化内镜模拟现场消毒试验消毒效果良好。
[Abstract]:Objective to observe the disinfection effect of phthalaldehyde (OPA) on bacteria and viruses in digestive endoscopy. Methods suspension quantitative germicidal test and simulated field disinfection test were used to kill bacteria and viruses. At the same time, the disinfection effect of digestive endoscopy was observed. Results the original solution of phthalaldehyde disinfectant contained 5 600 mg / L phthalaldehyde. Escherichia coli and Staphylococcus aureus in suspension were treated with 2 800 mg/L disinfection solution of phthalaldehyde. Pseudomonas aeruginosa was exposed to 2.5 min, killing logarithmic value was 5.0.The concentration of phthalaldehyde was 2 800 mg / L disinfection solution for 2.5 mins on Candida albicans and Mycobacterium tortoise abscess subspecies in suspension, the logarithmic value was 4.00 for poliomyelitis in suspension. Toxic inactivation logarithm 4.00. disinfectant solution with phthalaldehyde concentration of 5 600 mg/L, A disinfection cycle was performed on the digestive endoscope (total operation time was 15 min, including disinfection procedure 5 min). The logarithmic values of Pseudomonas aeruginosa in the simulated tube of digestive endoscope were 5.000.Conclusion this phthalaldehyde disinfection solution can quickly kill bacteria in suspension. Mycobacterium and virus, digestive endoscopy simulation site disinfection test disinfection effect is good.
