摘要
目的 观察2种消毒剂对救护车医疗舱空调排风管和医疗舱等环境消毒效果.方法 采用模拟现场消毒试验方法,对救护车空调通风管道和医疗舱内环境喷雾消毒效果进行观察.结果 在救护车空调通风管道和救护车医疗舱内,气溶胶喷雾器喷雾75 g/L浓度的过氧化氢消毒剂或200 mg/L有效氯的次氯酸消毒剂,密闭消毒作用30 min.过氧化氢消毒剂喷雾对不锈钢载体上金黄色葡萄球菌和大肠埃希菌的杀灭率均达到99.99%;次氯酸消毒剂喷雾对不锈钢载体上金黄色葡萄球菌和大肠埃希菌的杀灭率均>95%.结论 用过氧化氢消毒剂喷雾消毒对救护车空调管道和医疗舱内环境有较好的消毒效果,次氯酸消毒剂喷雾消毒效果低于过氧化氢消毒剂.
Abstract
Objective To observe the disinfection effect of two disinfectants on the air conditioning exhaust pipe and medical cabin environment of ambulance.Methods Simulated field disinfection test was used to observe the disinfection effect of spray on the air conditioning ventilation pipe and medical cabin environment of ambulance.Results The spray of hydrogen peroxide disinfectant with a concentration of 75 g/L or hypochlorite disinfectant with available chlorine of 200 mg/L was generated by aerosol sprayer to disinfect hermetically for 30 min in the air conditioning ventilation pipe and medical cabin environment of ambulance.The killing rate of Staphylococcus aureus and Escherichia coli on stainless steel carrier by hydrogen peroxide disinfectant spray reached 99.99%;The killing rate of Staphylococcus aureus and Escherichia coli on stainless steel carrier by hypochlorite disinfectant spray was about 95%.Conclusion Hydrogen peroxide disinfectant spray has a good disinfection effect on the air conditioning pipes and medical cabin environment of ambulance,and the disinfection effect of hypochlorite disinfectant spray is lower than that of hydrogen peroxide disinfectant.
