摘要
目的:建立2019冠状病毒病(COVID-19)疫情期间医用正压送风过滤式防护头罩再处理流程,确保头罩复用处理的消毒效果和质量。方法:建立消毒供应中心对医护人员救治COVID-19患者过程中使用的正压送风过滤式防护头罩的预处理和暂存流程、消毒供应中心回收流程、头罩清洗消毒及灭菌处理流程。采用放大镜目测法、蛋白清洗测试棒检测法、实时荧光聚合酶链反应法、琼脂倾注培养,分析经过处理后正压送风过滤式防护头罩清洗消毒效果。结果:25件正压送风过滤式防护头罩共经过135件次清洗消毒和灭菌处理,清洗后蛋白质残留量检测、病毒核酸检测均为阴性;灭菌后物品无菌性检测合格,头罩无损伤,质量安全可靠。结论:采用使用科室预处理、消毒供应中心集中清洗消毒及环氧乙烷灭菌流程对救治COVID-19患者使用后的正压送风过滤式防护头罩进行复用处理是安全可行的。
Objective:To establish reuse process of positive pressure powered air-filter protective hoods during coronavirus disease 2019(COVID-19)epidemic.Methods:The procedure of pretreatment,storage,recovery,cleaning,disinfection and sterilization process of positive pressure powered air-filter protective hoods,which were used in the treatment of COVID-19 infection patients was established in Central Sterile Supply Department of the hospital.The cleaning and disinfection effects of the protective hoods after treatment were examined by magnifying glass method,residual protein detection method,real-time PCR,and agar pour plate method.Results:Twenty five used protective hoods underwent totally 135 times of washing,disinfecting and sterilizing procedures.After washing,all the protein residue tests and COVID-19 nucleic acid tests showed negative results.After sterilizing,all the protective hoods met sterility requirement.All the tested protective hoods were undamaged after reprocessing.Conclusion:The established reuse procedures for used positive pressure powered air-filter protective hoods are safe.
