【摘要】 目的 了解北京市医疗卫生机构Ⅱ级生物安全柜性能及其影响因素，为实施精细化管理提供参考。方法采用仪器测试法，对北京市39家医疗卫生机构Ⅱ级生物安全柜性能指标进行检测与分析。结果 共检测国产和进口生物安全柜309台，综合指标合格率为61.2%，国产与进口产品性能指标基本一致。使用年限10年以下的A2型生物安全柜的综合指标合格率较高。影响生物安全柜合格率的主要因素为未配备性能检测相关设备、专业人员巡检不足和未安排专业检测机构年检。结论 北京市医疗卫生机构国产和进口生物安全柜综合指标合格率相当，可适当增加国产生物安全柜配置，加强生物安全柜监督监测和提高安全防护性能。更多还原

【Abstract】 Objective To understand the performance of Class Ⅱ biological safety cabinets and its influencing factors in medical and health institutions in Beijing, and to provide reference for implementing refined management.Methods The instrument testing method was used to detect and analyze the performance indicators of Class Ⅱbiological safety cabinets in 39 medical and health institutions in Beijing. Results A total of 309 domestic and imported biological safety cabinets were tested, with a comprehensive qualified rate of 61.2%. The performance indicators of domestic and imported products were basically the same. The comprehensive qualified rate of A2 type biological safety cabinets with a service life of less than 10 years was relatively high. The main factors affecting the qualified rate of biological safety cabinets were the lack of performance testing equipment, insufficient professional personnel inspections, and the absence of professional testing institutions for annual inspections. Conclusions The comprehensive qualified rate of domestic and imported biological safety cabinets in medical and health institutions in Beijing is comparable, and the configuration of domestic biological safety cabinets should be increased. Therefore,it is necessary to strengthen the supervision and monitoring of biological safety cabinets and improve their safety protection performance.更多还原
