目的:调查和分析河北省医疗卫生系统生物安全柜防护性能现状,以加强实验室生物安全管理。方法:采用分层随机抽样方法对河北省的省、市和县级医疗卫生机构共计81台实验室生物安全柜进行现场检测,运用SPSS 18.0软件对检测数据进行统计分析。结果:在被检测的生物安全柜中噪声的合格率为98.77%,照度合格率为50.62%,洁净度和下降气流流速的合格率分别为53.09%和60.49%,高效过滤器完整性合格率为79.01%;常规进行年检的生物安全柜为0台。结论:所有被检测生物安全柜合格率偏低;生物安全柜未按标准进行年检。提示亟待加强生物安全柜的管理、维护和监督工作,推广操作技术规范。
Objective: To investigate and analyze the current status of protective performance of bio-safety cabinets in medical and health systems in Hebei Province so as to strengthen the management of bio-safety in laboratories. Methods: Stratified random sampling method was used to test 81 laboratory biosafety cabinets in provincial, city and county medical institutions in Hebei province. The data were analyzed by SPSS 18.0 software. Results: The qualified rate of noise in tested biological safety cabinets was 98.77%, the passing rate of illuminance was 50.62%, the pass rates of cleanliness and descending airflow rate were 53.09% and 60.49% respectively. The passing rate of high efficiency filter integrity was 79.01%, and there are 0 biological safety cabinets routinely carrying out annual inspection. Conclusion: All qualified biosafety cabinets have a low pass rate; biosafety cabinets fail to carry out annual inspection according to the standards. Prompt urgent need to strengthen the biological safety cabinet management, maintenance and supervision, promotion of operational specifications.
