摘要
目的 观察生物安全实验室感染性废物处置过程中包装物对灭菌质量的影响因素.方法 采用生物和化学监测法,对生物安全实验室感染性废物包装物影响压力蒸汽灭菌效果的风险因素进行观察与分析.结果 实验室内感染性废物采用单层封口外包装比单层敞口外包装灭菌更难;细胞培养瓶、利器盒和采样管的灭菌难度依次递增;采用双层封口外包装的采样管很难灭菌.结论 生物安全实验室感染性废物进行压力蒸汽灭菌时,宜采用单层外包装,封装时留出排气口以确保灭菌质量.
Abstract
Objective To observe the influencing factors of packaging materials on sterilization quality during the disposal of infectious waste in biosafety laboratories.Methods Biological and chemical monitoring methods were used to observe and analyze the risk factors affecting the pressure steam sterilization effect of infectious waste packaging materials in biosafety laboratories.Results It was more difficult to sterilize infectious waste using single-layer sealed packaging than single-layer open packaging in laboratories.The difficulty of sterilization of cell culture flasks,sharps boxes,and sampling tubes increased sequentially.Sampling tubes with double-layer sealed outer packaging were difficult to be sterilized.Conclusion When pressure steam sterilization is performed on infectious waste in biosafety laboratories,a single-layer outer packaging should be used,and the exhaust port should be left during packaging to ensure sterilization quality.
