目的通过归纳分析一种进口蒸汽灭菌器使用中的故障,确定维护、保养重点,降低设备故障率,提高灭菌效果,为灭菌器的检修和管理提供参考。方法根据6台蒸汽灭菌器的维修记录,分类统计2012年12月-2015年12月发生故障事件及处理情况,分析故障发生原因。结果使用3年共计114例故障中,与水质、水压相关故障占27%,开关门故障占21%,BD测试失败占8.8%,预热时间长占8.8%,LCS 8535软件连接不上占7%,灭菌器运行超时占总8.8%,其他故障占7.8%。其中第一年故障率最高,导致故障率高原因并非设备本身因素,主要是供水与人员因素。结论在导致灭菌器故障的诸多因素中,灭菌水质是主要因素,其次是设备本身及人员因素,应加强灭菌用水管理、设备管理和操作人员培训。
Objective To summarize the faults in the use of an imported steam sterilizer, determine the main points of maintenance and maintenance, reduce the equipment failure rate and improve the sterilization effect, and provide a reference for the maintenance and management of the sterilizer. Methods Based on the maintenance records of 6 steam sterilizers, the breakdown events and their treatment from December 2012 to December 2015 were classified and the causes of the failure were analyzed. Results A total of 114 failures occurred in 3 years, accounting for 27% of faults related to water quality and water pressure, 21% of failures of opening and closing doors, 8.8% of failed BD tests and 8.8% of warm-up time. LCS 8535 software connection was not accounted for 7%, sterilizer operation overtime accounted for 8.8%, other failures accounted for 7.8%. One of the highest failure rate in the first year, resulting in a high failure rate is not the equipment itself, the main factor is the water supply and personnel. Conclusion Sterilization water quality is the main factor among the many factors leading to sterilizer failure, followed by the equipment itself and staffing factors. Sterilization water management, equipment management and operator training should be strengthened.
