摘要

目的检测移位后脉动预真空灭菌器的运行状态是否正常。方法采用温度压力检测仪和化学、物理、生物监测方法检测灭菌器的运行状态,对检测不合格灭菌器进行维修,监测移装后灭菌器运行状态直至各项指标合格。结果移装的4台灭菌器中,2、3、4号灭菌器的运行状态良好,1号灭菌器存在问题。移装前1号灭菌器物理监测、生物监测和管腔PCD检测合格,6类PCD、B-D测试发现灭菌器故障,温度压力检测仪检测也不合格。灭菌器厂家和温度压力检测厂家工程师共同查找原因,经过3次报修后,最后通过提高灭菌器的灭菌温度和压力,灭菌器检测参数明显改善且合格,最终将1号灭菌器调整至最佳运行状态。结论除常规监测外,依据标准WS310.3—2016使用温度压力检测仪对灭菌器进行温度、压力和时间等参数进行检测是十分必要的,同时新装、移位、大修后同样应使用温度压力检测仪对灭菌器进行检测。
        Objective To check whether the status of performance operation of pre-vacuum team sterilizers is normal after displacement.Methods The temperature and pressure detector as well as chemical,physical,and biological monitoring methods were used to evaluate the operating status of sterilizers,the unqualified sterilizers were repaired and operation status of sterilizers after loading was monitored until all indicators shown as qualified.Results Among the four sterilizers that were moved,sterilizers No.2,3,and 4 were in good working condition,while sterilizer No.1 had problems.The physical,biological monitoring,and lumen process challenge device(PCD)detection in sterilizer No.1 before loading were qualified,the sterilizer fault was found by PCD(type 6)and B-D tests,temperature and pressure detector failed to pass the test.The potential causes of failures were examined by the engineers from the manufacturers of sterilizer as well as temperature and pressure detector.After three repairs,sterilization temperature and pressure of sterilizers were improved,sterilizer detection parameters were significantly improved and became qualified,the No.1 sterilizer was finally adjusted to the optimum operating state.Conclusion In addition to routine monitoring,it is necessary to use temperature and pressure detector to measure the temperature,pressure,and time of sterilizer according to the Standard WS 310.3-2016.At the same time,it is also recommended to use the temperature and pressure detector as mandatory procedure after each new installation,displacement and overhaul of the sterilizer.
