    摘要:

    目的 调查新建内镜中心验收过程中发现的纯水系统菌落数超标原因,并给予解决方案。 方法 采集纯水制备与使用的所有环节水样,明确细菌超标原因,根据原因制定处置措施,并监测强化消毒效果维持时间。 结果 排查后推断纯水箱出水口至进入内镜洗消设备前,新铺设的输水管道为此次细菌超标的主要原因,根据原因采取管路改造、增加消毒设施、对输水管道和洗消设备清洗消毒等组合处置措施。综合干预后各个采样点均未再检出细菌,内镜中心顺利投入使用,并确定水路强化消毒间隔时间为12周。 结论 新建内镜中心启用前的验收工作非常重要,新纯水管道需在铺设之前进行冲洗,以保证终末漂洗水质量。

    Abstract:

    Objective To investigate the causes for number of bacterial colonies exceeding the standard in the pure water system found during the acceptance of newly built endoscopy center, and put forward solutions. Methods Water specimens were collected from all steps of pure water preparation and use, the causes for number of bacterial colonies exceeding the standard were identified, disposal measures according to the causes were formulated, and the maintenance time of intensive disinfection effect was monitored. Results The investigation result inferred that the newly laid water pipeline between the outlet of pure water tank and inlet of the endoscope before entering the endoscopic decontamination equipment is the main cause for the bacteria exceeding the standard. According to the causes, combined disposal measures such as pipeline transformation, adding disinfection facilities, cleaning and disinfection of water pipeline and decontamination equipment are formulated. After comprehensive intervention, no bacteria were detected at each sampling point, the endoscopy center was successfully put into use, and the interval of waterline intensive disinfection was determined to be 12 weeks. Conclusion The acceptance before operation of the newly built endoscope center is very important, the new pure water pipeline needs to be flushed before laying to ensure the quality of final rinsing water.
