摘要
目的调查医疗机构口腔综合治疗台水路(DUWLs)回吸量,探讨影响DUWLs回吸的因素。方法采用系统随机抽样的方法对2014年5—11月天津市口腔综合治疗台(DCU)进行抽样,应用自行研制的回吸检测器对DUWLs回吸量进行检测,同时调查相关影响因素。结果共调查天津市10个区(县)30所医疗机构中58台DCU,平均DUWLs回吸量为(103.60±117.85)mm3,DUWLs回吸量合格率为48.28%(28/58);DCU已使用时间与DUWLs回吸量呈正相关(r=0.52,P<0.001)。不同医疗机构所属区县、医疗机构级别与类别、DCU品牌、DCU供水方式的DUWLs回吸量比较,差异均无统计学意义(均P>0.05)。结论 DUWLs回吸量检测合格率低,应加强DCU的日常维护与保养,尤其是使用时间长的DCU,应防止因防回吸阀门失效导致的DUWLs出水污染。
Objective To survey the retraction of dental unit waterlines (DUWLs)in medical institutions,and evaluate the influencing factors for retraction of DUWLs.Methods In May-November 2014,dental chair units (DCUs)in medical institutions in Tianjin City were sampled through systematic random sampling method,retrac-tion volume of DUWLs was detected by independently made detector,the relevant influencing factors were investi-gated.Results A total of 58 DCUs in 30 medical institutions in 10 districts(counties)of Tianjin were investigated, the average retraction volume of DUWLs was (103.60 ±117.85 )mm3 ,the qualified rate of retraction volume of DUWLs was 48.28 %(28/58);length of utilization of DCUs was positively correlated with DUWLs retraction (r=0.52,P 〈0.001).There were no significant difference in retraction volume of DUWLs among medical institutions in different districts(counties),levels of medical institutions,DUC brands,and modes of DUC water supply(all P 〉0.05 ).Conclusion The qualified rate of retraction volume of DUWLs is low,routine maintenance of DUCs needs to be intensified,especially the long-term used DUCs,contaminatin of DUWLs due to the invalidity of retraction valve should be prevented.
