摘　　要：本文对长沙市部分透析单位的透析用水及透析液质量的状况进行了调查,从内毒素、游离氯、硬度测试三方面检测、分析,提出改善透析用水的质量的办法,以及透析用水、透析液的卫生质量与水处理系统使用时间和反渗膜、活性炭、软水器及时更换、定期维护及管路消毒与更换,与管路设计有无死腔、有无储水罐等得关系。以进一步提高长沙市透析单位透析用水及透析液的质量。Objective To research the effect of reverse osmosis membrane and pipeline in water treatment system.Methods A formal questionnaire was prepared and accounted in 20 hospitals＇ Hemodialysis Centers in 2006 in Changsha.Four points of hemodialysis water of water treatment system were selected,which not only acquired easily but also represent polluted situation：tap water,reverse osmosis water 1（prepare B fluid sampling point）,reverse osmosis water 2（go into dialysis machine sampling point）,dialyser entrance dialysate sampling point,to detect endotoxin.Results The sanitary quality of the dialysate in hospitals was associated with the using time of water system,timely exchange and disinfection of the water treatment system,whether there were deep space and water storage tank in the channel design.Conclusion Double osmosis systems were superior to one osmosis systems in Hemodialysis system of water treatment system.
