    • A body fluid treating circuit comprising a block for collecting a body fluid from a human body, a body fluid treating block and a block for returning the treated body fluid to the human body, said body fluid treating block comprising a plurality of treating units for treating the body fluid by passing therethrough, the units being arranged in parallel flow relationship, body fluid feed and return lines connected to each of the treating units so as to selectively feed to and return from the units through line switching means. The body fluid is treated using the above circuit by a method wherein the body fluid is fed to at least one first treating unit among a plurality of treating units to treat it up to a predetermined volume and the feeding is then switched to the residual second treating unit or units, the regeneration and washing of the first unit are conducted by successively feeding the regenerating liquid and washing liquid while treating the body fluid in the second unit, and after the completion of the treatment in the second unit, the body fluid feed line is switched to the regenerated and washed first unit with confirmation of the salt concentration of the effluent therefrom by the salt concentration measuring means in order to conduct the treatment in the first unit during which the regeneration and washing of the second unit are conducted, the above procedures being further repeated as occassion demands.
    • 一种体液治疗电路,其特征在于,包括用于从人体收集体液的体块,体液处理块和将经处理的体液返回到人体的块,所述体液处理块包括多个处理单元, 所述体液通过其中,所述单元以平行流动关系布置,体液供给和返回管线连接到每个处理单元,以便通过线切换装置选择性地进给和返回单元。 使用上述回路,通过以下方法对体液进行处理,其中将体液供给到多个处理单元中的至少一个第一处理单元以将其处理至预定体积,然后将进料切换至残余的第二处理 单元或单元,第一单元的再生和洗涤通过在对第二单元中的体液进行处理的同时依次供给再生液体和洗涤液,并且在第二单元中的处理完成之后,体液供给管线 切换到再生和洗涤的第一单元,通过盐浓度测量装置确认其流出物的盐浓度,以便在进行第二单元的再生和洗涤的第一单元中进行处理,上述 根据需要进一步重复程序。
