Abstract
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 theref…
