The invention relates to a dialysis device (1) having a dialysate circuit comprising a first dialyzer (3) and a second dialyzer (5) wherein the first dialyzer (3) is connectable to a blood circulation of a patient via a blood feed line (11) and a recirculation (13), an effluent for a retentate flow (Qeffluent) from the dialysate circuit to the second dialyzer (5) is provided and a permetate stream (Qout) of the second dialyzer (5) in the dialysate circuit is passed to the first dialyzer (3), the second dialyzer (5) comprising a filter membrane having a cut-off value of at least 500 Da and the first dialyzer (3) comprising a filter membrane having a cut-off value exceeding that of the second dialyzer (5).本發明是有關於一種具有一透析液回路的透析裝置,該透析液回路包含有一第一透析器以及一第二透析器,其中該第一透析器可經由一血管輸送以及一回送而與一患者的血液循環連通,在該第二透析器處設置有從該透析液回路中排出一滯留液流(Qeffluent)並且將該透析液回路中的該第二透析器之一通透液流(Qout)引導至該第一透析器。而且該第二透析器包含有一帶有截斷值為至少500 Da的濾膜而該第一透析器包含有一帶有要比該第二透析器還高的截斷值的濾膜。1...透析裝置3...第一透析器5...第二透析器7...血液室9...透析液室11...血管輸送13...回送15...導管17...進入室19...過濾室21...泵23...導管25...供應設備QB...血流QD...透析液流Qfeed...透析液代用品Qeffluent...滯留液排出Qout...通透液流Qin...過濾輸送
