PROBLEM TO BE SOLVED: To provide a blood purification device which enables the device constitution thereof to be simplified and an increase in the manufacturing cost thereof to be avoided and which can easily lower temperature of a dialysis solution in a short period of time when the dialysis solution reaches excessive temperature.SOLUTION: The blood purification device is provided that comprises: a blood circuit 1 a dialyzer 2 a dialysis solution introduction line L1 and a dialysis solution discharge line L2 a blood pump P1, a solution feed pump P2, and a filtration pump P3 and control means 9. When temperature of the dialysis solution detected by temperature detection means T is equal to or higher than a predetermined value, the control means 9 causes the dialysis solution in heating means h to flow to an upstream side or a downstream side of the heating means h by the solution feed pump P2 without introducing the dialysis solution to the dialyzer 2.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】装置構成の簡素化及び製造コストの上昇を回避することができるとともに、透析液が過温度となった際、より短時間且つ容易に透析液の温度を低下させることができる血液浄化装置を提供する。【解決手段】血液回路1と、ダイアライザ2と、透析液導入ラインL1及び透析液排出ラインL2と、血液ポンプP1、送液ポンプP2及び濾過ポンプP3と、制御手段9とを具備した血液浄化装置において、温度検出手段Tで検出された透析液の温度が所定値以上の場合、ダイアライザ2に透析液を導入することなく、送液ポンプP2にて加温手段hにおける透析液を当該加温手段hの上流側又は下流側まで流動させ得る制御手段9を具備したものである。【選択図】図1
