To provide a blood purification device capable of measuring blood recirculation easily at low cost.SOLUTION: A blood purification device 100 includes: a blood purifier 120; an artery side line 111; a vein side line 112; replacement fluid injection means for injecting replacement fluid to the artery side line 111 or the vein side line 112; artery side measuring means 111M provided to the artery side line 111 for measuring a blood state; and a control unit 140 for controlling the replacement fluid injection means and the artery side measuring means 111M. The control unit 140 measures blood recirculation on the basis of a change in the blood state measured by the artery side measuring means 111M in a state in which the replacement fluid is injected by the replacement fluid injection means.SELECTED DRAWING: Figure 3 【課題】血液再循環を少ないコストで容易に測定可能な血液浄化装置を提供すること。【解決手段】血液浄化装置１００は、血液浄化器１２０と、動脈側ライン１１１と、静脈側ライン１１２と、動脈側ライン１１１又は静脈側ライン１１２に補液を注入する補液注入手段と、動脈側ライン１１１に設けられ、血液の状態を測定する動脈側測定手段１１１Ｍと、補液注入手段及び動脈側測定手段１１１Ｍを制御する制御部１４０と、を備え、制御部１４０は、補液注入手段により補液が注入されている状態において、動脈側測定手段１１１Ｍにより測定される血液の状態の変化に基づいて、血液再循環を測定する。【選択図】図３
