PROBLEM TO BE SOLVED: To provide a blood purification device capable of avoiding an increase in the size of index detection means, and capable of detecting a state in which a flow channel composing a blood circuit is not attached to index detection means with a high degree of precision.SOLUTION: A blood purification device has a dialyzer 3 for purifying blood that flows through the blood circuit, and a squeezing pump for squeezing part of an artery side blood circuit in a solution sending direction, and includes a blood pump 4 for causing the blood to flow from the tip of the artery side blood circuit 1 to the tip of a vein side blood circuit 2 by driving, and index detection means 10 attached to a predetermined position of the blood circuit for detecting a predetermined index of the blood that flows through a flow channel at the predetermined position. While the blood pump 4 is driven to cause the solution to flow in the blood circuit, a change in a detection value of the index detection means 10 is detected so that whether or not the blood circuit is attached to the index detection means 10 is determined.COPYRIGHT: (C)2016,JPO&INPIT【課題】指標検出手段の大型化を回避できるとともに、血液回路を構成する流路が指標検出手段に取り付けられていない状態を精度よく検出することができる血液浄化装置を提供する。【解決手段】当該血液回路を流れる血液を浄化するダイアライザ3と、動脈側血液回路の一部を送液方向に扱くしごき型ポンプから成り、駆動によって動脈側血液回路1の先端から静脈側血液回路2の先端まで血液を流動させ得る血液ポンプ4と、血液回路の所定位置に取り付けられ、当該所定位置の流路を流れる血液の所定指標を検出し得る指標検出手段10とを具備した血液浄化装置において、血液ポンプ4を駆動させて血液回路にて液体を流動させつつ指標検出手段10の検出値の変化を検出することにより、指標検出手段10に血液回路が取り付けられているか否かを判定し得るものである。【選択図】図1
