To prevent bubbles from being injected into a patient without using tube clamping means.SOLUTION: An extracorporeal circulation treatment device is provided that comprises: a device body including an arterial blood circuit and a venous blood circuit, and provided with a blood circuit for extracorporeally circulating patient's blood from the distal end of the arterial blood circuit to the distal end of the venous blood circuit; and a blood pump of a tube pump type for wiping a wiper part arranged in a portion of the arterial blood circuit, and causing the blood in the blood circuit to flow. The extracorporeal circulation treatment device further comprises: an arterial bubble detector arranged in the arterial blood circuit and monitoring an amount of cumulative bubbles; and a control unit controlling to stop the blood pump when the immixing of the bubbles in an amount equal to or more than a first predetermined value is detected by the arterial bubble detector.SELECTED DRAWING: Figure 1 【課題】チューブクランプ手段を用いることなく気泡が患者に注入されるのを防止する。【解決手段】動脈側血液回路及び静脈側血液回路を有すると共に前記動脈側血液回路の先端から前記静脈側血液回路の先端まで患者の血液を体外循環させる血液回路が備えられる装置本体と、前記動脈側血液回路の一部に配設されたしごき部をしごいて前記血液回路内の血液を流動させるチューブポンプ型の血液ポンプとを備える体外循環治療装置であって、前記動脈側血液回路に配設され累積の気泡量を監視する動脈側気泡検出器と、前記動脈側気泡検出器により第一の所定値以上の気泡量の混入が検出された場合に、前記血液ポンプを停止させる制御を行う制御部とを備える。【選択図】図１
