| description | To provide a blood purification device capable of inhibiting blood from being condensed excessively with appropriate amounts of blood removal and blood reinfusion, and suppressing deterioration in removal substance removing efficiency in a single needle method.SOLUTION: A blood purifier 100 executes blood removal and blood reinfusion alternately with one puncture needle SN, and includes a blood circuit 110, a blood purifier 120 disposed in the blood circuit 110, blood concentration measuring means 150 for measuring the concentration of blood introduced to the blood purifier 120 or derived from the blood purifier 120, and control part 140 for executing control to perform a treatment process repeatedly including a blood removal process for introducing blood to the blood circuit 110 and a blood reinfusion process for deriving blood from the blood circuit 110. The control part 140 determines completion of the blood removal process on the basis of the concentration of the blood measured by the blood concentration measuring means 150, and sets an amount of blood to be reinfused in the blood reinfusion process on the basis of the amount of blood to be removed in the blood removal process.SELECTED DRAWING: Figure 1
【課題】シングルニードル法において、脱血量及び返血量を適切な量にすることで、血液が過度に濃縮することを抑制でき、かつ、除去物質の除去効率の低下を抑制できる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、１本の穿刺針ＳＮで脱血及び返血を交互に行う血液浄化装置１００であって、血液回路１１０と、血液回路１１０に配置される血液浄化器１２０と、血液浄化器１２０に導入又は血液浄化器１２０から導出される血液の濃度を測定する血液濃度測定手段１５０と、血液回路１１０に血液を導入する脱血工程と、血液回路１１０から血液を導出する返血工程と、を含む治療工程を繰り返し行うように制御する制御部１４０と、を備え、制御部１４０は、血液濃度測定手段１５０で測定される血液の濃度に基づいて、脱血工程の終了を判定し、脱血工程における血液の脱血量に基づいて、返血工程において返血する血液の返血量を設定する。【選択図】図１ |
