PROBLEM TO BE SOLVED: To provide an apparatus for continuous blood purification, when a flow path extending from a replenisher tank to a replenisher clamp is closed during operation of a replenisher pump, capable of stopping the replenisher pump at least at a stage where a retransfusion chamber is filled with the replenisher.SOLUTION: The apparatus for continuous blood purification includes a blood extracorporeal circulation circuit 10, a dialysate flow path 20, a replenisher flow path 30, a waste liquid flow path 40, capacitive measurement means, and a control part. The replenisher flow path 30 includes a replenisher tank 31, a replenisher clamp 32, and a replenisher pump 33 disposed therein. The replenisher flow path 30 between the replenisher clamp 32 and the replenisher pump 33 is connected with a replenisher branch flow path 35 in which a solenoid valve 36 for replenisher measurement, an upper replenisher level sensor 37, a replenisher measurement container 38, and a lower replenisher level sensor 39 are disposed. When the replenisher pump 33 is operated, if a state where the replenisher level is below the lower replenisher level sensor 39, is continued for a prescribed time, the control part outputs an alarm generation signal and a pump stop signal.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】補液ポンプの作動時に、補液タンクから補液クランプに至る流路が閉塞されたときに、少なくとも返血チャンバに補液が充たされている段階で補液ポンプを停止できる持続的血液浄化用装置を提供すること。【解決手段】血液体外循環回路10と透析液流路20と補液流路30と廃液流路40と容量式計量手段と制御部とを備え、補液流路30には補液タンク31と補液クランプ32と補液ポンプ33とが配置され、補液クランプ32と補液ポンプ33との間における補液流路30には、補液計量用電磁弁36と上側補液レベルセンサ37と補液計量容器38と下側補液レベルセンサ39とが配置されている補液分岐流路35が接続され、制御部は、補液ポンプ33の作動時に、下側補液レベルセンサ39より下方に補液液面が位置している状態が一定時間継続した場合に、警報発生信号およびポンプ停止信号を出力する。【選択図】 図1
