| Zusammenfassung: | To provide a CRRT system capable of reducing influence of pressure that the CRRT system receives from an ECMO system when the CRRT system is connected to the ECMO system.SOLUTION: A CRRT system 200 includes: a blood removal line 210 whose upstream end is connected to a downstream side of a blood pump of an ECMO system; a blood purifier 220 connected to a downstream end of the blood removal line; a flow rate adjustment part 211 provided for the blood removal line; a blood reinfusion line 230 whose upstream end is connected to the blood purifier 220 and whose downstream end is connected to the ECMO system; a blood reinfusion pump 231 provided for the blood reinfusion line; and a manometer P3 measuring pressure on the upstream side of the blood reinfusion pump. It is controlled so that flow rates of the flow rate adjustment part 211 and the blood reinfusion pump 231 are adjusted and measurement value of the manometer P3 is within a prescribed range.SELECTED DRAWING: Figure 1
【課題】ＥＣＭＯシステムにＣＲＲＴシステムを接続する場合に、ＣＲＲＴシステムがＥＣＭＯシステムから受ける圧力の影響を低減可能なＣＲＲＴシステムを提供する。【解決手段】ＣＲＲＴシステム２００は、上流端がＥＣＭＯシステムの血液ポンプよりも下流側に接続される脱血ライン２１０と、脱血ラインの下流端に接続される血液浄化器２２０と、脱血ラインに設けられる流量調整部２１１と、上流端が血液浄化器２２０に接続され下流端がＥＣＭＯシステムに接続される返血ライン２３０と、返血ラインに設けられる返血ポンプ２３１と、返血ポンプよりも上流側の圧力を測定する圧力計Ｐ３と、を備え、流量調整部２１１及び返血ポンプ２３１の流量を調整して、圧力計Ｐ３の測定値が所定の範囲内となるように制御する。【選択図】図１ |
