Document Type and Number:
WIPO Patent Application WO/2018/180043
Kind Code:
A1
Abstract:
Provided is a blood purification device in which an infusion line for supplying an infusion of an anticoagulant or the like is connected to a blood removal line, wherein blood can be returned automatically without the need to reverse the rotation of a blood pump and without the need to provide an infusion supply means for retransfusion to a downstream side of the blood pump. A control unit 80 of a blood purification device 1: stops operation of a blood pump 30 and infusion pump 52, and opens a first infusion line 40 with a first on/off valve 42 and closes a blood removal line 10 with a second on/off valve 11; rotates the blood pump 30 forward by a predetermined amount X, and causes a first infusion to move from the first infusion line 40 to the blood removal line 10; rotates the infusion pump 52 backward by a predetermined amount Y, and causes the first infusion in the blood removal line 10 to move to a second infusion line 50; closes the first infusion line 40 with the first on/off valve 42 and opens the blood removal line 10 with the second on/off valve 11; and rotates the infusion pump 52 forward by a predetermined amount Z, and causes the first infusion in the second infusion line 50 to move to the blood removal line 10 and return to a patient P. Due to this configuration, automatic retransfusion to the patient P can be achieved.
