PROBLEM TO BE SOLVED: To provide a blood circulation system capable of stably sending blood and efficiently circulating the blood in the blood circulation system.SOLUTION: An artificial heart-lung apparatus 100 comprises: a roller pump 120; a blood removal line 101; a first blood transmission line 104; a blood removal flow-rate sensor 111; and a control unit 140 carrying out tandem control of the roller pump 120 in association with the blood removal flow rate; and a blood transmission flow-rate adjusting unit 160 for giving blood transmission flow-rate instructions to the roller pump 120. The blood transmission flow-rate adjusting unit 160 includes: an operation amount input unit into which an operation amount can be input from a discretionary position in a circumferential direction, and which outputs a pulse signal in accordance with the input operation amount; and a counter that performs addition or subtraction on the pulse signal output by the operation amount input unit and outputs such results as blood transmission flow-rate adjustment data. The counter carries out counting with the reference therefor being the circumferential direction position of the operation amount input unit when the unit is transitioned to normal control.SELECTED DRAWING: Figure 1 |
