Abstract

See full text

An artificial heart and lung apparatus (100) includes a roller pump (120); a blood removal line (101); a first blood transfer line (104); a blood removal rate sensor (111); a control unit (140) that performs the linked control of the roller pump (120) in correspondence with a blood removal rate; and a blood transfer rate adjustment unit (160) that instructs the roller pump (120) to transfer a blood transfer rate. The blood transfer rate adjustment unit (160) includes an operation amount input unit to which an operation amount from an arbitrary circumferential position can be input, and which outputs a pulse signal according to the input operation amount, and a counter that adds and subtracts pulse signals output from the operation amount input unit, and outputs a resultant as blood transfer rate adjustment data, and the counter performs a counting operation with respect to the circumferential position of the operation amount input unit when blood transfer control transitions to the normal control.
