There is provided an extracorporeal circulation management device in which blood can be supplied in synchronization with heartbeats of a heart without using a plurality of devices and without causing damage to the blood.The extracorporeal circulation management device includes a flow rate information storage unit (31) that stores flow rate information acquired from a flow rate measurement unit (7), a candidate information generation unit (36) configured to identify systolic phase candidate information which may potentially correspond to systolic phase information on a heart and diastolic phase candidate information which may potentially correspond to diastolic phase information on the heart, based on information on comparison between a plurality of the flow rate information items acquired in time series, and a systolic-diastolic phase information generation unit (51) configured to identify the systolic phase information and the diastolic phase information in each heartbeat, based on information on appearance of a plurality of the systolic phase candidate information items and a plurality of the diastolic phase candidate information items acquired in time series,. Blood supply information for blood supply or blood supply stop information for stopping the blood supply is transmitted to a motor unit (4), based on the systolic phase information and the diastolic phase information.
