BLOOD FEEDING FLOW RATE-CONTROLLING DEVICE AND EXTRACORPOREAL CIRCULATION DEVICE

摘要

A blood supply flow rate controlling device (2), which is a device for controlling the blood supply flow rate in an extracorporeal circulation device connected to a living body (10), includes rotational frequency detecting means that detects the rotational frequency of the centrifugal pump (40) of the extracorporeal circulation device, inlet pressure detecting means and outlet pressure detecting means that detect the inlet pressure and the outlet pressure of the centrifugal pump (40), respectively, flow rate regulating means that regulates a flow rate of blood supplied to the living body by adjusting a flow path cross section area of the blood circulation circuit (20), and controlling means that controls the flow rate regulating means.
