Abstract: A cardiac function measuring system 200 includes a flowmeter 70 that measures a flow rate waveform of blood from a human body while the blood is circulating outside the body in an extracorporeal circulator. A control unit 100 acquires a pulsation waveform 62 (waveform 60) which is a flow rate fluctuation waveform of blood included in a flow rate waveform measured by the flowmeter 70. A display unit 30 displays a pulsation waveform indicating a cardiac function of a human body in response to a command from the control unit 100.

Abstract: A procedure simulator that includes an animal heart to which a first balloon is inserted into a left ventricle of the heart and to which a second balloon is inserted into a right ventricle of the heart. A pump system makes the first balloon and the second balloon expand and contract via an operating fluid (L). A blood supply unit then directly supplies blood to three coronary arteries of the heart while the balloons are expanding and/or contracting.
