Abstract: An imaging method for a catheter having a heart model, the heart model being installed in a container in a state of having the container filled with a liquid, and being provided with coronary arteries and an aorta. The imaging method includes causing a chemical reaction between an injection agent injected into the coronary arteries through a catheter, and the liquid in the container, and changing the color of the injection agent to the same color as that of the liquid.

Abstract: A pulsatile flow generating pump for a catheter simulator, which makes it possible to conveniently perform catheter operation training is provided.The pump (10) includes a cylinder (13) provided inside with a piston performing a reciprocating motion; a driving motor (15) causing the piston to perform a reciprocating motion; a link mechanism (19) converting the rotational motion of the driving motor (15) to the reciprocating motion of the piston; an extrusion port (86b), through which a liquid inside the cylinder is extruded to the outside by the piston; a suction port (86a), through which a liquid from the outside is sucked into the cylinder; and a control unit 70 for controlling the rotation of the driving motor 15. The control unit 70 controls the driving motor 15 so as to output pulsatile flows at a rate of 20 times to 200 times per minute.
