Abstract: A catheter simulator (10) of the invention has a container (20) filled with a liquid; an elastic heart model (30) installed in a floating state in the liquid with which the container (20) is filled; and a pump (50) connected to the heart model (30). The pump (50) is connected to an apex section of the heart model and produces a pulsatile flow from the apex section toward an aorta. Coronary arteries (33) provided on the surface of a main body (30A) of the heart model (30), pulsate together with the main body as a result of the pulsatile flow flowing from the pump (50).

Abstract: A heart model is retained in a container for a catheter simulator. The container includes an accommodating unit for accommodating a liquid, having side walls and a bottom surface, a connection unit attached to one of the side walls and retaining the heart model, and an installation part provided on one of the side walls. The installation part is configured to insert a catheter from an outside of the container into the simulated blood vessel of the heart model. The connection unit includes a holding protrusion protruding inside the accommodating unit, and a communicating hole. A front end of the holding protrusion is open so that the heart model is detachable from and reattachable to the holding protrusion by inserting and extracting a terminal of the heart model.
