CARDIOTHORACIC SURGERY SIMULATOR

Cardiothoracic surgery simulator. The invention relates to a cardiothoracic surgery simulator (100) comprising: - a cardiopulmonary block (10), with an inert heart and lungs; and, - a closed hydraulic circuit (11) to reproduce a part of a cardiovascular system, with a fluid reservoir (20) in fluid connection with a pumping element (30) configured to produce a continuous flow of said fluid from the reservoir (20) towards two circuits: - a main circuit (41) that passes through the cardiopulmonary block (10) with a first flow control element (V1) upstream of the cardiopulmonary block (10) and a second flow control element (V2) downstream of the cardiopulmonary block (10), this first main circuit returning to the fluid reservoir (20) downstream of the second flow control element (V2); - an auxiliary circuit (42), parallel to the main circuit (41) with return to the fluid reservoir (20) and comprising a third flow control element (V3); the cardiothoracic surgery simulator also comprising control means (50) configured: - to alternately act on the first flow control element (V1) and the third flow control element (V3) producing an alternating flow of fluid between the main circuit (41) and the auxiliary circuit (42); and - to act out of phase on the first flow control element (V1) and on the second flow control element (V2) producing a pressure pulse within the cardiopulmonary block (10); so that a pulsatile flow of the fluid is produced through the cardiopulmonary block (10).
