Low-fidelity simulator for technical connection to the cardiopulmonary bypass

The technical simulator proposed in this study is a low-cost, reusable, reproducible and portable tool to guide trainees at all levels in order to improve their surgical skills in connection with the cardiopulmonary bypass (CPB) circuit. The simulator is a self-made portable box that can be used for an unrestricted number of procedures. It is supplied with self-made anatomical replicas that have been tested to simulate the flexible property of the real anatomy. The building process is detailed in this study.
