Abstract
L'invention concerne un coeur artificiel électromécanique utilisant deux pompes aspirantes refoulantes à membranes ou diaphragmes, chaque pompe (41) étant constituée d'une chambre discoïde ou lenticulaire dont les bases de forme égale portent intérieurement une plaque de renfort (43), et sur la périphérie de laquelle sont reliés deux conduits, chacun avec un clapet de non-retour à ailettes souples, la chambre présentant une paroi qui fait office de support et une autre qui fait office de membrane, la membrane portant de manière adjacente, ou à l'intérieur, une plaque paramagnétique ou ferromagnétique, et déplaçant la plaque qui fait office de membrane actionnée ou déplacée par un électro-aimant auquel est appliqué un courant électrique sinusoïdal avec un oscillateur ou multivibrateur électronique créant une chambre à volume variable (41) et conjointement aux clapets à ailettes ou valves (22) dans les conduits périphériques. L'énergie électrique est appliquée sur la cage thoracique ou à l'extérieur au moyen de signaux radiofréquence, électromagnétiques, de flux magnétique avec des transformateurs ou avec des conducteurs électriques.
