Abstract

L'invention porte sur une pompe péristaltique comportant un conduit souple (2) de fluide et une série de paires d'éléments de compression (10) se faisant mutuellement face et disposés extérieurement le long du conduit (2). Une stimulation électrique progressive des paires d'éléments pouvant consister en des cellules souples remplies d'un gel de polymère à propriétés piézo-électriques produit une compression péristaltique (13) le long du conduit. Un moyen d'expansion radiale sous forme d'un tube en spirale (6) rempli d'un gaz ou d'un gel de polymère approprié peut être activé pour dilater sélectivement le conduit (2) après le passage d'une onde de compression. Le tube en spirale est divisé par exemple toutes les quatre spires en segments de manière à optimiser les caractéristiques de dilatation. Le conduit (2) présente une section elliptique à l'état relâché, ce qui correspond à la configuration dudit conduit à mi-chemin de la phase de compression.
