Abstract

L'invention concerne un dispositif permettant d'administrer des liquides, notamment des solutions de perfusion, et un appareil de chargement correspondant. Ce dispositif est caractérisé en ce qu'il comporte un mécanisme qui actionne un piston (3) avec une force exerçant une pression dans le sac (12) destiné à recevoir le liquide à administrer. L'invention vise à céder un volume de liquide constant par unité de temps pendant la durée du processus d'administration.
