Abstract

Le problème décrit par la présente invention est de fournir un ensemble d'administration de liquide médicinal pourvu d'un dispositif d'administration de liquide médicinal avec lequel une réduction de taille peut être obtenue, et avec lequel la consommation d'énergie dans un état de veille peut être supprimée. A Cet effet, l'invention concerne un ensemble d'administration de liquide médicinal 10 qui comprend : un dispositif d'administration de liquide médicinal 100 pourvu d'un récipient de liquide médicinal 110 rempli d'un liquide médicinal, un boîtier 120 retenant le récipient de liquide médicinal, un piston 130 pour pousser le liquide médicinal dans le récipient de liquide médicinal, un mécanisme d'entraînement 140 qui est logé dans le boîtier pour amener le piston à avancer vers un côté d'extrémité distale du récipient de liquide médicinal, une unité de source d'alimentation 170 qui est logée dans le boîtier pour fournir un courant d'entraînement au mécanisme d'entraînement, et un interrupteur magnétique à lames souples 150 qui est logé dans le boîtier et qui commute l'unité de source d'alimentation entre un état actif et un état inactif; et un aimant de commutation 300 capable de commuter l'interrupteur magnétique à lames souples entre un état excité et un état non excité.
