Abstract

On décrit un dispositif de détection de dose d'injection qui comprend: un boîtier (110); un bouton (120) relié au boîtier (110); un circuit de commande (130) comprenant un interrupteur de fin de course (132) et un codeur rotatif (134) en liaison électrique avec l'interrupteur de fin de course (132); un module de rotation (140) relié rotatif au codeur rotatif (134); et une unité de raccordement (150) servant à raccorder le module de rotation (140) à un bouton de réglage de dose d'injection (210) d'un stylo injecteur (200). Une pression exercée sur le bouton (120) déclenche l'interrupteur de fin de course (132) qui amène le codeur rotatif (134) à commencer à détecter le degré de rotation du bouton de réglage de dose d'injection (210). Sans pression sur le bouton (120), l'interrupteur de fin de course (132) n'est pas déclenché et le codeur rotatif (134) cesse de détecter le degré de rotation du bouton de réglage de dose d'injection (210). Le circuit de commande (130) génère en outre un message de dosage d'injection en fonction du degré de rotation du bouton de réglage de dose d'injection (210) détecté par le codeur rotatif (134).
