Abstract[English]
The present disclosure relates to a monitoring unit (5) for a medicament delivery device (10) having a housing (4) enclosing a plunger rod and an electrically conductive helical torsion spring (3) for propelling said plunger rod, said monitoring unit (5) comprising a sensor (51) configured to detect changes in distance between the sensor (51) and the helical torsion spring (3) as the torsion spring (3) unloads and propels the plunger rod, and configured to correlate distance changes to a movement of the plunger rod.[French]
La présente invention concerne une unité de surveillance (5) pour un dispositif d'administration de médicament (10) ayant un boîtier (4) renfermant une tige de piston et un ressort de torsion hélicoïdal électriquement conducteur (3) pour propulser ladite tige de piston, ladite unité de surveillance (5) comprenant un capteur (51) configuré pour détecter les changements de distance entre le capteur (51) et le ressort de torsion hélicoïdal (3) lorsque le ressort de torsion (3) se détend et propulse la tige de piston, et configuré pour corréler les changements de distance à un mouvement de la tige de piston.
