Abstract[English]
Medicament delivery device comprising: a housing a plunger rod, and a drive spring, a needle cover, and a needle cover spring, an activator, fixed relative to the housing, wherein the outer surface of plunger rod comprises a proximal, an intermediate and a distal recess, wherein the activator comprises at least one proximal and at least one distal arm both flexible radially, and wherein the medicament delivery device is such that: in an initial configuration, the distal arm is constrained in the intermediate recess by the needle cover, in a second configuration, the proximal arm is constrained in the proximal recess by the needle cover, allowing only a limited movement of the plunger rod for priming, in a third configuration, the proximal arm is no longer constrained, and the distal arm is constrained in the distal recess, allowing the rest of the movement of the plunger rod.[French]
Dispositif d'administration de médicament comprenant : un boîtier, une tige de piston, et un ressort d'entraînement, un couvercle d'aiguille et un ressort de couvercle d'aiguille, un activateur, fixé par rapport au boîtier, la surface externe de la tige de piston comprenant un évidement proximal, un évidement intermédiaire et un évidement distal, l'activateur comprenant au moins un bras proximal et au moins un bras distal tous deux flexibles radialement, et le dispositif d'administration de médicament étant tel que : dans une configuration initiale, le bras distal est contraint dans l'évidement intermédiaire par le couvercle d'aiguille, dans une deuxième configuration, le bras proximal est contraint dans l'évidement proximal par le couvercle d'aiguille, permettant uniquement un mouvement limité de la tige de piston pour l'amorçage, dans une troisième configuration, le bras proximal n'est plus contraint, et le bras distal est contraint dans l'évidement distal, permettant le reste du mouvement de la tige de piston.
