Abstract[English]
A drug delivery device comprising a housing in which a spring base can be inserted, a drive member adapted to rotate a piston rod, and a helical drive spring having a distal end coupled to the drive member and a proximal end coupled to the spring base. The helical drive spring proximal end comprises a hook-formed portion arranged in a transversal plane, and the spring base comprises an axially oriented free edge adapted to engage the hook-formed portion, this allowing the hook-formed portion and the free edge to slide axially relative to each other.[French]
L'invention concerne un dispositif d'administration de médicament comprenant un boîtier dans lequel une base de ressort peut être insérée, un élément d'entraînement conçu pour faire tourner une tige de piston, et un ressort d'entraînement hélicoïdal ayant une extrémité distale accouplée à l'élément d'entraînement et une extrémité proximale accouplée à la base de ressort. L'extrémité proximale de ressort d'entraînement hélicoïdal comprend une partie en forme de crochet disposée dans un plan transversal, et la base de ressort comprend un bord libre orienté axialement conçu pour venir en prise avec la partie en forme de crochet, ce qui permet à la partie en forme de crochet et au bord libre de coulisser axialement l'un par rapport à l'autre.
