Abstract

Le dispositif d'injection automatique comprend un ressort d'injection (24), déformable entre un état comprimé avant utilisation du dispositif d'injection automatique et un état détendu après injection. Il comprend un organe de commande de piston (22), configuré pour appliquer une force sur un piston (40) sous l'action du ressort d'injection (24) pour permettre le déplacement du piston (40) dans la direction distale du dispositif d'injection automatique. L'organe de commande de piston (22) porte une butée (118) escamotable entre une configuration active de retenue du ressort d'injection (24) à l'état comprimé et une configuration escamotée de libération du ressort d'injection (24). Le Dispositif d'injection automatique comprend également un organe de verrouillage (122) de la butée escamotable (118) dans sa configuration active, cet organe de verrouillage (122) pouvant prendre une position de verrouillage, dans laquelle il exerce une pression sur la butée escamotable (118) pour l'empêcher de prendre sa configuration escamotée, et une position de déverrouillage dans laquelle la butée escamotable (118) est libérée.
