Title (EN) DEVICE FOR AUTOMATICALLY INJECTING LIQUID PRODUCT COMPRISING AN INJECTION SPRING
(FR) DISPOSITIF D'INJECTION AUTOMATIQUE DE PRODUIT LIQUIDE COMPRENANT UN RESSORT D'INJECTION
Abstract:
(EN) The automatic injection device comprises an injection spring (24) that is deformable between a compressed state prior to use of the automatic injection device and a relaxed state after injection. It comprises a plunger control member (22) configured to apply a force to a plunger (40) under the action of the injection spring (24) in order to allow the plunger (40) to move in the distal direction of the automatic injection device. The plunger control member (22) bears a stop (118) that is retractable between an active configuration in which it retains the injection spring (24) in the compressed state and a retracted position in which it releases the injection spring (24). The automatic injection device also comprises a locking member (122) for locking the retractable stop (118) in its active configuration, this locking member (122) being able to adopt a locking position in which it applies pressure to the retractable stop (118) to prevent it from adopting its retracted configuration, and an unlocking position in which the retractable stop (118) is released.
(FR) 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.
