Title
(EN) ASSEMBLY FOR A DRUG DELIVERY DEVICE
(FR) ENSEMBLE POUR UN DISPOSITIF D'ADMINISTRATION DE MÉDICAMENT
Abstract
(EN) An assembly (30) for a drug delivery device (1) is provided, wherein the assembly comprises an actuator (16) which is configured to perform a setting movement in order to set a dose and which is configured to perform a dispense movement in order to dispense a dose and a piston rod (10) which is configured to be moved in a distal direction in order to dispense a dose, and a snap feature (31) which is configured to snap into engagement with the piston rod (31). The snap feature (31) may be configured to inhibit a dispense movement of the actuator (16) and/or a setting movement of the actuator (16) when a maximum amount of medication has been delivered.
(FR) L'invention concerne un ensemble (30) pour un dispositif d'administration de médicament (1), l'ensemble comprenant un actionneur (16) qui est configuré pour exécuter un mouvement de réglage de façon à régler une dose et qui est configuré pour exécuter un mouvement d'administration de façon à administrer une dose, et une tige de piston (10) qui est configurée pour se déplacer dans une direction distale de façon à administrer une dose, et un élément d'encliquetage (31) qui est configuré pour encliqueter et s'accoupler à la tige de piston (31). L'élément d'encliquetage (31) peut être configuré pour empêcher un mouvement d'administration de l'actionneur (16) et/ou un mouvement de réglage de l'actionneur (16) lorsqu'une quantité maximale de médicament a été administrée.
