Abstract

Un dispositif d'actionnement (100) ayant un piston intégré est configuré pour être monté de façon amovible sur un dispositif de mélange automatique pour une seringue. Le dispositif d'actionnement comprend des boîtiers inférieur (180) et supérieur (110), un élément de déclenchement (120), un anneau de verrouillage (170), un élément de sollicitation de mélange (150), un piston de distribution (1300), un élément de sollicitation de piston et un piston de mélange (140). Le piston de mélange (130) est en prise de manière libérable avec l'élément de déclenchement (120) dans un état initialement verrouillé et peut venir en prise avec au moins un joint d'étanchéité (250) du dispositif de mélange. L'élément de déclenchement est utilisable pour initier la décompression de l'élément de sollicitation de mélange (150) et la mise en prise du piston de mélange avec le ou les joints d'étanchéité (250) du dispositif de mélange. Le piston de distribution peut également être activé pour se dilater à partir d'une première configuration repliée (fig. 6A) jusqu'à une seconde configuration dilatée (fig. 6B) par actionnement de l'élément de déclenchement (120).
