Title (EN) A TORSION SPRING DRIVEN INJECTION DEVICE
(FR) DISPOSITIF D'INJECTION ENTRAINÉ PAR RESSORT DE TORSION
Abstract:
(EN) The invention relates to a torsion spring driven injection device for delivering set doses of a liquid drug wherein a torsion spring is strained by rotation of a rotatable dose setting structure and released by proximal movement of a piston rod driver. The dose setting structure is coupled to a drive element which is rotated during dose setting and which drive element is released during dosing to thereby rotate the piston rod driver. The piston rod driver is further coupled to the piston rod to generate a rotation and thus forward movement of the piston rod. The drive element and the piston rod driver are coupled to each other by a toothed engagement which is functional both during dose setting and during dose expelling.
(FR) L'invention concerne un dispositif d'injection entraîné par ressort de torsion pour administrer des doses définies d'un médicament liquide, un ressort de torsion étant sollicité par la rotation d'une structure de réglage de dose rotative et libéré par le mouvement proximal d'un dispositif d'entraînement de tige de piston. La structure de réglage de dose est couplée à un élément d'entraînement qui est mis en rotation pendant le réglage de dose et lequel élément d'entraînement est libéré pendant le dosage pour ainsi faire tourner le dispositif d'entraînement de tige de piston. Le dispositif d'entraînement de tige de piston est en outre couplé à la tige de piston pour générer une rotation et, par conséquent, un mouvement vers l'avant de la tige de piston. L'élément d'entraînement et le dispositif d'entraînement de tige de piston sont accouplés l'un à l'autre par une mise en prise dentée qui est fonctionnelle à la fois pendant le réglage de dose et pendant l'expulsion de dose.
