Title (EN) ASSEMBLY FOR A MEDICATION DELIVERY DEVICE AND MEDICATION DELIVERY DEVICE COMPRISING SUCH AN ASSEMBLY
(FR) ENSEMBLE POUR UN DISPOSITIF D'ADMINISTRATION DE MÉDICAMENT ET DISPOSITIF D'ADMINISTRATION DE MÉDICAMENT COMPRENANT UN ENSEMBLE
Abstract:
(EN) The present disclosure relates to an assembly for a medication delivery device (1). The assembly comprises a body (2), a piston rod (3) and a setting nut (4). The piston rod (3) is adapted and arranged to be rotated with respect to the body (2) in a dose setting state of the assembly for setting a dose of a medication (12) and to be axially moved in a distal direction with respect to the body (2) in a dose delivering state of the assembly for delivering the set dose of the medication (12). The setting nut (4) is secured against rotational movement with respect to the body (2), but enabled for axial movement with respect to the body (2), and further helically coupled with the piston rod (3). The setting nut (4) is adapted and arranged to axially travel in the proximal direction with respect to the body (2) for setting a dose of a medication (12) due to a helical movement of the setting nut (4) with respect to the piston rod (3) when the piston rod (3) is rotated with respect to the body (2) in the dose setting state of the assembly. Moreover, the setting nut (4) is adapted and arranged to axially travel in the distal direction with respect to the body (2) for delivering the set dose of the medication (12) when the piston rod (3) is axially moved in the distal direction with respect to the body (2) in the dose delivering state of the assembly.
(FR) La présente invention concerne un ensemble pour un dispositif (1) d'administration de médicament. L'ensemble comprend un corps (2), une tige de piston (3) et un écrou de réglage (4). La tige de piston (3) est conçue et agencée pour être tournée par rapport au corps (2) dans un état de réglage de dose de l'ensemble, pour régler une dose d'un médicament (12), et pour être déplacée axialement dans une direction distale par rapport au corps (2) dans un état d'administration de dose de l'ensemble, pour administrer la dose réglée du médicament (12). L'écrou de réglage (4) est bloqué contre un mouvement de rotation par rapport au corps (2), mais est activé pour un mouvement axial par rapport au corps (2), et en outre couplé de façon hélicoïdale à la tige de piston (3). L'écrou de réglage (4) est conçu et agencé pour se déplacer axialement dans la direction proximale par rapport au corps (2) pour régler une dose d'un médicament (12) en raison d'un mouvement hélicoïdal de l'écrou de réglage (4) par rapport à la tige de piston (3) lorsque la tige de piston (3) est tournée par rapport au corps (2) dans l'état de réglage de dose de l'ensemble. De plus, l'écrou de réglage (4) est conçu et agencé pour se déplacer axialement dans la direction distale par rapport au corps (2) pour administrer la dose réglée du médicament (12) lorsque la tige de piston (3) est déplacée axialement dans la direction distale par rapport au corps (2) dans l'état d'administration de dose de l'ensemble.
