The invention concerns an injection device for apportioning set doses of a drug from a reservoir to a subject. The injection device comprises a dose setting member (20, 70) which is screwed out from the housing (30) to set a dose and pushed axially back to the housing (30) in order to expel the set dose. A scale drum (80) is axially and inrotatable coupled to the dose setting member (20, 70) such that the scale drum (80) is rotated up a thread (34) when the dose setting member (20, 70) is rotated to set a dose. When the dose setting member (20, 70) is pushed axially back to its initial position to inject the set dose, the scale drum (80) is released from its inrotatable connection in order to allow the scale drum (80) to rotate down the thread (34) and back to its zero position.
L'invention concerne un dispositif d'injection qui permet d'administrer à un sujet des doses fixées d'un médicament depuis un réservoir. Le dispositif de l'invention comprend un organe de réglage de dose (20, 70) que l'on dévisse d'un logement (30) pour régler une dose et que l'on repousse axialement vers le logement (30) afin d'expulser la dose fixée. Un tambour gradué (80) est couplé axialement de manière non rotative à l'organe de réglage de dose (20, 70) de manière que le tambour gradué (80) tourne le long d'un filetage (34) lorsque l'on fait tourner l'organe de réglage de dose (20, 70) pour régler une dose. En repoussant l'organe de réglage de dose (20, 70) axialement dans sa position initiale pour injecter la dose fixée, on libère le tambour gradué (80) de son raccordement non rotatif, lui permettant par conséquent de tourner en sens opposé le long du filetage (34) pour revenir à sa position intiale.
