Patent number: 11298464Abstract: An assembly for a drug delivery device includes a housing, a rotation member, a drive member and at least one correction member. In a delivery mode, the drive member and the rotation member are coupled such that the drive member follows rotational movement of the rotation member in a first rotational direction. In a correction mode, the rotation member and the drive member are decoupled such that the rotation member is rotatable in the first rotational direction with respect to the drive member. For switching from the delivery mode into the correction mode, the correction member is moveable with respect to the housing, wherein the assembly is configured such that movement of the correction member with respect to the housing is converted into a relative movement between the drive member and the rotation member for decoupling the drive member and the rotation member.Type: GrantFiled: April 20, 2018Date of Patent: April 12, 2022Assignee: Sanofi-Aventis Deutschland GMBHInventors: Philippe Nzike, Steffen Raab, Uwe Dasbach, Uwe Boeser, Ulrich Bruggemann

Publication number: 20180236175Abstract: An assembly for a drug delivery device (1) comprises a housing (5), a rotation member (15), a drive member (16) and at least one correction member (7). The rotation member (15) is adapted to be rotated with respect to the housing (5) in a first rotational direction for delivering a dose of a drug (11). The drive member (16) is coupleable to the rotation member (15) for delivering the dose. In a delivery mode, the drive member (16) and the rotation member (15) are coupled such that the drive member (16) follows rotational movement of the rotation member (15) in the first rotational direction due to mechanical interaction of the rotation member (15) and the drive member (16). In a correction mode, the rotation member (15) and the drive member (16) are decoupled such that the rotation member (15) is rotatable in the first rotational direction with respect to the drive member (16).Type: ApplicationFiled: April 20, 2018Publication date: August 23, 2018Inventors: Philippe Bertrand Nzike, Steffen Raab, Uwe Dasbach, Uwe Boeser, Ulrich Bruggemann

Patent number: 8968258Abstract: A resettable drive mechanism for a medication delivery device comprising a housing and a drive member rotatable in a second direction for delivering a dose. A piston rod driven distally when a drive member rotates in the second direction. A stop member prevents rotation of the drive member in a first direction opposite the second direction, when the stop member engages the drive member. A clutch member is movable between a delivery and reset position. When the clutch member is in the delivery position, the stop member and the drive member engage and the drive member is prevented from rotating in the first direction. When the clutch member is in the reset position, the drive member and the stop member disengage. The drive member is rotatable in the first direction.Type: GrantFiled: December 9, 2009Date of Patent: March 3, 2015Assignee: Sanofi-Aventis Deutschland GmbHInventors: Philippe Nzike, Steffen Raab, Ulrich Brüggemann, Uwe Dasbach, Uwe Boeser
