Abstract
Official abstract text for this publication.
The present disclosure relates to a resettable drive mechanism for use in a drug delivery device. The drug delivery device is having a distal direction and a proximal direction. The drive mechanism comprises a drive rack engaged with a drive gear, a piston rack engaged with a piston gear and coupling means for coupling the drive gear with the piston gear. In a first state of the drive mechanism, the drive gear and the piston gear are coupled and the piston rack moves in distal direction when the drive rack is moved in distal direction. In a second state of the drive mechanism, the drive gear and the piston gear are decoupled and the piston rack is moveable in proximal direction for resetting the drive mechanism.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resettable drive mechanism for use in a drug delivery device having a distal end and a proximal end, wherein the drive mechanism comprises a drive rack engaged with a drive gear: a piston rack engaged with a piston gear and having a first part and a second part; a coupling coupling the drive gear with the piston gear; and a non-return member operably engaged with the piston gear to prevent rotation of the piston gear in one direction while the…
