Abstract
A medication delivery device comprising a housing, a medication receptacle, a piston rod which is moveable distally, and a drive device for rotating the piston rod in a first rotational direction. The piston rod comprises two threaded sections, a first threaded section for threaded engagement with a reset element and a second threaded section for threaded engagement with the drive device. In an operational state, the reset element is prevented from rotating and the piston rod prevented from moving proximally. In a resetting state, the reset element is allowed to rotate, such that the delivery device is resettable by rotating the piston rod and the reset element in a second rotational direction and moving the piston rod proximally.
