Patent attributes
A medication delivery device including a device body and a dose setting component coupled to the device body. Component is rotatable relative to the device body in relation to an amount of a set or delivered dose. An annular sensed element, such as a metal or magnetic ring, is positioned on a proximal surface of the dose setting component. A carrier secures the sensed element to the dose setting component. The carrier includes a proximal overlapping support that is contactable against the sensed element opposite the proximal surface of the dose setting component. The carrier is configured to axially and rotationally fix the sensed element to the dose setting component. The device may include a dose detection system operable with the sensed element.
