Abstract
Medication delivery devices are provided having a dose delivery sensing capability. A sensed element is attached to a dose setting member of the device. The sensed element includes surface features radially-spaced from one another. A rotational sensor is attached to an actuator of the device. The rotational sensor includes a movable element that is contactable against the surface features. The rotational sensor is configured to generate a signal in response to the movement of the movable element over the surface features during their rotation. A controller is operatively coupled to the rotational sensor, and in response to receiving the generated signal, the controller is configured to determine a number of the surface features passing the movable element of the rotational sensor during dose delivery. The number can be associated with an amount of dose delivered. Sensing can be provided in a module or integrated in device.
