摘要:
A medication delivery device including a drive mechanism, a retraction mechanism and a sensing system. A medication container is movable relative to the medication delivery device between storage and delivery positions. The drive mechanism drives a plunger in a translational movement to move the medication container from the storage position to the delivery position and to dispense medication from the medication container in a dispensing event. The retraction mechanism includes a rotary member that rotates during a retraction movement of the retracting mechanism. The sensing system includes a first sensor to detect operational status and a second sensor to sense rotational movement of the rotary member. A controller is configured to detect initiation of a dispensing event based on signals generated by the first sensor and detect completion of the dispensing event and/or completion of the retraction movement based on signals generated by the second sensor.
