DRUG DELIVERY ASSEMBLY WITH INFORMATION CAPTURE

Abstract:

A drug delivery assembly comprising an indicator adapted to move during expelling of a dose amount of drug, the amount of movement being indicative of the size of the expelled dose amount, and electronic tracking sensor circuitry adapted to with pre-determined intervals to change the operative state from a sleep state to a low-power detection state and back to the sleep state. When in the detection state, the electronic sensor circuitry is adapted to detect motion of an activation component, and if motion of the activation component is detected, then change the operative state from the low-power detection state to a high-power measuring state in which the amount of motion of the indicator relative to the tracking means can be determined.
