1. A logging device adapted to be releasably attached to a drug delivery device, the drug delivery device comprising a drug reservoir or structure for receiving a drug reservoir, and drug expelling structure comprising dose setting structure allowing a user to set a dose amount of drug to be expelled, the logging device comprising:
electronic circuitry adapted to create a log of expelled dose amounts of drug, comprising:
sensor structure adapted to capture, when the logging device is attached to a drug delivery device, a property value related to the dose amount of drug expelled from a reservoir by the expelling structure during an expelling event,processor structure adapted to determine dose amounts based on captured property values, andstorage structure adapted to store a plurality of dose amounts to create the log,wherein:
stored dose amounts determined within a given time period are combined or can be combined to a single combined dose amount, and the given time period is initiated by a detected expelling event taking place:
a given amount of time after a previous detected expelling event, orafter a given detected action. |
