Logging device adapted to combine doses
First Claim
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 a 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;
one or more sensors adapted to capture, when the logging device is attached to the drug delivery device, a property value related to the dose amount of drug expelled from the reservoir by the expelling structure during an expelling event,a processor adapted to determine dose amounts based on captured property values, anda storage device adapted to store a plurality of dose amounts to create the log,wherein the logging device is configured to;
upon detecting the expelling event, said expelling event taking place a given amount of time after a previous detected expelling event, or after a given detected action, initiate tracking for a predefined time period; and
upon conclusion of the predefined time period, update or prompt the user to update the log with a combined entry corresponding to the combination of the stored dose amounts logged within the predefined time period.

Abstract
A drug delivery system comprises means to create a log of expelled dose amounts of drug. Stored dose amounts determined within a given time period are combined to a single combined dose amount. The given time period is initiated by a detected expelling event taking place (i) a given amount of time after a previous detected expelling event, or (ii) after a given detected action. By this arrangement it is possible to create a log corresponding to what a user considers to be a single dose, i.e. combining “split doses” to create a single log entry for a per se split dose.
