Zusammenfassung: | The present invention refers to a drug delivery device (1) and to a method of operating same. The drug delivery device (1) may comprise a housing (10; 32), a dial grip (12) manually operable by a user for setting an individual dose to be delivered by the drug delivery device (1), a dose setting and drive mechanism, which is configured to perform a dose setting operation in response to the operation of the dial grip (12) and which is configured to perform a dose delivery operation for delivering the set dose, a clutch (20) comprising two clutch members (21, 22; 31, 33; 43, 44) for rotationally coupling and de-coupling the dial grip (12) to the housing (10; 32) and/or to the dose setting and drive mechanism, at least one processor, a sensor arrangement (29, 30) connected to the at least one processor and operable to generate measurement data indicative of the dose setting operation, and a power source (28) connected to the at least one processor. The drug delivery device (1) further comprises a clutch actuator (23, 24; 23; 39, 23, 42) operable by the at least one processor to trigger a switch of the state of the clutch (20). The at least one processor is configured to operate the clutch actuator (23, 24; 23; 39, 23, 42) if the measurement data generated by the sensor arrangement (29, 30) reaches a threshold. |
