Abstract
A supplementary device for attachment to a drug delivery device is provided. The device includes an attachment mechanism for coupling the supplementary device to the drug delivery device, an imaging arrangement for providing image data representing a captured image of one or more numbers present on a number sleeve of the drug delivery device and a processor arrangement. The processor arrangement is configured to receive the image data; perform optical character recognition on the image data to determine a quantity of a currently set dose of medicament; cause display of the quantity of the currently set dose; process the image data to identify one or more characteristics of the number sleeve; determine from the identified characteristics whether the currently set dose is a permitted dose; and if the currently set dose is not a permitted dose, cause an indication that the currently set dose is not a permitted dose.
