A drug delivery device comprising:
- a housing;
- a moveable number sleeve disposed within the housing and having numbers printed thereon;
- and
- a transparent window occupying an aperture of the housing and covering the number sleeve such that the number sleeve is visible through the transparent window,
- wherein at least one region of the housing located adjacent the transparent window is transparent to visible light and is in optical communication with the transparent window.
A supplementary device for attachment to a drug delivery device, the supplementary device comprising:
- an imaging arrangement configured to capture an image of a moveable number sleeve of the drug delivery device, the number sleeve disposed beneath a transparent window;
- and
- at least one illumination source configured to illuminate the number sleeve indirectly by being positioned such that when the supplementary device is attached to the drug delivery device light from the one or more illumination sources is incident on a region of the housing located adjacent the transparent window, the region being in optical communication with the transparent window.
A system comprising a drug delivery device and a supplementary device, the drug delivery device comprising:
- a housing;
- a moveable number sleeve disposed within the housing and having numbers printed thereon;
- and
- a transparent window occupying an aperture of the housing and covering the number sleeve such that the number sleeve is visible through the transparent window, wherein at least one region of the housing located adjacent the transparent window is transparent to visible light and is in optical communication with the transparent window, and;
- the supplementary device comprising:
- an imaging arrangement configured to capture an image of a moveable number sleeve of a drug delivery device, the number sleeve disposed beneath a transparent window;
- and;
- one or more illumination sources configured to illuminate the number sleeve indirectly by being positioned such that when the supplementary device is attached to the drug delivery device, light from the one or more illumination sources is incident on a region of the housing located adjacent the transparent window, the region being in optical communication with the transparent window.
A method to measure information related to a drug delivery device comprising
- configuring a supplementary device, containing an imaging arrangement, to be attached to a housing of a drug delivery device, the housing of the drug delivery device comprising an optically transparent window directly covering a movable number sleeve displaying a value that corresponds with a user variable dosage,
- collecting optical data from preparation and use of the drug delivery device via the supplementary device, and
- processing and displaying the optical data via a display unit on the supplementary device.
