Abstract
A supplementary device configured to be releasably attached to an injection device includes at least one wireless communication unit and at least one sensor, wherein the supplementary device is configured to activate the at least one sensor in response to receipt via the at least one wireless communication unit of a wireless communication from an external device, following activation, to use the at least one sensor to detect the start of an injection by the injection device, and to communicate, via the at least one wireless communication unit, the start of the injection to the external device.
Claims20
A supplementary device configured to be releasably attached to an injection device, the supplementary device comprising:
- at least one wireless communication unit;
- at least a pair of elongate attachment means for releasably attaching the supplementary device to the injection device;
- and
- an optical sensor arrangement comprising an extension that extends along a first axis substantially parallel to a longitudinal axis of the injection device and through a distal end of the injection device into a cavity of the injection device when the supplementary device is attached to the injection device such that the optical sensor arrangement is usable to detect a start of an injection by detecting a movement of a part within the injection device, wherein the extension is configured to extend a greater distance along the first axis within the cavity than any distance perpendicular to the first axis, and
- wherein the supplementary device is configured to:
- use the optical sensor arrangement to detect the start of the injection by the injection device, and
- communicate, via the at least one wireless communication unit, the start of the injection to an external device.
