Abstract
The invention relates to an apparatus (2, 3), comprising a mating unit (20-1, 20-2) for releasably attaching the apparatus (2) to a medical device (1) or for releasably receiving at least a part of the medical device (1). The apparatus (2, 3) further comprises one or more optical sensors (25, 26) and/or one or more acoustical sensors (27) for determining information related to a condition and/or use of the medical device (1). The invention further relates to a system comprising such an apparatus (2, 3) and such a medical device (1), to a method (500, 600, 700) and a computer program (61) for determining information related to a condition and/or use of such a medical device (1), and to a computer-readable medium (60) storing such a computer program (61).

43. A method of utilizing a supplementary device to determine information related to an injection device, the method comprising the step of
activating a supplementary device; - and further comprising at least one of the following steps
determining a type of medicament contained within the injection device; determining a currently selected dose; displaying the currently selected dose; at least partially monitoring timing of the application sequence, checking whether an ejection has taken place;
whereinthe step of determining whether an ejection has taken place further comprises the step of differentiating a prime shot from an injection. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51)
capturing a sub-image by an optical sensor; and processing the captured sub-image.
- and further comprising at least one of the following steps
-
49. The method of claim 48 wherein
the step of processing the captured sub-image comprises the steps of dividing the captured image by a previously captured background image; -
binning of the images to reduce a number of pixels; normalizing the images to reduce intensity variations in the illumination; sheering of the captured sub-image and the previously captured background image; and comparing the captured sub-image and the previously captured background image to a fixed threshold.

50. The method of claim 49 further comprising the step of
determining whether there is a change in the captured sub-image, wherein the step of determining whether there is a change in the captured sub-image comprises the step of comparing the currently captured sub-image to the previously captured sub image. -
51. The method of claim 50 wherein
if it is determined that there is a change in the captured sub-image, the method further comprising the steps of capturing a sub-image by an optical sensor; - and
processing the captured sub-image.

52. A method of creating a logbook of selected doses in a supplementary device, the method comprising the steps of
determining a selected dose; -
determining whether the selected dose comprises a dose equal to zero; if the selected dose does not equal zero, the method further comprises the steps of setting an initial dose value to a value of the determined selected dose; determining if the initial dose value was previously defined; if it is determined that the initial dose a supplementary device has been previously defined, the method includes the step of setting an end dose value to the determined selected dose; displaying a difference between the value of the initial dose and the value of the end dose, confirming the difference to be injected; and storing the difference as a corresponding entry in a logbook as being injected. - View Dependent Claims (53, 54, 55, 56, 57, 58, 59)
