  "claims": [
    "1. A supplementary device for attachment to a manually operable injection device, the supplementary device comprising a body having an injection device receiving channel; and a mating unit configured to releasably mount the body to the injection device in a specific position relative to an outside surface of the injection device, wherein the mating unit comprises a collar extending from the body, wherein the collar is configured to receive the injection device so that the injection device extends through the collar, and wherein the collar comprises a closure which is rotatable towards the body about an axis of rotation that is transverse to a longitudinal axis of the injection device receiving channel to secure the body to the injection device.",
    "2. A supplementary device according to claim 1, wherein the mating unit further comprises an engaging unit configured to engage the supplementary device with the injection device.",
    "3. A supplementary device according to claim 2, wherein the engaging unit comprises a support member having an engaging element, the engaging element being configured to engage in an indent on the injection device when the body is disposed in a specific position relative to an outside surface of the injection device.",
    "4. A supplementary device according to claim 3, wherein the support member is a first support member and the engaging unit further comprises a second support member, engaging elements being disposed at the free end of each support member, and the free ends of the support members being biased towards each other.",
    "5. A supplementary device according to claim 4, wherein each support member is pivotally mounted in the body about a mid-section so that the free ends of the support members may be biased away from each other to disengage the engaging elements from the indents.",
    "6. A supplementary device according to claim 1, wherein the closure is configured to act on the support member to urge the engaging element into the indent when the closure is in its secured position so that the body is secured to the injection device.",
    "7. A supplementary device according to claim 6, wherein the mating unit further comprises a catch arrangement configured to releasably retain the closure in its secured position.",
    "8. A supplementary device according to claim 1, wherein the mating unit further comprises a locating recess in the body, the locating recess being configured to mate with a locating rib on the injection device.",
    "9. A supplementary device according to claim 1, further comprising an optical reading arrangement and wherein the optical reading arrangement is directed at a display of the injection device when the body is mounted to the injection device in a specific position relative to an outside surface of the injection device.",
    "10. A supplementary device according to claim 1, together with an injection device.",
    "11. A supplementary device as claimed in claim 3, wherein the support member is disposed behind a wing which is formed from a transparent material.",
    "12. A supplementary device for attachment to a manually operable injection device, the supplementary device comprising: a body having a front end and a rear end; and a mating unit configured to releasably mount the body to the injection device in a specific position relative to an outside surface of the injection device, wherein the mating unit comprises: a collar extending from the front end of the body at an acute angle to the longitudinal axis of the body and configured to receive the injection device so that the injection device extends through the collar; an engaging unit configured to engage the supplementary device with the injection device; and first and second locating surfaces spaced from each other to receive the injection device therebetween, wherein the first locating surface and the second locating surface are offset, wherein the collar comprises an opening, wherein the collar is configured to be pivoted about an axis extending perpendicular to the major axis of the opening between a first position in which the injection device is slidably receivable through the collar and a secured position in which the first and second locating surfaces are located against opposite outer surfaces of the injection device and positioned such that no part of the first locating surface is directly opposite the second locating surface when in the secured position, and wherein the engaging unit is configured to become engaged with the injection device as the collar is pivoted into the secured position.",
    "13. A supplementary device according to claim 12, wherein the second locating surface is disposed between the first locating surface and the engaging unit.",
    "14. A supplementary device according to claim 12 wherein the engaging unit further comprises a support member having an engaging element, the engaging element being configured to engage in an indent on the injection device when the collar is in the secured position.",
    "15. A supplementary device according to claim 14, wherein the support member is a first support member and the engaging unit further comprises a second support member, wherein the engaging elements are disposed at the free end of each support member, and wherein the free ends of the support members are biased towards each other.",
    "16. A supplementary device according to claim 14, wherein each support member is pivotally mounted in the body about a mid-section so that the free ends of the support members may be biased away from each other to disengage the engaging elements from the indents.",
    "17. A supplementary device according to claim 12, wherein the mating unit further comprises a locating recess in the body, the locating recess being configured to mate with a locating rib on the injection device.",
    "18. A supplementary device according to claim 12, further comprising an optical reading arrangement and wherein the optical reading arrangement is directed at a display of the injection device when the body is mounted to the injection device in a specific position relative to an outside surface of the injection device.",
    "19. A supplementary device according to claim 12, together with an injection device.",
    "20. A supplementary device as claimed in claim 14, wherein the support member is disposed behind a wing which is formed from a transparent material."

  "description_excerpt": "The present invention relates to an apparatus for supplementing a medical device configured to eject a medicament. In particular, the present invention relates to a supplementary device for a manually operable injection device.\n\nA variety of diseases exists that require regular treatment by injection of a medicament. Such injection can be performed by using injection devices, which are applied either by medical personnel or by patients themselves. As an example, type-1 and type-2 diabetes can be treated by patients themselves by injection of insulin doses, for example once or several times per day. For instance, a pre-filled disposable insulin pen can be used as an injection device. Alternatively, a re-usable pen may be used. A re-usable pen allows replacement of an empty medicament cartridge by a new one. Either pen may come with a set of one-way needles that are replaced before each use. The insulin dose to be injected can then for instance be manually selected at the insulin pen by turning a dosage knob and observing the actual dose from a dose window or display of the insulin pen. The dose is then injected by inserting the needle into a suited skin portion and pressing an injection button of the insulin pen.\n\nTo be able to monitor insulin injection, for instance to prevent false handling of the insulin pen or to keep track of the doses already applied, it is desirable to measure information related to a condition and/or use of the injection device, such as for instance information on the injected insulin type and dose. In this respect, WO 2009/024562 discloses a medical device with a value sensor.",
