Abstract

A supplemental device for attachment to an injection device comprises an aligning arrangement for ensuring a predetermined positional relationship between the supplemental device and the injection device; and a securing arrangement for securing the supplemental device to the injection device.

First claim

The invention claimed is:

1. A supplemental device for attachment to an injection device, the supplemental device comprising:
an aligning arrangement for ensuring a predetermined positional relationship between the supplemental device and the injection device;
a securing arrangement for securing the supplemental device to the injection device, wherein the aligning arrangement comprises a locating channel in a main body of the supplemental device, the locating channel being configured to mate with a locating rib on the injection device, and wherein the locating channel has a variable depth and a variable thickness along a length of the locating channel; and
an optical reading arrangement directed at and at least partially covering a display of the injection device when the predetermined positional relationship between the supplemental device and the injection device is present.

2. A supplemental device as claimed in claim 1 , wherein the aligning arrangement and the securing arrangement are separate arrangements.

3. A supplemental device as claimed in claim 1 , wherein the locating channel is located at one end of the main body of the supplemental device.

4. A supplemental device as claimed in claim 1 , wherein the aligning arrangement comprises first and second protuberances located on first and second support members respectively, the supplemental device being configured such that the protuberances engage in indents on the injection device when the predetermined positional relationship is present.

5. A supplemental device as claimed in claim 4 , wherein the supplemental device has a main body defining an injection device receiving channel, wherein the protuberances are located on either side of the injection device receiving channel, and wherein the support members are biased towards each other.

6. A supplemental device as claimed in claim 5 , wherein the protuberances have sloping sides, and wherein a gradient of a side of each protuberance that is closest to a bottom of the injection device receiving channel is greater than a gradient of a side of the protuberance that is furthest from the bottom of the injection device receiving channel.

7. A supplemental device as claimed in claim 5 , wherein the securing arrangement comprises a closure coupled to the main body of the supplemental device at one hinge, wherein the closure is configured to rotate at the one hinge about a longitudinal axis of the supplemental device to enclose the injection device receiving channel.

8. A system comprising a supplemental device and an injection device, wherein the supplemental device comprises:
an aligning arrangement for ensuring a predetermined positional relationship between the supplemental device and the injection device, wherein the aligning arrangement comprises a locating channel in a main body of the supplemental device, the locating channel being configured to mate with a locating rib on the injection device, and wherein the locating channel has a variable depth and a variable width along a length of the locating channel that corresponds to a variable height and a variable thickness of the locating rib;
a securing arrangement for securing the supplemental device to the injection device; and
an optical reading arrangement directed at and at least partially covering a display of the injection device when the predetermined positional relationship between the supplemental device and the injection device is present.

9. A system as claimed in claim 8 , wherein the supplemental device is located so as not to inhibit user access to a dosage knob or an injection button of the injection device when the predetermined positional relationship between the supplemental device and the injection device is present.

10. A system as claimed in claim 8 , wherein the supplemental device is located so as not to fully cover a medicament information label provided on the injection device when the predetermined positional relationship between the supplemental device and the injection device is present.

11. A system as claimed in claim 8 , wherein the injection device comprises at least one protrusion interacting with the alignment arrangement of the supplemental device.

12. A system as claimed in claim 11 , wherein the at least one protrusion comprises the locating rib.

13. A system as claimed in claim 8 , wherein the injection device comprises at least one indent interacting with the alignment arrangement of the supplemental device.

14. A system as claimed in claim 8 , wherein the injection device comprises the locating rib and two indents which are in engagement with the locating channel and protuberances, respectively, of the supplemental device.

15. A supplemental device for attachment to an injection device, the supplemental device comprising:
an aligning arrangement for ensuring a predetermined positional relationship between the supplemental device and the injection device, wherein the aligning arrangement comprises first and second protuberances located on first and second support members respectively, the supplemental device being configured such that the protuberances engage in indents on the injection device when the predetermined positional relationship is present;
a securing arrangement for securing the supplemental device to the injection device; and
an optical reading arrangement directed at and at least partially covering a display of the injection device when the predetermined positional relationship between the supplemental device and the injection device is present,
wherein the supplemental device has a main body defining an injection device receiving channel, wherein the protuberances are located on either side of the injection device receiving channel, and wherein the support members are biased towards each other.

16. A supplemental device as claimed in claim 15 , wherein the aligning arrangement and the securing arrangement are separate arrangements.

17. A supplemental device as claimed in claim 15 , wherein the aligning arrangement comprises a locating channel in the main body of the supplemental device, the locating channel being configured to mate with a locating rib on the injection device.

18. A supplemental device as claimed in claim 17 , wherein the locating channel is located at one end of the main body of the supplemental device.

19. A supplemental device as claimed in claim 15 , wherein the protuberances have sloping sides, and wherein a gradient of a side of each protuberance that is closest to a bottom of the injection device receiving channel is greater than a gradient of a side of the protuberance that is furthest from the bottom of the injection device receiving channel.

20. A supplemental device as claimed in claim 15 , wherein the securing arrangement comprises a closure coupled to the main body of the supplemental device at one hinge, wherein the closure is configured to rotate at the one hinge about a longitudinal axis of the supplemental device to enclose the injection device receiving channel.
