Abstract

The present invention relates to a supplementary device a supplementary device for a manually operable injection device. The supplementary device has a body defining a passage through which an injection device is slidable, and a securing unit to secure the body to the injection device in the specific position when the injection device is received through the passage.

First claim

The invention claimed is:

1. A supplementary device for a manually operable injection device, the supplementary device comprising
a body defining a passage through which an injection device is longitudinally slidable, the body including a front end having a front face and a rear end, wherein the rear end is configured to be positioned adjacent to a rear end of the injection device; and
a securing unit configured to axially and rotationally secure the body to the injection device in a specific position when the injection device is received through the passage, wherein the securing unit extends from the front face of the body,
wherein the securing unit comprises a collar which is longitudinally movable, relative to the body, between a secured position and a released position,
wherein the securing unit is configured to (i) secure the body to the injection device in the secured position and (ii) release the body from the injection device in the released position.

2. A supplementary device according to claim 1 , wherein the passage is an elongate bore formed in the body.

3. A supplementary device according to claim 1 , wherein the securing unit comprises at least two clamping surfaces, the securing unit being configured to receive the injection device between the at least two clamping surfaces when the injection device is received through the collar and to bias at least one of the at least two clamping surfaces towards another of the at least two clamping surfaces to clamp the injection device between the at least two clamping surfaces.

4. A supplementary device according to claim 1 , wherein the securing unit comprises at least two securing members which are spaced apart to receive the injection device there between, each securing member defining a clamping surface.

5. A supplementary device according to claim 4 , further comprising a biasing element configured to bias at least one of the at least two securing members towards the another securing member of the at least two securing members.

6. A supplementary device according to claim 5 , wherein the biasing element is the collar extending over the at least two securing members, the collar having a biasing section configured to act on at least one of the at least two securing members to releasably bias at least one of the clamping surfaces towards another clamping surface of the at least two clamping surfaces.

7. A supplementary device according to claim 6 , wherein the biasing section is tapered.

8. A supplementary device according to claim 6 , wherein the biasing section of the collar is threadingly engaged with the at least two securing members.

9. A supplementary device according to claim 1 , wherein the securing unit comprises an engaging element configured to engage with a cap retaining protrusion on the injection device when the body is disposed in a specific position relative to an outer surface of the injection device.

10. A supplementary device according to claim 1 , wherein the securing unit comprises an actuating member pivotably mounted in the body having at least one 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 outer surface of the injection device and the actuating member is pivoted towards the body.

11. A supplementary device according to claim 1 , further comprising a locating unit configured to locate the body in a specific position relative to an outer surface of the injection device.

12. A supplementary device according to claim 11 , further comprising an auxiliary cap retaining element configured to releasably retain a cap received over an end of the injection device when the supplementary device is secured to the injection device.

13. A supplementary device according to claim 1 , wherein the locating unit comprises a locating step configured to mate with a shoulder formed on the outer surface of the injection device and/or a guide slot configured to mate with a cap retaining protrusion on the injection device.

14. 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 the specific position relative to an outer surface of the injection device.

15. A kit comprising an injection device and a supplementary device according to claim 1 .

16. The supplementary device according to claim 1 , wherein the securing unit is configured to move axially between the secured position and the released position responsive to rotation of the securing unit relative to the body.

17. The supplementary device according to claim 1 , wherein the passage is configured to slidably receive the injection device through the passage in a direction from the front end to the rear end, and the securing unit is at the front end.

18. A supplementary device for a manually operable injection device, the supplementary device comprising:
a body defining a passage through which an injection device is slidable, the body including a front end having a front face and a rear end, wherein the rear end is configured to be positioned adjacent to a rear end of the injection device;
a securing unit configured to secure the body to the injection device in a predetermined rotational and axial position when the injection device is received through the passage, wherein the securing unit extends from the front face of the body,
wherein the securing unit comprises at least two securing members which are spaced apart to receive the injection device therebetween, each securing member defining a clamping surface,
wherein the securing unit comprises a biasing element configured to bias at least one of the at least two securing members towards the another securing member of the at least two securing members;
wherein the biasing element is a collar extending over the at least two securing members, the collar having a biasing section configured to act on at least one of the at least two securing members to releasably bias at least one of the clamping surfaces towards another clamping surface of the at least two clamping surfaces, and
wherein the biasing section of the collar is tapered and is threadingly engaged with the at least two securing members, such that rotation of the collar urges the collar in a longitudinal direction towards the body and urges at least one of the clamping surfaces towards another clamping surface of the at least two clamping surfaces.

19. The supplementary device of claim 18 , comprising a locating channel in an inner surface of the passage, the locating channel being shaped to provide a stop that limits axial insertion and rotation of the injection device relative to the body when the body is at a predetermined rotational and axial position relative to the injection device, wherein the locating channel includes a tapered surface configured to engage with a correspondingly shaped locating rib on the injection device to provide the stop.

20. A supplementary device for a manually operable injection device, the supplementary device comprising:
a body defining a passage through which an injection device is slidable, the body including a front end having a front face and a rear end, wherein the rear end is configured to be positioned adjacent to a rear end of the injection device, wherein the passage extends from a front end to a rear end of the supplementary device, such that when the injectio
