Abstract

The invention relates to a boot remover ( 10 ) for removing a protective needle boot ( 11 ) from a drug delivery device ( 1 ), wherein the boot remover ( 10 ) is substantially sleeve shaped with an internal diameter and a length adapted to receive and substantially cover a needle shield ( 4 ), wherein the boot remover ( 10 ) is arranged to engage the protective needle boot ( 11 ) when attacked to the drug delivery device ( 1 ). Furthermore, the invention relates to a drug delivery device ( 1 ) comprising a boot remover ( 10 ).

First claim

The invention claimed is:

1. A drug delivery device for dispensing a dose of a drug, comprising:
a support body having a first end defining a first opening and a second end defining a second opening,
a syringe barrel sealed by a stopper slidably disposed therein along an axial direction and adapted to have an integrated needle or to be coupled with a needle assembly comprising a needle, wherein the syringe barrel is positioned within the support body,
a protective needle boot arrangeable over the needle on the syringe barrel,
a needle shield adapted to be coupled to one of the first end and the second end of the support body and slidably disposed relative to the support body for covering or exposing the needle,
an outer body coupled to the other of the first end and the second end of the support body and slidably disposed relative to the support body; and
a boot remover for removing the protective needle boot from the syringe barrel, the boot remover comprising a clamping collar arranged to engage a coupling protrusion of the protective needle boot, such that the protective needle boot is axially coupled to the boot remover, wherein the boot remover is substantially sleeve shaped with an internal diameter and a length adapted to receive and substantially cover the needle shield, wherein the boot remover is arranged to engage the protective needle boot when attached to the drug delivery device.

2. The drug delivery device according to claim 1 , wherein the clamping collar is arranged to allow rotation of the protective needle boot relative to the boot remover.

3. The drug delivery device according to claim 2 , wherein the coupling protrusion of the protective needle boot is mushroom-shaped for engaging in a bore within the clamping collar.

4. The drug delivery device according to claim 1 , wherein the boot remover is arranged to engage the protective needle boot by friction.

5. The drug delivery device according to claim 1 , wherein the boot remover is arranged as a handle integrally shaped with the protective needle boot.

6. The drug delivery device according to claim 1 , comprising a direction indicator for indicating a direction for removing the protective needle boot.

7. The drug delivery device according to claim 1 , comprising at least one grip feature.

8. The drug delivery device according to claim 1 , wherein the clamping collar forms a recess with the coupling protrusion located in a center of the clamping collar.

9. The drug delivery device according to claim 1 , wherein the coupling protrusion is arranged at a distal end of the protective needle boot.

10. The drug delivery device according to claim 1 , wherein a plunger rod is coupled to the stopper, and wherein a proximal portion of the plunger rod is adapted to be coupled to the outer body.

11. The drug delivery device according to claim 1 , wherein a detent mechanism is arranged to constrain movement of the outer body relative to the support body.

12. The drug delivery device according to claim 1 , wherein a sleeve is arrangeable over the support body.

13. The drug delivery device according to claim 12 , wherein the sleeve is transparent.

14. The drug delivery device according to claim 1 , wherein the syringe barrel contains a pharmaceutically active compound.

15. The drug delivery device according to claim 1 , wherein the boot remover is arranged to engage the protective needle boot by friction and by at least one barb engageable in a recess or behind a shoulder on the protective needle boot.

16. The drug delivery device according to claim 1 , wherein the boot remover is arranged to engage the protective needle boot by at least one barb engageable in a recess or behind a shoulder on the protective needle boot.

17. The drug delivery device according to claim 1 , wherein the needle shield is configured to move from an extended position, in which the needle shield covers the needle, to an retracted position, in which the needle shield exposes the needle, and wherein the needle shield is directly coupled to the support body in the retracted and extended positions.

18. The drug delivery device according to claim 1 , wherein the needle shield is slidably attached to the support body.
