Abstract

The invention refers to a needle cap remover ( 7 ) for a needle cap ( 5.1 ) of a drug delivery device ( 2 ). The needle cap remover ( 7 ) comprises a body ( 8 ) having a material which differs from the material of the needle cap ( 5.1 ) or of a rigid needle shield ( 5 ) encasing the needle cap ( 5.1 ) in at least one parameter, wherein a body portion ( 8.1 ), which covers the needle cap ( 5.1 ) or the rigid needle shield ( 5 ) encasing the needle cap ( 5.1 ), is adapted to capture the needle cap ( 5.1 ) or the rigid needle shield ( 5 ) encasing the needle cap ( 5.1 ) by a positive and/or non-positive connections before or during removing of the needle cap ( 5.1 ) and is adapted to shrunk when a pulling force is applied.

First claim

1 . A needle cap remover for a needle cap of a drug delivery device, comprising:
a body having a material which differs from a material of the needle cap or a rigid needle shield encasing the needle cap in at least one parameter, wherein a portion of the body, which covers the needle cap or the rigid needle shield encasing the needle cap, is adapted to capture the needle cap or the rigid needle shield encasing the needle cap before or during removing of the needle cap.

2 . The needle cap remover according to claim 1 , wherein the body portion is formed as a shrinking hose adapted to be arranged onto the needle cap or onto the rigid needle shield encasing the needle cap and heat shrunk onto the needle cap or onto the rigid needle shield encasing the needle cap.

3 . The needle cap remover according to claim 2 , wherein the shrinking hose is formed as a sleeve of high impact resistance.

4 . The needle cap remover according to claim 2 , wherein a closed end of the body is formed as a dome from which a sleeve wall extends.

5 . The needle cap remover according to claim 1 , wherein the portion of the body is formed as a fabric tube that is adapted to be arranged onto the needle cap or onto the rigid needle shield encasing the needle cap and mechanically shrunk onto the needle cap or onto the rigid needle shield encasing the needle cap.

6 . The needle cap remover according to claim 5 , wherein the fabric tube is formed as an open-ended, tubular sleeve made of one or more of the following: fabric, textile, rubber and silicon.

7 . The needle cap remover according to claim 5 , wherein the fabric tube comprises an inner element comprising filling materials and/or inner threads.

8 . The needle cap remover according to claim 7 , wherein a gripping element is attached to a closed end of the body.

9 . The needle cap remover according to claim 1 , wherein the portion of the body is formed as a hollow sheet metal part adapted to be arranged onto the needle cap or onto the rigid needle shield encasing the needle cap and having protrusions directed inwards to engage the needle cap or the rigid needle shield encasing the needle cap.

10 . The needle cap remover according to claim 9 , wherein the sheet metal part comprises a plurality of inwardly directed protrusions which dig into the outer surface of the needle cap or of the rigid needle shield encasing the needle cap during removing of the needle cap.

11 . A drug delivery device comprising:
a housing; and a needle cap remover comprising:
a body having a material which differs from the material of the needle cap or a rigid needle shield encasing the needle cap in at least one parameter,
wherein a portion of the body, which covers the needle cap or the rigid needle shield encasing the needle cap, is adapted to capture the needle cap or the rigid needle shield encasing the needle cap before or during removing of the needle cap.

12 . The drug delivery device of claim 11 , further comprising a pharmaceutically active compound disposed in the housing.

13 . The needle cap remover according to claim 2 , wherein the shrinking hose is formed as a sleeve of thermoplastic-material.

14 . A method of removing a needle cap from a drug delivery device, the method comprising:
grasping a needle cap remover at a gripping element arranged at a closed end of the needle cap remover; pulling the needle cap remover distally from the drug delivery device, thereby causing a fabric tube of the needle cap remover to contract and join to a rigid needle cap to remove the needle cap with the needle cap remover.
