Abstract

A needle cover assembly includes a manually operable member; a rigid needle shield (RNS) provided with an internally arranged resilient cap, in turn arranged to house and protect an injection needle; and a RNS remover assembly including a tubular shaped member surrounding the RNS, in which the tubular shaped member is arranged with at least one grip member capable of gripping the RNS in order to remove the RNS. The RNS remover assembly further includes a spinning attachment member having a distal end fixedly attached to the tubular shaped member and a proximal end rotatably attached to the manually operable member such that the manually operable member can be freely turned in relation to the RNS remover assembly but is locked in an axial direction.

Claims

1. A needle cover assembly, comprising:

a manually operable member having an annular distal end surface;

a housing of a medicament delivery device having a corresponding proximally directed annular surface in contact with the distal end surface, the housing can be releasably attached to the manually operable member;

wherein the surfaces form an interface having a wave or cam shape;

a rigid needle shield (RNS) having an internally arranged resilient cap, in turn arranged to house and protect an injection needle; and

a RNS remover assembly, comprising;

a tubular shaped member surrounding the RNS, wherein the tubular shaped member is arranged with at least one grip member capable of gripping the RNS in order to remove the RNS, and

a spinning attachment member having a distal end fixedly attached to the tubular shaped member and a proximal end rotatably attached to the manually operable member such that when the manually operable member is turned in relation to the housing, the RNS remover assembly is moved in an axial direction without rotation.

2. The needle cover assembly of claim 1, wherein the at least one grip member comprises pointed tabs inclined in the proximal direction and configured to be pushed through openings on the RNS and into the resilient cap.

3. The needle cover assembly of claim 2, wherein the tubular shaped member is made of a metallic material.

4. The needle cover assembly of claim 2, wherein the manually operable member has manual grip areas on its outer circumference surface to enhance manual gripping of a cap cover.

5. The needle cover assembly of claim 4, wherein the manual grip areas have different geometrical shapes for providing tactile information.

6. The needle cover assembly of claim 1, wherein the tubular shaped member is made of a metallic material.

7. The needle cover assembly of claim 6, wherein the manually operable member has manual grip areas on its outer circumference surface to enhance manual gripping of a cap cover.

8. The needle cover assembly of claim 7, wherein the manual grip areas have different geometrical shapes for providing tactile information.

9. The needle cover assembly of claim 1, wherein the manually operable member has manual grip areas on its outer circumference surface to enhance manual gripping of a cap cover.

10. The needle cover assembly of claim 9, wherein the manual grip areas have different geometrical shapes for providing tactile information.
