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.

First claim

What is claimed is:

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.

11. A medicament delivery device comprising:
a housing having a proximal end comprising an end surface; and a cover assembly, comprising: a manually operable member having a proximal end wall and a distal end comprising a cam interface projecting distally, where the manually operable member has an outer surface having a grip area comprising protrusions and valleys, where the cam interface terminates at a highest point; an RNS remover comprising a tubular shaped member having a proximal end and a distal end; a rigid needle shield partially covered by the tubular shaped member, where the tubular shaped member has two grip members located at the distal end configured to engage the rigid needle shield when the cover assembly is moved axially in a proximal direction, where the rigid needle shield has an internally arranged resilient cap arranged to house and protect an injection needle; and a spinning attachment axially fixed to the proximal end of the RNS remover and attached to the proximal end wall of the manually operable member such that the manually operable member can be freely turned in relation to the RNS remover but is locked in an axial direction such that there is no relative axial movement between the RNS remover and the manually operable member, where the spinning attachment further comprises a tubular section,
wherein rotation of the manually operable member relative to the housing causes the cam interface to engage and slide relative to the proximal end surface of the housing causing the manually operable member, the RNS remover and the rigid needle shield to each move axially in the proximal direction until the end surface of the proximal end of the housing reaches the highest point.
