Abstract

A needle shield remover is presented having a generally tubular body with a longitudinal extension and a grip element composed of a braided sleeve arranged to the tubular body, where the braided sleeve has an opening of such a diameter that a needle shield may be introduced, where the diameter narrows such that a friction fit is created between the braided sleeve and the needle shield when said needle shield is pulled for removing the needle shield.

First claim

The invention claimed is:

1. A needle shield remover, comprising:
a generally tubular body; and
a protective cap having an outside surface including a grip part, wherein an inside surface of the protective cap is connected to a proximal end of the generally tubular body,
wherein the generally tubular body comprises a first portion at a distal end of the generally tubular body and a second portion at the proximal end of the generally tubular body, wherein the first portion comprises a braided sleeve having an opening at a distal end of the generally tubular body with a first diameter such that a needle shield which is friction fit around an injection needle may be inserted into the opening, wherein the braided sleeve has a second diameter proximal to the distal end of the generally tubular body of such a size that a friction fit is created between the braided sleeve and the needle shield when said protective cap is pulled in a proximal longitudinal direction to thereby remove the needle shield from a medicament container, wherein the second portion of the generally tubular body comprises a ring, and wherein the ring comprises a material that is more rigid than a material of the braided sleeve.

2. The needle shield remover according to claim 1 , wherein the braided sleeve has length that extends in a longitudinal direction such that the braided sleeve covers generally the length of the needle shield when the needle shield is positioned inside of the braided sleeve.

3. The needle shield remover according to claim 1 , wherein the braided sleeve is contractable when pulled axially in a longitudinal direction.

4. The needle shield remover according to claim 1 , wherein the second diameter reduces in size when the braided sleeve is pulled axially in a longitudinal direction.

5. The needle shield remover according to claim 1 , wherein the braided sleeve is made of a plastic material.

6. The needle shield remover according to claim 1 , wherein the braided sleeve is made of a metallic material.

7. The needle shield remover according to claim 1 , wherein the generally tubular body further comprises an attachment element that connects to the protective cap.

8. The needle shield remover according to claim 7 , wherein the attachment element comprises a flange.

9. The needle shield remover according to claim 1 , wherein the generally tubular body is formed as an integral part of the protective cap.

10. The needle shield remover according to claim 1 , wherein the ring is formed as an integral part of the generally tubular body.

11. The needle shield remover according to claim 1 , wherein the grip part is configured so that a user can grip the protective cap to pull off the needle shield using the braided sleeve.

12. The needle shield remover according to claim 1 , wherein the generally tubular body comprises a non-braided portion that is connected to the inside surface of the protective cap.
