Abstract
A needle shield remover is presented having a generally tubular body with a longitudinal extension and a number of grip elements arranged at a distal area of the body, where the grip elements extend radially inwards from a circumference of the body. At least one longitudinally extending cut-out in the body and adjacent to the grip elements engage an outer surface of a needle shield when the needle shield remover is pushed onto the needle shield, where the at least one cut-out enables a generally radial outwardly bias of the grip elements during the pushing action to facilitate mounting of the needle shield remover on the needle shield.
Claims20
1-9. (canceled)
10:
- A needle shield remover for a medicament delivery device, the needle shield remover comprising:
- a generally tubular body having a longitudinal extension and a proximal end;
- a number of grip elements arranged at a distal area of the body, the grip elements extending radially inwards from a circumference of the body;
- and
- at least one longitudinally extending cut-out at said distal area of said body adjacent and between the grip elements,
- wherein the grip elements are adapted to engage an outer surface of a needle shield when the needle shield remover is pushed onto the needle shield,
- wherein at least one cut-out adjacent the grip elements enables a generally radial outwardly bias of the grip elements during the pushing action that facilitates mounting of the needle shield remover on the needle shield, and wherein the proximal end is arranged with attachment elements for engagement with a grip part of a protective cap of the medicament delivery device.
4 more elements
11:
- The needle shield remover according to claim 10, wherein said tubular body has an extension in the longitudinal direction in relation to a length of said needle shield such that said grip elements are placed after a distal end wall of the needle shield when mounted.
12:
- The needle shield remover according to claim 10, wherein the grip elements comprise a number of discrete tongues.
13:
- The needle shield remover according to claim 12, wherein the tongues have an inclination in relation to the longitudinal direction in the proximal direction of the body.
14:
- The needle shield remover according to claim 12, wherein the at least one cut-out comprises a plurality of longitudinally extending cut-outs that are arranged between adjacent tongues.
15:
- The needle shield remover according to claim 10, further comprises a second cut-out adjacent the grip elements having a larger width than the at least one cut-out.
16:
- The needle shield remover according to claim 10, wherein a large third cut-out extends in the distal direction about halfway along the longitudinal extension of the body.
17:
- The needle shield remover according to claim 16, wherein a second cutout adjacent the grip elements is interlinked with the large third cut-out creating a band-shaped section at the distal end of the body.
18:
- The needle shield remover according to claim 17, wherein the band-shaped section having a larger width that constitutes generally half of the circumference of the body.
19:
- The needle shield remover according to claim 17, wherein the band-shaped section comprises two band-shaped portions formed on each side of the second cut-out.
20:
- The needle shield remover according to claim 17, wherein a proximal area of the band-shaped section is arranged with inclined surfaces.
21:
- The needle shield remover according to claim 10, wherein the attachment element comprises an outwardly extending circumferential flange.
22:
- The needle shield remover according to claim 21, wherein the flange is designed to fit with a grip part of a protective cap.
23:
