Needle shield remover
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.
1. 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;
at least one longitudinally extending cut-out at said distal area of said body adjacent and between the grip elements; and
a large cut-out that extends in a distal direction about halfway along the longitudinal extension of the body,
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 the at least one longitudinally extending cut-out adjacent the grip elements enables a generally radial outwardly bias of the grip elements during a pushing action that facilitates mounting of the needle shield remover on the needle shield, and wherein the proximal end is arranged with a connector for engagement with a grip part of a protective cap of the medicament delivery device.
2. The needle shield remover according to claim 1 , wherein the longitudinal extension of the body extends in a longitudinal direction in relation to a length of said needle shield such that when the needle shield remover is mounted on the needle shield, said grip elements will extend past a distal end wall of the needle shield.
3. The needle shield remover according to claim 1 , wherein the grip elements comprise a plurality of tongues.
4. The needle shield remover according to claim 3 , wherein each tongue of the plurality of tongues has an inclination in relation to a longitudinal direction in a proximal direction of the body.
5. The needle shield remover according to claim 3 , wherein the at least one cut-out comprises a plurality of longitudinally extending cut-outs that are arranged between adjacent tongues of the plurality of tongues.
6. The needle shield remover according to claim 1 , further comprising a second cut-out adjacent the grip elements having a larger width than the at least one cut-out.
7. The needle shield remover according to claim 1 , wherein a second cut-out adjacent the grip elements is interlinked with the large cut-out creating a band-shaped section at the distal area of the body.
8. The needle shield remover according to claim 7 , wherein the band-shaped section has a larger width that constitutes generally half of the circumference of the body.
9. The needle shield remover according to claim 7 , wherein the band-shaped section comprises two band-shaped portions formed on each side of the second cut-out.
10. The needle shield remover according to claim 7 , wherein a proximal area of the band-shaped section is arranged with inclined surfaces.
11. The needle shield remover according to claim 1 , wherein the connector comprises an outwardly extending circumferential flange.
12. The needle shield remover according to claim 11 , wherein the flange is designed to fit with the grip part of the protective cap.
13. A protective cap for a medicament delivery device, wherein the cap comprises:
an inside surface; and
the needle shield remover according to claim 1 arranged on the inside surface.
14. The protective cap according to claim 13 , wherein the cap is provided with a grip part.
15. The protective cap according to claim 14 , wherein the protective cap is designed so that a user gripping the grip part will move the protective cap and the needle shield remover so that the needle shield will be pulled off of the medicament delivery device .
16. A medicament delivery device comprising:
a medicament container with a needle;
a needle shield attached to and surrounding the needle; and
a needle shield remover according to claim 1 .
17. The medicament delivery device according to claim 16 further comprising a protective cap, where the needle shield remover is attached to the protective cap through the connector.
18. The medicament delivery device according to claim 16 , wherein the medicament delivery device is an injector.
