Needle shield remover and a medicament delivery device comprising the needle shield remover
A needle shield remover for assembly with a cap of a medicament delivery device, wherein the needle shield remover comprises a longitudinally elongated tubular body ( 10, 10′, 10″ ) having a plurality of structural features, wherein said plurality of structural features are symmetrically disposed on the tubular body ( 10, 10′, 10″ ), in relation to a plane of symmetry which is perpendicular to a longitudinal axis.
1. A needle shield remover for assembly with a cap of a medicament delivery device, wherein the needle shield remover comprises:
a longitudinally elongated tubular body;
a first annular protrusion that extends radially outward from a first end of the longitudinally elongated tubular body, wherein the first annular protrusion is configured for a first snap fit connection with an attachment structure of the cap;
a second annular protrusion that extends radially outward from a second end of the longitudinally elongated tubular body, wherein the second annular protrusion is configured for a second snap fit connection with the attachment structure, wherein the first annular protrusion and the second annular protrusion are symmetric with respect to a plane of symmetry that is perpendicular to a longitudinal axis of the needle shield remover;
a first group of gripping members at the first end configured to engage a distal surface of a needle shield when the second annular protrusion has the second snap fit connection with the attachment structure; and
a second group of gripping members at the second end configured to engage the distal surface of the needle shield when the first annular protrusion has the first snap fit connection with the attachment structure, wherein the first group of gripping members and the second group of gripping members are symmetric with respect to the plane of symmetry, wherein the plane of symmetry is located at mid-length of the longitudinally elongated tubular body.
2. The needle shield remover according to claim 1 ,
wherein at least one of the first group of gripping members and the second group of gripping members comprises a cut out formed from the longitudinally elongated tubular body.
3. The needle shield remover according to claim 1 ,
wherein each of the first group of gripping members and the second group of gripping members comprises a tongue formed from the longitudinally elongated tubular body.
4. The needle shield remover according to claim 1 ,
wherein each of the first group of gripping members and the second group of gripping members comprises a resilient, radially inwardly extending member.
5. The needle shield remover according to claim 1 ,
wherein the needle shield remover has rotational symmetry about the longitudinal axis.
6. The needle shield remover according to claim 1 ,
wherein each gripping member of the first group of gripping members and the second group of gripping members extends from the longitudinally elongated tubular body radially inward and towards the plane of symmetry and is configured to engage a circumferential side surface, or the second end, of the needle shield of the medicament delivery device.
7. A medicament delivery device comprising the needle shield remover according to claim 1 .
8. The needle shield remover according to claim 1 , further comprising the cap.
