摘要:
The invention refers to a needle safety arrangement for protecting a hollow injection needle (4) of a syringe (3) after an injection, the needle safety arrangement comprising: a needle sheath (11) having essentially the shape of a hollow cylinder arranged to surround the needle (4), the needle sheath slidable in longitudinal direction with respect to the syringe (3) and biased in proximal direction (P) a sheath linkage (12), slidable in longitudinal direction a syringe carrier (7) for holding the syringe (3), the syringe (3) and syringe carrier (7) arranged for joint axial translation and rotation relative to the needle sheath (11), wherein the sheath linkage (12) comprises means (12.3) for restricting translation in proximal direction (P) with respect to the syringe (3) by abutting against the syringe carrier (11), wherein in an initial state the sheath linkage (12) is abutted against the syringe carrier (7) and latched to the needle sheath (11) for joint axial translation, wherein the syringe carrier (7) exhibits at least one cam (7.4) on its circumference, wherein the cam (7.4) is arranged to de-latch the needle sheath (11) from the sheath linkage (12) on rotation of the syringe carrier (7) so as to release the needle sheath (11) for being translated in proximal direction (P) and cover the needle (4).Linvention concerne un dispositif de sécurité pour aiguille pour protéger une aiguille dinjection creuse (4) dune seringue (3) après une injection. Le dispositif de sécurité pour aiguille comporte: une gaine (11) daiguille ayant sensiblement la forme dun cylindre creux, conçue pour entourer laiguille (4), la gaine daiguille étant coulissante dans la direction longitudinale par rapport à la seringue (3) et sollicitée dans la direction proximale (P) un couplage (12) de gaine coulissant dans la direction longitudinale et un support (7) de seringue pour supporter la seringue (3), la seringue (3) et le support (7) de seringue étant conçus pour la translation axiale commun
