摘要:
The invention refers to a needle safety arrangement for protecting a hollow injection needle of a syringe after an injection, the needle safety arrangement comprising: a needle sheath having essentially the shape of a hollow cylinder arranged to surround the needle, the needle sheath slidable in longitudinal direction with respect to the syringe and biased in proximal direction (P), a sheath linkage, slidable in longitudinal direction, a syringe carrier for holding the syringe, the syringe and syringe carrier arranged for joint axial translation and rotation relative to the needle sheath, wherein the sheath linkage comprises means for restricting translation in proximal direction (P) with respect to the syringe by abutting against the syringe carrier, wherein in an initial state the sheath linkage is abutted against the syringe carrier and latched to the needle sheath for joint axial translation, wherein the syringe carrier exhibits at least one cam on its circumference, wherein the cam is arranged to de-latch the needle sheath from the sheath linkage on rotation of the syringe carrier so as to release the needle sheath for being translated in proximal direction (P) and cover the needle.
