Safety device for a pre-filled syringe and injection device

摘要

604078 A safety device (1) for a pre-filled syringe comprises a hollow support body (1.2) to retain the pre-filled syringe therein, a hollow needle shield (1.1) that is slidable relative to the support body and guiding means for guiding the movement of the needle shield relative to the support body. The guiding means comprise a deflectable flexible arm (1.1.4), a guide pin (1.1.3) and a guide track (1.2.2). The deflectable flexible arm extends essentially parallel to a central axis (A) of the safety device. The guide pin extends radial from the flexible arm. The guide track guides the guide pin within and along the guide track when the needle shield is slid relative to the support body.
