Abstract
An autoinjector includes front and rear separable housing parts. These are connected by a rotary coupling action such as by bayonet coupling and the relative rotation action turns a needle shieldfrom a locked position in which it is both locked against longitudinal movement and acts as a shutter obscuring the contents of the syringe to an open position where the contents of the syringe are visible and the shield portion is freed for longitudinal movement. Connecting and securing the rear portionon the front portiontherefore unlocks the needle shieldfor operation. On completion of an injection, uncoupling of the front and rear portions returns the needle shieldto its locked position so the front portion may be disposed of safely.
