Abstract
An automatic drug delivery device, for dispensing a fluid medicament, includes: a longitudinal housing; a removable cap; a syringe assembly having a hollow syringe body and an injection needle; and a drive mechanism. The loaded drive mechanism is operatively coupled with a safety shield movable within the longitudinal housing. The safety shield is biased into a proximal position in which it protrudes out of the proximal end of the longitudinal housing in order to cover a needle tip of the injection needle. The safety shield is movable into a distal position in which the injection needle is exposed for injection. The device includes a feedback mechanism providing a visual feedback to the user indicating an actual state of operation. The feedback mechanism includes a visual indicator which appears in a transparent window on the distal end of the housing.
