摘要：
An auto-injector comprising a housing containing a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament. A spring capable of, upon activation: pushing the needle from a covered position inside the housing into an advanced position through the orifice and past the proximal end, operating the syringe to supply the dose of medicament, and retracting the syringe with the needle into the covered position after delivering the medicament. A trigger locks the spring in a pressurized state prior to operation and, upon manual operation, releasing the spring for injection. An interlock sleeve telescoped in the housing and translatable in longitudinal direction, wherein in a proximal position the interlock sleeve is arranged to be coupled to the syringe in the syringe's retracted position and wherein the interlock sleeve in its distal position is arranged to allow decoupling of the syringe.
