Abstract:
Auto-injector for administering a dose of a liquid medicament includes a housing to contain a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament (M), the housing having a distal end (D) and a proximal end (P) with an orifice to apply against an injection site. A spring means, upon activation, can push the needle from inside the housing through the orifice and past the proximal end (P), operate the syringe to supply the dose of medicament (M), and retract the syringe with the needle after delivering the medicament (M). An activating means can lock the spring means in a pressurized state prior to manual operation and capable of, upon manual operation, releasing the spring means for injection.

Claim (Index 1):
Auto-injector ( 1 ) for administering a dose of a liquid medicament (M), comprising:\n an elongate housing ( 2 ) arranged to contain a syringe ( 3 ) with a hollow needle ( 4 ) and a stopper ( 6 ) for sealing the syringe ( 3 ) and displacing the medicament (M), the housing ( 2 ) having a distal end (D) and a proximal end (P) with an orifice intended to be applied against an injection site, wherein the syringe ( 3 ) is slidably arranged with respect to the housing ( 2 ), spring means ( 8 ) capable of, upon activation:\n pushing the needle ( 4 ) from a covered position inside the housing ( 2 ) into an advanced position through the orifice and past the proximal end (P), \n operating the syringe ( 3 ) to supply the dose of medicament (M), and \n retracting the syringe ( 3 ) with the needle ( 4 ) into the covered position after delivering the medicament (M), \n activating means ( 20 ) arranged to lock the spring means ( 8 ) in a pressurized state prior to manual operation and capable of, upon manual operation, releasing the spring means ( 8 ) for injection, wherein the spring means ( 8 ) is a single drive spring ( 8 ) in the shape of a compression spring arranged to be grounded at a distal end ( 8 . 1 ) in the housing ( 2 ) for advancing the needle ( 4 ) and for injecting the dose of medicament (M) via a plunger ( 9 ) and wherein the drive spring ( 8 ) is arranged to have its ground in the housing ( 2 ) switched to its proximal end ( 8 . 2 ) for retracting the syringe ( 3 ), characterized in that the activating means ( 20 ) is arranged as a trigger button ( 20 ) laterally arranged on the housing ( 2 ).
