摘要：
The invention relates to an auto-injector for administering a dose of a liquid medicament (M), comprising: an elongate housing arranged to contain a syringe, the housing having a distal end (D) and a proximal end (P) with an orifice, wherein the syringe is slidably arranged with respect to the housing, a drive 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 (P), and operating the syringe to supply the dose of medicament (M), and activating means arranged to lock the drive spring in a compressed state and capable of releasing the drive spring for injection, wherein the elongate housing comprises a distal portion and a proximal portion connected by a hinge, the portions rotatable about the hinge between an aligned position and a maximum opening angle, wherein the drive spring may be compressed by rotating the portions towards the maximum opening angle, wherein the activating means are arranged to lock the drive spring in the compressed state when the portions are rotated at least almost to the maximum opening angle and wherein a loading bay for holding the syringe is arranged in the proximal portion.
