Re-useable auto-injector with filling means

An autoinjector having a first subunit (110), such that the first subunit (110) comprises: a frame (111); a chamber (112) that is located in the frame (111) and has a proximal end and a distal end, an interior surface, and an outlet opening (114); a plug (113) that is positioned in the chamber (112) - movable - and that has an outer surface that is substantially in contact with the inner surface around its perimeter; and an inlet -or port- (118) that can be moved relative to the frame (111) and is attached to the chamber (112) in such a way that the movement of the inlet (118) causes a corresponding movement of the chamber (112) and the outlet opening (114) relative to the frame (111), such that the inlet is adapted to house or receive a container (119) containing a fluid; and so that, when the inlet (118) and the chamber (112) move relative to the frame (111), the plug (113) remains immobile with respect to the frame (111), so that the movement of the inlet (118) causes the movement of the outlet opening (114) relative to the plug (113); and also comprising: a diverting component -or displacement element- (121) that is attached to the inlet (118) and that is configured to displace or deflect the inlet (118), so that the outlet opening (114 ) deflects and moves away from the plug (113).
