Claim 13:
14. An injector device for drug delivery comprising:
a needle hub comprising an input port on a proximal end of the needle hub, wherein the input port is configured to be removably coupled with a luer connector at a distal end of a syringe, and wherein the input port comprises a luer connector comprising a female tapered surface and an end wall at a distal end of the female tapered surface;
a fluid passageway extending axially through the needle hub;
a volume displacing protrusion extending in a proximal direction away from the end wall of the input port, the volume displacing protrusion comprising a proximal end and a distal end, wherein the proximal end is further from the end wall of the input port, the volume displacing protrusion having an opening therein that is in fluid communication with and axially aligned with the fluid passageway extending axially through the needle hub, wherein the volume displacing protrusion is tapered such that an outer diameter of a distal end of the volume displacing protrusion is greater than an outer diameter of a proximal end of the volume displacing protrusion, the volume displacing protrusion comprising an axial length that is less than the outer diameter of the distal end of the volume displacing protrusion; and
a space between at least a portion of the volume displacing protrusion and a distal end portion of the female tapered surface.
