Claim 0:
1. 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 coupled with a luer connector at a distal end of a drug reservoir, 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, wherein the luer connector comprises an inner diameter at the distal end of the female tapered surface where the female tapered surface intersects with the end wall;
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 comprising an axial length that is less than an axial length of the input port, the volume displacing protrusion having an opening therethrough that is in fluid communication with and axially aligned with the fluid passageway extending axially through the needle hub, wherein the volume displacing protrusion comprises an axial length that is less than the inner diameter of the luer connector at the distal end of the female tapered surface where the female tapered surface intersects with the end wall;
a space between at least a portion of the volume displacing protrusion and a distal end portion of the female tapered surface; and
a needle having a proximal portion, a distal portion, an exit port on the distal portion, and a lumen extending therethrough;
wherein:
the lumen of the needle is in fluid communication with the fluid passageway extending through the needle hub.
