Abstract
A syringe/needle combination comprising a leading tightly capped needle with a flanged conical hub; a hollow cylindroid with a leading interior cone slip-connecting to outside cone of the needle hub and containing an inside left hand-threaded Luer-Lok attachable to needle hub flanges, a cylindric body containing an elastomeric piston and a trailing end having inside and outside annular flanges; and a plunger with leading right-handed threads reversibly mating with right-handed threads inside the needle hub, a leading body passing through and securing the elastomeric piston, a trailing body separable from the leading body by breakage or right-hand threaded attachment, and a trailing end with a thumb-piece. If pre-filled with liquid medication, the user screws the trailing part of the plunger to the leading part, removes the needle cap, sticks the patient, empties the hollow cylindroid via the plunger-activated piston, advances and rotates the plunger thumb-piece clockwise to engage the needle hub, retracts the needle-linked plunger until the trailing end of the elastomeric piston is stopped by the trailing inside flange within the hollow cylindroid, breaks or screws off the trailing part of the plunger, and plugs the empty leading cone of the hollow cylindroid with the needle cap reversed.
