Abstract: The Huber needle assembly employs a straight needle with a bent distal end and a sheath of frusto-conical shape that tethers a cap to the housing in which the Huber needle is secured. The cap is movable from the housing to have the sheath cover the needle and carries a torsion spring that has a leg that snaps across a bore in the cap through which the distal end of the needle passes to block a return movement of the needle through the bore.
