Zusammenfassung:	The disclosed subject matter includes a structure and method for making a dual-lumen needle from single lumen needles to take advantage of the much higher economies of scale. Variations include two needles joined by a flow junction and one needle and a single cannula joined by a flow junction. In addition disclosed are methods of using a dual-lumen needle in a two needle access for blood treatment is disclosed in which at least venous flow is provided through a dual-lumen needle with arterial flow just sufficient to provide air infiltration detection in the event of withdrawal of the dual-lumen needle.
