Abstract:
A quick disconnect, disposable needle and hub assembly comprising:(a) an elongate needle cannula having a proximal end, a distal end, and a sidewall therebetween, the cannula having a lumen therethrough; (b) a hub securely fixed to the proximal end of the needle cannula, the hub including a distal end with a tip projecting therefrom for fixing the proximal end of the needle cannula so that the needle cannula extends away from the distal end of the hub, a proximal end having an inlet projecting therefrom which is connectable to a supply line and wherein the inlet is continuous with the lumen of the needle cannula, and a collar having an array of internal luer lock threads projecting unitarily from the distal end of the hub in spaced concentric relationship about the tip; and (c) a fitting including an elongate body having a proximal end, a distal end, and a sidewall therebetween, the elongate body having a cavity therethrough wherein the elongate body having at its distal end a tip projecting therefrom and a collar having an array of internal luer lock threads projecting unitarily from the distal end of the fitting in spaced concentric relationship to the tip, the elongate body at its proximal end has external luer lock threads which engage the internal luer lock threads of the collar of the hub to form a seal between the side wall of the fitting and the tip of the hub so that the distal end of the needle cannula extends through the cavity of the elongate body parallel to the sidewall and extends away from the collar at the distal end of the fitting, and the elongate body having an inlet traversing the sidewall connectable to a supply line.
