1. A method of flushing a vascular access device (VAD) comprising the steps of:
(a) providing a flush syringe assembly comprising
a barrel,
a luer tip
a threaded connection on the barrel surrounding the luer tip,
a sleeve external to the barrel having a distal end and an inside surface and an outside surface,
a hub comprising
a disinfecting system comprising a disinfectant contained in the hub,
a proximal end for releasably attaching the hub to a distal end of the sleeve and a distal end having a protective cover for releasably covering the disinfecting system
wherein the sleeve in combination with barrel and the hub form a sealed chamber, the sealed chamber housing the luer tip and the threaded connection
(b) removing the protective cover from the distal end of the hub thereby exposing the disinfectant contained in the hub;
(c) applying the disinfectant to a connector of the VAD;
(d) engaging the outside surface of the sleeve to eject the hub from the distal end of the sleeve;
(e) coupling the luer tip of the flush syringe assembly to the VAD;
(f) holding the flush syringe assembly and depressing a plunger rod disposed within the barrel to flush the VAD with a flush solution that is contained in a chamber of the barrel;
(g) decoupling the flush syringe from the VAD.
