1. A central venous catheter initialization and access system for initializing and accessing a venous catheter having multiple lumens, the system comprising:

  • a support base having a plurality of integrally-mounted syringes, the syringes being organized as discrete groups corresponding to individual lumens of a multi-lumen central venous catheter, each descrete syringe group being spaced from the other distinct syringe groups, each discrete group comprising at least a flush syringe and an anti-coagulant syringe;

    the support base having an integrally-mounted multi-position valve assembly;

    the multi-position valve assembly having a plurality of individual valve inlet ports in fluid communication with the respective individual syringes;

    the multi-position valve assembly having a separate valve outlet port for each discrete group of syringes;

    a plurality of mating connectors in fluid communication with the valve outlet ports for simultaneous connection of the valve outlet ports to individual lumens of a multi-lumen central venous catheter; and

    the valve assembly being manually actuable to selectively connect between one syringe of each discrete group and that group'"'"'s corresponding valve outlet port to facilitate sequential injection from the flush and anti-coagulant syringes into individual lumens of a multi-lumen central venous catheter.
