1. A device for connecting multiple bulk compounding systems together in which each bulk compounding system precisely controls fluid transfer of at multiple solutions to a single receiving container, each solution being contained in a separate source container, each bulk compounding system including:

  • a manifold having an outlet fluid line in fluid communication with said receiving container;

    a plurality of fluid lines, each source container being in fluid communication with one of said fluid lines each of said fluid lines being in fluid communication with said manifold;

    pumping means for pumping solution in said plurality of fluid lines from each of said source containers to said receiving container;

    control means, including first means for sensing the weight of fluid in said receiving container, and second means including a peripheral interface means, said peripheral interface means having a first set of input signals for selecting an amount of fluid to be transferred from each source container to said receiving container, said peripheral interface means also having a first set of output signals for displaying the amount of solution to be transferred, and a second set of output signals for controlling said pump means to deliver a predetermined amount of solution from said source to said receiving container in response to the amount of fluid sensed in said container, wherein the improvement comprises;

    first electronic connector means for electronically connecting together said second set of output signals from more than one bulk compounding system to cause said plurality of bulk compounding systems to transfer said selected amount of fluids from said source containers to said single receiving container, said connector means having a multiplexer means for receiving said second set of output signals from each of said bulk compounding systems, and for generating a plurality of output signals to activate said pumping means for each of said bulk compounding systems.
