1. An IV administration system comprising:

  • a first source of a primary IV fluid;

    a second source of multiple doses of a secondary IV fluid;

    an IV control device for delivering IV fluids at a rate determined by a rate control signal;

    valve means for controlling fluid flow from the first and second sources to the IV control device as a function of a valve control signal;

    means for connecting the IV control device to a patient;

    control means for providing the rate control signal and the valve control signal to cause the IV control device to deliver the secondary IV fluid to the patient at a first rate until a first volume has been delivered and thereafter the primary IV fluid to the patient at a second rate until a second volume has been delivered;

    means for providing input signals to the control means which select values for the first and second rates and the first and second volumes;

    means for storing a mathematical relationship which interrelates the value of first volume with at least one other selected value; and

    means responsive to the input signals for preventing operation of the IV control device unless the first volume and one of the other selected values satisfy the mathematical relationship.
