A multiple solution IV administration system includes a plurality of IV fluid sources which are connected by flexible tubing to the inlet of an IV pump. A sequence valve suspended from the tubing selectively pinches off all but one tube so that one source at a time is connected to the inlet. The sequence valve is controlled as a function of the accumulated volume pumped by the pump for each fluid and a stored volume limit for that fluid. When the accumulated volume of one IV fluid reaches its volume limit, the sequence valve is changed to connect a different source to the inlet of the IV pump. The desired volume limits and rates are entered manually and are checked automatically to protect against setup errors.

An IV administration system comprising: a first source of multiple doses of a first IV fluid; a second source of a second IV fluid; an IV control device for delivering IV fluids at a 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 first IV fluid to the patient at a first rate until a first volume has been delivered and the second IV fluid to the patient at a second rate until a second volume has been delivered; user-actuated means for entering numerical values representing first and second rates and first and second volumes to be used by the control means; and means for storing a required mathematical relationship between at least two of the numerical values; error check means responsive to the user-actuated means for providing an error signal if at least two of the numerical values fail to satisfy the required mathematical relationship.
