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.

An IV administration system comprising: a first source of a first IV fluid; a second source of a second IV fluid; an IV control device having an inlet and an outlet for delivering IV fluids at a rate determined by a rate control signal and having a housing; a first flexible tube having a first end connected to the first source; a second flexible tube having a first end connected to the second source; a connector for connecting second ends of the first and second flexible tubes to the inlet of the IV control device; valve means positioned between the first and second sources and the connector and having the first and second flexible tubes passing therethrough for controlling fluid flow from the first and second sources to the inlet of the IV control device without contacting the first and second IV fluids, the valve means being manually settable to a first state in which the first tube is pinched off and the second tube is not, and being responsive to a valve control signal to change to a second state in which the second tube is pinched off and the first tube is not wherein the valve means maintains one of the tubes in a pinched off condition at all times; and wherein the valve means is normally deenergized in both its first and second states and is energized in response to the valve control signal to switch from the first to the second state; means for connecting the outlet of the IV control device to a patient; and control means located within the housing 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 predetermined volume has been delivered and the second IV fluid to the patient at a second rate until a second predetermined volume has been delivered.
