Abstract
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.
