An improved multiple fluid delivery system usable for the delivery of intravenous fluids to a patient from a plurality of fluid sources includes flexible tubing members for coupling the sources to a fluid junction member. The fluid junction member, wherein little or no interfluid mixing occurs, is coupled by an output conduit to a controllable pump. Output from the pump, via a further fluid flow conduit, can be coupled to the patient's catheter. The system can multiplex a plurality of different fluids. Spaced apart sequences of fluid quanta are injected into the output conduit from the fluid flow junction. The fluids are either mixed, or not, in the output conduit as desired. Operator interaction and control of the system can occur either through a display screen or by means of a bar code sensor. Hard copy records can be provided of fluid flow delivery schedules or other related information.
