Feed and flush delivery devices are described for use in switching between delivery of enteral feeding fluid and flushing / hydration fluid to a patient, with both fluids being delivered through the same closed system. The delivery devices are simpler, easier to use, and are more cost effective than known prior art valves and control devices. Independent feed and flush lines are typically received by the delivery device, which merges the two lines into a single end delivery line so that either feeding or flushing fluid, but not both at the same time, can be conveyed through the end line, as desired and selected by the user. The delivery device is loaded onto the pumping mechanism of an enteral infusion pump, and can be part of a cassette which is used in combination with a particular brand of infusion pump.
