    Abstract: An apparatus for supplying an enteral or parenteral fluid to a patient is a cooperative assembly of a rotary peristaltic pump and a fluid delivery set. The peristaltic pump has (a) a housing and (b) a peristaltic rotor projecting from the housing on a rotatable drive shaft. The housing has first and second receptacles for retaining and supporting the fluid delivery set. The fluid delivery set has (a) a drip chamber, or sight chamber, (b) a plurality of lengths or segments of flexible tubing, and (c) fluid connection elements therefor. The fluid delivery set defines a fluid pathway from a supply container of the enteral or parenteral fluid to a connector element adapted to be connected to a device for introducing the fluid into the patient; wherein the retention/connector device defines a bend of between about 78 degrees and about 102 degrees within the fluid pathway, the retention/connector device is constructed to be retained in the second retentive receptacle in the pump housing with the fluid pathway extending substantially horizontally from the second retentive receptacle. Preferably the fluid delivery set has a tension responsive pinch valve to prevent bolus feeding in the event that the fluid delivery set becomes displaced from the pump housing.
