Tubing connector

Fluid delivery set

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. 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.

Peristaltic pump and fluid delivery set

Fluid delivery unit

A fluid delivery set has three lengths of flexible tubing. The first length of flexible tubing at one end is connectable to or integral with a supply container for enteral or parenteral fluid, and at the other end is connected to the inlet of a drip chamber. The second length of flexible tubing is connected at one end to the outlet of the drip chamber, and at the other end to the inlet of a retention/connector device that has about a 90.degree. bend therein. The third length of flexible tubing is connected at one end to outlet of the retention/connector device, and at the other end is connectable to or integral with a means for introducing an enteral or parenteral fluid into the body of a patient. Preferably, a tension responsive pinch valve is operatively associated with the second length of flexible tubing.
