Enteral feeding pump systems, valve assemblies therefor and fluid flow control methods for same

A flow selector valve assembly for an enteral feeding pump system, comprising:

• a disposable tube adapter made of PVC material having first and second input flexible tubing channels and one output tubing channel, wherein the first and second input flexible tubing channels are configured to receive two respective tubes connected to two fluid sources, and wherein the one output tubing channel is configured to receive an elastomeric peristaltic tube section which further connects to a tube that connects to a patient feeding tube to provide at least one of fluids and nutrients from at least the two fluid sources;
• the disposable tube adapter configured to position the first and second input flexible tubing channels in relation with a receiver, the receiver having a central shaft with an eccentric bearing such that at least a portion of the central shaft is received by and within the disposable tube adapter, the receiver configured to receive the tube adapter with the central shaft positioned between the first and second input flexible tubing channels while the eccentric bearing is in a first position in which neither of the first and second input flexible tubing channels is compressed;
• wherein the eccentric bearing is moveable among the first position, a second position rotated 90 degrees clockwise from the first position in which the eccentric bearing compresses the first input flexible tubing channel therein to prevent flow therethrough, and a third position rotated 90 degrees counterclockwise from the first position in which the eccentric bearing compresses the second input flexible tubing channel therein to prevent flow therethrough, and wherein the eccentric bearing is configured to be actuated by a digitally controlled motor within the enteral feeding pump system.
