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 twin port adapter having first and second feeding tubes, the twin port adapter having a body, including first and second input ports each configured to receive a portion of the first and second feeding tubes therein, respectively;
• and an output port in communication with the first and second input ports;
• and a feeding tube guide rotatably connected to the body and configured to secure the first and second feeding tubes within the body;
• a first check ball proximate the first input port, and a second check ball proximate the second input port, wherein the first and second check balls are configured as a check ball valve that acts to block fluid from moving in either direction within the first and second input ports and the first and second feeding tubes;
• the twin port adapter configured to position the first and second input ports 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 twin port adapter, the receiver configured to receive the twin port adapter with the central shaft positioned between the first and second input ports while the eccentric bearing is in a first position in which neither of the first and second input ports is compressed;
• wherein the eccentric bearing is moveable between the first position, a second position rotated 90 degrees clockwise from the first position in which the eccentric bearing compresses the first input port 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 port 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.
