Abstract: A flow actuated valve includes a valve body, a diverter member, an actuator member, and a check disk. The valve body defines a first upper aperture, a second upper aperture, and a lower aperture. A check disk member connects to the actuator member to control the flow of fluid depending upon the direction of the flow of the fluid through the valve. When the check disk member is closed, the diverter member engages the actuator member to allow a first fluid to flow through the first upper aperture or to allow a second fluid to flow through the second upper aperture. In operation, the fluid is selected by changing the directional flow of the fluid to close the check disk member which causes the actuator member to engage the diverter member to either allow the first fluid source or the second fluid source to flow therethrough.

Abstract: An enteral pump system for delivering medical fluids unidirectionally includes a disposable fluid delivery set having a repeatable compression portion and an enteral feeding pump. The repeatable compression portion is helically coiled around a central axis to define a cylindrical shape. The compression portion is configured to pump a large volume of medical fluids per stroke. The compressing portion includes at least two adjacent tubing walls joined around the central axis for repeatable compression. The enteral feeding pump is configured to repeatedly and reliably compress the compression portion of the fluid delivery set along the central axis. In operation, the compression portion is repeatably compressed without distortion along the central axis by the enteral feeding pump to flow unidirectionally through the fluid delivery set.
