Abstract
A device for regulating the flow rate of a fluid includes a housing containing a plurality of flow conduits fluidly connecting an inlet and an outlet, each of the flow conduits comprising a flow control tube () and a resiliently compressive occlusion tube (), wherein the flow control tubes are of substantially equal internal diameter. Each of the flow control tubes has a length associated with a different flow rate. A resilient flow-blocking element () is operatively associated with each of the occlusion tubes and is movable into a flow-blocking compression against its associated occlusion tube. An actuation mechanism () in the housing is operable: (a) to selectively engage and move one or more of the flow-blocking elements into the flow-blocking compression against its associated occlusion tube, and (b) to selectively be disengaged from any of the flow-blocking elements.
