Abstract
A flow control system includes a control device for intravenous (IV) tubing or other flexible or compressible tubing, wherein selectors are depressed to cause different amounts of compression of the tubing to partially flatten or squeeze the tube, and, hence, to cause different flow-rates of liquid through the tubing. The flow control system may have a housing surrounding a portion of the tube and the selectors may be moveable in the housing away from the tube to an outward position and moveable in the housing to an inward position against and pressing on the tube so that the selector compresses the tube into reduced-cross-section shape to reduce flow through the axial fluid passage of the tube. The selectors may be positioned in series along the tube, with each selector contacting a different portion of the tube.
