  • Patent number: 5017192
    Abstract: A free flow prevention system for preventing free flow of fluid through IV tubing when the tubing is disconnected from an infusion pump. A flexible clamp is provided having a pair of clamping arms, which define a variable width slot for receiving the IV tubing. The IV tubing may be moved along the slot between a first position wherein the width of the slot is sufficient to permit the clamp to be positioned longitudinally along the IV tubing, and a second position wherein the width of the slot is normally less than the width of the slot at the first position. The clamping arms are resiliently biased to a closed position wherein the IV tubing is squeezed when in its second position to close the lumen to prevent fluid flow. A clamp-receiving passageway and clamp-opening wedge are provided on the infusion pump.
