Abstract
A free flow prevention system for preventing free flow of fluid through IV tubing (12) when the tubing (12) is disconnected from an infusion pump (10). A flexible clamp (20, 20A) is provided having a pair of clamping arms (24, 24A), which define a variable width slot (26, 26A) for receiving the IV tubing (12). The IV tubing (12) may be moved along the slot (26, 26A) between a first position (28) (Figure 4) wherein the width of the slot (26, 26A) is sufficient to permit the clamp (20, 20A) to be positioned longitudinally along the IV tubing (12), and a second position (30) wherein the width of the slot (26, 26A) is normally less than the width of the slot (26, 26A) at the first position (28). The clamping arms (24, 24A) are resiliently biased to a closed position (Figure 2) wherein the IV tubing (12) is squeezed when in its second position (30) to close the lumen of the tubing (12) to prevent fluid flow. A clamp-receiving passageway (18, 188) and clamp-opening wedge (22) are provided on the infusion pump (10). The clamp-opening wedge (22) is movable relative to a clamp (20, 20A) received in the passageway (18, 18B) to an operating position (Figure 3), wherein the wedge (22) moves the arms (24, 24A) of the flexible clamp (20, 20A) against their bias to an open position (Figure 3) wherein the lumen of the IV tubing (12) is allowed to open to permit fluid flow during operation of the pump (10).
