Abstract
A flexible clamp for IV tubing, and in particular for use in a free flow prevention system. The flexible clamp has a pair of generally elongate clamping arms defining a slot for receiving the IV tubing. The flexible clamp has a resilient bias tending to bring the clamping arms to a closed position wherein the IV tubing is squeezed between the clamping arms to close the lumen of the IV tubing to prevent fluid flow, and the clamping arms are movable against the resilient bias of the flexible clamp to an open position wherein the clamping arms are spread from one another relative to the closed position such that the lumen of the IV tubing is allowed to open so that flow through the lumen of the IV tubing is permitted. Complementary interlocking structures on the free ends of the clamping arms are brought into interlocking relationship when the clamping arms are brought to their closed position, thereby tending to prevent skewing of the free ends of the clamping arms out of the plane of motion of the clamping arms.
