Abstract
The present invention relates an anti-free flow valve for a fluid administration systems having a tube assembly with a lumen formed through therethrough coupled to a pump. The anti-free flow valve comprises a body including a cylindrical portion having an opening and a tapered portion which has opposing beveled surfaces with ends that form a slit bounded by side walls. The opening communicates with the slit through a passage formed through the body which is adapted to receive the tube assembly therethrough. Fluid free flow through the tube assembly is prevented by the slit being placed in the closed position when the ends of the opposing beveled surfaces are urged together when the tube assembly is in a relaxed condition. However, when a tensile force is applied along the tube assembly the inner diameter of the lumen decreases which urges the ends of the opposing beveled surfaces away from one another and places the slit in the open position, thereby permitting fluid flow through the body.
