Abstract

The present invention relates to an anti-free-flow valve (16) to prevent flu id free-flow through a tube assembly (14) having a lumen (30). The valve device (16) comprises a body (44) disposed inside the lumen (30) having a cylindric al portion (56) formed adjacent a tapered portion (60), the cylindrical portion (56) includes an opening (52) and the tapered portion (60) has a pair of beveled surfaces (62) with ends (48) that form a slit (50) therebetween. The slit (50) communicates with the opening (52) through a passage (64) formed through the body (44) of the valve device (16). When the tube assembly (14) is in a relaxed condition, the ends (48) of the beveled surfaces (62) confront one another and place the slit (50) in the closed position which prevents fluid flow through the passage (64) of the body (44) and through the valve device (16). When a tensile force (A) is applied along the tube assembly (14 ) in an area adjacent the valve device (16), the inner diameter of the lumen (30) decreases which elongates the body (44) and urges the ends (48) of the beveled surfaces (62) away from one another and places the slit (50) in the open position which permits fluid flow through the passage (64) and out the body (44) of the valve device (16).
