Abstract

The present invention relates to an anti-free-flow valve (16) to prevent fluid 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 cylindrical 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).

Claims

AMENDED CLAIMS
[received by the International Bureau on 03 January 2002 (03.01.02); original claim 24 amended; remaining claims unchanged (2 pages)]
19. The tube assembly (14) according to claim 18, wherein said insert (66) comprises: a body (68, 166, 276) having at least one opening (52) formed therethrough and at least one tab (72) extending from said body (68, 166, 276).
20. The tube assembly (14) according to claim 19, wherein said valve (16) further comprises at least one slot (65) formed along said passage (64) which is sized and shaped to receive said tab (72) and retain said insert (66) inside said passage (64).
21. The tube (14) assembly according to claim 19, wherein said body (68) has a generally thin oval shape.
22. The tube (14) assembly according to claim 19, wherein said body (166) has a generally elongated square shape.
23. The tube assembly (14) according to claim 19, wherein said body (276) has a generally elongated oval shape.
24. A method for preventing fluid free-flow in a fluid administration system (10) which is connected to a fluid source (40) and the fluid administration (10) system including a pump (12) and a tube assembly (14) having two ends and a lumen (30) formed therethrough, the fluid administration system (10) further including a valve (16) disposed within the lumen (30), the valve (16) comprising a body (44), the body (44) including a cylindrical portion (56) with an opening (52) formed at one end and a tapered portion (60) formed adjacent another end of the cylindrical portion (56), the tapered portion (60) including opposing beveled surfaces (62) with ends (48) that define a slit (50) between the ends (48), the method comprising the steps of: (a) attaching one end of the tube assembly (14) to a fluid source (40);
(b) attaching the tube assembly (14) to the pump (12) such that the tube assembly (14) stretches and elongates the body (44) of the valve (16); and
(c) attaching the other end of the tube assembly (14);
18
25. The method according to claim 24, wherein when the body (44) elongates said slit (50) is placed in an open position which permits fluid flow through said passage (64) of the body (44).
26. The method according to claim 24, wherein when one end of the tube assembly (14) is attached to the fluid source (40), the slit (50) is placed in a closed position which prevents fluid free flow through the passage (64) of the body (44).
27. The method according to claim 25, wherein when the slit (50) is in the closed position, the ends (48) of the opposing beveled surfaces (62) confront one another and prevent fluid flow through the passage (64) of the body (44).
28. The method according to claim 24, wherein attaching the tube assembly (14) to the pump (12) causes fluid to flow through the body (44) of the valve (16).
19 STATEMENT UNDER ARTICLE 19 (1)
Claims 19-23 and 25-28 are unchanged. Replacement claim 24 replaces the original claim which was deemed unsearchable under PCT Rule 39.1(iv). Replacement claim 24 eliminates the positive claim to a human, or part of the human
body.
