<p>PCT No. PCT/EP93/02049 Sec. 371 Date Mar. 16, 1995 Sec. 102(e) Date Mar. 16, 1995 PCT Filed Jul. 31, 1993 PCT Pub. No. WO94/06489 PCT Pub. Date Mar. 31, 1994Safety connector for infusion therapy for supplying several lines and having a casing (1) in which there is a chamber (4) that is bordered by an essentially cylindrical inside wall (5) of the casing into which several connecting channels (2) for joining infusion lines open and which has an outlet channel (9) for attaching an outlet line. The cylindrical outside wall of an elastic ring-shaped valve body is in contact with the inside wall (5) of casing (1) that surrounds chamber (4). The safety connector is simple and inexpensive and has an uncomplicated design. The cylindrical contact surfaces between the ring-shaped valve body and the cylindrical inside wall (5) surrounding chamber (4) result in a good seal for the non-return valves even at a low contact pressure. The sealing force can be determined even down to a very low pressure. Thus, for the first time a safety connector suitable for gravity infusion systems is available.</p> |
