Abstract

A fluidic connector (10, 110) with a leak proof connection site (11, 111) that includes a first larger diameter portion (15 122), a second smaller diameter portion (16, 123) and a deformable buckling region (19, 124) that forms a part of both the first (15, 122) and second (16, 123) diameter portions where the two portions join. The first larger diameter portion (15, 122) forms a separate inner surface for receiving a plug (116) to securely seal off the connection site from fluid communication therethrough while the second smaller diameter portion (16, 123) is adapted to receive and securely seal different sizes of male adapters used for attaching a lumen. Finally, the deformable buckling region (19, 124) forms a structural buffer between the first (15, 122) and second (16, 123) diameter portions in order to maintain the diameter of the first larger diameter portion (15, 122) when the second smaller diameter portion (16, 123) is stretched out by prolonged insertion of a nonconforming male adapter. In addition, an adapter (132) is provided which permits flexibility in use and provides a redundant fluid seal, without exhibiting creep.
