Abstract
Disclosed is an apparatus (10) for conducting the flow of multiple fluids. The apparatus (10) includes a novel design allowing for the crossover of two fluid conduit paths (12, 26) to allow for more flexibility in placement of fluid conduits and greater utility of space. The apparatus (10) can also include a novel design which enables testing of the apparatus for leaks in fluid conduit paths (12, 26) and which also identifies leaks during operation and prevents contamination of one fluid path with leaked fluid from another fluid path. The apparatus (10) is useful in applications for conducting the flow of multiple fluids, including in extracorporeal blood processing systems such as apheresis systems, blood oxygenation systems and hemodialysis systems.
