Patent ID: 8092413

Claim:
A biological fluid filtration system comprising: a blood container; a leukocyte depletion device, said leukocyte depletion device having an inlet and an outlet with a filter media disposed there between, said leukocyte depletion device being disposed downstream from said blood container; a first conduit, said blood container and said inlet of said leukocyte depletion device being in fluid communication through said first conduit; a blood-receiving container, said blood receiving container being disposed downstream of said leukocyte depletion device; a second conduit, said outlet of said leukocyte depletion device being in fluid communication with said blood receiving bag through said second conduit; a bypass line, said bypass line providing fluid communication between said blood container and said blood receiving container; said bypass line comprising a loop, said loop of said bypass line being configured to be disposed above said blood container at a sufficient height to prevent the passage of fluid around the leukocyte depletion device; and a one piece tube support device, said loop of said bypass line being disposed in said one piece tube support device, said one piece tube support device comprising a curvilinear channel of substantially circular cross-section and of a diameter substantially that of the bypass line for receiving the bypass line; and completely surrounding the bypass line, thereby being configured to prevent slippage of the bypass line and support substantially the entire weight of said biological fluid filtration system without substantially crimping said bypass line.
