Biological fluid filtration system utilizing by-pass line and tube support device

A biological fluid filtration system comprising:

• a leukocyte depletion device, said leukocyte depletion device having an inlet and an outlet with a filter media disposed there between;
• a first conduit, 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 second flexible tubing, said second flexible tubing in fluid communication with said first conduit upstream of said leukocyte depletion device and with said blood receiving container, said second flexible tubing including a first tubing loop and a second tubing loop, said first tubing loop being configured to be disposed at a sufficient height to prevent the passage of fluid around the leukocyte depletion device, and second tubing loop being configured to be below said first tubing loop and above said leukocyte depletion device;
• and
• a tubing device, said first tubing loop of said second flexible tubing being disposed in said tubing device, said tubing device being configured to support substantially the entire weight of said biological fluid filtration system without substantially crimping said bypass line;
• wherein said tubing device comprises a two-part tubing device having a first portion and a second portion connected by a hinge.
