  • Patent number: 7407472
    Abstract: A centrifuge apparatus for processing blood comprising a bottom spring-loaded support plate; a top support plate; an axial inlet/outlet for blood to be processed and processed components of the blood, the axial inlet/outlet being attached to the top support plate by a rotating seal assembly; a variable volume separation chamber mounted between the bottom support plate and the top support plate, the variable volume separation chamber being fluidly connected to the axial inlet/outlet; a pump fluidly connected to the axial inlet/outlet; and a rotary drive unit attached to the bottom support plate. The top support plate is fixed vertically and the bottom spring-loaded support plate is mounted on springs that maintain pressure on the variable volume separation chamber and allow the bottom support plate to move vertically.

  • Patent number: 4974879
    Abstract: A pass-through tube for use in conveying intravenous fluid to a patient in a pressurized chamber, the tube including a tubular body having an outer surface shaped and sized to sealably mate with the interior surface of a connector passing through the wall of a pressurized chamber, a first end having a first generally cylindrical surface adapted to sealably engage a similarly shaped surface of a mating first connector and first locking members for locking with mating locking members on the first connector, a second end having a second generally cylindrical surface adapted to sealably engage a similarly shaped surface of a mating second connector and second locking members for locking with mating locking members on the second connector. Also disclosed is a kit including a pass-through tube, a flexible internal tube, and a valve connected to the external end for connection to an intravenous supply line.
