초록 ▼

A disposable blood separation set and a centrifugal blood processing system comprising a blood processing chamber adapted to be mounted on a rotor of a centrifuge; a frustro-conical cell separation chamber in fluid communication with the processing chamber, the cell separation chamber having an inlet, an outlet and a gravity valve inside the cell separation chamber. The valve is responsive to the gravitational field created by the speed of the rotor. When the rotor spins at high speed, the gravity valve may open the outlet at a location proximal to an axis of rotation of the rotor. When the rotor spins at a lower speed, the gravity valve may open the outlet at a location distal from the axis.

대표청구항 ▼

1. A disposable cell separation set comprising a fluidized-bed cell separation chamber adapted to be mounted on a centrifugal apparatus, said cell separation chamber having a generally conically main body, said main body being symmetrical around an axis with an inlet at an apex of the conically shaped main body and an outlet centrally located at a base of the main body, andan internal gravity valve mounted within said separation chamber and integral with said separation chamber, said gravity valve selectively allowing fluid flow through a first flow path near said inlet to said outlet and alternatively through a second flow path near said outlet of said separation chamber to said outlet. 2. The disposable cell separation set according to claim 1 wherein said gravity valve comprises a rod adapted to be displaced from said outlet toward said inlet centrally positioned around said axis. 3. The disposable cell separation set of claim 2 wherein said rod has a bore extending from a first end of the rod and one or more vents at a stopped end of said bore, whereby said bore and said one or more vents provide a fluid path into said separation chamber. 4. The disposable cell separation set of claim 3 further comprising a pipe extending from said inlet to a location near said vents in said rod, allowing fluid to flow from said inlet, through the pipe, out the vents and into the cell separation chamber. 5. The disposable cell separation set of claim 4 wherein said rod also comprises one or more conduits extending from the distal end to a proximal end of the rod. 6. The disposable cell separation set of claim 5 wherein the conduits are in fluid connection with the interior of the separation chamber through orifices at the first end of the rod and through a cavity at the second end to the rod. 7. The disposable cell separation set of claim 2 further comprising at least one spring acting on the rod of the gravity valve. 8. The disposable cell separation set of claim 2 wherein said rod comprises a lumen extending from a distal end to a proximal end of said rod. 9. The disposable cell separation set of claim 8 wherein said separation chamber further comprises a cup detachably supporting said distal end of said rod, said cup being affixed to said main body of said separation chamber between said inlet and said outlet. 10. The disposable cell separation set of claim 9 wherein said cup is mounted in a disc, said disc having at least one opening therein.
