Apparatus and method for blood separation

摘要

The present invention is a blood separation system including a housing 1, a peristaltic pump 2, first, second and third clamps 3, 4, 5, an air bubble sensor 6, a centrifuge 7 and a touch sensitive control screen 8. Centrifuge includes a housing 9, a cover 10, drive device 11, a latch 12, an upper centrifugal bowl clamp 13 and a drain port 13. Centrifuge drive device 11 operates at a variable speed, rotating between about 1000 rpm and 6000 rpm in 100 rpm increments. Pump 2 is reversible and operates at variable speed to move fluid to and from the centrifuge 7. The screen 8 provides operator input to the blood separation system and provides output and operator instructions. The blood separation system is used to separate blood into solid cells when spun at a sufficiently high speed and allow platelets to elute from the solid cells when spun at a lower speed for predetermined time.
