    摘要: A centrifugal method, and corresponding system, for processing blood to collect platelet rich plasma. A separation chamber is filled with blood from a fill syringe by rotating the separation chamber at fill rotation rate and pumping the blood from the fill syringe. A soft spin is used to initially separate red blood cells from platelets by spinning the separation chamber at a soft spin rate. A percentage of the blood is drawn from the separation chamber back into the fill syringe to remove separated red blood cells. A second portion of the separated blood is drawn from the separation chamber until a red blood cell/platelet interface is detected. A hard spin is performed by spinning the separation chamber at a higher rate and connecting tubing is cleared of red blood cells by drawing a predetermined clearing volume. The platelet rich plasma is then collected in the collection syringe.

    摘要: A centrifuge (10) is provided with a cantilevered shaft (18) upon which the main drive rotor (26) is located. A bobbin (62) is attached to the planetary gear shaft (44), which is driven in planetary motion by the rotation of the rotor (26) and its toothed engagement with the shaft (18) of the cantilevered rotor . A flying lead section (72) extends from the bobbin (62) through an aperture in the cantilevered rotor (26). The arrangement provides a centrifuge structure which can handle higher rotational speeds while maintaining resolution. The flying lead section (72) provides a simple path for the inlet and outlet leads (84,86) which reduces dead volume and increases reliability. The bobbin (62) supports at least one coil (68). Rotor component (44) includes at least one bearing (50, 52). Attachment means (66) are provided removably to attach the bobbin (62) to the rotor component (44), the attachment means (66) enabling removal of the bobbin (62) from the rotor without removal of the or any bearing (50, 52) of the rotor component (44).

    摘要: A blood separation chamber (18) is provided for rotation about an axis. In one implementation, the blood separation chamber (18) comprises a base (388) that includes formed walls that define a hub (120). A separation channel (126) extends about the hub (120). Flow passages (142, 144, 146) extend between the hub (120) and the separation channel (126). The hub (120) enables attachment of external tubing to convey blood to and from the separation channel (126) through the hub (120). In another implementation, the chamber (18) includes an interior channel, which includes a recess (386) that extends outside the bounds of the walls establishing separation zone. The recessed interior channel (386) permits the yields of individual blood components separated in the chamber to be maximized without cross-contamination or contamination by other components present in the chamber (18).
