    摘要： Method and apparatus for centrifugal blood component separation including temperature sensing in each of a plurality of separation cells. The temperature of unit of bloods over time is recorded. If the temperature of any of the units exceeds a pre-determined maximum, portions of the blood separation device may be cooled. A controller may determine which of the units to process first, generally proceeding from the warmest unit to the coolest. The order of unit processing may be changed during processing. The detected temperature may be used to calibrate a pressure sensor used to predict the volume of a component separated from a composite fluid by predicting the volume of the composite fluid from sensed pressure and predicting the volume of other separated components from sensed movement of the other components to collection bags.

    摘要： A flexible, disposable centrifuge bag for receiving and holding a fluid sample, comprising one or more tubes and upper and lower flexible sheets having doughnut shaped configurations. The upper and lower sheets are superimposed and completely sealed together at their outer perimeters to define an outer perimeter of the centrifuge bag. The inner perimeter of the bag defines a central core. The tubes are sandwiched between the upper and lower sheets and extend from the central core of the centrifuge bag. The upper and lower sheets are sealed together at their inner perimeters such that the tubes are sealed between said upper and lower sheets at the inner perimeter. The bag may be used to harvest platelet rich plasma from whole blood in either a batch method or while simultaneously infusing additional aliquots of whole blood into the bag during centrifugation.

    摘要： A system for automated operation of a blood separation system controlling the input of blood samples, the separation of blood components, and the discharge of the components. The system includes a blood reservoir and centrifuge for receiving blood samples and separating the blood components. A sensor determines when adequate separation has been achieved and a controller receives signals from the sensor to operate a centrifuge drive assembly to achieve desired separation. An input pump pumps blood samples to the blood reservoir, and an outlet pump removes separated samples from the blood reservoir. The inlet and outlet pumps are operated by the controller, and the inlet pump may be operated to discharge separated components not collected by the blood separation system, whereby additional sample volume is added for ongoing operation. One or more selected components are collected from a system outlet port by controlled application of suction to the centrifuge inlet port and the outlet port in response to sensing of alignment of the selected component with the outlet port.

    摘要： A method of harvesting platelet rich plasma from whole blood, comprising adding an aliquot of blood via the inlet tube of a rotating flexible centrifuge bag comprising inlet and outlet tubes sandwiched between doughnut shaped flexible sheets sealed together at the outer and inner perimeters. The whole blood separates radially into fractions. The distal end of the outlet tube is in flow communication with a desired fraction. The desired fraction is removed from the rotating bag via the outlet tube and withdrawal is terminated when an undesired fraction is detected to be near the distal end of the outlet tube. An alternative method comprises adding an aliquot of blood via the inlet channel of a rigid centrifuge container, said container having an interior collection chamber for receiving said whole blood and having a generally off-centered figure eight-shaped side cross-sectional configuration.
