BLOOD CENTRIFUGE WITH SEPARATION, SENSOR AND DISPENSE CONTROL SYSTEM

摘要

A centrifuge includes integrated separation of blood components so that the separated products remain spinning within the centrifuge during the separation process. The centrifuge or an associated device (such as a computer) may include logic to determine the composition of the product produced by the centrifuge, while the centrifuge is running. The sensor system may include a particle counter capable of counting blood platelets and/or different types of blood cells. The sensor system may be capable of determining the hematocrit value of the blood. A dilution stage may be used to prepare the product measurement for the actual sensor. The dilution stage may include a weight measurement of the product, and the centrifuge may produce a sample for the sensor system. The weight measurement may be derived from a balance measurement of a spinning centrifuge. The measurement may include an optical measurement of collected and diluted volumes.
