Abstract
An apparatus and method for collecting whole blood and then separating it into components for subsequent use or storage. A self-contained bag set is used to collect the sample, which may then be placed into a device adapted to fit into a centrifuge for separation of components. Each component is then sequentially extracted according to density, with a sensor present in the device to control the operation of valves directing the collection of each component. The sensor may be reading one or more of the following characteristics: infrared, optics, density, weight, radioactive, fluorescence, color, magnetism, ultrasonic, capacitance wherein the characteristic is inherent in the blood and blood component or is an additive. Each component may then be separated into its own storage container. The preferred sensors include optics and weight. Besides blood density separation, the device may contain a solution including cells, proteins, subcellular particles or viruses which may be mixed with affinity media or antibodies prior to separation.
