Blood component separation method and apparatus
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. Each component may then be separated into its own storage container.
1. An apparatus for use with a conventional centrifuge and a blood processing bag set, comprising, in combination:
a first pocket having an unenclosed top portion, said first pocket dimensioned to receive a blood processing bag;
means to support the blood processing bag in said first pocket, said support means located adjacent said unenclosed top portion of said first pocket;
a movable bottom portion below said first pocket, said movable bottom portion having an open position and a closed position;
a hinged portion located along a long axis of said first pocket, said hinged portion opening to allow access to said first pocket when said movable bottom portion is in said open position; and
a second pocket, wherein access to said second pocket is only possible when said movable bottom portion is in said open position.
2. The apparatus according to claim 1 wherein said first pocket further comprises a tapered bottom portion to hold the blood processing bag.
3. The apparatus according to claim 2 further comprising means to hold at least one auxiliary bag of a blood processing bag set.
