Title: Blood processing centrifugal separation bowl and method for collecting plasma fractions
Inventor: PAGES ETIENNE
IPC: B04B7/08
Filed: 2000-06-05
Abstract: PROBLEM TO BE SOLVED: To produce efficiently purer plasma fractions at a relatively low cost by making a filter core cooperate with an outlet so that the first blood fraction may pass a filtration film before taken out from a bowl after reaching the outlet. SOLUTION: When a bowl is rotated continuously, blood is separated into individual layers by density. As total blood mixed with an anticoagulant is supplied further to a separation chamber 304 of the bowl, layers 340 and 344 grow, the surface 346 of a plasma layer 344, therefore, moves toward the central axis A-A. The surface 346 contacts the cylindrical side wall 330 of a filter core 328 at a certain point, and by the flow resistance of the filtration film of the side wall 330, the surface 346 of the plasma layer 344 begins to ascend the first sloped section 332 of the filter core 328. After passing the filter core 328, filtered plasmas 348 flow into the entrance of an effluent tube 320 and flow along the passage, and are taken out through an outlet port 244 communicating fluidally with the effluent tube 320.
