Abstract

1283273 Fractionating blood; filter for blood AMICON CORP 5 Nov 1970 52788/70 Headings BID and B1X [Also in Division Fl] Blood is separated into a cellular fraction and plasma by conducting it under pressure along a flow path in contact with a porous filter membrane having effective pore diameters of from 0.1 to 0.8 micron. The depth of the path relative to the membrane is no more than 20 mils and the pressure applied to the blood is sufficient to maintain a pressure differential between the opposite faces of the membrane of from 1 to 15 p.s.i. and a flow velocity of whole blood over the membrane of from 2 to 50 feet per minute. Two apparatus for carrying out the process are also described. In that of Figs. 3, 4 (not shown) blood from a hypodermic syringe is forced through the membrane under controlled pressure applied by spring (72).
