    Abstract: 1511819 Collapsible container for centrifuge INTERNATIONAL BUSINESS MACHINES CORP 6 Oct 1976 [21 Nov 1975] 41547/76 Heading B2P An annular, flexible, collapsible centrifuge container for fluid, e.g. blood, separable into fractions according to density comprises a plurality of radially separated expansible fluid channels 11, 23 in the form of concentric interrupted annuli, an inlet and at least one outlet at opposite ends of each channel, the inlet to one end of the innermost channel 23 being in the form of a tube 31 extending radially outward from within the central opening 7 of the annular container, and each outlet being in the form of a tube, e.g. 19, 21 or 29, extending radially inward from the other end of the respective channel to the central opening 7, the other end of each channel, except the outermost 11, being connected to the one end of the next channel. The container is formed from two annular pieces 1a, 1b of flexible plastics, e.g. P.V.C., sealed together by heat and pressure to form fluid-tight welds at 3, 5, 9, 13 and 15. The tubes 19, 21, 29 and 31 are moulded, welded or sealed through the weld 9. The radially inward region of the channel 23 is connected to the inlet end of channel 11 by a radial channel 25. In use, the container may be placed in the rotor of a centrifuge as described in Specification 1509667, the rotor cover having recesses to receive the channels 11 and 23 when expanded. Whole blood to be processed may be introduced into the inner channel 23 through the tube 31. Red cells are removed through the tube 29. Platelet-rich plasma is led through channel 25 to the outer channel 11 from which platelet-poor plasma and platelet concentrate are withdrawn through tubes 19 and 21 respectively. In a modification, instead of providing the channel 25 to connect channels 11 and 23, a further outlet tube may extend from the radially inward region of the portion 27 of annular channel 23 to the central opening 7 and be connected to a further inlet tube which extends from the opening to the adjacent end of the channel 11.

    Abstract: A fluid container particularly useful in a centrifuge system for separating the various fractions in blood. The container comprises two circular sheets of flexible material, having central openings therein. The outer peripheral edges are sealed together, as well as an annular portion extending outwardly from the central opening. A radial arcuate portion is sealed off, thereby providing an interrupted or discontinuous annular chamber. At one end of the interrupted annular chamber, an inlet tube is provided, extending outwardly from the central opening and communicating with one end of the interrupted annular chamber. At the other end of the interrupted annular chamber, there is provided a radially enlarged portion, which acts as a collection chamber for the various portions of the fluid separated by centrifugal force. The various portions, or fractions, will exist at different radial distances from the center of the bag. A plurality of outlet tubes extend radially outward from the center of the bag to open within the collection chamber at different radial distances. Through these outlet tubes, selected separated portions of the fluid are withdrawn from the bag.
