Fluid treatment apparatus

Abstract

Abstract 1467508 Dialysis apparatus RHONEPOULENC SA 31 May 1974 [1 June 1973 2 April 1974] 24260/74 Heading B1X [Also in Division D1] At least two hollow fibres of macromolecular fluid-permeable material are twisted together to form a cord, the resulting assembly being useful in fluid fractionating apparatus since the twisted formation creates turbulence inside and outside the hollow tubes. In Fig. 11 cords 100 constructed as above are placed parallel to one another between end walls 101 of epoxy resin. The cords and end walls are sealed into a container having a lid 103 and end caps 104, 105. The caps 104, 105 have inlet and outlet pipes 106, 107 in communication with the interior of the hollow fibres. The container has pipes 108, 109 communicating with the exterior of the fibres. Preferably not more than six hollow fibres are twisted together to form a cord. Applications of the apparatus include ultrafiltration, reverse osmosis and the dialysis and oxygenation of blood. Several methods of, and apparatus for, twisting the fibres together; and for causing such twisted assemblies to imbricate with one another are described and illustrated, see D1T.
