    • Method and apparatus for controlling the pressure differential across the filter membrane (14) in membrane plasma filtration apparatus (12). Control means (26) in fluid communication with a plasma-containing fluid flow path (30) up-stream of the filter membrane (14) and cooperatively associated with the plasma filtrate flow path (32), is operable to vary the size of the plasma filtrate flow path (32) inversely with respect to changes in the pressure in the plasma-containing fluid, thereby maintaining the differential pressure substantially constant. The control means includes a movable surface (34) disposed for contact with fluid in the fluid flow path (30) upstream of the membrane (14), the surface (34) being movable upon pressure changes in the blood flow path (30) to vary the size of the plasma filtrate flow path (32). The movable surface (34) is biased to a normally open plasma filtrate flow path condition by a force of selected amount corresponding to the desired pressure differential.

    • A filter (10) and a method of filtering fluids. In the filter (10), a plurality of porous, hollow fibers (20) surround a central tube (18) and are contained by a housing (12). The ends of the assembly are potted with a sealant to define first and second sealant-impregnated ends (22, 24) having open flow paths through the hollow fibers (20) and central tube (18) from one end to the other. A manifold (16) defining a typically closed chamber covers one end of the assembly and another manifold (14) covers the other end and defines a fluid portal (26) to the tube (18) and hollow fibers (20). Fluid may be filtered by passing it through the pores of the hollow fibers (20) from the outside to the inside and draining fluid from the portal (26). Alternatively, filtering of a fluid may be accomplished by introducing fluid through the portal (26) and passing it through the pores of the hollow fibers (20) from inside to out.

    • Dialysis machine (10) adapted for operation with a negative-pressure-type dialyzer (12, 200). The machine (10) includes a flow system (14, 16, 26, 34, 36, 100, 46, 48, 52, 56, 58) having a negative pressure pump (56) for drawing fresh dialysis solution through a dialyzer (12, 200) under a controllable negative pressure and for discharging spent dialysis solution to a drain (58). A flow reversing valve system (100, 102, 104, 106, 108) is positioned in the flow system for cooperation with the dialyzer (12, 200) to selectively control the direction of dialysis solution flow within the dialyzer (12, 200) in either a first direction or a second reverse direction. The flow reversing valve system (100) is operative in a first mode to control direction of flow to and from the dialyzer in a first direction and in a second mode to reverse the direction of flow. The dialysis machine (10) also includes a very effective degassing system (16, 18, 20, 22, 56) which minimizes gas build-up on the dialysis solution side of the dialyzer (12, 200) so that when a hollow-fiber dialyzer (12) is used the normal dialysis solution flow is in a downward direction and blood flow is in an upward direction. The flow reversing system (100) may be integral with the machine (10) or may be a separate component for use with machines that do not include an integral or built-in flow reversing system. Finally, a method is disclosed herein for operating such a system which avoids the previous requirements for positioning and repositioning of the dialyzer during dialysis set-up.

    • An integral artificial kidney unit (and a process of making); formed of four opposed plastic sheets bonded together, the composition of the inner second pair of opposed thin sheets being selected for their high permeability to blood waste products in hemodialysis; is relatively easily made and has good diffusion characteristics. The inner second pair of bonded sheets provides an integral perfusion unit. The outer first pair of plastic sheets are bonded at their exterior edges, forming a dialyzate chamber (20), having an inlet port (22) and an outlet port (23), and also are bonded to a blood inlet tube (31) and a blood outlet tube (32) of the enclosed integral perfusion unit. More than one perfusion unit can be interconnected in parallel to a common blood inlet tube and a common blood outlet tube. Each integral perfusion unit has a single blood inlet port symmetrically disposed and interconnected to a blood inlet manifold, the inlet manifold disposed across and interconnected to multiple parallel blood tubules having small diameters. The blood outlet manifold is disposed across and interconnected to the termini of the multiple blood tubules opposite the blood inlet manifold. A blood outlet port is interconnected to the blood outlet manifold.

    • Un module de plasmapherese a membrane (10) comprend une membrane semipermeable (11) pouvant laisser passer du plasma sanguin au travers tout en empechant le passage de cellules sanguines, et une enceinte hermetique (18, 19) definissant un orifice d'entree du sang (43) et un orifice de sortie du sang (44) adjacents aux extremites opposees d'un premier chemin d'ecoulement (60) s'etendant le long d'un cote de la membrane (11). L'enceinte (18, 19) definit aussi un orifice de sortie du plasma (38) adjacent a une extremite de seconds passages separes d'ecoulement (62) s'etendant le long de l'autre cote de la membrane (11). La membrane (11) peut etre repliee suivant une ligne de pliage (12) pour definir une paire de portions de membrane (14, 16) reposant l'une contre l'autre. Le premier passage d'ecoulement (60) s'etend entre les portions de membrane (14, 16) et le second passage d'ecoulement (62) peut eventuellement s'etendre entre chaque portion de membrane (14, 16) et une paroi de l'enceinte hermetique (18, 19), ou alternativement un pli adjacent (12) de la portion de membrane. Un orifice de sortie du plasma (38) est defini au travers de l'enceinte (18, 19) en une position espacee de la membrane (11). Des canaux (21) sont definis dans la surface interieure de l'enceinte (18, 19) et positionnes face a la membrane (11) pour servir de collecteur de plasma sanguin provenant du second passage d'ecoulement (62). Le canal decrit ci-dessus (21) s'etend aussi au travers de la ligne de pliage (12) en communication d'ecoulement avec l'orifice de sortie de plasma (38). Egalement, les orifices d'entree et de sortie de sang (43, 44) peuvent s'etendre en relation telescopique avec les orifices d'ouverture (40, 42) dans l'enceinte pour la fixation des orifices d'entree et de sortie (43, 44).
