ABSTRACT:
A membrane plasmapheresis module (10) comprises semipermeable membrane means (11) capable of permitting blood plasma to pass therethrough while preventing the passage of blood cells, and sealed housing means (18, 19) defining a blood inlet port (43) and blood outlet port (44) positioned adjacent opposite ends of a first flow path (60) extending along one side of the membrane (11). The housing (18, 19) also defines a plasma outlet port (38) adjacent one end of separate, second flow paths (62) extending along the other side of the membrane (11). The membrane (11) may be folded together about a fold line (12) to define a pair of membrane portions (14, 16) lying against each other. The first flow path (60) extends between the membrane portions (14, 16) and the second flow path (62) may optionally extend between each membrane portion (14, 16) and a wall of the sealed housing means (18, 19), or alternatively an adjacent fold (12) of the membrane portion. A plasma outlet port (38) is defined through the housing (18, 19) at a position spaced from the membrane (11). Channels (21) are defined in the interior surface of the housing (18, 19) and positioned to face the membrane (11) to serve as a manifold to collect blood plasma from the second flow path (62). The above-described channel (21) also extends across the fold line (12) into flow communication with the plasma outlet port (38). Also, blood inlet and outlet ports (43, 44) may extend in telescopic relation with aperture ports (40, 42) in the housing for securence of the inlet and outlet ports (43, 44).
