ABSTRACT:
The present invention relates to mass transfer apparatus e.g., artificial kidney in which a semipermeable membrane is folded or pleated between top and bottom rectangular plates. Support members are disposed within each pleat on one side only of the membrane. The top and bottom plates are held under a predetermined compressive load while a connecting means with ports is bonded to the opposite side edges of the top and bottom plates. The whole pleated membrane assembly is secured within a housing, with the ports protruding through the housing. The apparatus has reproducible performance characteristics from one device to another.
