<p>METHOD OF MAKING MASS TRANSFER APPARATUS A method of manufacturing a mass transfer apparatus is disclosed, comprising the following steps: (a) making up an assemblage comprising a semipermeable membrane folded in accordion-like manner into a number of closely spaced pleats around support members inserted into or between the pleats on one side only of said membrane, the folded membrane and support members being interposed between two flat and rigid plates of uniform thickness; (b) introducing said assemblage between the two platens or a press movable with respect to each other, the opposing faces of the platens remaining constantly parallel during all positions of the platens; (c) exerting a predetermined and uniformlydistributed compressive load on said assemblage by means of said press; (d) connecting the opposite side edges of said lower and upper rigid plates of the assemblage by sticking, sealing, melting, welding, soldering, bracing, potting, casting, or the like, while said assemblage is maintained under said uniformly-distributed and predetermined load; and (e) sealing and housing said assemblage by any desired per se known means to form within such housing two compartments, one for blood and the other for dialysate, separated by the semipermeable membrane. A mass transfer apparatus having reproducible performance characteristics is thereby provided.</p> |
