A new parallel plate dialyser. II. Description of design and in vitro performance

Using a high efficiency membrane support pattern, described in the previous paper, a prototype of a new parallel plate dialyser has been developed. The new dialyser is designed in such a way that the number of components is reduced to one item per blood layer and the membrane is folded as a continuum. This permits a semiautomatic assembly of the unit, which reduces production costs. Furthermore this technique facilitates aseptic handling of the item. The in vitro performance has been tested and it compares favorably with commercially available disposable parallel plate dialysers.
