ABSTRACT:
The present blood exchange apparatus comprises a plurality of main layers acked to form a package. Each main layer includes a membrane envelope enclosing an intermediate netting layer. Spacers space the main layers so that blood may flow between adjacent main layers and an exchange liquid may flow within the intermediate netting layers. The facing ends of a package are embedded in a pourable sealing compound in such a manner that the spaces between adjacent membrane envelopes are open. After securing the spacers to each facing end of the main layers, the spacers and thus the layers are connected and then dipped into a curable sealing compound. The spacers have corner extensions which extend out of the sealing compound. Holes in the corner extensions expose the intermediate netting layers.
