ABSTRACT:
In a convoluted-membrane type diffusion device for blood, such as a blood oxygenator, in which the membrane is supported by a stiff, folded, integral backing having port means for fluid flow therethrough. The backing is provided with laterally positioned tabs on each edge thereof, the tabs being folded inwardly against inner portions of the backing and sealed thereto. This provides double thickness edge portions of the backing to provide spacing and a gasket seal at opposed edges of the stack of convoluted membrane layers. The backing may be coated with thermoplastic material, which may be used as an adhesive to hold the tabs in folded double thickness relation with the rest of the backing.
