ABSTRACT:
The ends of bundles of microporous tubing may be potted in otherwise conventional manner for assembly as a diffusion device for oxygenation of blood, blood plasmapheresis, or the like. In accordance with this invention, prior to impregnating the bundle ends in sealant, the micropores of the capillary tubing are filled with a liquid capable of entering the micropores, with the result that air in the bores of the tubing cannot migrate outwardly through the micropores as the sealant impregnates the bundle ends. This, in turn, prevents the sealant from advancing into the bores of the tubing to the level occupied by the sealant outside of the bores of the tubing, so that the ends of the potted bundle may be transversely cut within the block of cured sealant to expose open bores of the tubing.
