ABSTRACT:
A diffusion system for blood including a membrane diffusion device comprising a plurality of blood flow paths positioned in interleaving diffusion exchange relation, with second fluid flow paths positioned on opposite sides of semi-permeable membrane means. The first and second flow paths each communicate with an inlet and an outlet. Heat exchange means having an inlet and an outlet is connected at the inlet thereof to the outlet of the first flow paths. A rigid reservoir, also having an inlet and an outlet is connected at its inlet to the outlet of the heat exchange means. A blood flow circuit is defined through the membrane diffusion device, heat exchange means, and reservoir. The flow circuit defines an essentially constant width, perpendicular to the directions of blood flow, from its beginning to end, to provide a system having good flow distribution in combination with a low pressure drop.
