Abstract
Perfeccionamientos en los sistemas de difusión para sangre del tipo de los que tiene como medio de difusión una membrana semipermeable y flexible plegada en forma de pila para formar una serie de capas membranosas dispuestas para la circulación de sangre en una serie de primeras vías de flujo paralelas y para la circulación de otro fluido en una serie de segundas vías de flujo paralelas situadas entre las primeras y separadas de ellas por dicha membrana, y un refuerzo rígido e integral dotado de líneas entalladas transversalmente extendidas y generalmente paralelas, plegado por tales líneas en secciones y dispuesto a un lado de la citada membrana en las segundas vías de flujo para el soporte de las referidas capas, y aberturas espaciadas definidas en este refuerzo para permitir la circulación de fluido a través de ellas, estando dichos perfeccionamientos caracterizados por la disposición de lengüetas lateralmente situadas en cada borde del refuerzo rígido, estando dichas lengüetas plegadashacia dentro contra porciones internas del citado refuerzo y selladas a ellas para formar unas porciones marginales de doble espesor del mismo refuerzo y proporcionar un cierre hermético espaciador y de junta en bordes opuestos de la citada pila.
