Abstract

Procedimiento y aparato de obtención continua de dializado para hemodiálisis, caracterizándose el procedimiento porque comprende las etapas de: (1) establecer una línea principal entre un suministro de agua y un riñón artificial que tiene un circuito de recirculación en la misma proporcionado con medios venturi de dializado, medios de bombeo de recirculación y medios medidores de conductividad; (2) establecer un flujo de agua en dicha línea principal hacia el riñón artificial y separar aire disuelto y burbujas para formar una corriente desaireada; (3) establecer suficiente succión en la garganta del venturi por recirculación de fluido a través del mismo para inyectar concentrado de dializado a la corriente desaireada en dicha garganta; (4) mezclar dicho concentrado con el fluido en recirculación en el venturi y en el circuito de recirculación; consistiendo dicho fluido de recirculación en una mezcla de agua y una porción de dicho dializado en una cantidad que supera a la cantidad de agua fresca alimentada a la citada línea principal en una cantidad del orden de 25 a 300% aproximadamente.
