Abstract

UNA SOLUCION COLOIDAL DERIVADA, POR EJEMPLO, DEL SISTEMA CIRCULATORIO DE UN PACIENTE AFECTADO POR UN FALLO ORGANICO AGUDO Y/O CRONICO, Y EN LA FORMA DE ULTRAFILTRADO, PLASMAFILTRADO O TODA LA SANGRE, ES PURIFICADA DE TOXINAS, EN ESPECIAL PAF, BILIRRUBINA, ENDOTOXINAS, RADICALES LIBRES Y TOXINAS PROTEICAS, COMO INDOXIL-SULFATO, MEDIANTE DIALISIS A TRAVES DE UNA MEMBRANA SEMIPERMEABLE ADECUADA, PONIENDOSE EN CONTACTO LOS LADOS OPUESTOS DE LA MISMA CON LA SOLUCION PARA SER PURIFICADOS Y CON UNA SOLUCION DE LAVADO QUE CONTIENE UNA CONCENTRACION PREDETERMINADA DE LIPOSOMAS GENERALMENTE MAYOR QUE LOS POROS DE LA MEMBRANA SEMIPERMEABLE; LA UNIDAD DE DIALISIS PRESENTA UN PAQUETE DE FIBRAS HUECAS, ALTAMENTE PERMEABLES , CONECTADAS DE FORMA INTERNA A UN PRIMER CIRCUITO QUE CONTIENE LA SOLUCION PARA SER PURIFICADA, Y QUE SE SUMERGE A CONTRACORRIENTE DE LA SOLUCION DE LAVADO QUE CONTIENE LIPOSOMAS; LA SOLUCION DE LAVADO CIRCULA EN UN SEGUNDO CIRCUITO QUE PRESENTA ELEMENTOS PARA PERMITIR LA ENTRADA DE LIPOSOMAS EN LA SOLUCION DE LAVADO, Y HACE POSIBLE LA EXISTENCIA DE UN CARTUCHO DE PERFUSION EN SERIE CON EL SEGUNDO CIRCUITO Y EN EL QUE LA SOLUCION DE LAVADO QUE CONTIENE LOS LIPOSOMAS SE FILTRA A TRAVES DE UN FILTRO DE CARBON ACTIVADO O PARTICULAS DE RESINA SINTETICA CUBIERTAS CON MEMBRANAS DE FOSFOLIPIDOS CONTINUAS.
