Abstract
Perfeccionamientos en circuitos cerrados de dializado de ut9ilizad en hemodiálisis, del tipo que comprenden una porción de presión super-atmosférica que incluye medios para el suministro y separación de dializado y medios para separar ultra-filtrado y una porción de presión sub-atmosférica que incluye un hemodializador, caracterizados porque: (a) la porción super-atmosférica se constituye por una linea de suministro de dializado y una linea de evacuación de dializado, una porción de una linea de suministro de dializado fresco de riñón, y una porción de una linea de separación de dializado agotado de riñón, una 1 y una segunda unidad de cilindro que tienen medios para separar cada uno de dichos cilindros en dos cámaras a medida que dichos medios se mueven entre los extremos de dicho cilindro, teniendo cada una de la primera y segunda unidad válvulas y medios de conmutación interconectados eficaces para permitir simultáneamente que una de dichas unidades se llene de dializado fresco a media que se desecha dializado agotado, mientras la otra unidad se llena de dializado agotado a media que se suministra dializado fresco al citado riñón, y para alternar las funciones una vez que dichas válvulas se conecta al mismo tiempo, y ,medios de separación de ultra-filtrado conectados entre una de dichas lineas de dializado y dicha linea de evacuación de dializado, eficaces para extraer dializado de dicha linea y transferirlo a dicha linea de evacuación de dializado, y medios para accionar dichos medios de separación de ultra-filtrado, independientemente de los medios que accionan las citadas primera y segunda unidades de cilindro y medios de control remoto para controlar dichos medios de separación de ultra-filtrado, y un des-gasificador situado en la linea de suministro de dializado agotado adyacente a la cámara de dicha unidad de cilindro que ha de llenarse con el mismo y (b) la porción sub-atmosférica se constituye por una porción de una linea de suministro de dializado fresco de riñóny una porción de una linea de separación de dializado agotado del riñón, un riñón artificial que tiene una membrana capaz de permitir simultáneamente la diálisis y ultrafiltración de sangre y un par de puertas de entrada y salida de sangre y un par de puertas de entrada y salida de dializado, medios reductores de presión en la linea de suministro de dializado fresco a dicho riñón artificial, adyacentes a su puerta de entrada de dializado y medios para aumentar la presión en la linea de separación de dializado agotado del citado riñón adyacentes a su puerta de salida de dializado.
