Abstract

Se describen un dispositivo y un método para el tratamiento de sangre, dispositivo que se puede usar junto con o en lugar de un riñón fallido. El dispositivo incluye una unidad de ultrafiltración para eliminar proteínas, glóbulos rojos y blancos y otros componentes de alto peso molecular, una unidad de nanofiltración para eliminar glucosa, al menos una unidad de electrodesionización para transportar iones del torrente sanguíneo y una unidad de ósmosis inversa para modular el flujo de agua, tanto a la sangre como a la orina. En una modalidad, se proporciona una unidad de electrodesionización especializada que tiene varias cámaras que definen varios canales de fluido diluido, cada canal lleno con una oblea de resina específica de iones, y electrodos en la extremidad del dispositivo y próximos a cada uno de los canales de diluido llenos de resina. Mediante la aplicación selectiva de voltajes a estos electrodos puede activarse o desactivarse la funcionalidad de transporte de iones de un canal de diluido dado.
