Abstract

Un dispositivo de separación sin membrana se puede aplicar en una diversidad de tratamientos, tal como la ultrafiltración de sangre para un paciente con una enfermedad renal en la etapa final. Un dispositivo de ultrafiltración puede incluir un dispositivo de separación sin membrana el cual separa el flujo de sangre entrante en un flujo de plasma sustancialmente libre de cuerpos citoplásmicos y la fracción remanente y una segunda etapa libre de dializado la cual separa selectivamente el exceso de fluido, toxinas y otras sustancias del flujo de plasma y regresa el plasma procesado al dispositivo de separación sin membrana. Un procedimiento de tratamiento puede incluir la ultrafiltración de sangre de un paciente utilizando el dispositivo de ultrafiltración y al realizar un tratamiento secundario sobre la sangre del paciente a una frecuencia reducida en comparación con el ultrafiltrado. El dispositivo de separación sin membrana también se puede aplicar al tratamiento, análisis y/o intercambio del plasma desde la sangre o se puede combinar con dializadores convencionales para realizar diálisis en una fracción de plasma libre de cuerpos citoplásmicos.
