Abstract

Dispositivo para producir de forma continua una fracción de sangre, el cual comprende una pila 45 de, al menos, dos placas 50, 55 que tienen, al menos, una superficie 102 con un canal de flujo sanguíneo 100 que mira a una superficie 82 con un canal de recogida 90 separadas por una membrana semipermeable 75 permeable selectivamente a la fracción de sangre, una entrada 26 para conducir sangre a cada canal de flujo sanguíneo y una salida 36 para sacar sangre de los mismos para establecer un recorrido de flujo sanguíneo longitudinal, teniendo cada canal de flujo sanguíneo una porción de distribución 110 para distribuir uniformemente sangre transversalmente al recorrido del flujo sanguíneo y una porción de transferencia 160 que se extiende longitudinalmente al mismo, estando cada canal de recogida sustancialmente en correspondencia con dicha porción de transferencia de dicho canal frontal de flujo sanguíneo para recibir la fracción de sangre que pase por una salida de fracción 95 para conducir la fracción de sangre desde cada canal de recogida, por lo que la fracción de sangre se transfiere continuamente desde la sangre que pasa por dicha porción de transferencia de cada canal de flujo sanguíneo a través de la membrana al canal de recogida adyacente a dicha salida de fracción.
