Abstract

De acuerdo con la presente invención , se proporciona un aparato de tratamiento de plasma del tipo de aquello en que se filtra sangre integral a través de una membrana microporosa dotada de un tamaño de pro de 0,1 a 2 micras, formándose así un filtrado de plasma. La mejora comprende un conjunto de cámara filtrante que incluye la membrana microporosa y un soporte de una membrana de tratamiento. Entre ésta y su soporte es intercalada un agente de tratamiento del plasma, la citada membrana de tratamiento está espaciada de la membrana microporosa , formándose entre ellas una cámara de plasma. La membrana de tratamiento es accionable, para permitir una transferencia entre el agente de tratamiento y el plasma en la cámara de este último, se disponen medios para introducir sangre integral a un lado de la membrana microporosa y medios para retirar plasma tratado de la cámara del mismo. En la versión ilustrativa , el agente de tratamiento del plasma se pone en circulación entre el miembro de soporte de la membrana de tratamiento y esta última En la misma versión, el conjunto de la cámara filtrante del plasma está provisto de una entrada y una salida para sangre y de una salida de plasma. Un par de membranas microporosas forman entre ellas una trayectoria de flujo de sangre. Un primer miembro de soporte de membrana se halla situado a un lado del par de membranas y un segundo soporte al lado opuesto de las mismas. Entre cada uno de tales soportes y una de las membranas microporosas se sitúa una membrana de tratamiento.
