Abstract

Un aparato para la recogida continua de fracciones sanguíneas en el extremo de salida de un contenedor de centrífuga en el cual la fracción de glóbulos rojos y la fracción de plasma están separadas por una fracción intermedia que contiene glóbulos blancos y/o plaquetas, aparatos que comprende: medios que forman una cámara de recogida; medios de tabique a través de dicha cámara para bloquear el flujo de dicha fracción intermedia; primeros medios de lumbrera de retirada que se extienden dentro de dicha cámara hasta dicha fracción intermedia en el lado de aguas arriba de dicho tabique; y segundos medios de lumbrera de retirada en el lado de aguas debajo de dicho tabique que se extienden dentro de dicha cámara en la misma distancia que dichos primeros medios de lumbrera de retirada para retirar una combinación de dichas fracciones de glóbulos rojos y de plasma.
