Abstract

Se proporcionan dializadores que tienen un diseno de cabezal que proporciona un flujo de fluido mejorado, por ejemplo, sangre, al interior del dializador y especificamente al haz de fibras. El cabezal de entrada incluye un canal de entrada para proporcionar comunicacion fluida de un exterior del dializador a un interior del dializador, el canal de entrada define una trayectoria de flujo de fluido que es axial a un haz de fibras localizado en el interior del dializador. El dializador tambien incluye por lo menos un elemento para modificar la trayectoria de flujo de fluido de un fluido que salga del canal de entrada. Tambien se proporcionan metodos para proporcionar dializadores.
