Abstract

Mediante esta invención se proporciona un sistema de control de presión negativa que permite un control muy preciso y sensible de la presión negativa que permite un control muy preciso y sensible de la presión negativa. Se dispone una válvula de chapaleta electromecánicamente controlada para el control de dicha presión. Se ha comprobado que esta válvula permite unos tiempos de respuesta muy rápidos en términos de la estabilización de la presión negativa en el sistema. Este rápido tiempo de respuesta (del orden de 30 segundos) ha resultado ser muy deseable desde los puntos de vista fisiológico, de la seguridad y/o de lo conveniente. Esta invención incluye también sistemas de alarma para la presión transmembranal, que impiden que la presión del dializado exceda a la de la sangre. Otra característica del sistema transmembranal a un nivel establecido o predeterminado durante el funcionamiento de la máquina y la de que en el caso en que no se reciba ninguna señal de la presión venosa o esta presión resulta negativa por debajo de un nivel predeterminado, el sistema produce una alarma e impide la continuación de la diálisis.
