摘要：
Fluid pressure generating device (10) for a cardiac assist device with a blood pumping means, including the fluid pressure generating device (10): a housing (11) defining an interior volume (18), and with a substantially rigid first housing part (12), a substantially rigid second housing part (14), a third flexible housing part (16) extending between the first (12) and second (14) housing parts and an inlet / outlet port (15) connected to one of said housings and adapted for fluid communication with the blood pumping means, the third housing (16) having an external surface around its periphery, an internal surface opposite the interior (18) of the housing (11) and joining along an edge (16b) to the first housing part (12)； and a fluid that fills the inner volume (18) of the housing (11)； characterized in that a motor (20) is arranged in the inner volume (18) of the housing (11) and connected between the first (12) and second (14) housing parts, the motor drive (20) moving the first (12) and second (14) housing parts with respect to each other to generate fluid pressure changes in the inlet / outlet port (15), where one of the parts (14) of the parts of first (12) and second (14) housing is movable and the other part (12) of the first (12) and second (14) housing parts is fixed, the movable housing part (14) being exposed outside the device of cardiac assistance.Dispositivo generador de presión de fluido (10) para un dispositivo de asistencia cardíaca con un medio de bombeo de sangre, incluyendo el dispositivo generador de presión de fluido (10): un alojamiento (11) que define un volumen interior (18), y con una primera parte de alojamiento (12) sustancialmente rígida, una segunda parte de alojamiento sustancialmente rígida (14), una tercera parte de alojamiento flexible (16) que se extiende entre las partes de alojamiento primera (12) y segunda (14) y un puerto de entrada/salida (15) conectado a uno de dichos alojamientos y adaptado para una comunicación de fluido c
