Abstract

Equipo de bombeo de sangre para circulación extracorpórea y asistencia ventricular. El equipo comprende una bomba de impulsión (5-5"'') con un émbolo desplazable (7), que adopta una configuración en forma de fuelle, situado en el interior de la misma, recibiendo la cámara de esa bomba la sangre venosa del paciente desde un reservorio (4). En la comunicación (16) entre el reservorio y la cámara se ha previsto una válvula de flotación (17) que cierra el paso cuando el émbolo (7) impulsa la sangre a través de una tobera (15), pasando por una válvula (22), a continuación a través de un intercambiador de calor (28) y seguidamente a través de un oxigenador (29) del que la sangre oxigenada es enviada de nuevo al paciente. El eje (9) del émbolo (7) es accionado por un mecanismo (14) que transforma los movimientos rotatorios y alternativos de un servomotor (12) en movimientos lineales, siendo el accionamiento de este servomotor (12) controlable mediante una consola computerizada, permitiendo proporcionar un flujo de sangre pulsátil de caudal y frecuencia regulables. El equipo forma una unidad fungible de un solo uso, empleado para suplir la acción de bombeo del corazón de un paciente cuando es sometido a una operación de cirugía cardíaca o asistencia ventricular.
