Abstract

Dispositivo de acoplamiento rápido para tubos flexibles y tuberías que conducen fluido, especialmente de circuitos de sangre extracorporales, con una pieza de acoplamiento macho y una pieza de acoplamiento hembra (11, 12), que se pueden conectar entre sí de manera hermética a fluido, en el que en el extremo libre de la pieza de acoplamiento macho (12) está dispuesta una junta de estanqueidad (13), que se puede insertar en unión positiva y libre de juego en dirección radial y axial en una escotadura (14) formada de manera correspondiente de la pieza de acoplamiento hembra (11), que da como resultado, después de la conexión de las piezas de acoplamiento (11, 12), una transición libre de intersticio y libre de escalón entre los espacios huecos que conducen el fluido de las dos piezas de acoplamiento (11, 12), caracterizado por que las piezas de acoplamiento (11, 12) presentan una zona (16, 17) con un diámetro interior incrementado frente a las zonas de conexión del tubo flexible y en esta zona (16, 17) está previsto un orificio de ventilación (18) cerrable
