Conventional closed system suction catheters have a valve with a housing within which a valve member is movable to control suction applied by the catheter. In the present invention the outlet bore is inclined at an angle to the inlet bore and opens into it via an aperture. A valve member comprises a rod member and a manually actuable plate extending longitudinally in an external channel along the housing between two walls. The rod member supports a resilient sleeve and its forward end is urged, by a spring, to engage a tapered seal within the housing forwardly of the aperture, thereby blocking flow through the valve. The valve is opened by sliding the plate rearwardly so that the valve member moves rearwardly of the aperture. A locking cap can be twisted to prevent movement of the valve member from its closed position.

Les cathéters d'aspiration classiques à réseau fermé sont munis d'une valve avec un boîtier à l'intérieur duquel une valve est mobile, afin de contrôler le niveau d'aspiration qu'exerce le cathéter. Dans la présente invention, l'orifice de sortie est incliné à un angle par rapport à l'orifice d'entrée et communique avec ce dernier par un évidement. La valve comprend une tige et une plaque actionnée manuellement, de forme allongée sur le plan longitudinal et qui s'étend dans un canal extérieur le long du boîtier entre deux parois. La tige soutien un manchon résistant et son extrémité avant, sous l'action d'un ressort, engage un joint conique dans le boîtier, devant l'évidement, de qui a pour effet de bloquer l'écoulement traversant la valve. Cette dernière est ouverte en faisant coulisser la plaque vers l'arrière, de telle sorte que la valve se déplace vers l'arrière de l'évidement. Un bouchon d'arrêt peut être tourné pour empêcher la valve de se déplacer de sa position de fermeture.
