The present invention is directed to a fill or overfill control for a suction drainage system. More particularly, the present invention is directed to overfill protection (40) that is associated with the shut-off valve (30) for a suction drainage system so that flow of waste fluid to the disposable waste collection container (16) is stopped at a predetermined volume which is less than the container maximum capacity. Alternatively, the present invention is directed to overfill protection (40) that activates the suction drainage shut-off valve (50) at a volume of the disposable container (16) that is a sufficient volume less than the maximum capacity to allow a waste treating material such as a germicide and/or an absorbent to be added to the collected waste.

La présente invention concerne la commande du remplissage/débordement d'un système de drainage par aspiration. Plus particulièrement, la présente invention concerne une protection (40) contre le débordement, qui est associée à la valve de fermeture (30) d'un système de drainage par aspiration et qui fonctionne de manière que l'écoulement de fluide à éliminer vers le récipient jetable (16) destiné à recueillir ce fluide, soit arrêté à un volume prédéterminé qui est inférieur à la capacité maximale du récipient. Dans une variante, la présente invention concerne une protection (40) contre le débordement qui permet d'actionner la valve (50) de fermeture du système de drainage par aspiration, lorsque le volume dans le récipient jetable (16) est suffisamment inférieur à la capacité maximale, pour permettre l'addition au fluide recueilli d'un agent germicide et/ou absorbant.
