A medical dye delivery system includes a medical dye container and a syringe for withdrawing the medical dye from the container and delivering the dye to a patient. A valve is disposed in the system having an inlet in flow communication with the medical dye container and an outlet in flow communication with the syringe. The valve includes a housing defining a flotation chamber with a valve seat and a flotation member disposed therein. The flotation member seals off the valve seat opening upon medical dye depletion, forcing any remaining fluid flow through a bypass channel that provides restricted flow to provide a tactile warning to the operator of the system that the medical dye container is depleted, yet allow the operator to, purge remaining dye from the system.

Système d'administration de colorant médical composé d'un contenant de colorant médical et d'une seringue servant à extraire la colorant médical du contenant et à administrer le colorant au patient. Le système comporte un clapet ayant une entrée en communication fluide avec le contenant de colorant médical et une sortie en communication fluide avec la seringue. Le clapet comprend une enceinte définissant une chambre de flottaison dotée d'un siège de clapet et d'un élément de flottaison placé à l'intérieur de celle-ci. L'élément de flottaison referme l'ouverture du siège du clapet après l'épuisement du colorant médical, ce qui force tout liquide restant à emprunter un canal de dérivation qui restreint écoulement de manière à fournir un avertissement tactile à l'opérateur du système pour l'informer que le colorant médical est épuisé, mais tout en permettant à l'opérateur de purger le système de tout colorant résiduel.
