ABSTRACT:
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.
