  • Patent number: 4249923
    Abstract: A refrigeration and delivery system for chilling a cardioplegic fluid contained in a receptacle, for maintaining the fluid at a predetermined temperature and for delivering the fluid to a patient as needed. The refrigeration and delivery system consists of a refrigerator cabinet having an evaporator disposed in an internal chilling compartment for supporting the fluid receptacle. The evaporator has a heat transfer surface in direct engagement with the receptacle to facilitate the conduction of heat from the fluid to the evaporator. The receptacle has inlet and outlet ports connected by recirculation tubing which provides a flow path to recirculate the fluid insuring that chilled fluid is contained in the recirculation tubing. A discharge tube is connected to the recirculation tubing and when opened allows the chilled cardioplegic fluid to be administered to the patient.
