ABSTRACT:
Sterile surgical fluid is maintained at substantially its freezing temperature to prevent both melting and formation of solid ice pieces in surgical slush and to provide a supply of near freezing fully liquid phase sterile fluid as required. Slush is initially formed in a refrigeration mode wherein a basin containing sterile fluid medium is cooled to well below the freezing temperature of the medium to thereby rapidly lower the medium temperature. Upon formation of the slush the system is placed in a maintain mode wherein the container temperature is kept at or near the freezing temperature of the medium to selectively provide either slush or near freezing liquid. In the preferred embodiment the maintain mode is effected by electrically energizing one or more thermoelectric modules and de-energizing a refrigeration system in which the refrigerant fluid is passed through an evaporator disposed in thermal energy transfer relation to the basin. In alternative embodiments the refrigeration system itself is controlled to keep the container temperature at or near the freezing point during the maintain mode.
