A surgical slush system for producing a sterile, semi-frozen slush from a sterile liquid. The system includes a slush generating unit having a cabinet with a plurality of louvres for air circulation, a basin at the top of the cabinet, a refrigeration means inside the cabinet for cooling the basin to a temperature below the freezing point of the sterile liquid, and a heating means for heating the basin to a temperature above the freezing point of the sterile liquid. A sterilized drape covers the basin. The drape is impervious to the sterile liquid and is sufficiently flexible to conform substantially to the interior shape of the basin with the sterile liquid being directly contained by the drape within the basin. An air filter in the form of a thin flexible sterilized sheet is fixed to and extends outwardly from the margin of the drape and is sized to extend over the louvres.
