Abstract:
1. An apparatus for the preparation and delivery of sterile medical ice slurry comprising: a blender for receiving a plurality of sterile slurry ingredient modules, said plurality of sterile slurry ingredient modules respectively containing a first predefined quantity of thermally conditioned sterile saline solution carrier liquid and a second predefined quantity of chunk ice; said blender including a thermally insulating blender container, a cutter blade contained within said thermally insulating blender container, and a blender cover; a blender outlet port disposed in a lower portion of said blender container; a slurry conditioning-agitator mechanical mechanism coupled to said blender cover; said slurry conditioning-agitator mechanical mechanism being positioned directly on a central vertical axis of said thermally insulating blender container and extending downwardly toward said cutter blade within said thermally insulating blender container, said slurry conditioning-agitator mechanical mechanism being moved up and down within the blender container to enhance mixing by substantially eliminating cavitations around the cutter blade, and controlling air entrainment in the sterile medical ice slurry by suppressing formation of an air entraining vortex in said thermally insulating blender container; said cutter blade being positioned at the bottom of the thermally insulating blender container; a slurry delivery tubing pump coupled to said blender outlet port by a slurry delivery pump tube; an associated injector tip connected to a discharge end of said slurry delivery pump tube, said associated injector tip being selected for a particular medical cooling application; a variable electric power transformer coupled to said blender controlling blender speed and precisely timed blender operation; and at least one thermocouple mounted inside said blender container for recording temperature.
