Abstract
A phase change ice particulate perfluorocarbon slurry and a method and apparatus are provided for producing phase change particulate perfluorocarbon slurries. A known amount of perfluorocarbon liquid is provided. A set percentage of a phase change liquid and optionally other additives, such as oxygen or other cell protectants are added to the known amount of perfluorocarbon liquid. The phase change liquid and the perfluorocarbon liquid are mixed to produce an emulsion of small droplets of the phase change liquid in the perfluorocarbon liquid. The emulsion is cooled to produce the phase change particulate perfluorocarbon slurry. A phase change ice particulate perfluorocarbon slurry comprises a known amount of perfluorocarbon liquid and a set percentage of a phase change liquid added to the known amount of perfluorocarbon liquid. An emulsion is formed by the set percentage of a phase change liquid and the known amount of perfluorocarbon liquid. The phase change particulate perfluorocarbon slurry is formed by cooling the emulsion to a freezing point. The phase change liquid includes water or a saline solution. A set percentage of water is provided in a range between about 5% and 50%. A set percentage of saline solution is provided in a range between about 0.5% and 6.0%.
