ABSTRACT:
A two-phase mixture is provided having a dissolved gas and a suspension of bubbles in a liquid. Methods for making, maintaining, and using the two-phase mixture are also provided. The gas molecules may be introduced into the liquid at a high velocity under elevated pressure to form a supersaturated solution that retains the dissolved gas concentration in solution when the solution is exposed to ambient conditions. The mixture may be used in a number of applications where high concentrations of gas must be retained in solution during prolonged exposure to ambient conditions. An example of use is the treatment of wounds to non-surgically remove dead, devitalized, contaminated and foreign matter from tissue cells. The mixture may be combined with a plastic to encapsulate the suspension of bubbles to minimize liberation of the gas bubbles from the mixture.
