Abstract
The present invention provides a method of delivering an emulsion or suspension containing a supersaturated gas into a gas-depleted environment. The method generally comprises the steps of preparing an emulsion or suspension, exposing the emulsion or suspension to a gas at a pressure greater than 2 bar, and delivering the emulsion or suspension to a gas-depleted environment at ambient pressure.
Claims28
A method of delivering gas into a gas-depleted environment, comprising the steps of:
- a. emulsifying a first liquid having a solubility for a gas higher than the solubility of a second liquid for the gas, the second liquid being immiscible and having a solubility for the gas lower than that of the first liquid;
- b. exposing the emulsion formed in step (a) to the gas at a pressure of greater than 2 bar to form a gas-supersaturated emulsion;
- and
- c. delivering the gas-supersaturated emulsion to a gas-depleted environment at or near ambient pressure, thereby delivering the gas to the gas-depleted environment.
A method of delivering a gas to a gas-depleted environment, comprising the steps of:
- a. providing a gas-supersaturated emulsion comprising a first liquid having a solubility for a gas higher than the solubility of a second liquid for the gas, the first liquid being suspended in fine droplets within the second liquid, the second liquid being immiscible and having a solubility for the gas lower than that of the first liquid, wherein the first liquid is supersaturated with the gas;
- and
- b. delivering the gas-supersaturated emulsion to a gas-depleted environment at or near ambient pressure, thereby delivering the gas to the gas-depleted environment.
A method of delivering gas into a gas-depleted environment, said method comprising the steps of:
- a. preparing an emulsion comprising a first liquid having a solubility for a gas higher than the solubility of a second liquid for the gas, the first liquid being suspended in fine droplets within the second liquid, the second liquid being immiscible and having a solubility for the gas lower than that of the first liquid;
- b. exposing the emulsion to the gas at a pressure greater than 2 bar to form a gas-supersaturated emulsion;
- and
- c. delivering the gas-supersaturated emulsion through a tube to the gas-depleted environment at or near ambient pressure.
A method of delivering oxygen to biologic tissues, comprising the steps of:
- a. preparing an emulsion comprising perfluorochemical droplets suspended in glycerin;
- b. exposing the emulsion to oxygen at a pressure greater than 2 bar to form an oxygen-supersaturated emulsion;
- and
- c. extruding the oxygen-supersaturated emulsion onto the biologic tissues.
