Abstract: A system utilizes an oxygenation device to generate a gas-enriched physiologic fluid and to combine it with a bodily fluid to create a gas-enriched bodily fluid. The oxygenation device may take the form of a disposable cartridge, which is placed within an enclosure. An electronic controller manages various aspects of the system, such as the production of gas-enriched fluids, flow rates, bubble detection, and automatic operation and shut down.

Abstract: A device generates a gas-enriched physiologic fluid and combines it with a bodily fluid to create a gas-enriched bodily fluid. The device may take the form of a disposable cartridge. The cartridge may include a fluid supply chamber for delivering physiologic fluid under pressure to an atomizer. The atomizer delivers fluid droplets into a gas-pressurized atomization chamber to enrich the physiologic fluid with the gas. The gas-enriched physiologic fluid is delivered to a mixing chamber in the cartridge where the gas-enriched physiologic fluid is mixed with a bodily fluid, such as blood, to create a gas-enriched bodily fluid.

Abstract: An apparatus and method for blood oxygenation is provided, advantageously comprising an extracorporeal circuit for the preparation and delivery of hyperoxic or hyperbaric blood. In one embodiment, an apparatus for gas-supersaturating fluids, e.g., physiologic saline, includes a chamber having a first inlet to receive the fluid; a second inlet to receive a gas, e.g., oxygen, from a gas supply that maintains pressure within the chamber at a predetermined level, advantageously about 600 p.s.i.; and an outlet advantageously coupled to a capillary assembly. An atomizer nozzle coupled to the first inlet advantageously creates within the chamber fine droplets of fluid into which gas diffuses to create the gas-supersaturated fluid, which collects within the chamber below the atomizer nozzle for removal via the outlet.
