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.

Claims (14)

1. A method of enriching a bodily fluid with a gas, the method comprising the acts of:

(a) delivering a physiologic fluid under pressure from a fluid supply chamber of a housing to an atomizer disposed in an atomizing chamber of the housing;

(b) atomizing the physiologic fluid using the atomizer and delivering droplets of the atomized physiologic fluid into a pressurized gas within the atomizing chamber to form a gas-enriched physiologic fluid;

(c) delivering the gas-enriched physiologic fluid from the atomizing chamber into a pressurized mixing chamber of the housing by using the pressurized gas within the atomizing chamber; and

(d) delivering a bodily fluid to the pressurized mixing chamber to mix with the gas-enriched physiologic fluid to form a gas-enriched bodily fluid,

wherein said fluid supply chamber, atomizing chamber, and mixing chamber are housed within the same housing.

2. The method, as set forth in claim 1 , wherein act (a) comprises the act of:

pumping the physiologic fluid through a fluid outlet in the fluid supply chamber.

3. The method, as set forth in claim 1 , wherein act (b) comprises the act of: routing the physiologic fluid through a fluid inlet of the atomizing chamber when a fill valve being coupled to the fluid inlet of the atomizing chamber is open.

4. The method, as set forth in claim 1 , wherein act (c) comprises the act of: routing the gas-enriched physiologic fluid through a fluid outlet of the atomizing chamber when a flow valve being coupled to the fluid outlet of the atomizing chamber is open.

5. The method, as set forth in claim 1 , wherein act (d) comprises the act of:

delivering the gas-enriched physiologic fluid to the mixing chamber using a fluid delivery device disposed in the mixing chamber.

6. The method according to claim 1 , wherein the pressure in the pressurized atomizing chamber is greater than 200 psi.

7. The method according to claim 1 , wherein the pressure in the pressurized atomizing chamber is greater than 600 psi.
