Abstract
Gaseous nanobubbles are created and infused into the blood stream to therapeutic effect such as oxygenation. The nanobubbles may be created inside or outside of the patient, either during infusion or prior to infusion. CO2 is extracted from the blood to improve oxygen.
Claims20
A method of infusing blood with a gas comprising:
- creating bubbles of gas in a medium;
- reducing said bubbles to nanobubbles, said nanobubbles having diameters of less than 500 nm;
- introducing said medium containing said nanobubbles into a bloodstream of a patient;
- and,
- rupturing said nanobubbles using external energy at a target location.
2 more elements
A system for infusing blood with a gas comprising:
- a gas source;
- a liquid medium;
- a gas infuser connected to said gas source and located in said liquid medium that creates gas bubbles when gas from said gas source flows through said gas diffuser;
- an ensonifier located in said liquid medium and connected to a power source wherein when energized said ensonifier reduces said gas bubbles to nanobubbles, said nanobubbles having a diameter of less than 500 nm;
- and,
- a catheter useable to deliver said nanobubbles in said medium to a bloodstream of a patient.
3 more elements
A system for removing CO2 from a bloodstream comprising:
- a first chamber useable to receive blood from a patient;
- a second chamber;
- a permeable membrane separating said first chamber from said second chamber;
- a vacuum useable to lower a pressure in said second chamber such that flow of CO2 from said blood through said membrane is increased;
- and,
- a flow pump connected to said first chamber on an input side of said flow pump and connected to said patient on an output side of said flow pump such that when energized, said flow pump delivers blood from said first chamber to said patient.
