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.

The present invention discloses an apparatus and a method for extracting a component in a solid by using nano-bubbles, the apparatus including a reaction container configured to hold a solid to be extracted, a nano-bubble generating device configured to generate a liquid containing nano-bubbles, and an energy generator, wherein the liquid containing nano-bubbles is used to be mixed with the solid to be extracted, and the energy generator is used to emit energy to the reaction container to burst the nano-bubbles and enhance the extraction effect of the solid in the liquid.

An apparatus configured to result in a penetration of one or more gasses into a dermis of biological skin, wherein the apparatus includes a fluid reservoir configured to contain an amount of a liquid in contact with a portion of a person's skin, and a nanobubble generator configured to inject nanobubbles into the liquid, wherein the nanobubbles contain the one or more gasses. The contact of the liquid containing the nanobubbles with the person's skin results in a cutaneous uptake of a gas contained in the nanobubbies into the person's skin, which may be beneficial in treating an ailment, such as diabetic peripheral neuropathy.

A nanobubble generator, a nanobubble-containing liquid solution comprising a substantially high concentration of nanobubbles, a system and methods of producing the nanobubble-containing liquid solution. The nanobubble generator includes an inflow portion for receiving a source liquid solution, a series of at least two sequential cavitation zones and shear planes to treat the source liquid solution and producing nano-bubble containing liquid solution, and an outflow portion for releasing the nanobubble-containing liquid solution.

Systems, devices, and methods are presented for optimizing the formation of gas nanobubbles in a disinfecting solution. In an example system for treating contaminated water, a centrifugal pump draws the water from a reservoir and circulates the water in and through a circuit of elements including a mixing chamber in the pump, a pressure vessel, a backflow valve, a Venturi injector, and a pair of nozzles immersed in the reservoir. The system injects ozone-rich gas into the fluid to produce an aqueous solution containing a volume of gas nanobubbles. The nozzles release the gas nanobubbles into the reservoir, creating highly reactive compounds that destroy organic compounds and other contaminants in the water.

A system may include a circulation subsystem and a circuit coupled to the circulation subsystem. The circuit may provide one or more signals to control the circulation subsystem to circulate a treatment solution including one or more of microbubbles or nanobubbles in a selected ratio. In one aspect, the nanobubbles may include a first gas, and the microbubbles may include a second gas. In another aspect, the treatment solution may include a first percentage of nanobubbles and a second percentage of microbubbles.

An ultrafine bubble generating apparatus and an ultrafine bubble generating method capable of efficiently generating an ultrafine bubble-containing liquid with high purity are provided. In order to this, a heating element provided in a liquid is caused to generate heat, and film boiling is made on an interface between the liquid and the heating element. A film boiling bubble is generated by the film boiling, and ultrafine bubbles are thus generated near the film boiling bubble.

An ultrafine bubble generating apparatus that generates ultrafine bubbles by causing a heating element to generate film boiling in a liquid includes: an element substrate including a heating part provided with multiple heating elements, in which the element substrate is configured to suppress variation of energies inputted to the heating elements in the heating part.

Provided are an ultrafine bubble generating apparatus and an ultrafine bubble generating method that can efficiently generate a UFB-containing liquid with high purity and can extend lifetime of the apparatus additionally. To this end, a shape of a bubble during generation thereof is partially restricted by forming walls around a heating element, and a position in which the bubble disappears is displaced from a position of the heating element.

Provided is an ultrafine bubble generating apparatus that generates ultrafine bubbles by generating film boiling by causing a heater provided in a liquid to generate heat, the ultrafine bubble generating apparatus including: an element substrate including a first heater that generates the film boiling in the liquid and a second heater that is arranged adjacent to the first heater, in which the first heater and the second heater are driven in different timings.
