Abstract
A device for generating microbubbles may include a syringe having a barrel, a plunger and a syringe tip; a converging nozzle; and an aerator. The converging nozzle may have a coupling end, a converging tip opposite the coupling end, an exterior mating surface adjacent the converging tip, and an interior channel that fluidly couples the syringe tip and converging tip. The interior channel may have a diameter that progressively decreases from the coupling end to the converging tip. The converging nozzle may be coupled to the syringe tip. The aerator may have a retention end, a discharge end, an interior air chamber, an interior circumferential lip, and a discharge channel at the discharge end. The retention end may be coupled to the converging nozzle. The interior circumferential lip may abut the exterior mating surface. One or more air channels may fluidly couple the discharge channel and the interior air chamber.
