APPARATUS AND METHOD FOR DISPERSING AND MIXING FLUIDS BY FOCUSED ULTRASOUND AND FLUID FEEDER FOR DISPERSING AND MIXING FLUIDS BY FOCUSED ULTRASOUND

A fluid feeder includes a fluid storage unit and a pre-treatment unit. The fluid storage unit provides a fluid flow path through which a fluid mixture of a hydrophilic fluid and a hydrophobic fluid flows. The fluid storage unit is connected through a plurality of connectors to the fluid flow path having a portion, in which an ultrasound focusing unit for focusing ultrasound to disperse and mix the fluids contained in the fluid mixture by focused ultrasound is mounted, to flow the fluid mixture in the fluid flow path and to flow the fluid mixture dispersed by the ultrasound focusing unit through the fluid flow path. In the pre-treatment unit, the fluid mixture is dispersed at micrometer scale and supplied to the fluid storage unit before the fluid mixture is stored in the fluid storage unit.
