FLUIDIC DEVICE
This abstract first appeared for US patent application 20250001328 titled 'FLUIDIC DEVICE
Original Abstract Submitted
a fluidic device that uses ultrasonic waves to trap microparticles contained in a fluid, the fluidic device includes: a body having a flow path through which the fluid flows and an ultrasonic element provided on a flow path wall forming the flow path of the body and configured to transmit ultrasonic waves in first direction to form a standing wave in the flow path, wherein the body has, with a portion where the ultrasonic element is arranged as a trapping section, an inflow section configured to cause the fluid to flow into the trapping section along a second direction intersects with the first direction, a first outflow section through which concentrated fluid containing microparticles trapped by the standing wave flows out from the trapping section, and a second outflow section through which diluted fluid having a concentration of the microparticles lower than that of the concentrated fluid flows out from the trapping section, the inflow section is provided at a negative side of the trapping section in the second direction, the first outflow section is provided at a positive side of the trapping section in the second direction, and the second outflow section is provided at the negative side of the trapping section in the second direction at a position different from that of the inflow section.
