FLOW CHANNEL AND DEVICE FOR SEPARATION OF PARTICLES IN BODYFLUID

摘要

Disclosed is a device for separating particles in bodily fluids. In the flow channel according to an embodiment, the body fluid is injected in the inner region and all or part of the particles are separated, the inner region includes first and second inner regions, and the area of the cross-section of the first inner region is the second inner region It may be formed to be smaller than the area of the cross-section of the region. In addition, the apparatus for separating particles in body fluid according to an embodiment includes a flow channel and an acoustic wave generator, the flow channel provides a space in which a body fluid containing particles flows, and the acoustic wave generator controls at least one of particles and body fluid to generate an acoustic wave passing through the flow channel, the flow channel includes a main flow channel providing an inner region for injecting body fluid and separating all or part of the particles, the inner region including first and second inner regions may be formed such that the area of the cross-section of the first inner region is smaller than the area of the cross-section of the second inner region.
