MICROFLUIDIC DEVICE FOR SEPARATING LIQUID FROM THE SAME LIQUID CONTAINING DEFORMABLE PARTICLES WITHOUT EXTERNAL SOURCES OF ENERGY

摘要

The invention relates to a microfluidic device for separating liquid from the same liquid containing deformable particles without external sources of energy. The device comprises: at least one transport channel (1) using various fluid-hydrodynamic principles in order to increase the quantity of separated/obtained fluid; and at least one separating area (2) which diverts part of the fluid circulating via the transport channel towards at least one collection channel (3) or reaction chamber. The separating area (2) can include at least one pillar array, the configuration of which maximises the quantity of fluid extracted at once. The depth and width of the collection channel (3) are adaptable according to the requirements of the test to be implemented. The invention especially provides a filter for separating plasma from a drop of blood in a highly efficient manner, which can be used in portable blood testing systems.
