摘要： The invention relates to a device for taking blood by capillarity and incorporating a filter and downstream therefrom, an absorbent material for separating a plasma phase of the blood from a cell phase. The device is characterized in that the filter comprises in succession: a prefilter (6) for spreading the blood over the surface of a first membrane (2) having pores of dimension lying in the range 0.1 μm to 5 μm, said membrane having no clumping agent; and said first membrane (2).

摘要： Disclosed herein is a device for sampling blood by capillarity for separating a plasma phase of the blood from the cell phase. The device is a strip and includes a filter having a membrane with no clumping agents, a prefilter for spreading blood over the surface of the membrane; and an absorbent paper downstream from the filter. The membrane is dimensioned to cover only a part of the surface of the prefilter and the migration of blood by capillarity within the prefilter takes place essentially lengthwise relative to the strip before blood comes into contact with the membrane.

摘要： A device for extracting a liquid phase from a suspension, the device being characterized in that it comprises: a main duct for conveying a flow of said suspension, the duct being of a length that is sufficient to enable a layer of said suspension to develop that is depleted in solid phase; flow disturbance means for disturbing the flow of said suspension, said means being provided in the main duct and being adapted to cause at least one recirculation vortex to form so as to increase locally the thickness of said depleted layer; and liquid extraction means disposed in a region of the device where said suspension is enriched in liquid phase as a result of said recirculation vortex.A method of extracting a liquid phase from a suspension, the method comprising injecting said suspension into such a device at a flow rate suitable for causing at least one recirculation vortex to be formed, and extracting a fraction of said suspension that is enriched in liquid as a result of said vortex.

摘要： A method of extracting a liquid phase from a suspension, the method comprising: injecting said suspension into a duct presenting a first section that is straight and a second section that is curved; and at the outlet from said curved section of the duct, extracting a liquid-enriched fraction of said suspension that is spatially separated from a particle-enriched fraction of the suspension; the method being characterized in that the injection flow rate of the suspension and the geometry of the duct are selected in such a manner that: in the straight section, lift forces cause particles to be superconcentrated in a ring around the longitudinal axis of the duct; and in the curved section, Dean secondary flows deform said ring and give rise to spatial separation between said liquid-enriched fraction and said particle-enriched fraction. A device for implementing such a method.
