Abstract

La cellule, pour extraire le plasma du sang fonctionne par filtrage du sang à travers une membrane poreuse. La cellule comporte deux membranes poreuses accolées 8, 10, enveloppées par deux feuilles souples étanches 4, 6. Les pores des membranes filtrantes ont un calibre de 0,1 à 2 microns environ. Le sang arrive par un orifice d'entrée 20, pour circuler entre les deux membranes filtrantes 8, 10, et ressortir par un deuxième orifice 22. Le plasma filtré ressort dans deux volumes 24, 26, respectivement situés entre chaque feuille étanche 4, 6 et chaque membrane poreuse 8, 10. Le plasma est évacué par un orifice de sortie 30 qui communique avec au moins l'un des volumes 24, 26, prévus pour le plasma filtré. Application aux appareils servant à prélever en continu le plasma sanguin, à partir du sang fourni par un donneur, auquel est restitué le sang appauvri en plasmaThe cell, to extract the plasma from the blood, works by filtering the blood through a porous membrane. The cell comprises two adjoining porous membranes 8, 10, enveloped by two waterproof flexible sheets 4, 6. The pores of the filter membranes have a size of approximately 0.1 to 2 microns. The blood arrives through an inlet orifice 20, to circulate between the two filter membranes 8, 10, and exit through a second orifice 22. The filtered plasma emerges into two volumes 24, 26, respectively located between each sealed sheet 4, 6 and each porous membrane 8, 10. The plasma is discharged through an outlet orifice 30 which communicates with at least one of the volumes 24, 26, provided for the filtered plasma. Application to devices serving to continuously take blood plasma from blood supplied by a donor, to which the blood depleted in plasma is returned
