Abstract

SE PRESENTA UN METODO PARA SEPARAR EL PLASMA DE LOS GLOBULOS ROJOS Y UN DISPOSITIVO QUE UTILIZA DICHO METODO EN EL CUAL UN FILTRO DE BAJA PRESION SE INTERPONE EN EL CAMINO ENTRE UNA ENTRADA Y UN AREA DE REACCION. LA UNICA FUERZA DE MOVIMIENTO PARA EL MOVIMIENTO DEL PLASMA DESDE EL FILTRO HASTA EL AREA DE REACCION ES LA FUERZA DE CAPILARIDAD SUMINISTRADA POR UN CAPILAR TUBULAR. EL FILTRO SE SELECCIONA ENTRE FILTROS DE MICROFIBRA DE UNAS CARACTERISITICAS ESPECIFICAS, EL CUAL PUEDE FUNCIONAR EN AUSENCIA DE AGLUTINANTES, Y FILTROS CAPACES PARA SEPARAR GLOBULOS ROJOS AGLUTINADOS DEL PLASMA, LO CUAL REQUIERE EL USO DE UN AGLUTINANTE.
