Abstract

UN METODO PARA LA EXTRACCION DE LEUCOCITOS DE UN PREPARADO SANGUINEO QUE CONTIENE LEUCOCITOS QUE CONSISTE EN PREPARAR UN PREPARADO SANGUINEO CON POCOS LEUCOCITOS A BASE DE SOMETER EL PREPARADO SANGUINEO QUE CONTIENE LEUCOCITOS A UNA PRIMERA ETAPA DE TRATAMIENTO DE EXTRACCION DE LEUCOCITOS PARA EXTRAER AL MENOS EL 60% DE LOS LEUCOCITOS QUE SE ENCUENTRAN EN DICHO PREPARADO Y DE SOMETER EL PREPARADO SANGUINEO CON POCOS LEUCOCITOS A UNA SEGUNDA ETAPA DE TRATAMIENTO DE EXTRACCION DE LEUCOCITOS MEDIANTE EL USO DE UN ELEMENTO MICROFILTRANTE HECHO DE UNA TELA TEJIDA O NO TEJIDA QUE TIENE UN DIAMETRO DE FIBRA MEDIO DE 0,3 A 1,6 (MU)M. UN SISTEMA FILTRANTE PARA LA EXTRACCION DE LEUCOCITOS EN DONDE EL ELEMENTO FILTRANTE DE LA PRIMERA ETAPA ENTRA EN CONTACTO CON EL ELEMENTO FILTRANTE DE LA SEGUNDA ETAPA Y QUE SE ENCUENTRA EN EL LADO ASCENDENTE DEL ELEMENTO DE LA SEGUNDA ETAPA EN EL SENTIDO DE CIRCULACION DEL PREPARADO SANGUINEO QUE CONTIENE LEUCOCITOS QUE ESTA SIENDO TRATADO. EL METODO Y EL SISTEMA MENCIONADOS PUEDEN REDUCIR EL CONTENIDO DE LOS LEUCOCITOS QUE PERMANECEN EN EL PREPARADO A UN 10 ELEVADO -4 O MENOR Y TAMBIEN EL TAMAÑO DEL FILTRO.
