Abstract

PROCEDIMIENTO Y APARATO DE PLASMAFERESIS POR FILTRACION.LA PLASMAFERESIS CONSISTENTE EN LA SEPARACION DEL PLASMA DEL RESTO DE LA SANGRE, SE LLEVA A CABO POR FILTRACION CON RENDIMIENTO ELEVADO DURANTE PERIODOS PROLONGADOS, LLEVANDO LA SANGRE SOBRE UNA SUPERFICIE DE MEMBRANA Y, DE FORMA CICLICA, PASAR PLASMA A TRAVES DE ELLA A UNA VELOCIDAD CRECIENTE, HASTA QUE SE OBTIENE EL NIVEL UMBRAL, PARA EN ESE MOMENTO REDUCIR EL PASO DEL PLASMA, REDUCIENDO LA DIFERENCIA DE PRESION DE LA TRANSMEMBRANA HASTA UN VALOR PROXIMO A CERO, DEJAR LIMPIAR LA MEMBRANA Y REINICIAR EL CICLO.EL APARATO CONSISTE EN UN MODULO DE FILTRACION (4) QUE SE CONECTA A UN PACIENTE (1) A TRAVES DE UNA BOMBA (2), SALIENDO LA SANGRE SIN PLASMA POR UNA SALIDA (5) DISTINTA DE LA SALIDA (6) DEL PLASMA, QUE ES BOMBEADO POR UNA BOMBA (10); UNA SERIE DE TRANSDUCTORES DE PRESION (7, 8, 9) VIGILAN LA PRESION EN LOS DISTINTOS PUNTOS.
