Abstract

UN CIRCUITO PARA LA PLASMAFERESIS EXTRACORPORAL QUE USA UNA AGUJA SIMPLE UTILIZA UN FILTRO DE MEMBRANA (1) QUE SEPARA, BAJO EL EFECTO TMP (PRESION DE LA TRANSMEMBRANA), EL PLASMA DE LA SANGRE. EL FILTRO (1) TIENE DOS CONECTORES (1A, 1B) EN EL LADO DE LA SANGRE, UNO DE LOS CUALES (1A) SE CONECTA A UN CONDUCTO QUE FINALIZA EN UNA AGUA SIMPLE. UNA BOMBA PARA LA SANGRE SE POSICIONA A LO LARGO DE ESTE CONDUCTO. EL OTRO CONECTOR (16) SE CONECTA A UN SEGUNDO CONDUCTOR (11) QUE SE DIRIGE A UN DEPOSITO DE SANGRE. UN CONDUCTO ADICIONAL (17) CONECTA EL LADO DEL PLASMA DEL FILTRO (1) CON UNA BOLSA PARA LA RECOLECCION DEL PLASMA (18). UNA BOMBA (19) SE ENCUENTRA SITUADA EN EL MENCIONADO CONDUCTO PARA MANTENER LA TMP A TRAVES DEL PROCESO COMPLETO. LA BOMBA (19) SE CONTROLA POR UN SISTEMA AUTOMATICO QUE MIDE LA PRESION, LOS NIVELES DE BURBUJAS, Y EL PESO DE VARIAS BOLSAS QUE SE USAN EN EL CIRCUITO.
