Abstract

UN METODO DE FILTRACION DEL PLASMA PARA SEPARAR LA SANGRE EN PLASMA Y CORPUSCULOS CON EL FILTRO PRINCIPAL Y PARA EXTRAER LAS SUBSTANCIAS DE PESO MOLECULAR ALTO COMO COMPONENTES PERJUDICIALES A PARTIR DE DICHO PLASMA SEPARADO FILTRANDO DICHO PLASMA CON EL FILTRO SECUNDARIO, EN EL QUE SE LLEVAN A CABO UNA OPERACION PARA ABRIR LA CAMARA INTERNA DEL FILTRO SECUNDARIO AL AMBIENTE CON EL FIN DE REDUCIR LA PRESION DE CADA DETECCION DEL VALOR LIMITE DEL INCREMENTO DE PRESION PROVOCADO POR EL INCREMENTO EN LA TENDENCIA A LA OBSTRUCCION DE DICHO FILTRO Y UNA OPERACION MAS PARA LIMPIAR DICHO FILTRO SECUNDARIO A PARTIR DE LOS LATERALES DE LAS CAMARA INTERIOR Y EXTERIOR TRAS REDUCIR LA PRESION DE LA CAMARA INTERIOR, SE PUEDE REDUCIR, DE ESTE MODO, UNA PERDIDA DE PLASMA CAUSADA POR LA DESCARGA DE DICHO PLASMA AL EXTERIOR DEL SISTEMA DURANTE LA OPERACION DE DESOBSTRUCCION DEL FILTRO SECUNDARIO.
