Abstract

SE PRESENTA UN MODULO PARA EL MUESTREO DE FLUIDOS PARA SU UTILIZACION EN SISTEMAS DE MONITORIZACION DE FLUIDOS EN TIEMPO REAL. EL MODULO MUESTREADOR DE FLUIDOS PUEDE UTILIZARSE COMO UN MODULO DE ENTRADA DE UREA EN UN TRATAMIENTO DE HEMODIALISIS. EL SISTEMA DE MONITORIZACION DE LA HEMODIALISIS CUANTIFICA LA VELOCIDAD Y LA CANTIDAD DE LA UREA ELIMINADA DURANTE EL TRATAMIENTO DE HEMODIALISIS MIDIENDO LAS CONCENTRACIONES DE UREA COMO FUNCION DEL TIEMPO EN EL GASTO DEL EFLUYENTE HEMODIALIZADO DE UNA MAQUINA DE HEMODIALISIS. EL MODULO DE ENTRADA DE UREA SE INTERCONECTA CON LA CONDUCCION DE DESECHOS DEL EFLUYENTE HEMODIALIZADO DE LA MAQUINA DE HEMODIALISIS Y ELIMINA PERIODICAMENTE UNA CANTIDAD DEL EFLUYENTE AGOTADO PARA SU MEDIDA. EL MODULO DE ENTRADA DE UREA DETECTA LAS VELOCIDADES DE FLUJO Y ELIMINA ADICIONALMENTE LA BAJA VELOCIDAD DEL FLUJO. EL MODULO DE ENTRADA DE UREA INCLUYE UNA INTERCONEXION CON LA CONDUCCION DEL EFLUYENTE Y PREFERIBLEMENTE INCLUYE UN FILTRO ENTRE EL MODULO DE ENTRADA DE UREA Y EL SENSOR DE UREA.
