Abstract

METODO Y DISPOSITIVO PARA MEDIR EL DIFERENCIAL DE FLUJO ENTRE EL FLUJO DE LIQUIDO ENTRANTE EN UNA MAQUINA DE DIALISIS Y EL FLUJO DE LIQUIDO SALIENTE DE UNA MAQUINA DE DIALISIS, ASI COMO UN METODO PARA CALIBRAR EL DISPOSITIVO. LA MAQUINA DE DIALISIS CONSTA DE UN CAMBIADOR DE CALOR (10) ORA LA TRANSFERENCIA DE ENERGIA TERMICA DESDE EL FLUJO DE LIQUIDO SALIENTE (29) AL ENTRANTE (8), UNA CONEXION (23,24) A UN DIALIZADOR (2) PARA ALIMENTAR LA SOLUCION DE DIALISIS A TRAVES DEL LUGAR DIALIZADO DEL DIALIZADOR, UN DISPOSITIVO (20, 28) PARA REALIZAR UNA ULTRAFILTRACION EN EL DIALIZADOR, Y UNA PLURALIDAD DE DETECTORES DE LA TEMPERATURA (30,31;32,33) PARA DETECTAR LA TEMPERATURA DE LA SOLUCION DE DIALISIS. EL DIFERENCIAL DE FLUJO SE CALCULA CON LA AYUDA DE LA ECUACION {DL}Q = Q X ({DL}T{SUB,1} - {DL}T{SUB,2})/{DL}T{SUB,2} DONDE {DL}Q = EL DIFERENCIAL DE FLUJO, Q = EL FLUJO DE LIQUIDO, {DL}T{SUB,1} = DIFERENCIA DE TEMPERATURA A TRAVES DE UN LADO DEL CAMBIADOR DE CALOR Y {DL}T{SUB,2} = DIFERENCIA DE TEMPERATURA A TRAVES DEL OTRO LADO DEL CAMBIADOR DE CALOR. LA CALIBRACION TIENE LUGAR CON UNAS BOMBAS DE CONCENTRADOS QUE HAY INCORPORADAS (6,16,18).
