Abstract

EL PRESENTE INVENTO SE REFIERE A UN DISPOSITIVO Y A UN PROCEDIMIENTO DE CONTROL DEL EQUILIBRIO DE FLUIDOS DURANTE UNA SESION DE TRATAMIENTO EXTRACORPORAL DE SANGRE, TRATAMIENTO SEGUN EL CUAL SE RETIRA A LA SANGRE UNA CIERTA CANTIDAD DE LIQUIDO QUE SE COMPENSA POR LA INYECCION EN EL CIRCUITO EXTRACORPORAL DE UN LIQUIDO DE SUSTITUCION. SEGUN EL INVENTO, SE CREA UN CIRCUITO DE RECIRCULACION DE SANGRE (2,6,7,15) EN EL INTERIOR DEL CUAL SE SIGUE LA EVOLUCION DE LA PRESION (19). UNA DESVIACION DE LA PRESION EN EL INTERIOR DEL CIRCUITO DE RECIRCULACION MUESTRA UNA DESVIACION DEL EQUILIBRIO ENTRE LA CANTIDAD DE LIQUIDO RETIRADO DE LA SANGRE Y LA CANTIDAD DE LIQUIDO INYECTADO A LA SANGRE. EL PRESENTE INVENTO SE APLICA NORMALMENTE EN HEMOFILTRACION, HEMODIAFILTRACION Y PLASMAFERESIS.
