Abstract

LA INVENCION SE REFIERE A UN MEDIDOR (2) ADECUADO PARA UTILIZACION EN LA DETECCION NO INVASIVA DE LAS CONCENTRACIONES DE GLUCOSA EN EL CUERPO DE UN PACIENTE. DICHO MEDIDOR (2) INCLUYE AL MENOS TRES FIBRAS RECEPTORAS DE RADIACION (16) QUE SE EXTIENDEN ENTRE UN CUERPO MEDIDOR (12) Y UN ESPECTROGRAFO (2), SEPARADAS ENTRE SI DE FORMA PRACTICAMENTE UNIFORME Y ALINEADAS SEGUN UN PATRON FIJO PREDETERMINADO, EN EL CUERPO DEL MEDIDOR (2). EXISTEN MEDIOS TRANSMISORES DE LA RADIACION (10) QUE CONDUCEN DICHA RADIACION DESDE LA FUENTE DE RADIACION (4) Y SE EXTIENDEN DESDE DICHA FUENTE HASTA EL CUERPO MEDIDOR (12). DICHOS MEDIOS TRANSMISORES (10) SE CONFIGURAN EN FORMA DE ANILLO , CONDUCIENDO LA RADIACION EN UN AREA EN FORMA DE ANILLO, RODEANDO ADYACENTEMENTE A CADA UNA DE LAS FIBRAS RECEPTORAS (16). TANTO LOS MEDIOS TRANSMISORES (10) COMO LAS FIBRAS RECEPTORAS (16) TERMINAN EN EL CUERPO MEDIDOR (12) EN UNA ESTRUCTURA UNITARIA QUE PRESENTA UNA SUPERFICIE EXTERNA CONFIGURADA PARA ENTRAR EN CONTACTO CON LAPIEL DE UN PACIENTE. EL ANILLO TRANSMITE LA RADIACION DESDE LA FUENTE HASTA EL PACIENTE, EN AREAS QUE RODEAN PROXIMAMENTE A CADA FIBRA RECEPTORA (16). DICHAS FIBRAS (16) DETECTAN LA RADIACION TRANSMITIDA NUEVAMENTE HACIA EL EXTERIOR DEL PACIENTE, Y LA TRANSMITEN AL ESPECTROGRAFO (8).
