Abstract

EQUIPO PROVISTO DE UN SISTEMA OPTICO/ELECTRONICO QUE COMPRENDE UN DIODO LED (11) Y UN SENSOR FOTOSENSIBLE (12) CAPAZ DE RECIBIR LA RADIACION LUMINICA EMITIDA POR EL LED (11) Y DE PROPORCIONAR LA CORRESPONDIENTE SEÑAL ELECTRICA, Y DE UN CIRCUITO (15) PARA PROCESAR ESTA SEÑAL ELECTRICA. CUANDO ESTA EN FUNCIONAMIENTO, SE SITUA UN TUBO (5) A TRAVES DEL CUAL FLUYE LA SANGRE, ENTRE EL DIODO LED (11) Y EL SENSOR (12). EL EQUIPO ESTA PROVISTO DE UN CIRCUITO DE PRUEBA CAPAZ DE SER CONECTADO PERIODICAMENTE AL CIRCUITO DE PROCESAMIENTO QUE REEMPLAZA AL LED (11) Y AL SENSOR (12) CON EL OBJETO DE SIMULAR EL COMPORTAMIENTO DE ESTE ULTIMO Y PROPORCIONAR UNA INDICACION CONTINUA DEL HECHO DE QUE EL TUBO SE HALLA PRESENTE Y QUE LA SANGRE ESTA PRESENTE DENTRO DE EL, Y PARA COMPROBAR QUE LAS PARTES DEL EQUIPO MISMO FUNCIONAN CORRECTAMENTE.
