Abstract

UNA CABEZA DE LECTURA DE DOBLE FUNCION PARA UN INSTRUMENTO DE REFLECTANCIA, SE SITUA EN UN ALOJAMIENTO (10) PARA EL INSTRUMENTO. SE INSTALA EN LA CABEZA DE LECTURA (10) UNA PRIMERA FUENTE DE LUZ (14) PARA EMITIR RADIACION PARA LECTURAS DE REFLECTANCIA Y OPTICAMENTE TRANSMITIR DATOS. ADEMAS, SE INSTALA UN PRIMER FOTODETECTOR EN LA CABEZA DE LECTURA (10), PARA DETECTAR O RECIBIR LECTURAS DE REFLECTANCIA. SE DEFINE EN LA CABEZA DE LECTURA UN PUERTO DE ACCESO DE INTERFAZ O FORMATO. SE DISPONE UN INTERFAZ (CONJUNTO DE DISPOSITIVOS Y CANALES QUE PERMITEN CONECTAR UNIDADES PERIFERICAS A UN ORDENADOR CENTRAL) QUE INCLUYE UN SEGUNDO FOTODETECTOR (28) PARA DETECTAR DATOS OPTICAMENTE TRANSMITIDOS POR LA PRIMERA FUENTE DE LUZ (14). TAMBIEN SE DISPONE DE MEDIO (32) PARA DECODIFICAR DATOS RECIBIDOS POR EL SEGUNDO FOTODETECTOR (28). SE PUEDE INCLUIR TAMBIEN UNA SEGUNDA FUENTE DE LUZ CON EL INTERFAZ PARA TRANSMITIR COMANDOS O DATOS AL PRIMER FOTODETECTOR. ASIMISMO SE DISPONE DE SOFTWARE (PROGRAMACION) PARACONTROLAR LA OPERACION DE LA PRIMERA FUENTE DE LUZ Y EL PRIMER FOTODETECTOR. EL INSTRUMENTO PUEDE USARSE PARA MEDIR NIVELES DE ANALITO, POR EJEMPLO, GLUCOSA, COLESTEROL Y SANGRE COMPLETOS. PUEDE HABER UNA RANURA DE ACCESO EN LA QUE UNA CINTA DE PRUEBA, CON SANGRE APLICADA A UNA O MAS ALMOHADILLAS, SE INSERTA DURANTE LA MEDICION DE REFLEXION, Y SE INSERTA EL INTERFAZ (12) PARA TRANSFERENCIA DE DATOS DURANTE LA TRANSFERENCIA DE DATOS.
