Abstract
UN ANALIZADOR DE GAS OPTICO QUE COMPRENDE UNA FUENTE DE RADIACION (1) Y MEDRAS (8) PARA CONDUCIR LA RADIACION OBTENIDA DE ESTA FUENTE (1) A TRAVES DE UNA MUESTRA DE GAS Y UN NUMERO DE FILTROS OPTICOS (10A,10B,10C) QUE CORRESPONDEN AL NUMERO DE GASES ANALIZADOS, CADA UNO DE LOS CUALES PERMITEN A TRAVES DE UNA LONGITUD DE ONDA REPRESENTATIVA POR EL GAS PARTICULAR Y ESPECIALMENTE ABSORVIDO POR EL MISMO, A UN NUMERO DE DETECTORES (11A,11B,11C) QUE CORRESPONDEN AL NUMERO DE GASES ANALIZADOS. EL ANALIZADOR DE GAS DESCRITO ES PROYECTADO PRIMARIAMENTE PARA LA MEDICION DE GASES DE ANESTESIA, POR EJEMPLO, HALOTANO, ISOFLURANO Y ENFLORANO, DIOXIDO DE CARBONO Y GAS HILARANTE Y EN PARTICULAR EN CONEXION CON ANESTESIA PARA CONTROLAR AL PACIENTE Y ADMINISTRAR EL ANESTESICO. EL ANALIZADOR DE GAS ESTA CARACTERIZADO POR MEDIOS (8A,8B,8C) POR LA DIVISION DE LOS CAMINOS DE RADIACION DESPUES DE QUE PASEN DE LA MUESTRA DE GAS PARA EL PROPOSITO DE MEDIDAS SIMULTANEAS DE LAS CONCENTRACIONES DE GAS EN DETECTORES RESPECTIVOS.
