Abstract

LOS TRANSDUCTORES DE PRESION FISIOLOGICA CONVIERTEN UNA PRESION APLICADA (POR EJEMPLO, LA PRESION SANGUINEA) EN UNA SEÑAL ELECTRICA QUE PUEDE VISUALIZARSE EN UN MONITOR COMO VALOR NUMERICO U ONDA CONTINUA. HABIENDOSE EMPLEADO DURANTE AÑOS LOS TRANSDUCTORES DE PRESION REUTILIZABLES, LAS INNOVACIONES EN LA TECNOLOGIA DEL ESTADO SOLIDO HAN HECHO FACTIBLES LOS TRANSDUCTORES DESECHABLES. EN CONCRETO, SE DESCRIBEN AQUI MONTAJES NO REUTILIZABLES CON TRANSDUCTORES DE IMPEDANCIA ADAPTADA PARA UTILIZAR CON MONITORES QUE ANTES SE EMPLEABAN CON TRANSDUCTORES REUTILIZABLES. EL SISTEMA DE TRANSDUCTOR DE PRESION PUEDE SER MUY RESISTENTE DEBIDO AL CUIDADOSO MONTAJE DEL DIAFRAGMA DEL TRANSDUCTOR Y LA CIRCUITERIA DE COMPENSACION INTEGRAL. ADEMAS, LA CONFIGURACION GEOMETRICA DEL RECORRIDO DEL FLUJO ES UNIFORME, LO QUE HACE FACIL LA ELIMINACION DE BURBUJAS EN LA UNIDAD.
