Abstract
SISTEMA TONOMETRICO PARA DETERMINAR LA PRESION SANGUINEA. UN SISTEMA SENSOR DE TENSION POR CONTACTO CON TEJIDO INCORPORA UN MONTAJE SEMICONDUCTOR Y UN DIAFRAGMA CONTINUO PARA DETERMINAR DE FORMA NO INVASIVA LA PRESION SANGUINEA INTRA-ARTERIAL DE UN PACIENTE. EL SISTEMA INCLUYE UN DIAFRAGMA CONTINUO COLOCADO CONTRA EL TEJIDO DEL PACIENTE QUE CUBRE UNA ARTERIA SUBYACENTE. EL MONTAJE SEMICONDUCTOR ESTA COLOCADO MUY CERCA Y SEPARADO DEL DIAFRAGMA PARA IRRADIAR DIRECTAMENTE EL DIAFRAGMA CON RADIACION ELECTROMAGNETICA Y RECIBIR UNA PORCION DE LA RADIACION ELECTROMAGNETICA QUE ES REFLEJADA POR EL DIAFRAGMA CONTINUO. EL SISTEMA DESCRITO TAMBIEN UTILIZA UNA TECNICA PARA MINIMIZAR LOS ERRORES DEL SISTEMA ASOCIADOS CON LA DESVIACION POR TEMPERATURA Y EL ENVEJECIMIENTO DEL SENSOR.
