Abstract
Un grave problema en los adultos mayores son los efectos adversos luego de caídas no
atendidas inmediatamente. Según estadísticas, las caídas son uno de los principales
factores que ocasionan severos daños físicos, psicológicos y sociales, e incluso provocan la
muerte, en las personas de la tercera edad. Este problema es particularmente importante
dado el incremento porcentual de ancianos en la población mundial, así como por la
situación de vulnerabilidad y abandono en la que se suelen encontrar dentro de nuestra
agitada sociedad.
La solución propuesta reduce los efectos negativos de las caídas en ancianos mediante un
sistema portátil, no invasivo y de bajo costo, usando dispositivos electrónicos comerciales
disponibles en el mercado. Este sistema, adecuadamente sujeto a la persona, detecta la
caída y genera una alerta hacia un teléfono móvil. De esta manera, la persona que reciba la
alerta logra enterarse del evento y puede tomar acción inmediata para lograr la pronta
atención del anciano.
El tema de tesis contempla no solo el diseño e implementación integral del sistema, sino
también la realización de pruebas funcionales para determinar la eficacia del sistema. Las
pruebas son limitadas, o bajo condiciones controladas, dado el tipo de pacientes
involucrados.
El desarrollo del sistema incorpora el uso de dispositivos y tecnologías muy actuales, tales
como sensores de aceleración de tipo microelectromecánico (MEMS), microcontroladores
de uso industrial del fabricante ATMEL con interfaces seriales síncronas y asíncronas,
módulos Bluetooth para la comunicación inalámbrica del microcontrolador y la generación de
alarmas y envío de alertas por la red GSM de telefonía móvil usando mensajes cortos de
texto (SMS).
A major problem in older adults is the adverse effects of falling after unattended time. According to statistics, falls are a major factor in serious injury and even death in the elderly. This problem is particularly important given the state of prostration and oblivion founded the older person in our hectic society. The solution proposed to reduce the negative impact of falls in the elderly is a portable electronic system, noninvasive and low cost using commercially available devices on the market. This system, properly attached to the patient, have the capacity to detect the fall of the old and generate an alert via mobile phone. So, the person receiving it will take action and achieve the prompt attention of the elderly. The thesis project includes not only comprehensive design and implementation of the system, but also the execution of functional tests, as far as possible considering the type of patients involved, to determine the effectiveness of the system. The development of the system incorporates the use of very current devices and technologies, such as acceleration sensors of the type micro-electromechanical (MEMS), ATMEL industrial microcontrollers with synchronous and asynchronous serial interfaces, Bluetooth modules for wireless communication between microcontrollers and mobile phone and the generation of alarms and alerts sent by the GSM mobile network using short text messages (SMS).
