Diseño y evaluación de un sistema multimodal utilizando redes WSN y GPRS para telemedicina que permita transmitir y monitorear medidas fisiológicas en tiempo real.

Abstract

The objective was the design and evaluation of a multimodal system using WSN and GPRS networks for a telemedicine system, which allowed to help and improve the diagnosis, treatment and evaluation of the patients of the Integral Health Center of the ESPOCH. Sensors were used in telemedicine, to make possible the development of the electronic part using an Arduino board, digital processing, user interface and communication in a 3G network. A prototype of telemedicine with USB communication was elaborated for greater ease, which displays its information in real time in the application designed in the Delphi software so that the end user can observe the values that the sensors throw through the programming language of the Arduino plate, at the end a comparison between the manual and the automatic process is made through the system (The Network Simulator) NS-2. The result obtained in time value between the simulation and the manual taking of the human physiological measurements were of 26.5 vs 154.6s, obtaining a favorable result of 77.87%, allowing the multimodal system to be faster, more efficient and more effective, in taking measurement of physiological factors such as: pulse, temperature, respiration and oxygenation in the blood, concluding that this design allows obtaining result with greater ease at the moment of giving diagnoses to the patients of the hospital center analyzed. It is recommended to use the multimodal prototype in Telemedicine, for its reading of human physiological measurements in real time regardless of the distance and the environment where the patient is, providing a better attention to him/her in an effective and efficient way.
