Diseño e implementación de un prototipo multimodal en telemedicina para emergencia utilizando redes WSN y tecnología móvil para transmitir medidas fisiológicas humanas en tiempo real.

Abstract

It was designed and implemented a prototype multimodal in telemedicine for a system of emergencies in real time using wireless sensor networks (WSN) and mobile technology general packet radio service (GPRS) to transmit human physiological measures carried out in the School of Electronic Engineering, Telecommunications and Networks, in order to improve the response time in taking of human physiological measures same and send the information in real time to the health care professional or health center closest to the monitoring and diagnosis of patients. In the design and implementation of the multimodal prototype was built portable transmitter module responsible for human physiological measurements through wireless sensors such as: flow of air, body temperature, pulse and blood oxygen; the same that are incorporate into a plate Arduino UNO and an E-Health Sensor Shield, another receiver module whose location is fixed with a server computer to receive data and display them in the graphical programming LabView environment. Wireless communication between the modules was carried out by mobile phone (sending sms text messages) using two SIM900 GMS/GPRS modems. The graphical interface is responsible for extracting information from text messages received in the SIM900 GSM/GPRS modem and link it with the database called Medical Report, allowing to store the identity card, respiratory frequency, temperature, pulse and oxygen in the blood of every one of the patients. The transmitter module is responsible for sending real-time human physiological measurements to the receiver module that through communication serial communicates with the computer where the graphical interface allows to view and compare the values of each physiological measure, and to reduce the response time and diagnosis of patients. For the validation of the results obtained were compared the human physiological measures taken manually and with the prototype multimodal, obtaining result of average time of 1.23 minutes being faster than the decision in manually. It concluded that after having done the research, the prototype multimodal optimizes the time spend in the reading of the measures physiological human in cases of emergency, in real time. It is recommended to use the prototype multimodal Telemedicine, by its reading of measures physiological human in real time regardless of the distance and the environment where the patient is, providing better care of an effective and efficient manner.
