Um sistema de monitoramento remoto de pacientes usando rede sem fio

Abstract

This Work implements a remote system to monitor medical patients by using Internet communication through TCP/IP protocol and wireless network. The main application is in the biomedical area where the patient can have some physiological data monitored 24 hours per day or send it to his doctor in an emergency situation. The system was developed using a circuit already done that measure ECG data. It was modified to support wireless network using a Device Driver. Two applications runs in the top of the TCP/IP stack were developed and adapted to monitor patients in different ways. The project implementation considered some issues like cost, energy management and fault tolerance.The main project challenges were the Device Driver implementation and the circuit modification to support wireless network. The biggest difficulties were the software implementation considering the poor 8-bit microcontroller resources and project adaptation from the circuit already existed. Some practical project applications were tested and proved that it is not limited to be used only in the medical area but also in others that needed communication using wireless network.
