Wireless sensor network for medical applications

الملخص EN

This work presents a healthcare monitoring system that can be used in an intensive care room.

Biological information represented by ECG signals is achieved by ECG acquisition part .

AD620 Instrumentation Amplifier selected due to its low current noise.

The ECG signals of patients in the intensive care room are measured through wireless nodes.

A base node is connected to the nursing room computer via a USB port , and is programmed with a specific firmware.

The ECG signals are transferred wirelessly to the base node using nRF24L01+ wireless module.

So, the nurse staff has a real time information for each patient available in the intensive care room.

A star Wireless Sensor Network is designed for collecting ECG signals .

ATmega328 MCU in the Arduino Uno board used for this purpose.

Internet for things used For transferring ECG signals to the remote doctor, a Virtual Privet Network is established to connect the nursing room computer and the doctor computer .

So, the patients information kept secure.

Although the constructed network is tested for ECG monitoring, but it can be used to monitor any other signals.
