Implementation of Wireless Body Area Network Based Patient Monitoring System

Abstract

WBAN has gained considerable attention and became an emerging technology at health services due to its wide range of utilities and important role to improve the human health. The proposed system consists of different components, Pulse rate sensor which uses the optical technology to detect the flow of blood. Temperature sensor is used to measure the temperature from the body. Peripheral hemoglobin oxygen saturation (SpO2), blood pressure and electrocardiogram (ECG) are measured by the nurses. Radio Frequency Identification (RFID) reader with passive tags is used to identify the patient. Arduino UNO microcontroller is used for data processing. The patient parameters are transmitted via Bluetooth technology to the base station. The base station which is Raspberry Pi (RPi) B model 3 used to receive the collected data and acts as the web server, so the physician accesses RPi to display different information. The obtained results from different cases prove the high performance of the system and sensor nodes that are designed. The overall system operates within different environments conditions. If one sensor node is fall down, the other nodes are still operate and do not affect. Also we improve the speed of the system response. The usage of wireless communication to send the data instead of the wired one as it provides a greater mobility to the device. The cost is also minimized by utilizing the feature of sending multiple parameters via a single node.
