Web based patient health monitoring system using Raspberry Pi

Continuous Physiological parameter monitoring is essential for elderly and ill patients. There is a need for a Web-based Patient health monitoring system, when the patient is not in the Hospital. Such a system will enable the doctors to monitor the physiological parameters online and take necessary action in emergency. In this paper, a prototype of basic physiological parameter monitoring system based on Arduino and Raspberry Pi microcontroller boards is implemented. Various basic physiological parameters such as blood pressure, heartbeat, oxygen saturation in Blood (SPO2), body temperature and fall detection are measured using relevant sensors and sent to the Arduino microcontroller board for further processing. The computed parameters are then sent to a Raspberry Pi based Web server for display on the web page. ZigBee is used for communication between Arduino and Raspberry Pi. The necessary software is developed using Arduino IDE and Python language. The measured physiological parameters are updated every 60 seconds. The updated parameter values can be viewed from anywhere using an internet enabled device. Also, when the value of the physiological parameters exceeds certain threshold, the caretaker is alerted through SMS. This system is especially helpful for elderly and ill patients.
