Development of a physiological monitoring system for using smart carrier

With the growth of aging population and the patients with spinal cord injury, the demand of intelligent vehicle that is also called smart carrier increases. The development of a smart carrier to help the subject to stand and move becomes very important issue for home health care problem. However, the safety of user is crucial for our proposed smart carrier. The purpose of this study is to design a system based on our developed smart carrier to monitor the user's physiological conditions, including ECG, respiratory rate, and blood pressure. Using the wireless techniques, Bluetooth, into, a real-time remote healthcare and early warning system can be built. This system can be divided into two parts. The first part is composed of portable sensors that acquired physiological signals and pre-processed by micro-controller and transmitted to the monitoring system via Bluetooth. The second part includes signal display, storage and data analysis. Furthermore, while unusual physiological signal is detected, the system could send a warning signal to remind, or inform the caregivers through the personal handy-phone system (PHS) immediately and made carrier doing relative actions like emergency stop. The purposed system has the potential to be a useful monitoring and warning tool for the patients using smart carrier.
