With soaring of the sub-health population around the world, the traditional medical treatment has not met the increasing demand; it is urgent to create a modern nursing technology to provide service for human being. With development of the sensor technology and continuous improvement of the wireless communication technology, the new medical monitoring system has been gradually released from the traditional human-labor nursing. On the basis of development of the intra-body communication technology, a wireless, wound-free, portable medical system with real-time monitoring is proposed in this paper. In combination with the remote diagnosis system in the modern medical treatment, the sensor technology and the intra-body communication technology can be utilized to provide all-sided and real-time monitoring for individuals. Because data fusion can be effectively implemented between the systems and WAN & LAN, the model of the medical monitoring system for families is also presented in this paper, which offers guidance for further promotion of real-time medical monitoring. © 2005 - 2013 JATIT & LLS.
