The health care is in increasingly high demand with the aging population. In this paper, we present a novel health care platform for elderly people and patients who need to be taken care. The platform consists of a walk-aid unit, medical apparatus for health monitoring, data storage unit and remote monitoring unit. The medical devices are used for the elderly or patients who are undergoing a rehabilitative treatment, to determine the body's vital physiological indexes like pulse rate, heart rate, blood pressure level, body temperature and the inertial navigation system (INS). The inertial navigation system (INS) is employed to capture people's abnormal action like tumble. The walk-aid platform is designed to enhance people's mobility and collect position information of the elderly in case of an emergency. It is also equipped with a camera to capture a picture of the elderly and the environment. The data storage unit can collect and store the data from the medical devices and the walk-aid unit. The remote monitoring unit like pad or smart phone can be connected with the platform to check the situation of users. And in turn, if an emergency situation happened, the server computer can also send a message to the mobile device. The case study shows that it is an efficient way to keep the user under observation.
