A method for continuously detecting body physiological information trajectories through the use of a personal wearable device. Through short-distance wireless transmission, a smartphone or a computer first transmits basic information, including a personal ID of a user of the device, a device ID, an ID of the smartphone or the computer, and communication links, to a remote medical data center. In this case, the device continuously detects body physiological information which can be transmitted to the remote medical data center. Corrective body physiological information data of the user is measured and transmitted to the remote medical data center. The remote medical data center processes the data and periodic pulse volume curves. The remote medical data center then transmits the numeral data converted from periodic pulse volume curves back to the personal wearable device and continuously constructs a periodic trajectory of detected personal body physiological information.
