  • Publication number: 20050148831
    Abstract: A patient terminal can communicate with doctor terminals and a center terminal via a communication network. The patient terminal acquires vital data from a measuring device with a receiving unit. A control unit determines whether the vital data contains an abnormal value and the necessity of messaging depending on the presence or absence of a manual messaging request with a message button and selects the doctor terminal or the center terminal. When it is determined that messaging is necessary, the control unit makes a communication unit call the selected terminal.
