Abstract: PURPOSE: A blood pressure measurable watch phone and a method of using the watch phone are provided to take a necessary measure to an emergency situation by periodically checking a blood pressure and transmitting a numerical value of the checked blood pressure to a hospital without a necessity of a patient's visiting the hospital. CONSTITUTION: A blood pressure is measured with an arm band, a pressure sensor, and an oscillator installed in a watch phone(S101). A previously stored numerical value of a blood pressure indicating a dangerous state and a real-time measured numerical value of blood pressure are compared to recognize an emergency state of a patient(S102). If the currently measured blood pressure is greater than the dangerous numerical value of the blood pressure requiring a hospital's aid, the data related to the measured blood pressure of the patient is transmitted to a hospital(S104). If the patient is considered not to be risky, the data related to the blood pressure is continuously stored(S103), which is periodically transmitted to the hospital through a wireless communication network by a pre-set period(S105). Accordingly, the state of the patient is accurately determined on the basis of the transmitted blood pressure data and a step is taken suitably(S106).
