  • Publication number: 20160256085
    Abstract: The present invention relates to a blood glucose management device capable of generating valid blood glucose data and an operation method therefor, the device compelling the input of state information (e.g., an empty stomach and time information such as two hours postprandial) at the time of blood glucose measurement by a measurer for the acquisition of accurate blood glucose data. The blood glucose management method may comprise the steps of: sensing the connection of a blood glucose meter; outputting to a display unit a state information input window for inputting state information at the time of blood glucose measurement if the connection of the blood glucose meter is sensed; and controlling the blood glucose meter to measure blood glucose if the state information is input.
