REAL-TIME BLOOD PRESSURE MEASUREMENT DEVICE USING TWO SENSORS AND REAL-TIME BLOOD PRESSURE MEASUREMENT METHOD USING THE SAME

摘要

The present invention relates to a real-time blood pressure measuring device using two sensors and a real-time blood pressure measuring method using the same, and more particularly, to a real-time blood pressure measuring device using two sensors, comprising two PPG sensors, and the two PPG sensors. a PPG sensor unit that detects two PPG (photo-plethysmography) signals from the sensor on the user's wrist; a storage unit for storing a user's usual blood pressure value for real-time blood pressure measurement; and a blood pressure estimation algorithm for measuring blood pressure, and based on the two PPG signals measured by the PPG sensor unit and the user's usual blood pressure value stored in the storage unit through the execution of the blood pressure estimation algorithm, the user's lowest blood pressure and It is characterized in that it includes a blood pressure measurement control unit for estimating the maximum blood pressure. According to the real-time blood pressure measurement device using two sensors and the real-time blood pressure measurement method using the two sensors proposed in the present invention, a PPG sensor unit for detecting two PPG signals from the two PPG sensors at a user's wrist, and real-time blood pressure measurement It is equipped with a storage unit that stores the user's usual blood pressure value for By including a blood pressure measurement control unit for estimating the user's diastolic blood pressure and maximum blood pressure based on the blood pressure value, the existing sensor-type blood pressure measuring device provides two functions without the inconvenience of inputting additional ECG measurement values and personal body information. It is possible to estimate and measure a blood pressure value without error using only the PPG sensor and the user's initial blood pressure value serving as a reference. In addition, according to the real-time blood pressure measuring device using two sensors and the real-time blood pressure measuring method using the two sensors of the present invention, it is possible to measure blood pressure while a user wears a wrist watch-type device having two PPG sensors built-in on his/her wrist. In this configuration, it is possible to estimate the blood pressure without error using only two PPG sensors and the first blood pressure value, thereby reducing the error of the wrist-type blood pressure monitor. Convenience and efficiency of use according to real-time blood pressure measurement may be further improved.
