More Information
Summary:The present invention relates to a blood pressure measuring using multiple biological signals which comprises: a sensor module that measures an ECG signal and a PPG signal from the body of a user; and a processor for calculating blood pressure of the user based on PTT calculated from the ECG signal and the PTT signal provided from the sensor module. The processor is configured to adaptively modify a threshold value in response to a measurement result of a previous unit time in detecting a peak having an amplitude higher than the threshold value from the ECG signal and the PPG signal. 본 발명은 다중 생체신호를 이용한 혈압 측정 장치에 관한 것으로, 사용자의 신체로부터 ECG 신호와 PPG 신호를 측정하는 센서 모듈, 및 센서 모듈로부터 제공되는 ECG 신호와 PPG 신호로부터 산출되는 PTT에 기반하여 상기 사용자의 혈압을 산출하는 프로세서를 포함하며, 프로세서는 ECG 신호와 PPG 신호로부터 임계치보다 높은 진폭을 갖는 피크를 검출함에 있어서 이전 단위 시간의 측정 결과에 대응하여 적응적으로 상기 임계치를 수정하도록 구성된다.
