  • Patent number: 10582861
    Abstract: The embodiment provides a blood pressure measurement device equipped with an air bag drive unit, a pressing surface formed with pressure sensors, and a control unit which calculates first blood pressure values on the basis of a first pressure pulse wave that was detected by the pressure sensors, generates calibration data using the first blood pressure values, and calculates second blood pressure values by calibrating, using the calibration data, a second pressure pulse wave that is detected by the pressure sensors in a state that the pressing force is set at an optimum pressing force. The control unit performs the processing of calculating second blood pressure values by calibrating the second pressure pulse wave if detection conditions of the second pressure pulse wave coincide with detection conditions of a pressure pulse wave used for generation of the calibration data.

  • Publication number: 20190313921
    Abstract: A measurement device includes a pulse wave signal acquisition unit, a pulse wave velocity calculator, a transfer function calculator, a phase diagram classifier, and an aneurysm determinator. The pulse wave signal acquisition unit acquires time-series pulse wave signals of each of an upper arm and an ankle of the subject. The pulse wave velocity calculator obtains a brachial-ankle pulse wave velocity based on the pulse wave signal of the upper arm and the pulse wave signal of the ankle. The transfer function calculator calculates a transfer function from the pulse wave signal of the upper arm and the pulse wave signal of the ankle. The phase diagram classifier classifies the phase diagram of each subject into any one of four groups. The aneurysm determinator determines presence or absence of the abdominal aortic aneurysm by a criterion set according to each group.

  • Publication number: 20190090759
    Abstract: A pulse wave detecting device includes a sensor section and a control unit. The sensor section is rotatable about a first axis and is rotatable about a second axis. The control unit determines a rotation angle about the second axis and a rotation angle about the first axis in a state where the sensor section is pressed against the body surface with a prescribed pressing force. After determining the optimal roll angle and the optimal pitch angle, the control unit reduces the pressing force to a reset value smaller than the prescribed pressing force and larger than zero, increases the pressing force from this state, detects a pulse wave based on pressure signals detected by pressure detecting elements during the increase, and calculates vital information based on the detected pulse wave.

  • Patent number: 10130270
    Abstract: An electronic blood pressure monitor retrieves a pulsewave signal that is superimposed on a cuff pressure signal and indicates a pulsewave at a measurement site, and acquires a string of pulsewave amplitudes indicated by the pulsewave signal. A first envelope connects the amplitudes created for the acquired string of pulsewave amplitudes. Local maxima and minima in the first envelope are detected. With respect to the strings of amplitudes corresponding respectively to the local maxima and minima, a local-maximum envelope and a local-minimum envelope connecting the amplitudes are created. Two pressure values at points at which portions on the high-pressure-side and low-pressure-side with respect to the maximum peaks of the local-maximum envelope and the local-minimum envelope respectively cross first and second threshold levels are obtained, and the average values of each pair of pressure values are calculated as the systolic blood pressure and the diastolic blood pressure respectively.
