  • Patent number: 11058343
    Abstract: When a user uses a finger to press and hold a first candidate display area, the first candidate display area is enclosed in a selection frame (W1), a simple window (W10) is displayed, and analysis results relating to a first candidate segment waveform are displayed in this simple window (W10). Analysis results can therefore be confirmed without switching screens and, as a result, inspection results can be confirmed with fewer steps and an electrocardiographic waveform and analysis results therefor can be compared on the same screen.

  • Patent number: 7566307
    Abstract: A blood pressure monitoring apparatus which continuously estimates and monitors the blood pressure by using the pulse wave propagation time can accurately estimate the blood pressure. While an estimated blood pressure is continuously calculated by using the pulse wave propagation time, the correlation between the pulse wave propagation time and the interval between feature points contained in two consecutive heart beat waveforms of an electrocardiogram is monitored. If the correlation is reversed, the blood pressure is actually measured, and the estimated blood pressure is corrected on the basis of the difference between the estimated blood pressure and actually measured blood pressure.

  • Patent number: 7393327
    Abstract: In blood pressure monitoring apparatus which continuously estimates and monitors blood pressure by using the pulse wave propagation time, blood pressure fluctuation can be accurately estimated. If both blood pressure estimated from the pulse wave propagation time and a waveform parameter obtained from the accelerated pulse wave have abnormal values, it is determined that the blood pressure is truly fluctuating, and blood pressure measurement by another method, e.g., blood pressure measurement using a cuff is performed.

  • Patent number: 6999813
    Abstract: To disclose a biomedical signal processor with a simple configuration and a minimum space capable of confirming an operating condition and a signal collection state of the biomedical signal processor such as an electrocardiograph. As an example of the biomedical signal processor according to the present invention, a Holter electrocardiograph supplies biomedical signals to a light-emitting element (LED) 30 and applies a bias supply voltage from a power supply section 80 to the LED 30. By setting a bias voltage to a voltage so that a level of a minimum supply voltage to the LED 30 becomes a positive potential when electrocardiogram signals are input to an input amplification section 10, the LED 30 turns OFF when power is turned OFF, becomes half-lit when power is turned ON and its luminescence intensity is variable when signals are collected normally, making it possible to easily check a state of the apparatus.
