  • Patent number: 9265421
    Abstract: A medical monitoring system includes: a plurality of biological information displaying devices connected to a network; and a portable terminal which can wirelessly communicate with the biological information displaying devices. The plurality of biological information displaying devices includes a first device and a second device. When a value of biological information is larger or smaller than a preset threshold, the first device transmits alarm information. In case where the first device transmits the alarm information, a receiving unit of the portable terminal receives the alarm information, and a transmitting unit of the portable terminal wirelessly transmits the received alarm information to the second device, and the second device receives the biological information through the network and the biological information is displayed on the second device.

  • Patent number: 6129677
    Abstract: An apparatus for non-invasion heart monitoring includes electrocardiogram measuring means (1) for measuring electrocardiograms, pulse wave measuring means (2) for measuring pulse waves, and a CPU (30) for processing electrocardiogram signals derived from the electrocardiogram measuring means (1) and pulse wave signals derived from the pulse-wave measuring means (2). The CPU (30) detects the amplitudes of the pulse waves corresponding to the R waves of the cardiogram and the pulse wave propagation times, and computes a ratio (Nr/N) of the heart rate N and the heart rate Nr exclusive of the heart beats of wave deficits.

  • Patent number: 6083171
    Abstract: A pulse wave propagation time is counted constantly. Not only it is judged whether or not a pulse wave propagation time change .DELTA.T exceeds a pulse wave propagation time change threshold .DELTA.Ts, but also it is judged whether or not cardiovascular dynamic changes .DELTA.HR, r.sub.1, r.sub.2 exceed thresholds thereof .DELTA.HRs, r.sub.1 s, r.sub.2 s, whereby a sudden turn for the worse in the blood pressure fluctuation of a subject is monitored. If any one of the changes exceeds the threshold thereof, a blood pressure measurement using a cuff 2 is made on the subject.

  • Patent number: 5876348
    Abstract: During a noninvasive blood pressure measurement using a cuff 2, a pulse wave propagation time T1 from the appearance of the peak value of an R wave in an electrocardiogram (ECG) waveform to the appearance of the bottom value of a pulse wave is counted, and a blood pressure value BP1 is calculated from a count result T1 and parameters .alpha., .beta. specific to a subject obtained during a pulse wave propagation time calibration. Then, the absolute value of a difference between the blood pressure value BP1 and a blood pressure value NIBP1 obtained by the noninvasive blood pressure measurement using the cuff 2 is calculated, and it is indeed whether or not the calculated absolute value is within a predetermined threshold.sub.-- BP. If the absolute value is judged to exceed the threshold.sub.-- BP, then blood pressure is measured again noninvasively using the cuff 2, and a blood pressure value NIBP1'obtained from such repeated measurement is displayed on a display 22.

  • Patent number: 5755669
    Abstract: After an initial blood pressure measurement using a cuff 2 has been made, not only a pulse wave propagation time Tt is counted consecutively, but also a pulse wave propagation time change .DELTA.T is calculated every time the pulse wave propagation time Tt is counted and compared with a pulse wave propagation change threshold .DELTA.Ts. When the pulse wave propagation time change .DELTA.T exceeds the pulse wave propagation time change threshold .DELTA.Ts, not only a blood pressure value BPt is measured with the cuff 2, but also a pulse wave propagation time Tt.sub.1 is counted. If there are at least two sets of data, each set of data consisting of a blood pressure value BPt and a pulse wave propagation time Tt.sub.1, coefficients .alpha., .beta. specific to a subject are calculated from such two sets of data by a least-squares method. Then, the pulse wave propagation time change threshold .DELTA.Ts is calculated from the coefficient .alpha., and the current pulse wave propagation time change threshold .DELTA.
