  • Patent number: 7510530
    Abstract: A pressing cuff presses a pressure sensor above an artery. The level of the pressure applied to the pressure sensor is changed while the pulse wave is measured based on information about the pressure from the pressure sensor. In order to adjust the level of the applied pressure using the pressure of gas in the pressing cuff, a three-port valve and a two-port valve are controlled so that the connection is changed to establish a state of holding the amount of the gas in the pressing cuff. Then, the state is changed to a state of isolating and discharging gas in which a part of the held gas is isolated from the remaining amount of the gas to be discharged. Then, the state is changed to the state of holding the remaining amount of gas in the pressing cuff.

  • Patent number: 7043296
    Abstract: A biosignal sensing device (2) includes an electrode section (12) including a pair of electrodes (12a,12b) mounted so that a living body can be in close proximity to or in contact with the electrodes. An oscillation section (11) supplies a high frequency signal to the electrodes. A reflected-wave level from the electrodes receiving the high frequency signal changes according to a change in impedance in the electrodes that are in close proximity to or in contact with the living body. This change in reflected-wave level reflects a change in impedance resulting from body movement of the living body such as respiration and pulsation. A sensing section (13) senses a signal indicating the change in reflected-wave level. Based on this signal, a signal amplifying section (14) calculates a desired biosignal such as pulse rate and respiration rate.
