    • An array-type capacitive pressure pulse wave sensor includes m rows of lower electrodes arranged in parallel with each other to extend substantially linearly in a direction approximately orthogonal to the extending direction of the artery at the time of measurement, n columns of upper electrodes arranged in parallel with each other at a prescribed distance from the m lower electrodes to extend in a direction crossing the extending direction of the m lower electrodes, and m×n capacitive elements formed at intersections of the m lower electrodes and the n upper electrodes. The m×n capacitive elements are arranged in a staggered manner when the pressure detecting portion is seen in two dimensions. Thus, it is possible to provide an array-type capacitive pressure pulse wave sensor that can be manufactured inexpensively and that ensures accurate and stable measurement of the pressure pulse wave.
    • 阵列型电容式压力脉搏波传感器包括相互平行布置的m列下电极,以在测量时与动脉的延伸方向大致正交的方向基本上线性地延伸,上列电极排列成n列 在与m个下部电极的规定距离处彼此平行,并且在与m个下部电极的延伸方向交叉的方向上延伸,以及在m个下部电极和n个上部电极的交叉处形成的电容元件。 当在两个维度上看到压力检测部分时,mxn电容元件以交错的方式布置。 因此,能够提供廉价制造的阵列型电容式压力脉搏波传感器,能够确保压力脉搏波的精确,稳定的测量。

    • A pulse wave measuring apparatus is disclosed, in which a sensor unit can be fixed easily under an appropriate pressure at an appropriate position on a living organism. With the living organism fixed by a living organism fixing device, a pressure sensitive portion arranged on the sensor unit is pressed against the living organism thereby to measure the pulse wave. The living organism fixing device includes a fixing stand for fixing the living organism in position, and fastening bands for connecting the fixing stand and the sensor unit and fastening the living organism fixedly to the fixing stand while at the same time activating by pressing the sensor unit against the living organism. The fastening bands include a first band portion with one end mounted on the sensor unit and the other end mounted on the fixing stand and a second band portion with one end mounted on the sensor unit and the other end removably mounted on the fixing stand. The fixing stand has a constant force spring for pulling the other end of the first band portion with a constant force.

    • 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.
    • 按压袖带将压力传感器压在动脉上方。 基于来自压力传感器的压力的信息来测量施加到压力传感器的压力的水平,同时测量脉搏波。 为了使用压力套筒内的气体压力来调节施加的压力水平,控制三通阀和双口阀,使得连接被改变以建立保持气体量的状态 在压紧的袖口。 然后,将状态改变为将一部分保持气体与要排出的气体的剩余量隔离的气体的隔离和排出状态。 然后,将状态改变为保持按压套筒中的剩余量的气体的状态。
