  • Sphygmogram measure method and device for two closed measured points
    Patent number: 6911009
    Abstract: A sphygmogram measure method and device includes an upstream and a downstream pressure sensor arranged in accordance with the bloodstream direction to measure the pulse pressure of two adjacent points on radial artery in the wrist. The pulse pressures are processed and converted to analog signals by an amplitude filter circuit and an adjusting circuit. The analog signal of upstream pulse pressure is converted to a digital signal, which is stored in a digital signal process unit. The signals of upstream pulse pressure and downstream pulse pressure are also transmitted as a start signal and a stop signal respectively to a counter which measures the time lag of a pulse wave passing through the two pressure sensors. The digital signal process unit uses the digital signals of upstream pulse pressure and time lag to calculate the digital signal of downstream pulse pressure.
