  • Patent number: 8696580
    Abstract: The disclosed is an arteriosclerosis evaluating apparatus capable of easily separating pulse wave data detected at one measurement site into an incident wave and a reflected wave and capable of easily determining and evaluating the degree of arteriosclerosis. The pulse wave transmitted through an artery is detected at one site of a living body by a pulse wave detection device, and the detected pulse wave is fitted with a fitting function by a breakdown device so that the detected pulse wave can be broken down into an incident wave and a reflected wave. The degree of arteriosclerosis is evaluated from the amplitude intensities (i.e., peak intensities) of the incident wave and the reflected wave broken down from the pulse wave.

  • Patent number: 8414500
    Abstract: An arteriosclerosis diagnostic device according to various embodiments is a simple device, resistant to an external factor, such as an error resulting from a skin surface, and capable of measuring the degree of hardness of an artery. The arteriosclerosis diagnostic device detects a heart sound and a pulse wave at least one location of a living body, the pulse wave propagating through an artery in relation to the heart sound, converts detected signals thereof into respective frequency signals, specifies the peak frequency of each of the frequency signals, and determines the degree of arteriosclerosis on the basis of the difference between the peak frequency of the heart sound and the peak frequency of the pulse wave. Accordingly, the degree of arteriosclerosis can be determined by comparison between the frequency signals.
