Embodiment Construction

[0027] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. figure 1 is a schematic diagram showing a circuit of an arteriosclerosis inspection apparatus 10 to which the present invention is applied.

[0028] exist figure 1 In, reference numeral 12 represents an inflatable wristband, which comprises a belt-shaped cloth bag and a rubber bag accommodated in the cloth bag, and this wristband is suitable for wrapping around an upper part 14 of a patient as a living recipient around. Wristband 12 is connected to pressure sensor 16 and pressure control valve 18 by a tube 20 . The pressure control valve 18 is connected to an air pump 24 through a pipe 22 . The pressure control valve 18 adjusts the pressure of pressurized air supplied from the air pump 24 and supplies the pressure-regulated air to the cuff 12 or discharges the pressurized air from the cuff 12 to control the air pressure in the cuff 12 .

Abstract

An apparatus (10) for inspecting arteriosclerosis of a living subject, comprising a pulse-wave detecting device (54) which detects a pulse wave from a portion (38) of the subject; an augmentation-index determining means (96) for determining, based on the pulse wave detected by the pulse-wave detecting device, an augmentation index indicating a proportion of a reflected-wave component of the pulse wave to an incident-wave component thereof, so that the arteriosclerosis of the subject is inspected based on the augmentation index determined by the augmentation-index determining means; at least one waveform-related-information obtaining device (28, 86; 68, 88; 54, 90; 70, 92; 72, 94) which obtains at least one sort of waveform-related information that is related to a change of a waveform of the pulse wave detected by the pulse-wave detecting device; a display device (79); an augmentation-index displaying means (98) for operating the display device to display the augmentation index determined by the augmentation-index determining means; and a waveform-related-information displaying means (100) for operating the display device to display, in addition to the augmentation index, the waveform-related information obtained by the waveform-related-information obtaining device.

Description

technical field [0001] The present invention relates to an arteriosclerosis examination apparatus for examining arteriosclerosis of a living recipient based on an increasing index. Background technique [0002] Because the pulse wave propagating in the blood vessel is reflected at the bifurcated or narrowed part of the blood vessel, the waveform of the detected pulse wave includes an incident wave component and a reflected wave component. The incident wave component is when blood is ejected from the recipient's heart and Produced when propagating towards the peripheral portion of the recipient, reflected wave separation occurs when the incident wave is reflected. The pulse wave increase index is generally called AI, which represents the ratio of the reflected wave component of the pulse wave to its incident wave component. Usually the increase index AI is determined as a percentage of a value obtained by dividing the detected pulse pressure of the pulse wave by subtracting ...
