Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals are assigned to the same components and structural elements. The names and functions of these components and structural elements are also the same.

[0042]

[0043] As an index for judging the degree of arteriosclerosis, pulse wave velocity (hereinafter referred to as PWV: Pulse Wave Velocity) is exemplified. The PWV is calculated by dividing the difference in the conduction path of the ejection wave and the reflected wave to the measurement site by the difference in the appearance time of the ejection wave and the reflected wave at the measurement site.

[0044] Using the existing PWV calculation method, the distance (2L_da) obtained by multiplying the distance (L_da) from the beginning of the aorta to the branch of the iliac artery by 2 is assumed to be that the ejection wave and the reflected wave travel fro...

Abstract

In the present disclosures, the CPU (40) of a sphygmomanometer (1) calculates blood pressure from the changes in the internal pressure of an air sac (13B) that is for measurement. Also, AI and Tr are calculated from the pulse waveform. The path difference calculation unit (405) of the CPU (40) records a correction formula for correcting a pre-recorded pulse wave propagation distance, and by substituting the calculated blood pressure values, AI, or the like into the correction formula, corrects the pre-recorded pulse wave propagation distance to approach the actual pulse wave propagation distance. A PWV calculation unit (406) calculates the PWV using said distance.

Description

technical field [0001] The present invention relates to a blood pressure information measuring device and a calculation method for calculating an index of arteriosclerosis by using the device, in particular to a blood pressure information measuring device for measuring blood pressure information effective in judging the degree of arteriosclerosis and using the device to calculate the degree of arteriosclerosis The calculation method of the indicator. Background technique [0002] In the past, as a device for judging the degree of arteriosclerosis, for example, Japanese Patent Application Laid-Open No. 2000-316821 (Patent Document 1 below) discloses a method for investigating the velocity of pulse wave propagation (hereinafter referred to as PWV: Pulse Wave Velocity) emitted from the heart. )s installation. [0003] By wearing a cuff for measuring pulse wave at least two places such as the upper arm and lower extremity, and measuring the pulse wave at the same time, based on...
