Embodiment Construction

[0024] Hereinafter, an example of a preferred embodiment to which the present invention is applied will be described with reference to the drawings. In the present embodiment, the blood vessel diameter is described as the blood vessel cross-sectional index value, but the blood vessel cross-sectional area may be used instead of the blood vessel diameter (in this case, "blood vessel diameter" in the following text is replaced with "vessel cross-sectional area" Just understand). The form in which the present invention can be applied is obviously not limited to the embodiments described below.

[0025] 1. Principle

[0026] In this embodiment, a blood pressure measurement device (central blood pressure measurement device) for measuring central blood pressure is determined by specifying parameters related to blood pressure estimation processing for estimating central blood pressure (hereinafter referred to as "parameters for estimating central blood pressure"). Make corrections. ...

Abstract

In an ultrasonic blood pressure meter 1, changes in blood pressure in a peripheral artery measured by a blood pressure meter 2 are input from an input unit 40. A blood vessel diameter measuring unit 120 measures changes in the blood vessel diameter of a central artery using ultrasound. A calibrating unit 130 calibrates a parameter related to a blood pressure estimation process for estimating central blood pressure from the blood vessel diameter of the central artery, using results of measurement by the blood pressure meter 2 and the blood vessel diameter measuring unit 120 during a given correspondence period, of a one-heartbeat period, in which the relationship between the blood vessel diameter of the central artery and the blood pressure in the peripheral artery corresponds to the relationship between the blood vessel diameter of the central artery and the central blood pressure.

Description

technical field [0001] The present invention relates to a blood pressure measurement device and the like for measuring central blood pressure. Background technique [0002] Conventionally, devices that measure blood flow, blood vessel diameter, and blood pressure using ultrasonic waves, and devices that measure the modulus of elasticity of blood vessels have been developed. These devices are characterized in that they can perform non-invasive measurements that do not cause pain or discomfort to the subject. [0003] For example, Patent Document 1 discloses a method of capturing the relationship between blood vessel diameter change or blood vessel cross-sectional area change and blood pressure change as a nonlinear relationship, and estimating blood pressure from a stiffness parameter representing blood vessel hardness and blood vessel diameter or blood vessel cross-sectional area. [0004] [Patent Document 1] Japanese Patent Laid-Open No. 2004-41382 [0005] In addition, c...
