Embodiment Construction

[0032] As an embodiment to which the present invention is applied, an embodiment of a blood pressure measurement device that measures a subject's blood pressure using the subject's wrist as the measurement target site and the measurement target artery as the radial artery will be described. However, the form to which the present invention can be applied is of course not limited to the embodiments described below.

[0033] 1. General structure

[0034] figure 1 (1) is a configuration diagram of the blood pressure measurement system of the present embodiment. This blood pressure measurement system is configured to include an ultrasonic sphygmomanometer 1 and a cuff-type sphygmomanometer 3. The ultrasonic sphygmomanometer 1 is configured to be used by the subject wearing it on the wrist, and the cuff-type sphygmomanometer 3 is wrapped around the upper arm of the subject. department to use.

[0035] In the cuff-type sphygmomanometer 3 , a cuff for sensing blood pressure is wra...

Abstract

The invention provides a blood pressure measuring device and a blood pressure measuring method. In an ultrasonic sphygmomanometer (1), a blood vessel diameter measuring unit (110) measures a blood vessel diameter of a radial artery to be measured based on a result of receiving ultrasonic waves by an ultrasonic sensor (21). In addition, the pressurizing unit ( 30 ) applies pressure so as to compress the radial artery from the body surface. Next, a correlation equation ( 823 ) representing the relationship between the blood vessel diameter of the radial artery and the blood pressure under the pressurization by the pressurization unit ( 30 ) is obtained and stored in the storage unit ( 800 ). Next, the blood pressure calculation unit (160) controls the pressurization operation of the pressurization unit (30), and calculates the blood pressure using the blood vessel diameter measured under the pressurization and the stored data in the storage unit (800).

Description

technical field [0001] The present invention relates to devices and the like for measuring blood pressure of a subject. Background technique [0002] Conventionally, devices that measure blood flow, blood vessel diameter, and blood pressure using ultrasound or the like, and devices that measure the modulus of elasticity of blood vessels have been proposed. These devices are characterized in that they can perform measurements in a manner that does not cause pain or discomfort to the subject. [0003] For example, Patent Document 1 discloses a method of calculating blood pressure from a blood vessel elasticity index called a stiffness parameter and a blood vessel diameter assuming a nonlinear relationship between blood pressure changes and blood vessel diameter changes. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2004-41382 [0005] The technology disclosed in Patent Document 1 is a technology for calculating blood pressure based on correlation characteristics ...
