Embodiment Construction

[0033] figure 1 It is a diagram showing a configuration example of the blood pressure measurement device in this embodiment.

[0034] The blood pressure measurement device 2 is a system for measuring biological information by irradiating ultrasonic waves to blood vessels to be measured and analyzing reflected waves from the blood vessels. In the present embodiment, a configuration in which blood vessel diameter and blood pressure are measured as biological information has been described, but a configuration in which other biological information is measured may also be used.

[0035] The blood pressure measurement device 2 of this embodiment includes: an ultrasonic probe 6 that is constantly attached to the measurement site of the subject 3 (in this embodiment, the blood vessel to be measured: the carotid artery 5 ), and a blood pressure probe 6 for calibration. Meter 8, and measurement control device 10.

[0036] The ultrasonic probe 6 transmits ultrasonic waves and receives...

Abstract

Measurement data of a blood vessel is generated based on a measurement result of the blood vessel obtained by a blood vessel diameter measurement unit, and a breathing period estimating section estimates a breathing period corresponding to a breathing cycle based on the measurement data. A blood pressure calculating section calculates blood pressure relevant to the blood vessel based on the measurement data. An average calculating section calculates the average of the blood pressure calculated by the blood pressure calculating section in the breathing period estimated by the breathing period estimating section.

Description

[0001] This application is based on the benefit of priority of Japanese Patent Application No. 2014-186041 filed on September 12, 2014, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a blood pressure measuring device and a blood pressure measuring method. Background technique [0003] Blood pressure is one of the important parameters to grasp a person's physical condition, and blood pressure measurement at the medical site is one of the indispensable elements. With regard to blood pressure measurement methods, various techniques have been disclosed so far. For example, there is a technique (for example, see Patent Document 1): an ultrasonic probe is attached to the skin surface of a blood vessel, the vessel diameter is obtained from the reflected wave of the ultrasonic wave, and the blood pressure is measured based on the relational formula of the blood vessel diameter. In addition, the technique ...
