Embodiment Construction

[0018] Hereinafter, the hemodynamic measurement device and the hemodynamic measurement method of the present invention will be described in detail with reference to the accompanying drawings.

[0019] [Construction of Hemodynamic Measurement Device]

[0020] First, the configuration of the hemodynamic measurement device of the illustrative embodiment of the present invention will be described.

[0021] figure 1 is a block diagram of a hemodynamic measurement device in accordance with an illustrative embodiment. As shown, the hemodynamic measurement device 100 has: a PWTT measurement unit 120 , a body posture measurement unit 140 , a data calculation unit 160 , a data output unit 180 and an operation unit 190 .

[0022] The PWTT measurement unit 120 is a unit configured to measure PWTT (Pulse Wave Transit Time). The PWTT measurement unit 120 has a measurement electrode 122 , an SpO 2 probe 124 and a PWTT calculation unit 126 .

[0023] The measuring electrodes 122 are confi...

Abstract

An exemplary embodiment of a hemodynamics measurement apparatus can include a PWTT measuring unit configured to measure a pulse wave transit time, a body posture measuring unit configured to measure a body posture of a living body, and a data calculation unit configured to calculate data for measuring a hemodynamics value from the measured pulse wave transit time and body posture of the living body. Also, a hemodynamics measurement method can include measuring a pulse wave transit time and a body posture of a living body, and calculating data for measuring a hemodynamics value from the measured pulse wave transit time and body posture of the living body.

Description

technical field [0001] The present invention relates to a hemodynamic measurement device and a hemodynamic measurement method for measuring hemodynamic characteristics of a living body by measuring PWTT (pulse wave transit time) while changing a body posture. Background technique [0002] Blood pressure is measured to assess the impending risk of disease related to the arteries and heart. To improve the reliability of risk assessment, more precise measurement of blood pressure is required. As disclosed in JP3140007, a device configured to measure blood pressure of both upper and lower limbs is used. [0003] However, according to the device disclosed in JP3140007, cuffs need to be attached to the upper and lower limbs. For this reason, blood pressure measurement is troublesome. Also, the device is capable of measuring blood pressure only when the cuff is attached. For this reason, blood pressure is measured intermittently rather than continuously. [0004] Therefore, th...
