Problems solved by technology

In addition, in the method of Non-Patent Document 1, the blood vessel diameter is measured in units of 0.1 mm, and the diameter of the upper arm artery is about 3 mm, and the error becomes about 3%, which is a very large value.
That is, the measurement accuracy is low

Embodiment Construction

[0044] Next, an embodiment of the vascular endothelial response measuring device of the present invention will be described.

[0045] figure 1 It is a block diagram schematically showing the configuration of the vascular endothelial response measuring device 1 . The vascular endothelial reaction measurement device 1 includes a blood expelling unit 2 , a control unit 3 , and a measurement unit 4 . The blood expelling unit 2 is, for example, a cuff (compression belt) utilizing air pressure, and is attached to the arm of the subject. Under the control of the control unit 3, air is introduced into the cuff to compress the arteries of the arm to expel blood. In addition, based on the control of the control unit 3 , the air introduced into the cuff is released to cancel the exsanguination. In the vascular endothelial reaction measuring device, since the shape characteristic of the blood vessel wall after the blood absorptives is released is measured, it is preferable to quickly ...

Abstract

A blood vessel endothelium reaction measuring instrument comprises an avascularizing section (2) for avascularize an arterial vessel of an organism, a measuring section (4) for measuring the shape characteristic of the arterial vessel or the vessel wall, and a control section (3) for controlling the avascularizing section to repeat avascularization and its cancellation of the arterial vessel periodically two or more times. The measuring section (4) measures the shape characteristic during at least a part of the period for which the avascularization of the arterial vessel is canceled and processes the data on the shape characteristic during the part of the period using the cycle of the avascularization and its cancellation.

Description

technical field [0001] The invention relates to a blood vessel endothelial reaction measuring device and a control method thereof for functional inspection of arterial blood vessel wall tissue. Background technique [0002] In recent years, the number of people suffering from circulatory diseases such as myocardial infarction and cerebral infarction has gradually increased, and the prevention and treatment of such diseases have become a major issue. [0003] Arteriosclerosis is closely related to the pathogenesis of myocardial infarction or cerebral infarction. Specifically, if atherosclerosis forms on the arterial wall, or arteries no longer produce new cells due to various factors such as high blood pressure, the arteries lose their elasticity and become hard and brittle. Then, at the site where the atherosclerosis has been formed, the blood vessel is occluded, or the vascular tissue covering the atheroma is ruptured to cause the atheroma to flow out into the blood vessel...
