Embodiment Construction

[0017] Arterial flow mediates vasodilation

[0018] Human blood vessels are subject to external stimuli to change the function of adjusting blood flow. This self-adjusting function can make blood vessels change with different environments. When arterial blood vessels are stimulated physiologically or chemically, similar to blood vessels being blocked, resulting in insufficient blood flow, or ischemic conditions, arterial endothelial cells will adjust blood flow in their own way to make changes, which is called arterial blood flow mediated blood vessels Diastolic function is mainly caused by the release of nitric oxide by arterial endothelial cells. If the arterial endothelial function is abnormal, sufficient nitric oxide cannot be released, so the vasodilation function mediated by arterial blood flow is not good.

[0019] The technical contents and features of the present invention will be described in detail below through the enumerated embodiments in conjunction with the acc...

Abstract

A method for assessing the arterial blood flow-mediated vasodilatation function by an air bag arm band comprises the following steps of providing a processing unit; taking a digital air bag arm band device, an air bag arm band, a pressure sensor and a flow sensor being arranged in the device which is provided with a sphygmomanometer function; measuring the state of the brachial artery before the blood clotting by the digital airbag arm band device, and obtaining a first vibration wave from the pressure sensor sent to the processing unit; and using the digital air bag arm band device to perform blood clotting, measuring a brachial artery condition by the digital air bag arm band device, and obtaining and sending a second vibration wave to the processing unit by the pressure sensor; and converting the first vibration wave and the second vibration wave into a first arterial volume change amount wave and a second artery volume change amount wave through a transfer function constructed by the pressure sensor and a flow sensor, and comparing each parts of the two volumetric waves, and outputting the specific value of the difference.

Description

technical field [0001] The invention is related to the measurement of arterial endothelial cell dysfunction, in particular to a method for evaluating arterial blood flow mediated vasodilation function with an airbag armband. Background technique [0002] Atherosclerosis is the cause of harm to human health. Due to the growth of connective tissue and the deposition of substances such as cholesterol on the arterial wall, the arterial wall becomes hard and thick, resulting in the narrowing of the inner diameter of the artery and the loss of elasticity of the entire artery. . Generally speaking, the etiology of atherosclerosis is related to endothelial cell dysfunction, and vascular endothelial function can be evaluated through the response of arterial blood flow mediated vasodilation. [0003] The main cause of coronary artery disease is atherosclerosis, which is caused by risk factors such as cardiovascular disease, old age, smoking, hypercholesterolemia, diabetes, and high b...
