Neck and brain arterial pulse wave speed measurement system

Abstract

The invention relates to a neck and brain arterial pulse wave speed measurement system, which is characterized by comprising a signal collection device, a signal processing device, a display device and a communication interface module, wherein the signal collection device is connected with the signal processing device through the communication interface module, the output end of the signal processing device is connected with the display device, the signal collection device is used for synchronously sampling blood flow signals at the tail sections of a common carotid artery and an internal carotid artery and converting the blood flow signals to corresponding digital signals, the signal processing device is used for processing synchronously obtained brain blood flow signals to obtain time difference among the signals, and the display device is used for displaying parameters of the blood flow signals and parameters of the time difference among the signals. The neck and brain arterial pulse wave speed measurement system achieves noninvasive detection on neck-brain arterial pulse wave speed, is accurate and reliable in results and strong in clinical practicality, reflects stiffness conditions of the cerebral artery more accurately and directly, estimates apoplexy risks, and is beneficial to early discovery and precaution of apoplexy.

Description

technical field [0001] The invention relates to a carotid and cerebral artery pulse wave velocity measurement system, a cerebral blood flow signal acquisition method and medical application thereof. It belongs to the field of medical equipment. Background technique [0002] Pulse wave refers to the pulse in the arterial system caused by rhythmic cardiac ejection and propagates from the heart to the periphery along the vascular tree. Pulse wave velocity (PWV) refers to the speed at which the arterial pulse wave is transmitted from the proximal end to the distal end. It can comprehensively reflect the damage to blood vessels caused by various risk factors and is an independent measure of the risk rate of cardiovascular diseases predictor. In the process of propagating along the vascular system to the periphery, the attenuation of pulse wave velocity and amplitude is affected by the structure of the vascular wall and the geometry of the vascular system, and its speed and shap...

Problems solved by technology

The operation is complicated and difficult to carry out, and the carotid-cerebral arteriosclerosis is also only speculative

[0009] In view of the fact that atherosclerosis of the carotid and intracranial arteries is the main cause of cerebrovascular diseases, the above prior art methods mainly detect systemic arteriosclerosis, are not very specific, and cannot directly evaluate carotid-cerebral arteriosclerosis , and the sclerosis of carotid and cerebral arteries is closely related to cerebrovascular diseases, so the existing methods cannot meet the clinical needs of cerebrovascular disease diagnosis and treatment
