System for measuring conduction time of pulse waves between cerebral arteries and cerebral veins

Abstract

The invention relates to a system for measuring the conduction time of pulse waves between cerebral arteries and cerebral veins. The system comprises a signal acquisition device, a signal processing device and a display device, wherein the signal acquisition device is connected with the signal processing device through a communication interface module; and the output end of the signal processing device is connected with the display device. The cerebral blood flow signal acquisition method comprises the following steps: 1) arranging a fixed probe device with two cerebral blood flow signal acquisition devices; 2) synchronously acquiring cerebral blood flow signals; and 3) exchanging the positions of the two cerebral blood flow signal acquisition devices. The medicinal uses of the system are as follows: 1) synchronously acquiring the cerebral blood flow signals of ipsilateral encephalic large arteries (aorta) and encephalic deep veins of a person to be tested at a resting state; and 2) measuring the time difference of the two cerebral blood flow signals. Through the system provided by the invention, noninvasive detection is realized on the conduction time of pulse waves between the cerebral arteries and the cerebral veins; and the clinical practicality is strong, the stiffness of cerebral arteriolae can be accurately and directly reflected, and the risk of apoplexy is estimated, thus being beneficial for early discovering and preventing cerebral arteriosclerosis of patients.

Description

technical field [0001] The invention relates to a pulse wave transit time measurement system between brain arteries and veins, which is suitable for collecting cerebral blood flow signals and clinical treatment. It belongs to the field of medical equipment. Background technique [0002] In the pathogenesis of cerebrovascular diseases, arteriolar sclerosis is one of the important mechanisms. Clinically, it often manifests as lacunar infarction, leukoaraiosis, cerebral microbleeds, etc., causing serious damage to the neurological function of patients. Currently, there are three methods for measuring cerebral arteriosclerosis: (1) Injecting a contrast medium to observe the transit time of the contrast medium between cerebral arteries and veins. This method uses the method of contrast agent injection to understand the time of contrast agent passing through the cerebral arteries and veins. If there is arteriole disease, the contrast agent passing time will be prolonged. Based on...

Problems solved by technology

This method is an examination of small arterial lesions, but it is invasive and has the disadvantages of high operational risk and difficulty in widespread implementation

[0003] Since intracranial arteriole lesions are one of the main causes of cerebrovascular diseases, existing methods are either invasive, risky, expensive, or fail to directly understand the arteriosclerosis, and cannot meet clinical needs
