Description
Technical Field
The invention relates to a probe for detecting the local pulse wave velocity of deep aorta and middle artery in a body, belonging to the field of biomedical engineering detection.
Background
Cardiovascular and cerebrovascular diseases caused by arteriosclerotic diseases, such as coronary heart disease, cerebral apoplexy and the like, become a main cause of death of human beings due to diseases all over the world. Research shows that the pulse wave velocity is directly related to the arteriosclerosis degree, and the increase of the arteriosclerosis degree leads to the increase of the pulse wave velocity, so that the pulse wave velocity is an independent prediction factor of the cardiovascular and cerebrovascular diseases. The accurate measurement of the pulse wave velocity has important significance for the early diagnosis of arteriosclerosis diseases and cardiovascular and cerebrovascular diseases caused by the arteriosclerosis diseases.
At present, coronary artery imaging is mainly used for image examination and diagnosis of deep aorta and middle artery lesions of human bodies such as coronary artery. The disadvantages of such methods are: the equipment is expensive and the operation is complex. Early understanding and diagnosis of the extent of coronary lesions by non-invasive methods has become a focus of research. The method for diagnosing the occurrence and development of deep-layer large and medium arteriosclerotic lesions of human bodies such as coronary artery and the like by measuring the wave velocity of local pulse waves is a direct non-invasive method. The existing measurement of the local pulse wave velocity of the coronary artery mainly comprises the steps of scanning the pulse wave propagation time at a certain section of specific distance of the coronary artery through high-frame-frequency ultrasound, and dividing the propagation time by a fixed distance to obtain the local pulse wave velocity. However, the detection of the propagated pulse wave is greatly influenced by external interference, and the reference time between waveforms is difficult to accurately determine, so that a large error is generated in the estimation of the wave velocity of the pulse wave. The invention provides a probe for detecting the local pulse wave velocity of the major and middle arteries in the deep layer of a human body, and aims to avoid mutual interference among pulse waves in the measurement process and improve the accuracy of reference time.
Through literature search, the public report same as the technology of the invention is not found.

And sending the received ultrasonic radio frequency echo signal to ultrasonic imaging processing, and extracting a pulse displacement sequence wave transmitted by the aortic arch section. And determining the time reference point of the serial pulse displacement waves by the electrocardio start, and calculating the pulse wave delay time. And finally, calculating the wave velocity of the local pulse wave of the aortic arch according to the detection distance, and averaging the wave velocities of the pulse waves measured at intervals of a period of time to obtain the final detection result.
