Palm type analyzer for sound waves of arterial pulses

Abstract

The invention discloses a palm type analyzer for sound waves of arterial pulses, and the palm type analyzer is characterized by comprising a sound wave receiver, a sound wave sensor, a signal receiver and intelligent equipment; the intelligent equipment is connected with the signal receiver; the intelligent equipment is provided with special software for controlling, displaying, replaying, storing, processing and analyzing the sound waves, is provided with a touch display screen and control keys, and displays, replays and stores digital information input by the signal receiver after processing and analyzing the digital information. According to the palm type analyzer, the sound waves of arterial murmurs are converted into an electric signal, and finally the electric signal is converted into visual graphs and numerical values, and manual judgment and identification is replaced with instrument analysis, and effective objective data is obtained to realize objective evaluation of the arterial murmurs. The intensity and the propagation direction of the sound waves generated when blood flow impacts a blood vessel wall during carotid artery pulsation can be measured noninvasively and dynamically to form images and parameters, which is conducive to medical diagnosis and follow-up visit, and clinical guidance, and the palm type analyzer has important significance on analysis of vessel lumen stenosis or expansion degree and hemodynamic changes.

Description

technical field [0001] The invention relates to an arterial pulse sound wave palm analyzer. Background technique [0002] Under normal circumstances, the flow of blood in the arteries is in a state of laminar flow, and no sound is produced. When the blood flow is accelerated and the vessel wall is abnormal such as stenosis or dilation, the blood flow will change from laminar flow to turbulent flow, and then form a vortex, impacting the vessel wall and vibrating. As the severity of luminal lesions increased, the intensity of arterial murmurs increased. The position of the bilateral carotid arteries is superficial, and vascular murmurs are most likely to be auscultated. [0003] In the past, a stethoscope was mainly used to identify carotid murmurs and interpret the intensity of murmurs manually. Only experienced specialists with more than 5 years of clinical training can effectively detect the presence and intensity of carotid murmurs, and there is very high heterogeneity ...

Problems solved by technology

During dynamic follow-up, the same examiner has recall bias, and comparisons between different examiners cannot be achieved. Therefore, effective dynamic follow-up data cannot be obtained
