Embodiment 1

[0054] The embodiment of the present invention provides a pulse wave velocity detection method, please refer to figure 1 , the method includes:

[0055] The classic principle of pulse wave velocity is obtained by measuring the body surface distance L of the arterial segment and the pulse wave transit time PTT, PWV=L / PTT. The existing recognized and mature measurement technique is to measure the velocity of the jugular-femoral pulse wave through the pressure pulse wave. Due to the shortcomings of the pressure pulse wave measurement method, which is difficult to fix and susceptible to interference, and the measurement site at the neck and femoral artery is special Complicated, highly demanding operation, relatively insufficient clinical practicability.

[0056] Based on this, the present invention provides comprehensive analysis and calculation of conduction velocity based on the signals of electrocardiogram, photoelectric blood flow, and pressure pulse wave, and obtains the pu...

Abstract

The invention discloses a method and device for detecting the wave speed of pulse waves, and relates to the technical field of bio-medicine. The method includes the steps that an electrocardioelectrode makes contact with skin at the corresponding position of a testee through an electrocardio detection sensor, and electrocardiosignal is measured; double-channel pressure pulse wave sensors are arranged on the surface of skin at the radial arteries of the left wrist and the right wrist of the testee respectively, and a first pulse wave signal and a second pulse wave signal are measured; a pulse oximeter signal is measured by a photoelectric sensor with a conventional method based on the pulse oximeter signal; a calculation method of the wave speed of the pulse waves is established based on the electrocardiosignal, the first pulse wave signal, the second pulse wave signal and the pulse oximeter signal. The technical problems that a detection device in the prior art is high in clinical operation difficulty, in the clinical measuring process, operation of professionally trained technicians is needed, and associated equipment is high in manufacturing cost are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pulse wave velocity detection method and device. Background technique [0002] The prevalence of cardiovascular disease risk factors in China is becoming more and more obvious, especially the aging population and the acceleration of urbanization, which have led to a continuous increase in the number of cardiovascular diseases. The pulse wave velocity (PWV) is an important index to measure arteriosclerosis, the higher the degree of arteriosclerosis, the greater the pulse wave velocity. [0003] At present, the most representative device for measuring pulse wave velocity is CF-PWV, the most authoritative gold standard for arteriosclerosis detection in the world. In addition, CF-PWV is used to determine the elasticity of large arteries, and the elasticity of peripheral blood vessels is not considered in the measurement. [0004] However, during the research and developme...
