Abstract

The invention discloses a noninvasive artery elasticity detection method and device, and relates to the technical field of clinical detection. The device comprises a blood pressure detection unit, a blood flow detection unit and a data processing unit, the blood pressure detection unit comprises two force sensitive devices, and the blood flow detection unit comprises an ultrasonic transmitting module and an ultrasonic receiving module. When artery elastic detection is carried out, firstly, the two force sensitive elements are placed at the same pulse position at a certain interval, and pulse wave signals are obtained in real time; meanwhile, the ultrasonic transmitting module and the ultrasonic receiving module which are placed at the same pulse position obtain an ultrasonic transmitting signal and an ultrasonic echo signal reflected by blood by using a Doppler ultrasonic detection technology. Then the pulse wave signal, the ultrasonic transmitting signal and the ultrasonic echo signal are transmitted to a data processing unit, and a blood pressure value and a blood flow value are obtained after processing. And finally, calculating the arterial elasticity index through the blood pressure value and the blood flow value. The blood pressure and blood flow parameters are synchronously obtained, and the obtained arterial elasticity index is more accurate.

Description

technical field [0001] The invention relates to the technical field of clinical detection, in particular to a non-invasive arterial elasticity detection method and device. Background technique [0002] Arterial elasticity refers to the expandability of arteries under a certain pressure, which depends on the size of the arterial lumen and the hardness of the arterial wall. It is one of the key indicators reflecting the structure and function of blood vessels. Accurate detection of arterial elasticity is not only helpful for early detection of vascular lesions and screening of patients with cardiovascular disease in subclinical state, but also conducive to monitoring the condition of patients with cardiovascular disease, cardiovascular risk stratification and intensifying guidance for high-risk patients It has important clinical significance and value in the detection and evaluation of arterial elasticity. [0003] At present, non-invasive techniques for evaluating arterial e...
