Abstract

The invention provides a device for noninvasive acquiring centre artery pressure waveform and relevant parameters and an acquiring method thereof. The device is characterized by comprising a blood pressure signal collecting unit, a pulse signal collecting method, a pulse signal process unit and a waveform reconstruction unit; the acquiring method comprises the following steps: collecting artery information formed by radial artery pulse wave and brachial artery blood pressure value, reconstructing human body centre artery pressure waveform in the radial artery pressure waveform through the adoption of the transfer function applied for Chinese population, and acquiring the centre artery pressure waveform and the relevant parameters. According to the device and the method provided by the invention, the testing procedure is simple, the operation is convenient, and the non-invasive is realized, so that the device can be used for well satisfying the requirements of the cardiovascular disease screening and general survey of Chinese population.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a device and method for non-invasively acquiring central artery pressure waveforms and related parameters. Background technique [0002] The central arterial pressure waveform is composed of two parts: the forward wave generated by the left ventricular ejection and the reverse wave returning when encountering peripheral vascular resistance. Due to the difference in arterial thickness, elasticity, and return time of reflected waves at different positions of human blood vessels, there are differences in the shape and amplitude of arterial pressure waveforms, which makes peripheral blood vessels unable to reflect the state of central arteries well. However, current studies have shown that central arterial blood pressure is more closely related to cardiovascular disease than peripheral arterial blood pressure. Therefore, acquisition of central arterial pressure wavefo...
