ABSTRACT
In order to obtain the three-dimensional pulse information and blood pressure waveform needed in the study, a radial artery simulation platform with programmable controlled injection pump as the core was constructed by using the circulation theory of human cardiovascular system and pulse wave formation mechanism. Gaussian function model was selected to synthesize multi-type pulse wave to program and drive the platform. The three-dimensional pulse information and blood pressure waveform of the simulated radial artery were collected by binocular visual pulse detection system and pressure transmitter respectively, and the platform stability and repeatability were tested by Pearson correlation. The experimental results show that the radial artery simulation platform is stable, reliable and repeatable, and can generate multiple types of three-dimensional pulse information and blood pressure waveform at the simulated radial artery. The platform is simple in structure, low in cost, and produces many types of pulsating flow. It provides an experimental research platform for revealing the relationship between the three-dimensional pulse information of radial artery and the change of pressure inside the vessel, as well as the prediction of blood pressure waveform from the three-dimensional pulse information.
