The design of a noninvasive cardiovascular function automaticdetecting instrument base on pulse wave

The pulse wave contains many of hemodynamic information, so obtain cardiovascular blood flow parameters by detecting the pulse wave is an important role in examination, treatment and guardianship process of the cardiovascular disease. Recently, most of the pulse wave acquisition and analysis require human intervention. The operators decide when to stop the acquisition by observing and determining the validity of the waveform. So, it needs higher professional knowledge to the operator, and the human factors are relatively large. In this paper, we designed the system to achieve pulse wave automatic collection, automatic sampling, automatic analyze, reduce the human impact, improve the detection speed and reduce the complexity of the operation, fleetly, conveniently and accurately detect the cardiovascular blood flow parameters.
