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.　©2009　IEEE.
