As　the　rapid　increase　of　the　incidence　of　cardiovascular　disease,　more　and　more　people　begin　to　realize　the　importance　of　detecting　and　monitoring　the　cardiovascular　function.　However　the　traditional　non-invasive　cardiovascular　function　detecting　methods　trend　to　be　more　expensive,　complicated　and　settled,　which　are　not　suitable　for　real-time　and　fast　detecting.　A　novel　pulse　wave　collecting　and　analysis　system　is　designed　in　this　paper　to　achieve　the　goal　of　real-time　pulse　wave　collecting　and　cardiovascular　function　detecting,　which　is　portable　and　easy　to　use.　The　MCU　used　in　the　proposed　signal　collector　is　C8051F320　designed　by　Silicon　Laboratories.　A　USB-based　pulse　wave　signal　collector　with　appropriately　designed　I/O　interface　and　peripherals　is　designed　and　implemented　firstly　Then,　an　analysis　software　designed　for　Personal　Computer　(PC)　is　developed　based　on　radial　pulse　contour　characteristic　value　K　method.　Finally,　the　experimental　results　demonstrate　the　validity　of　the　proposed　system.
