Objective: To acquire the related cardiovascular parameters by measuring the pulse noninvasively. Methods: The modified theory of Frank is introduced to analyse the relationships of the cardiovascular parameters. The cardiovascular system parameters can be achieved through the pulse wave changes. This system includes piezo-film transducer

signal amplifier

data collecting and data analyzing equipment. Varieties of pulse diagram can be showed in omnidirectional and multifunctional ways. Results: Twenty people being in different ages are detected by this system and invasive detecting at the same time. The test indicates that the errors are not more than 1%. Conclusion:The system realizes the qualitative and quantitative analysis of cardiovascular parameters. It presents a novel method for detecting the cardiovascular diseases and provides a powerful tool for traditional Chinese medicine diagnoses.
