摘要
本文介绍一种用于无损伤诊断动脉系统疾病和静脉倒流性疾病的外周血管功能测定仪。它采用光电容积描记法原理,具有无损伤、简单方便、可靠灵敏、能定量计算等优点。文中介绍了仪器的设计原理和临床应用。
This instrument is made according to the principle of photoplethysmography. It can be used in diagnosis of arterial disease and venous flow reflux. It has been proved to be a noninvasive, reliable, sensitive and easy to use device, and it also provides AC and DC calibrations for quantitative analysis. The paper discribes the design, priciple and clinical applications of this instrument.
