基于光电容积脉搏波的动脉内皮功能障碍检测仪

Device for Endothelium Dysfunction Detection Based on Photoplethysmographic Method

目的:评估动脉内皮功能障碍,早期控制动脉粥样硬化。方法:根据反应性充血导致内皮依赖性血管舒张的原理,基于光电容积脉搏波设计了一种便携式动脉内皮功能障碍检测仪。结果:通过对高血压患者与正常人进行的对比实验,表明高血压患者已经出现了不同程度的内皮功能障碍。结论:该便携式动脉内皮功能障碍检测仪有望应用于动脉亚临床病变的研究、诊断和治疗效果评价之中。

Objective To evaluate endothelium dysfunction of arteries for early preventing atherosis. Methods A new portable device for detection of endothelium dysfunction by photoplethysmographic method was designed, which depended on the principle of reactive hyperaemia. Results Experiments between hypertensive and normotensive showed that different degree endotbelium dysfunction had emerged among hypertensive. Conclusion The proposed device has potential benefit to research, diagnosis and therapy evaluation for sub-clinic arterial disease.
