研制了一种测量动脉扩张、脉搏和压力波形的传感器，并对其进行了评价。该系统包括一个磁性传感器，它被施加并固定在动脉血管上，没有任何血管收缩，从而避免了狭窄。该测量原理可以通过硅胶管的体外实验和动物模型的体内实验来验证，从而揭示了真实血管的非线性粘弹性特性。该传感器能够提供动态变化的动脉直径的绝对测量。通过对传感器的标定，可以基于所述方法开发出连续测量血压和其他心血管参数的长期监测系统。这将改进对高危患者的诊断，并使更好的、特定的治疗成为可能。
A novel sensor for measuring arterial distension, pulse and pressure waveform is developed and evaluated. The system consists of a magnetic sensor which is applied and fixed to arterial vessels without any blood vessel constriction, hence avoiding stenosis. The measurement principle could be validated by in vitro experiments on silicone tubes, and by in vivo experiments in an animal model, thereby indicating the non-linear viscoelastic characteristics of real blood vessels. The sensor is capable to provide absolute measurements of the dynamically varying arterial diameter. By calibrating the sensor, a long-term monitoring system for continuously measuring blood pressure and other cardiovascular parameters could be developed based on the method described. This will improve diagnostics for high risk patients and enable a better, specific treatment.
