The accurate, non-invasive, measuring of the continuous arterial blood pressure waveform faces some difficulties and an innovative blood pressure measurement technology is urgently needed. However, the arterial blood pressure waveform plays an essential role in health care by providing diagnostic information and base for calculating several heart function parameters. The aim of this study is to introduce a novel non-invasive measuring system that can measure the arterial blood pressure waveform with high accuracy in comparison to an applanation tonometry system. The applied measuring device utilizes a new measurement strategy enabled by the OptoForce 3D force sensor, which is attached to the wrist at the radial artery. To validate the accuracy, 30 simultaneous measurements were taken with a Millar tonometer. For the simultaneously recorded non-invasive signals, the similarity was high (the average correlation was [Formula: see text]). The differences in the systolic and the diastolic blood pressure measured by the two systems are small. The average differences ([Formula: see text]) for simultaneously recorded systolic, diastolic, mean arterial and incisura pressures were: [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text], respectively. These results satisfy the AAMI criteria. Based on our results, this new system requires further development and validation against invasive arterial blood pressure monitoring in order to prove its usefulness in patient monitoring, emergency care, and pulse diagnosis.
准确、无创地测量连续动脉血压波形面临一些困难，因此迫切需要一种创新的血压测量技术。然而，动脉血压波形通过提供诊断信息和计算多个心功能参数的基础，在医疗保健中发挥着重要作用。本研究的目的是介绍一种新型无创测量系统，与压平式眼压计系统相比，该系统能够高精度地测量动脉血压波形。所应用的测量装置采用了由OptoForce 3D力传感器实现的新测量策略，该传感器附着在桡动脉处的手腕上。为了验证准确性，使用Millar眼压计进行了30次同步测量。对于同时记录的无创信号，相似度很高（平均相关性为[公式：见原文]）。两种系统测量的收缩压和舒张压差异很小。同时记录的收缩压、舒张压、平均动脉压和切迹压的平均差异（[公式：见原文]）分别为：[公式：见原文]、[公式：见原文]、[公式：见原文]和[公式：见原文]。这些结果符合美国医疗器械促进协会（AAMI）标准。基于我们的结果，该新系统需要进一步开发并与有创动脉血压监测进行验证，以证明其在患者监测、急救护理和脉象诊断中的实用性。
