本研究目的：本文报道了一种新设计的双传感脉象诊断仪（BSPDI）的构造和功能，该仪器具有一个与机器人手指系统相连的压力 - 位移双传感系统（PDBSS）。BSPDI用于根据指法规则模拟三部九候（TPNI），在脉诊时涉及手腕上寸（CUN）、关（GUAN）、尺（CHI）三个部位的浮（Fu）、中（Zhong）、沉（Chen）三个层次。
材料与方法：将应变片和聚偏氟乙烯压力传感器集成为一个PDBSS，以分别记录指法技巧并感知医生的指尖感觉。利用医生指尖与BSPDI之间相应的感觉和诊脉位移以及脉诊与九个TPNI位移之间的关系来确定BSPDI的可行性。
结果：使用PDBSS记录了代表医生指法技巧的TPNI位移。在此情形下，将带有压力传感器的BSPDI机器人指尖放置在记录的九个TPNI位移处。压力传感器记录脉象信号以模拟医生的指尖感觉。由BSPDI和中医医生对两组健康状况不同的参与者进行评估。两组得到了相似的诊断，双向方差分析结果表明，脉诊与诊脉位移和部位的临床经验高度相关。
结论：新型BSPDI可成功模拟中医医生的指法技巧，因为该技术在代表指尖感觉的九个TPNI位移处获得了脉象信号。（c）2012爱思唯尔有限公司。保留所有权利。
Aim of this study: This paper reports the construction and functionality of a newly designed Bi-Sensing Pulse Diagnosis Instrument (BSPDI) with a Pressure-Displacement Bi-Sensing System (PDBSS) coupled to a robot finger system. The BSPDI is used to simulate the three positions and nine indicators (TPNI) using the finger-reading rule, which addresses the three levels of superficial (Fu), medium (Zhong), and deep (Chen) at the three positions of distal (CUN), middle (GUAN) and proximal (CHI) on the wrist during pulse diagnosis.Materials and methods: A strain gauge and polyvinylidene fluoride pressure sensor were integrated as a PDBSS to separately record finger-reading skills and sense a physician's fingertip sensations. The corresponding sensation and pulse-taking displacement between the physician's fingertips and the BSPDI and the relationship between the pulse diagnosis and the nine TPNI displacements were used to determine the feasibility of the BSPDI.Results: TPNI displacements, representing a physician's finger-reading skill, were recorded using a PDBSS. In this scenario, the BSPDI robot fingertips with pressure sensors were placed at the nine recorded TPNI displacements. The pressure sensors recorded pulse signals to simulate a physician's fingertip sensations. Two groups of participants with different health statuses were evaluated by both the BSPDI and TCM physicians. Both groups received similar diagnoses, and the results of a two-way ANOVA indicated that pulse diagnoses were highly related to the clinical experiences of the pulse-taking displacements and positions.Conclusions: The novel BSPDI can be used to successfully mimic a TCM physician's finger-reading skill, as this technique obtained pulse signals at the nine TPNI displacements representing fingertip sensations.
