摘要

本文介绍了一种利用磁感应技术研制的新型柔性管制导磁定向传感器。柔性管在医疗应用中具有重要作用,用于输送营养物质或新鲜空气,但插入管在很大程度上取决于经验丰富的操作人员。虽然x射线已被应用于检测试管的位置,但它耗时,成本高,体积大,不实用。相反,由于磁性传感器的紧凑性,已经研究了用于位置/方向检测的磁性传感器。本研究开发了一种基于磁感应的紧凑型定向传感器;磁场发生器和探测器沿柔性管设计。利用扩展分布多极子(eDMP)模型的磁场建模方法,对具有设计参数的磁互感进行了分析和优化。对传感器的性能进行了数值模拟,并与实验结果进行了比较。结果表明,该方法在较宽的工作范围内具有较高的精度,具有广泛的应用前景。

A novel magnetic orientation sensor for intubation procedures
This paper presents the development of a novel magnetic orientation sensor of a flexible tube guidance using magnetic induction. A flexible tube has an important role as medical applications, for passing nutrients or fresh air, but inserting the tube has been largely dependent on experienced operators. Although X-ray have been applied to detecting the location of the tube, it is time consuming, high cost and they are bulky, which are not practical. On the contrary, a magnetic sensor has been studied for position/orientation detection due to compactness. In this study, a compact orientation sensor based on magnetic induction has been developed; both field generator and detector are designed along the flexible tube. Magnetic mutual inductance with design parameters are analyzed and optimized for an operational range of orientation angle along with magnetic field modelling method referred to Extended Distributed Multiple-Pole (eDMP) model. Performance of the sensors are numerically simulated and compared to experimental results. The comparisons show the accuracy in wide operational range and potentials in using many applications.
