摘要

本研究的目的是为糖尿病患者的外周神经系统设计和制作一种机械振动评估工具。外周感觉神经病变与振动感知阈值(VPT)之间存在很大的相关性。外周感觉神经病变可通过使用为此目的而制造的 VPT 测量仪器进行 VPT 测定来确定。所设计的设备可帮助确定阈值并跟踪任何渐进变化或趋势。所设计的设备由两个主要部分组成:硬件和软件。硬件部分包括一个直流电源电路、一个 Arduino NANO、一个显示器、一个用于电气隔离电路的隔离 MOSFET 驱动器、一个传感器驱动器和一个传感器头。软件部分在 Arduino 上使用 C 语言编程,以生成信号并显示传感器的电源电压。测试结果包括:1)电压设置结果(5-30 伏),比较设计装置和数字万用表显示屏上的电压值,平均误差为 0.75%;2)根据传感器头按压测试结果,Vibrotest 数字生物血压计和拟议装置的按压重量相差±0.02 克;3)设计装置的电气安全测试结果符合 IEC60601-1 标准。(IEC:国际电工委员会)。

A Design and Construction of the Vibration Perception Threshold Measurement Device for Diabetes
The purpose of this study was to design and build a mechanical vibration assessment tool for diabetic patients’ peripheral nervous systems. There is a substantial correlation between peripheral sensory neuropathy and vibration perception threshold (VPT). Peripheral sensory neuropathy has been identified by VPT determination utilizing the VPT measurement instrument built for that purpose. The designed device can assist in determining the threshold and tracking any progressive changes or trends. This designed device consists of two main components: hardware and software. The hardware part includes a DC power supply circuit, an Arduino NANO, a display, an isolation MOSFET driver for the electrical isolation circuit, a transducer driver, and a transducer head. The software part uses C programming on the Arduino to generate signals and display the transducer supply voltage. The testing results consist of 1) the voltage settings results (5–30 volts) comparing the voltage values on the display between the designed device and a digital multimeter, which has an average error of 0.75%, 2) According to the transducer head pressing test results, the Vibrotest Digital Biothesiometer and the proposed device had different pressing weights of ±0.02 g, and 3) the electrical safety testing results of the designed device is in the standard of IEC60601-1.
