A flexible, multifunctional, and intelligent analgesic bracelet was proposed in this article to alleviate symptoms of pain. Based on the theory of wrist-ankle acupuncture in traditional Chinese medicine, transcutaneous electrical nerve stimulation is the technical basis of the method. A set of targeted circuit system capable of generating adjustable electrical stimulation signals to simulate filamentary acupuncture was designed. The system architecture includes a wireless communication module, a signal control module, a stimulus signal generation module, and a wearable, flexible bracelet. In addition, a pain assessment interface with a visual analog scale was designed to assess pain levels. Two comparative experiments were designed, involving a custom pain assessment scale and hand-held dolorimeter that were performed before and after wearing the bracelet to verify the analgesic effect of the bracelet. The results showed that the wrist-worn analgesic bracelet is significantly effective in alleviating pain in various parts of the human body.
本文提出了一种灵活、多功能、智能化的止痛手环，用于缓解疼痛症状。该手环基于中医腕踝针理论，以经皮神经电刺激为技术基础，设计了一套能够产生可调电刺激信号以模拟丝状针灸的靶向电路系统。系统架构包括无线通信模块、信号控制模块、刺激信号产生模块和可穿戴的柔性手环。此外，还设计了一个带有视觉模拟量表的疼痛评估界面，用于评估疼痛程度。设计了两个对比实验，分别使用定制的疼痛评估量表和手持式疼痛测定计，在佩戴手环前后进行测试，以验证手环的镇痛效果。结果表明，腕戴式止痛手环在缓解人体各部位疼痛方面具有显著效果。
