An Intelligent Pelvic Floor Muscle Relaxation Self-Measuring Instrument Based on Piezoresistive Sensing and Nesting Design: A Clinical Concept and Feasibility Design Study

摘要: 目的：针对当前盆底肌松弛度的临床检测方法(如指诊、肌电检测等)存在侵入性强、仪器便携性差、操作专业性强的现状，为提高女性盆底健康的自我管理，研制一款基于压阻传感与叠套设计的智能盆底肌松弛度自测仪。方法：该自测仪采用叠套式结构，由内外嵌套的柔性探头、压阻式压力传感器阵列、转换电路及移动端应用程序组成。结果：该自测仪可作为居家自测工具，通过患者自主操作稳定采集盆底肌收缩频率和肌力数据。并且通过叠套结构满足不同用户对不同直径探头的需求，或进行二次检测。结论：该智能盆底肌松弛度自测仪适用人群广、操作简便、结构设计合理，可有效满足女性盆底肌松弛度的居家自主检测需求，为盆底康复训练提供数据支持，助力女性自我健康管理。

Abstract: Objective: In view of the current clinical detection methods for pelvic floor muscle relaxation (such as digital diagnosis, electromyography, etc.), which have strong invasions, poor portability of the instruments, and high professional operation requirements, in order to improve the self-management of women’s pelvic floor health, an intelligent pelvic floor muscle relaxation self-measuring instrument based on piezoresistive sensing and nesting design is developed. Methods: This self-measuring instrument adopts a nested structure and is composed of flexible probes nested inside and outside, an array of piezoresistive pressure sensors, a conversion circuit and a mobile application program. Results: This self-measuring instrument can be used as a home self-measuring tool to stably collect pelvic floor muscle contraction frequency and muscle strength data through the patient’s independent operation. And through the nested structure, it meets the demands of different users for probes of different diameters or conducts secondary detection. Conclusion: This intelligent pelvic floor muscle relaxation self-measuring instrument has a wide range of applications, is easy to operate, and has a reasonable structural design. It can effectively meet the home self-detection needs of female pelvic floor muscle relaxation, provide data support for pelvic floor rehabilitation training, and assist women in self-health management.
