AI Technical Summary

Technical Problem

Existing technologies struggle to effectively isolate deep physiological interference caused by bladder fullness during pelvic floor muscle electromyography (PEMG) signal acquisition, leading to inaccurate PEMG function assessment results.

Method used

By simultaneously acquiring respiratory abdominal pressure fluctuation signals and pelvic floor electromyographic signals, the visceral filling intensity is inverted using a machine learning model to generate defensive reflex background potential increments. Through spatial asymmetric attenuation compensation and a circuit breaker mechanism, deep interference in the pelvic floor electromyographic signals is removed to obtain pure pelvic floor muscle active function signals.

Benefits of technology

It significantly improves the accuracy and stability of pelvic floor electromyography assessment, avoids misjudgment of pelvic floor muscle spasm under bladder fullness, and ensures the medical reliability of assessment reports.

Abstract

本发明公开了一种临床女性盆底数据的处理方法和系统，涉及数据处理领域，包括：SOC芯片同步获取呼吸腹压波动信号及原始盆底肌电信号；SOC芯片提取盆底肌电信号能量包络线；SOC芯片提取波峰时间点与响应波峰时间点并将差值记录为相位延迟时间；SOC芯片将相位延迟时间输入至充盈强度反演模型中以输出内脏充盈强度系数；SOC芯片将该系数输入至采用增强学习构建的背景电位增量生成模型中以输出防御性反射背景电位增量；SOC芯片从原始盆底肌电信号中减除该增量以获得还原后的盆底肌主动功能信号。本发明解决了内脏充盈触发防御性反射导致肌电基线被污染而被误判为病理性痉挛的问题。
