鼻气管插管(NTI)是急诊气道管理中的关键操作,快速准确的喉部检测对保障患者安全至关重要。然而,现有基于视觉的辅助检测系统通常依赖高性能计算资源,存在显著推理延迟,限制了其在时间敏感且资源受限场景的应用。为此,我们提出 Mobile GlottisNet,一种专为嵌入式与边缘设备设计的轻量高效喉部检测框架。该模型融合结构感知与空间对齐机制,能够在复杂解剖与视觉条件下实现鲁棒的喉部定位。通过分层动态阈值策略优化样本分配,并引入基于可变形卷积的自适应特征解耦模块,支持动态空间重建。此外,跨层动态加权机制进一步促进多尺度语义与细节特征的融合。实验结果表明,模型在我们自建的 PID 数据集及临床数据集上均仅需 5MB 存储空间,设备端推理速度超过 62 FPS,边缘平台仍保持 33 FPS,展现出在紧急 NTI 应用中的巨大潜力。
原文摘要 · Abstract (English)
Nasotracheal intubation (NTI) is a vital procedure in emergency airway management, where rapid and accurate glottis detection is essential to ensure patient safety. However, existing machine assisted visual detection systems often rely on high performance computational resources and suffer from significant inference delays, which limits their applicability in time critical and resource constrained scenarios. To overcome these limitations, we propose Mobile GlottisNet, a lightweight and efficient glottis detection framework designed for real time inference on embedded and edge devices. The model incorporates structural awareness and spatial alignment mechanisms, enabling robust glottis localization under complex anatomical and visual conditions. We implement a hierarchical dynamic thresholding strategy to enhance sample assignment, and introduce an adaptive feature decoupling module based on deformable convolution to support dynamic spatial reconstruction. A cross layer dynamic weighting scheme further facilitates the fusion of semantic and detail features across multiple scales. Experimental results demonstrate that the model, with a size of only 5MB on both our PID dataset and Clinical datasets, achieves inference speeds of over 62 FPS on devices and 33 FPS on edge platforms, showing great potential in the application of emergency NTI.
