中文摘要:

      目的 通过对溺水自主救援产品的再设计，为游泳人群寻找更好的溺水自救途径。方法 以溺水者的自主救援需求为导向，运用观察法与情景分析法对溺水者的各种生理表象进行观测、记录及实验比对，确定“呛咳”是有效判断溺水的唯一表象。借助“呛咳”与“吞咽”时喉部肌肉运动方式的一致性，运用吞咽监测技术间接识别“呛咳”的发生，并通过实验验证水下环境中吞咽监测技术识别“呛咳”的可行性。结果 溺水状态下的“呛咳”信号呈现特征性变化规律且与正常“呛咳”信号差异显著。结论 吞咽监测技术能够准确识别溺水状态，并有效应用于溺水自主救援产品设计中，其提高了溺水者的自救成功率，减少了溺水事故的发生。

英文摘要:

      The work aims to find a better way for swimmers to save themselves from drowning through the redesign of the drowning self-rescue products. Guided by the self-rescue needs of drowning people, observation, recording and experimental comparison of various physiological phenomena of drowning people were carried out by using observation method and situational analysis, determining that "coughing" was the only phenomenon that could effectively judge drowning. With the help of the consistency of throat muscle movement during "coughing" and "swallowing", the swallowing monitoring technology was used to indirectly identify the occurrence of "coughing", and the feasibility of using swallowing monitoring technology to identify "coughing" in the underwater environment was verified through experiments. The results showed that the "coughing" signal in the drowning state showed a characteristic change pattern and was significantly different from the normal "coughing" signal. In conclusion, the swallowing monitoring technology can accurately identify the drowning state, and can be effectively applied to the design of drowning self-rescue products. It improves the success rate of self-rescue and reduces the occurrence of drowning accidents.
