针刺复式手法“得气”后特征参数采集系统设计与学习评价——以“赤凤迎源”补泻手法为例

Design and learning evaluation of characteristic parameter collection system after “Deqi” : Taking“Chifeng YingYuan” reinforcing and reducing manipulation as an example

为了让学生正确学习针刺操作手法,设计针刺复式手法“得气”后特征参数采集和评价系统,为针刺实践教育提供技术支持平台。以“赤凤迎源”补泻手法为例,利用柔性压力传感器对持针手指部位的特征参数进行采集,采用“逐点变精度”的一致性信息融合算法将多位专家的针刺操作手法的特征参数进行融合,获取最佳特征参数,并利用基于Shannon熵的连续变量互信息评价学生与专家手法操作的相关性,为学生提供操作指导与改进建议,从而实现针刺教学实践的优化。

This research aims to design a characteristic parameter collection and evaluation system of acupuncture compound manipulation after “Deqi”, providing a technical support platform for acupuncture practice education so as to improve students’ learning techniques. The system, taking “Chifeng YingYuan” reinforcing and reducing manipulation as an example, obtained the operator’s characteristic data based on the flexible pressure sensor, calculated the most accurate characteristic data value of the expert’s manipulation by using the consistent information fusion algorithm, and evaluated the correlation between students and experts based on the mutual information of continuous variables of Shannon entropy. It can provide students with operation guidance and suggestions for improvement, thus realizing the optimization of acupuncture teaching practice.
