基于排序熵算法的麻醉深度检测系统设计

The Design of Anesthesia Depth Monitoring Based on Sort Entropy Algorithm

为辅助医生在手术过程中对患者麻醉深度状态的判断,设计了一种基于排序熵算法的麻醉深度检测系统。该系统主要包含3个部分,前端脑电预处理电路、排序熵算法数据处理电路和人机交互软件。前端电路主要包括各类放大电路和滤波电路;排序熵算法数据处理是基于stm32单片机完成;人机交互软件主要用于对测试结果进行记录显示等工作,辅助医生对患者麻醉状况的判断。依据以上方案制作了检测系统,并在实验室环境下进行了测试,能完成相关数据检测。

This Anesthesia depth monitoring based on Sort entropy algorithm is designed to help doctors judge the depth of Anesthesia during Operations,which included 3 parts： the front circuit of EEG preprocessing,the data processing circuit of Sort entropy algorithm and the Interactive software. The front circuit is mainly consisted of all kinds of amplification circuit and filter circuit. The Data processing of Sort entropy algorithm is based on stm32 SCM. The Interactive software is mainly used to record and display the result of the test. This design is based on the Scheme above and already got the results,which was tested in the Laboratory.
