摘要： 目的 设计一种使语言与运动功能受损的肌萎缩侧索硬化症(ALS)患者能够在有需求的情况下自主呼叫医护人员的装置。方法 利用TGAM芯片采集并处理脑电信号，将提取得到的注意力特征值通过蓝牙传输至电脑，当注意力特征值超过正常范围时通过播音器向医护人员发出呼叫信号。结果 20名受试者 10次测试中，成功率平均为 81.5%，20 min内误判次数平均为 0.2。结论 该装置适用于语言与运动功能受损的ALS患者，满足日常护理工作的需求。

Abstract: Objective To design a device for the patients with amyotrophic lateral sclerosis (ALS), who are disable to speak and move, to call for the nurses independently when necessary. Methods The electroencephalographic signals were collected and processed with TGAM, and the extracted attention characteristic values were transmitted to a computer with Bluetooth. The loudspeaker would call the nurses when the attention characteristic value exceeds the normal range. Results In the testing process of 20 participants in 10 tests, the success rate was 81.5%, and the average misjudged frequence was 0.2 within 20 min. Conclusion The device can be used in the nursing of the patients with ALS to meet the needs of daily nursing work.
