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.
