舰载机飞行员选拔用多色光脑电诱发闪光灯研制

Development of multicolor photoelectroencephalography evoked flash for selection of naval aircraft pilots

目的:研制一种多色光脑电诱发闪光灯,以鉴定舰载机飞行员选拔中是否存在光敏感性癫痫者。方法:该闪光灯由灯体、控制盒、支架3个部分组成。灯体内设置4排LED,分别发出红、黄、绿、橙4种颜色光;控制盒盒体上有信号、灯、电源3个插口和1个颜色转换开关,控制电路板固定于控制盒内底部;支架为双关节臂折叠式设计。将普通光脑电诱发闪光灯与该闪光灯进行对比,验证该闪光灯诱发光敏感性癫痫的效果。结果:清醒闭目条件下,多色光脑电诱发闪光灯与普通光脑电诱发闪光灯诱发光敏感性癫痫的人数对比,差异无统计学意义(P>0.05)。结论:该闪光灯可弥补普通光脑电诱发闪光灯的不足,可用于舰载机飞行员的选拔。

Objective To develop a multicolor photoelectroencephalography evoked flash to identify photosensitive epilepsy patients during the selection of naval aircraft pilots.Methods The multicolor photoelectroencephalography evoked flash was composed of a main body,a control box and a bracket.There were four rows of LED lights in the main body,which emitted four colors of light including red,yellow,green and orange,respectively;there were three sockets for signal,light and power and one color changeover switch on the body of the control box,and a control circuit board was fixed at the bottom inside the control box;the bracket had a double-jointed arm folding structure.The flash developed was compared with the coventional photoelectroencephalography evoked flash to verify its effect for inducing photosensitive epilepsy.Results There were no significant differences between the two flashes in the numbers of identified cases with photosensitive epilepsy when the subjects were under awake and closed-eye conditions(P>0.05).Conclusion The flash developed can make up for the deficiency of the coventional photoelectroencephalography evoked flash when selecting naval aircraft pilots.[Chinese Medical Equipment Journal,2024,45(7):112-114]
