江苏一医学生为奶奶发明“癫痫报警器” 或将试生产

2017-08-14 07:46:52   中国青年网

尹旭演示癫痫报警保护装置。

这堪比临走时给师傅唐僧画上保护圈的孙悟空——22岁的江苏连云港小伙尹旭,赶在离家实习之前,为患有癫痫症的奶奶发明出了一款“癫痫报警器”。

该报警器利用患者发作时“牙关咬紧”这一症状,通过放在嘴里的硅胶牙套内导片,压缩闭合形成回路,使蜂鸣器鸣响,从而实现预警的目的。

尹旭是南京医科大学康达学院2014级临床专业学生。他对澎湃新闻记者介绍,自他记事起,奶奶便患有癫痫。癫痫是一种脑部慢性疾患,是由大脑一些神经细胞异常兴奋,反复放电,使大脑发生阵发性功能紊乱所致。

癫痫发作时,身体某一部位或整个身体短暂非自主性抽搐,有时伴有意识丧失和尿便失禁,严重时甚至能造成心脏停搏而死亡。因此,及时发现癫痫发作,对病人治疗非常关键。

据尹旭介绍,他奶奶基本上一个月发作一次,一般都在晚上12点到凌晨1点。今年春节,奶奶在深夜再次发病后,尹旭失眠了一夜。想到半年后便要离家前往三百里外的南京实习,尹旭忍不住害怕,若奶奶哪天发病了、他又不在身边,该怎么办?

他感到一种紧迫感,有没有一种可以及时监测到癫痫发作的仪器?在网上没能搜索到类似装置后,尹旭当下决定,自己做一个。

早在大二的时候,尹旭就跟随学长完成了两项发明创造,泌尿系统手术管理软件设计以及新型手术台设计。

“癫痫发作时,装置会发出警报,家属可以及时采取相应救治。”凌晨两点多,尹旭写下癫痫报警装置的初步设想。

有发明底子,也有了大致方向,但真正做起来还是不容易。新学期回校,尹旭的3名室友和学长倪誉伟也加入到该装置的发明中。

癫痫发作的特点各不相同,“奶奶发病时,全身抽搐、咬紧牙关,甚至有时咬破了舌头。”尹旭他们决定从“咬牙”这一症状入手,装置采用了有弹性的硅胶材料做牙套。在癫痫发作、牙关咬紧时,硅胶牙套帮助患者减少对于牙齿的损伤以及咬断舌头的风险。同时,牙套表面有左右对称的拱形硅胶柱体,也即减震柱,牙关紧闭的症状使减震柱压缩,上下T型导体闭合,形成闭合电路,通过蓝牙发射和接收,蜂鸣器发出警报。

从4月初着手开做,到6月份实验成功、设计完成,尹旭小团队利用每天课余的零散时间把这个“癫痫报警器”做了出来。
