Description

一种电子音叉装置 技术领域
本发明属于知觉检测技术的领域，更具体地说，是涉及一种用于检测病患振动知觉的电子音叉装置。
 背景技术
近年来，糖尿病的发病率逐年上升，其中糖尿病足(diabetic foot)是一种非常严重的慢性并发症。造成糖尿病足的原因主要是感觉运动神经病变与周边动脉血管病变，最后病患皆会因血液循环不足造成足部组织坏死，严重时甚至会造成截肢。糖尿病的运动神经病变主要以周边神经症状为主，最严重的情形就是让患者的足部丧失感觉，进而失去感觉保护作用，此为糖尿病患容易产生足部溃疡的重要原因之一。临床上糖尿病患往往无法正常察觉肢体末梢的异常，甚至许多感觉保护作用丧失的病患都认为自身的末稍循环状况是正常的。因此，医护人员无法单凭问诊来诊断出糖尿病患是否丧失感觉保护作用，必须利用机械式音叉对病患进行振动知觉测试。
测试时，先让患者闭上眼睛，医护人员敲击音叉使其振动，将音叉放置于病患的大脚趾关节或指甲上。请病患主动表示有无振动感，当患者表示已无振动感，医护人员读其音叉上所显示的刻度。刻度≧5，代表正常；刻度＜5或完全无振动感，则代表异常。
然而，使用机械式音叉于病患的知觉测试时，由于医护人员必须以肉眼读取音叉上的刻度，所以检查结果乃相当主观，数据上容易有误差，甚至可能有误判的情形发生。另外，传统音叉的使用对象通常限定于有丰富量测经验的医护人员，因此无法允许糖尿病患者在家中由家人或朋友协助检测，这对糖尿病患而言，相当不便。
