Description
技术领域
本发明涉及一种电极连接器,特别是电极连接器及阻抗指示器的集成装置。
背景技术
存在着在皮肤表面上使用电极来对电生理信号进行测量的多种应用,例如用于测量脑波(EEG)或心率(ECG)。这种电生理信号测量的准确度以及精确度,是取决于所测量的信号的强度以及可靠性。常规地测量电极-皮肤的接触阻抗,以确定电极是否正与皮肤处于良好接触,这样使得信号测量值代表了基础电生理活性。
在本领域已知的,对于通常用于医学应用(例如,如在DIN 42802标准中所述的EEG或ECG)中的电极而言,使用多个单一的连接器。在多电极设备上(例如EEG),通常将发光指示器定位在与其电连通的电极连接器附近,以指示电极阻抗是否在预设值或范围之外。例如,绿色指示器可以发光,以显示电极阻抗是令人满意的,或另一种颜色(典型地是橙色)的另一种指示器可以发光,以显示电极阻抗高至不可接受。
当存在多个电极时(各自都具有阻抗指示器),如用于测量EEG的仪器,对于阻抗指示器而言可供使用的空间是受限的。使电极以及它们附带的阻抗指示器的紧密布置,使得难以确定哪个阻抗指示器与特定的电极连通,因此使得恢复电极状态的任务变得困难。所需要的是这样的一种阻抗指示器,其可显示电极是否正在有效地工作、但是同时占用相对小的空间。
发明内容
目前,还没有一种结合有电极连接器以及与之电连通的阻抗指示器的仪器。本发明提供了一种将电极连接器以及阻抗指示器装置两者的功能结合(或合并)在单一设备中的仪器。本发明提供了一种包括电极连接器、阻抗指示器装置、以及光传输壳体的仪器。优选地,该仪器结合有定位装置,该定位装置用于将该仪器定位在用于锚定该壳体的接合装置上。优选地,该接合装置是一种适合的电路板。优选地,该定位装置是一种立柱。该阻抗指示器可以被定位在该壳体内的凹陷中。可替代地,该阻抗指示器可以被定位在该壳体的表面上的适当位置。该阻抗指示器可以是LED或某种其他适合的发光器件。优选地,该阻抗指示器可以指示该阻抗是否处于特别希望的操作范围之内或之外。优选地,该阻抗指示器通过发光来指示该阻抗的状态是处于操作范围之外。可替代地,当该阻抗处于操作范围之外时,该阻抗指示器能够停止发光。可替代地,当该阻抗处于操作范围之外时,该阻抗指示器能够改变所发出的光的颜色。本发明将透明或半透明材料用于该电极连接器以及阻抗指示器装置的壳体。在多电极设备(例如EEG)中,将两个信号测量装置结合到单一仪器中,会有利地节省了相当的空间。还有利地提供了明确的指示,即具体的电极连接是否正在适当地操作。在多种情况下,与现有技术相比较这是显著的优点,其中在现有技术,由于在邻近电极连接器与相关的阻抗指示器装置之间的空间有限,而不清楚哪个电极连接器以及阻抗指示器装置应引起注意。现有技术还可能出现多种情况,其中不清楚在电极连接器之上、之下、或一侧的指示器装置是否正在指示电极连接器没有正常地工作。

图1显示了根据本发明的电极连接器的实施方案,该电极连接器结合有阻抗指示器装置。在图1中,所述集成或整合的电极连接器与阻抗指示器1包括光传输壳体2,该光传输壳体具有管道5用于接合着电极引线连接器。优选地,该壳体2传导着光线。在图2中示出了图1所示的集成的电极连接器1的实施例的纵向横切剖视图。集成的电极连接器结合有导电销3,其与电极导线连接器4相接合。导电销3包括梢端6,其用于与接合装置7(例如图3所示的线路板)上面的导电电路相接合。图3显示了电极连接器与阻抗指示器1以及电极导线连接器4的侧视图。该电极引线连接器包含有通道11,其用于在沿箭头12的方向与集成的电极连接器1相接合时导电接合着该导电销3。
优选地,该导电销3具有大约1.5mm的直径,以符合DIN 42802标准(其在本领域中作为针对电极连接器的标准是已知的)的规格。该电极引线连接器可以是任何适合的连接器。
优选地,该壳体2由透明材料制成。可替代地,该材料可以是半透彻的、半透明的或具有另一种光传输特征,只要它能够传输来自指示装置的光即可。该壳体形成了管道5,用于引导电极引线连接器4以接合导电销3。
接合装置7发挥作用以锚定着壳体2、导电销3、以及电路(未显示),这样使得用于传导电生理信号的整个电路可以被传输以进行处理。接合装置7必须与阻抗监测电路相连通。
壳体2可以包括定位装置8,用于将壳体定位在接合装置7上,以将壳体2正确地引导并定位在接合装置7上,从而使得导电销3与该电路进行导电接合。优选地,该接合装置7可以是任何类型的电路板。

通过将指示装置安置在该光传输壳体的附近,由该指示装置传导或发生的任何光可以通过该光传输壳体进行传输,以向用户指示在电极导线连接器4与电路之间的电连接的状态。优选的,该指示装置9被壳体2中的凹陷10所容纳。这种优选的布置结构允许使指示装置(例如LED)被容纳在凹陷10中。
在操作中,该指示器装置的状态引起对电极连接器的阻抗的注意。在指示器装置的一个状态中,该电极的阻抗是处于对于传输电生理信号而言是所希望的操作范围之内。优选地,该指示器装置被点亮,以指示该电极阻抗处于它的操作范围之外。优选地,该指示装置是LED。优选地,当该电极导线与该连接器处于电连通时,该LED是可见地发光的。
