Abstract

本发明公开了一种动物听觉检测电极定位装置，该定位装置包括微电极细针的针尖前段安装有螺丝和卡扣，微电极细针通过无线网络与听力检测装置相连接。本发明提供的一种动物听觉检测电极定位装置，用微电极细针在小鼠的耳部、头部等几个部位刺入，进行听觉功能检测，当针刺入到设定深度时，即将螺丝拧紧，卡扣卡定，就可以避免滑脱，而且，恒定的深度可以保证测量精度。

Description

一种动物听觉检测电极定位装置
技术领域
本发明属于动物听觉功能检测技术领域，尤其涉及一种动物听觉检测电极定位装置。
背景技术
听觉中枢的可塑性是指听觉传入冲动减少导致听觉中枢的形态和功能发生改变，这是今年来耳科领域的研究热点之一。采用耳蜗除术建立听觉剥夺动物模型，是研究听觉中枢可塑性的一种常用方法。但既往的动物模型多选用鸟类，豚鼠，大鼠，使用的方法多为耳毒性药物，噪声致聋，听力下降的过程度不稳定。因此，通过对小鼠建立稳定，可靠的小鼠听觉剥夺动物模型，对于听觉中枢可塑性的研究很有必要。
发明内容
本发明的目的在于提供一种动物听觉检测电极定位装置，旨在解决因为动物皮肤薄、针细，动物呼吸或电源线的牵拉可能导致电极滑脱。即使不滑脱，也可能因为深度改变导致测量误差的问题。
本发明是这样实现的：一种动物听觉检测电极定位装置，该定位装置包括微电极细针的针尖前段安装有螺丝和卡扣，微电极细针通过无线网络与听力检测装置相连接。
进一步，螺丝和卡扣距离针尖2mm。
进一步，螺丝可以拧紧。
进一步，卡扣能将微电极细针固定在动物身体上。
本发明提供的一种动物听觉检测电极定位装置，用微电极细针在小鼠的耳部、头部等几个部位刺入，进行听觉功能检测，当针刺入到设定深度时，即将螺丝拧紧，卡扣卡定，就可以避免滑脱，而且，恒定的深度可以保证测量精度。
附图说明
图1是本发明提供的动物听觉检测电极定位装置的结构示意图；
图中：1、微电极细针；2、螺丝；3、卡扣；4、听力检测装置。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
图1是本发明提供的一种动物听觉检测电极定位装置的结构示意图。为了便于说明，仅仅示出了与本发明相关的部分。本发明是这样实现的：该定位装置包括微电极细针1的针尖前段安装有螺丝2和卡扣3，螺丝2和卡扣3距离针尖2mm。螺丝2可以拧紧，卡扣3能将微电极细针固定在动物身体上。当针刺入到设定深度，将螺丝2拧紧，卡扣3卡定，就可以避免滑脱，而且，恒定的深度可以保证测量精度。微电极细针1通过无线网络与听力检测装置4相连接，进行数据传输。
本发明提供的一种动物听觉检测电极定位装置，用微电极细针在小鼠的耳部、头部等几个部位刺入，进行听觉功能检测，当针刺入到设定深度时，即将螺丝拧紧，卡扣卡定，就可以避免滑脱，而且，恒定的深度可以保证测量精度。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
