经颅电刺激定位与固定帽的设计

Design of electrode fixation and positioning cap for transcranial electrical stimulation

目的:设计一种经颅电刺激定位与固定帽,用于经颅电刺激固定电极并实施精确定位。方法:该装置包括定位帽、软橡胶龙骨支架、镶嵌螺母、连接螺栓、电刺激垫片等,将电极插接在目标位点的电刺激垫片中,通过调节螺栓的入槽深度改变电极固定垫与颅脑皮肤的贴合程度,从而实现经颅电刺激治疗设备电极与患者颅脑之间的快速精准定位与紧密贴合式固定,为患者脑部实施可靠稳定的电刺激治疗。结果:与传统方法相比,该装置单次固定时间短、脱落率低、患者满意度高,很好地解决了电极定位相对不精确且操作繁杂、固定不牢固的问题。结论:该装置结构简单、制作容易、成本低且固定效果好,适用人群及电刺激设备范围广,一定程度上提高了经颅电刺激治疗技术的可靠性。

Objective To design a new type of rehabilitation device to execute electrode fixation and precision positioning during transcranial electrical stimulation.Methods The device was composed of a positioning cap,a soft rubber keel scaffold,an inlaid nut,a unionbolt,an electrical stimulation shim and etc.The electrode was put into the shim at the target site,and fixation and positioning were realized by regulating the depth of the bolt into the slot to change the attachment between the electrode fixing cushion and cranial skin,and then electrical stimulation therapy could be carried out reliably and accurately.Results The device gained advantages over the traditional means in fixation time in one time,dropping-off rate,patient satisfaction and easy operation.Conclusion This device behaves well in simple structure,easy manufacture,low cost,fixation and large applicability to kinds of population and electrical stimulators,and enhances the reliability of transcranial electrical stimulation therapy to some extent.
