Design of electrode fixation and positioning cap for transcranial electrical stimulation / 医疗卫生装备

ABSTRACT

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.
