Reusable medical electrode having disposable electrolyte carrier

摘要

A medical electrode particularly suited for use as an EEG electrode comprises initially separated electrode conductor and electrolyte carrier components which are united prior to use of the electrode. The electrolyte carrier component comprises a disposable adhesive patch adhered to a disposable sponge member soaked with an electrolyte. The electrode conductor component comprises a reusable conductor ring having an affixed lead wire terminating with a plug-in device for effecting attachment to a monitoring instrument. Prior to use the electrolyte carrier components are stored in one or more evaporation resistant tray devices.
