摘要
To separate electrolyte (70) within a chamber (66) formed beneath a dome-like housing (34) of a skin electrode from a signal transmission connector (34). and thus prevent corrosion of the terminal portion (38, 40) exposed to the interior of the chamber by the electrolyte, the interior of the chamber (66) is subdivided into two chambers (166a. 266a), by stretching a membrane (102) thereacross, the membrane (102) being ruptured upon depression of the contact terminal (34) of the housing. the electrolyte is retained solely within the chamber (266a) separate from the intenor portion (38. 40) of the terminal so that the corrosive influence of the electrolyte is prevented from attacking the metal of the terminal prior to use of the electrode, and during storage Preferably the chamber (166a) to which also the terminal is exposed may retain other liquids which are inert with respect to the electrode, and which. preferably are also separated from the electrolyte. such as a surfactant (170) to, additional- ly, permit a wider choice of respectively, electrolytes and surfactants without unintended leakage of electrolyte through the microporous membrane (26) closing off the housing instead of the membrane (102) a plastics bag may enclose the electrolyte within the chamber (66).
