| 摘要 |
An electrode for effecting polarographic measurements in physiological media, in particular an oxygen electrode for the measurement of the partial pressure or tension of the oxygen in the human or animal body; encompassing a noble metal cathode which is sheathed by an insulating material, provided at the distal end thereof with a connector for an electrical power supply, as well as for an indicating and/or processing unit, and covered at the proximal end thereof with an oxygen-pervious, conductive membrane, as well as being conductively connected through the physiological medium with another anode. The noble metal cathode evinces the form of a piece of conductor cable having at least one noble metal wire, preferably gold wire, embedded in and extending through the insulating material, so as to provide a conductor wire. In a preferred embodiment of the invention, the noble metal cathode is constituted of a noble metal wire piece which is covered with an insulating lacquer, preferably a polyurethane.
