ABSTRACT:
An electrode for percutaneous polarographic measurements and, in particular, an oxygen electrode for the percutaneous measurement of the partial pressure or tension of oxygen in human or animal bodies, including a carrier or support portion for the actual measuring electrode as well as, if the case requires, for the reference electrode; a gas-permeable membrane forming an electrode covering on the application side of the latter; an electrolyte introduced between the membrane and the electrode application surface, as well as connectors for the connection of the measuring electrode, respectively, the reference electrode, to a power supply and measuring unit. Only the measuring electrode is covered with a membrane merely on the application side thereof for the enclosure of an electrolyte, and the thus membrane-covered measuring electrode is inserted into a recess which is formed in the carrier portion so as to be readily separated from the carrier portion.
