ABSTRACT:
A polarographic catheter-shaped probe for determining analytical data of logical fluids of human beings, of animals, or of plants, and having a cathode, an anode and an electrolyte connecting the two, which are surrounded by a flexible sheath sealed in the tip region of the cathode by an ion-impermeable but gas-permeable membrane, wherein the anode is arranged at the distal end of the catheter shaft away from the cathode tip, the electrolyte extends from the anode to the tip of the cathode within the probe, and the anode and cathode are connected to a terminal jack for measuring instruments located at the end of the probe facing the anode. The jack optionally contains a supply chamber for the electrolyte, which is connected in a liquid-tight manner to the one end of the catheter shaft.
