Abstract
An electrode device for transcutaneously measuring the blood gas parameter and for sensing a bioelectrical signal and an electrode assembly comprising such an electrode device are disclosed. The electrode assembly for transcutaneously measuring a blood gas parameter and for measuring a bioelectrical signal comprises two separate electrode devices one of which further comprises an electrochemical measuring electrode system. The electrochemical measuring electrode system comprises a reference electrode of a potentiometric electrode system and an anode of a polarographic electrode system constituted by a single metallic body, a pH-electrode of the potentiometric electrode system, and a noble metal cathode of the polarographic electrode system. By means of the electrode assembly, coincident measurement of the blood gas partial pressures of oxygen and carbon dioxide and of a bioelectrical signal such as the ECG (Electrocardiography), the RR (Respiration rate) or the heart rate of the test person or patient is obtainable.
