Abstract: An electrode device for transcutaneous PCO2 measurement with a pH-sensitive measuring electrode behind a CO2-permeable membrane, a reference electrode, and an electrical heating device for thermostating the measuring electrode and thermally stimulating the blood flow in the skin in the measuring area, the reference electrode being in direct heat-conductive contact with the electrical heating device and being designed so that it surrounds the measuring electrode. This permits compact design of the electrode in a very small size.

Abstract: For continuous or intermittent monitoring or recording of the in vivo plasma pH of a patient, the patient's acid base status is established with performance of at least one in vitro determination on a blood sample from the patient, and for a period of some hours thereafter, the patient's in vivo plasma pH is determined on the basis of this initial acid base status and the results of non-invasive measurements of the patient's actual blood Pco2.

Abstract: The invention relates to an electrochemical measuring device for transcutaneous measurement of arterial partial gas pressure, especially partial pressure of oxygen or carbon dioxide. The measuring device comprises an annular mounting member having a skin contacting surface adapted to be fastened to the skin surface of a patient, and a sensor of the type having a semi-permeable membrane adapted to be releasably connected to the mounting member. In the connected position of the sensor, the membrane is axially spaced from the skin contacting surface of the mounting member so that the membrane, the inner wall of the annular mounting member, and the skin surface define a measuring chamber which may be filled with a gel or another medium, if desired.

Abstract: A distortion measuring device for automatic distortion measuring is disclosed, having means in the form of tunable active band stop filters with associated control circuits for automatically tuning out the fundamental while transferring the harmonics to a measuring circuit. Further is disclosed a measuring circuit for such a device, in which the measuring of the harmonics is carried out as a measuring of the amplification in active filters provided with amplification control for obtaining constant output level. Such a measuring circuit is described combined with means for measuring the output level from the filters to enlarge the measuring range beyond the limit where the amplification control of the filters fail to maintain the constant value of the output level of the filters.
