Apparatus for the cutaneous determination of the oxygen partial pressure in blood
First Claim
Patent Images
1. An apparatus for the cutaneous determination of the partial pressure of gases in blood comprising an anode having a contact surface for application to an individual'"'"'s skin;
- a first cathode being a blood gas electrode having a first contact surface for application to an individual'"'"'s skin and having a gas consumption sufficiently low to enable representative partial pressure measurements;
a second cathode being a second blood gas electrode having a second contact surface and consuming practically all gas arriving at its contact surface, the two cathode electrodes being in structural unity with the anode to form a common contact surface;
a membrane covering said common contact surface for the application to an individual'"'"'s skin, and a heating means for heating the common contact surface for thermal stimulation of the blood perfusion.

Abstract
An apparatus for the simultaneous determination of the cutaneous blood gas concentration and of the blood gas availability for the correction of physiologically caused errors of the measured value of the cutaneous blood gas concentration by means of two heated blood gas electrodes in structural unity, of which one is distinguished by maximum gas consumption.
