  • Carbon dioxide sensor and method of determining partial pressure of carbon dioxide
    Patent number: 8003401
    Abstract: A carbon dioxide sensor and a method of detecting carbon dioxide using the sensor are provided, the sensor includes a closed chamber having as a wall portion thereof a substantially watertight, carbon dioxide-permeable membrane, two electrodes disposed in the chamber, and a film of substantially electrolyte-free liquid disposed in the chamber capable of simultaneously contacting the membrane and both of the electrodes.
    Type: Grant

  • Electrochemical sensor for in-vivo or ex-vivio measurements of the carbon dioxide partial pressure of living tissue
    Patent number: 7826880
    Abstract: A physiological sensing device for the measurement of pCO2 includes a closed chamber bounded, at least partially, by a carbon dioxide permeate e membrane (12). There are two electrodes (10) within the chamber. The chamber contains a substantially electrolyte-free liquid in contact with electrodes (10) and the membrane (12). The liquid contains a non-ionic excipient in order to prevent egress of water due to an osmotic gradient across the membrane (12) in use.

  • Carbon dioxide sensor and a method of determining partial pressure of carbon dioxide
    Patent number: 6541268
    Abstract: A carbon dioxide sensor including a closed chamber having as a wall substantially water-tight, carbon dioxide-permeable membrane and containing two electrodes. The chamber contains a film of de-ionized water contacting the membrane and both of the electrodes. The change in conductance of the water due to absorption of carbon dioxide is measured.
