Abstract
A fixation ring for a transcutaneous gas sensor probe adapted to be removably mounted on the probe with a bore in the ring communicating with the electrodes of the probe. The fixation ring includes a membrane mounted therein which is tensioned in cooperation with the probe when the fixation ring is attached to the probe at which time the membrane permits only gases to which it is permeable to pass through the bore in the fixation ring and into an ion solution in contact with the electrodes of the probe. A cap member removably mountable on the fixation ring is provided with a resilient disc for depressing the membrane to prevent excessive ion solution and any entrapped air from accumulating adjacent to the electrodes.
