A gastric probe comprises a light source (23) connected by a first fibreoptic connector (22) to a light dispersing member (21), said member being disposed in a body of liquid contained in a gas permeable container (20), said liquid containing a compound adapted to fluoresce upon excitation by said light source, the intensity of the fluorescence being dependent on the concentration of gas within said liquid, a second fibreoptic connector (29) extending from a location within the container to a detector adapted to produce a signal indicative of the concentration of gas in said liquid. |
