Date Jan. 16, 1986.Apparatus for the in-vivo measurement of blood oxygen levels in a patient, including an elongate probe adapted to pass into the oesophagus of the patient, a fibre optic light channel for illuminating the internal surface of the oesophagus a photosensor for monitoring light reflected from the internal surface of the oesophagus and a signal processor for determining from the reflected light signal the degree of oxygenation of blood in the internal surface of the oesophagus. A single optical fibre light channel may be utilized both to conduct light into the probe to illuminate the internal surface of the oesophagus, and to conduct light reflected from the internal surface of the oesophagus to the exterior of the patient.</p> |
