Abstract: An apparatus for determining spectral absorption by a specific substance in a fluid having an energy source (48, 49), a sensor (34), an interface device, a support structure, and a connector (14). The energy source (48, 49) directs energy having a predetermined wavelength into the fluid. The sensor (34) produces an electrical output reflecting the energy it senses and indicative of the sprectral absorption of the specific substance. The interface device generates a reference voltage to allow the apparatus to cooperate with prior art devices. A support structure secures the other elements in proximity to the fluid. The connector (14) communicates electrical signals to a remote display device.

Abstract: A probe (110) useful for invasively monitoring the oxygen saturation level of blood in the tissue walls of an anatomical cavity, for example in the esophagus, rectum or vaginal cavity of a human patient. The probe (110) may also be suitably employed in many veterinary applications. The probe (110) generally comprises a chassis (112) with an electrical connector extending from the proximal end of the chassis and terminating at a plug (132) configured for connection to a pulse oximeter box. The probe (110) further includes an optics assembly (126, 128) configured for either reflective or transmissive optics and configured to generate and transmit electrical signals that are indicative of the dynamic oxygen saturation level of blood in the wall tissue. In a further embodiment of the invention, the probe (110) may include a deployment device (119) attached to the chassis (112), for biasing the optics assembly (126, 128) into the tissue wall of the anatomical canal. The deployment device (118) may be, for example, a spring, a balloon or any other biasing device which urges the optics assembly into the wall tissue of the anatomical cavity. Further, the oximetry sensing assembly may be configured as part of an esophageal stethoscope having other sensing devices, for example, a temperature sensor (122), a pacing assembly (135), and an acoustic monitor (124).
