Abstract: An oximetric sensor probe is movably coupled to a patient's finger to facilitate transillumination and detection of optical energy through a portion of the patient's finger without subjecting the finger to significant deformation. The finger is received within a receptacle having a cup-shaped closed end and an opposite open end that is rolled up upon itself and is adapted to be unrolled longitudinally along the finger to form a tubular enclosure which closely surrounds the finger. An optical source and an optical detector are arranged in spaced axial alignment with each other on opposite sides of the finger so that optical energy transmitted by the source through the finger is received by the detector. The detected light is analyzed to noninvasively determine the saturation of oxygen within the patient's blood.

Abstract: A low cost, disposable oximetric sensor including a finger cot probe to facilitate either the transillumination or transreflectance and the detection of optical energy emitted towards a patient's finger without subjecting the finger to deformation. The finger is received within a receptacle having a cup-shaped closed end and an opposite open end that is rolled up upon itself and adapted to be unrolled longitudinally along the finger to form a tubular enclosure in surrounding engagement with the finger. An optical source and an optical detector are arranged in spaced axial alignment with one another at opposite sides of the finger so that optical energy transmitted by the source towards the finger is received by the detector for non-invasively indicating the saturation of oxygen within the patient's blood depending upon the magnitude of the optical energy detected.
