Patent ID: 8577431

Claim:
An optical medical sensor configured to detect light attenuated by body tissue of a patient, the sensor comprising: a sensor housing comprising a first shell and a second shell pivotally connected together, the first and second shells each shaped to accept body tissue of a medical patient; an emitter disposed in the first shell, the emitter configured to emit light on the body tissue of the medical patient; a detector disposed on a submount in the second shell, the detector configured to receive light attenuated by the body tissue along an optical path; a shielding disposed between the emitter and the detector, the shielding comprising a substantially-transparent, electrically-conductive material in the optical path; and a cylindrical housing that at least partially encloses the detector, the cylindrical housing disposed on the submount and being at least partially made of a material that provides noise shielding for the detector, and wherein the cylindrical housing comprises a cover that includes the shielding.
