Abstract
An optical sensor for use in clinical patient examination by spectrophotometric apparatus, having a body with softly deformable material which is conformable to a selected area on the body of the patient and internally-mounted electro-optical source and receivers for obtaining patient pathology data by transmission of selected wavelengths through a tissue volume adjacent the selected area, including substantially non-deforming light-transfer members disposed in alignment with the source and detectors and between them and the patient, to provide substantially constant and unchanging light-transfer passages or conduits therebetween. In the most preferred form, the light-transfer members comprise generally tubular elements having light-reflective interior walls, and the sensor body comprises either a layered structure of opaque, soft polymeric foam or the like (e.g. , cellular urethane) or a substantially one-piece, molded or other such structure of generally comparable or analogous material and characteristics.
