摘要： An optical structure for combining light from a plurality of individual optical fibers into a single optical transmission device. The structure can be incorporated into the optical probe of a spectrophotometric instrument and includes a plurality of optical send fibers (116) having input and output ends and an optical light mixer having input and output ends. The light mixer assembly (110) effectively splices the send fibers (116) to the mixer fiber (152) and includes a connector formed by outer shell (160), inner shell (162), send fiber ferrule (164), mixer fiber ferrule (166) and alignment pin (168). The send fibers (116) extend through the connector outer shell (160) and into send fiber ferrule (164). The ends of the send fibers (116) are secured (e.g., by an optical grade adhesive) in an aperture (170) in the send fiber ferrule (164), cleaved, and polished to provide an optical-quality mating surface. Similarly, the end of the mixer fiber (152) extends through the connector inner shell (162) and into mixer fiber ferrule (166). The end of the mixer fiber (152) is located within an aperture (172) in the mixer fiber ferrule (166).

摘要： A naso-gastric reflectance spectroscopy probe. The probe includes an elongated flexible tube for insertion into a tubular body structure. The tube has a distal end with a lumen and suction apertures. One or more send and receive optical fibers extend through the lumen and have distal ends which terminate on the side of the tube near the distal end. Proximal ends of the optical fibers are adapted to be connected to a spectroscopy instrument. When positioned in a patient's stomach through the esophagus, a vacuum can be drawn through the tube to cause the optical fibers to be positioned in measurement contact with the tissue.
