Abstract
A fiber optic probe placement guide minimizes sampling errors during optical sampling of a tissue measurement site by allowing repeatable placement of the fiber optic probe at a targeted tissue measurement site. A mount, contoured to conform to the shape of the tissue measurement site, typically the arm of a human subject, contains an aperture for receiving a fiber optic probe. A temperature probe on the contact surface of the guide allows for monitoring of surface temperature within the vicinity of the tissue measurement site. Crosshair slots in the mount align with corresponding crosshairs at the tissue measurement site. The fiber optic probe placement guide is affixed to the tissue measurement site by means of adhesive tape or fastenable straps. Guideposts on the external surface of the mount are received by corresponding receptacles on a subject interface bearing the fiber optic probe to facilitate alignment of the fiber optic probe with the aperture.
