Method for Locating a Transcutaneous Sensor on Skin

摘要

A method to aid in diagnosing at least one of infiltration and extravasation in Animalia tissue includes moving a light sensor over an epidermis of the Animalia tissue and evaluating a light signal while moving the light sensor. The light sensor includes first and second waveguides. The first waveguide is configured to transmit a first light signal that enters the Animalia tissue through the epidermis. The second waveguide is configured to transmit a second light signal. The second light signal includes a portion of the first light signal that is at least one of reflected, scattered and redirected from the Animalia tissue through the epidermis. The second light signal is evaluated while moving the light sensor to identify a location on the epidermis that has a minimal presence of underlying veins in the Animalia tissue.
