Abstract
The present application describes a urine sensing probe and a system for detecting urine. The urine sensing probe includes a needle having a tubular portion and one or more optical fibers positioned within the needle. The one or more optical fibers have a distal surface that is oriented towards a beveled distal section of the needle and is oriented to one of its lateral sides. The distal surface of the one or more optical fibers ranges from about 90 to a critical angle with respect to a vertical axis of the needle. The present application also describes a system for sensing urine including a urine sensing probe.
