Abstract
An example system includes an elongated body, a fluorescent material, and a diffuse reflector. The elongated body defines a lumen and includes a proximal portion and a distal portion. The fluorescent material is configured to be in fluid communication with a fluid in the lumen. The diffuse reflector is configured to diffuse excitation light received from an excitation light source and direct the diffused excitation light toward the fluorescent material and diffuse the fluoresced light received from the fluorescence material and direct the fluoresced light toward a fluorescent light detector.
