ABSTRACT:
A multi-layered structure in the form of a disposable patch is described for supporting a light source and useful in conjunction with procedures for the non-invasive visualization of veins, arteries or other subcutaneous structures of the body or for facilitating intravenous insertion or extraction of fluids, medication or the like, which in a representative embodiment includes a coupling layer for interfacing and optically coupling with the body surface and conforming to the surface topography of the body portion of interest, a ring for supporting a light source, and a reflective layer between the source and coupling layer for redirecting light reflected from the body surface back through the coupling layer.
