Abstract: A visualisation aid device has a flexible PCB with a ring of surface mount LEDs around a circular opening. The LEDs emit at a wavelength to provide vein visualisation through a skin area exposed by the opening in use. A transparent membrane extends across the needle-access opening, and it has an adhesive on its skin-facing distal side. After insertion of the needle with the benefit of visualisation by the LEDs the substrate may be removed leaving only the membrane maintaining a sterile environment around the puncture site and helping to retain the needle in place.
