My daughter has “rolling” veins. Honestly, whenever she has an venous puncture, the needle pokes and tears her surrounding tissues, searching for a vein. Only the most skilled phlebotomists (and one absolutely amazing nurse) can find her veins on the first try.
Enter a cool new invention (wish I’d written the patent for it). A “vein viewer” gives the practitioner an HD view of the veins in a person’s appendage. The vein viewer uses near-infrared light to locate the hemoglobin in the blood in the veins and project an image of the veins on the person’s skin, making finding the vein on the first poke much, much easier.
Is that cool or what?
