A Robot May One Day Draw Your Blood - Smithsonian

Scientists have developed a “venipuncture robot” that can automatically draw blood and perform lab tests, no humans needed

t’s distressing for the patient and perhaps even more distressing for the parents: your child needs a blood test, but the phlebotomist has trouble locating his tiny veins, and is forced to stick him again and again.

Researchers at Rutgers University say they may have found the solution: a “venipuncture robot.” The robot uses a combination of near-infrared and ultrasound imaging to find blood vessels, then creates a 3D image of the vessels before sticking the patient with a needle. The technology can potentially help make blood draws much quicker and easier, especially in difficult populations: children, the elderly, the obese, and people with dark skin (whose veins are more difficult to see on the surface).
