Watch this robot draw blood from a patient

Many of the common concerns with giving blood – shaky needles, elusive veins -- may be eased in the near future, thanks to the latest robotic and imaging technologies. VascuLogic, a start-up supported by the NSF Small Business Innovation Research program, is bringing to market a device that aims to make the blood collection process safer and more efficient. The technology uses infrared and ultrasound imaging to identify veins. A robotically controlled needle is then guided into the targeted vein. The wh
