In 2013 and 2014 two companies announced they had developed fully automated venipuncture devices that both located a proper vein and stuck the patient. In 2016 a third organization also announced that their group was developing a platform device that merged robotic phlebotomy with a centrifuge-based analyzer to obtain quantitative measurements of hematology. The authors have seen no reviews or evaluations of these devices in the scientific literature. In addition to cost of instrumentation, whether or not patients will trust an automated venipuncture device to put a needle in their arm questions their adoption. Two other automated venipuncture devices were announced, the Roblood and the BloodBot, but it appears research and development has been discontinued on both.
