Advancements in medical tech are outstanding, but I think that this simple device could save many a few painful jabs while their doctors fiddle around trying to find a vein. Unfortunately though, given the limited availability of resources in an over stretched public health sector the likelihood of uptake is limited. Perhaps its application could be generalised to angiographic investigations to rapidly evaluate vascular supply to end organs, limiting the the time spent on the operating table and the cost of surgical procedures.
