Vein Finder / survival+emergency

Many times, it is hard for a nurse to search for patient's vein while giving patients injections. Especially with children and obese people. One mistake from the nurse’s operation will cause pain for the patient. The Vein Detector will be worn on the nurse's thumb to help the in searching the vein in a quick and precise way. Infrared detector scans the patient's hand then put the picture on the viewing screen of the Vein Detector.
