Tired of the nurse stabbing you because s/he can't find a vein? These new glasses by 2AI Labs may help. They have color filters designed to spot blood. The developers anticipate that medical professionals will use them in three ways:
– (i) a vein-finder, or oxygenation-isolator, that amplifies perception of oxygenation modulations under the skin (and eliminates perception of variations in the concentration of hemoglobin),
– (ii) a trauma-detector, or hemoglobin-concentration-isolator, that amplifies perception of hemoglobin concentrations under the skin (and eliminates perception of variations in oxygenation), and
– (iii) a general clinical enhancer, or oxygenation-amplifier, that combines the best features of the first two; it eliminates neither signal (i.e., it retains perception of both variation in Hemoglobin oxygenation and concentration), and only amplifies perception of oxygenation.
