New Smart Glasses Allow Nurses To See Veins Through Skin
Lucas123 writes "Epson and Evena Medical today unveiled a new smart-glass technology that allows nurses to see 'through' a patient's skin to the vasculature beneath in order to make intravenous placement easier. The Eyes-On Glasses System is based on Epson's Moverio Smart Glasses Technology, an Android-based, see-through wearable display launched earlier this year that allows users to interact with apps and games. The glasses use near-infrared light to highlight deoxygenated hemoglobin in a patient's veins and capture the images with two stereoscopic cameras. The cameras then project the vein images onto the see-through glass screens. The glasses can store the images and video and transfer them wirelessly to a patient's electronic health record, and they also come with dual built-in speakers for video conferencing."
...that they don't have to play "Go Fish" in my arm every time I get an IV in, I'm all for it, unintended consequences be damned.
Had to go into the hospital for the first time in ages the other day, and it took about five or six sticks -- including the kind where you can see them feeling around for anything once the needle's already in you -- before they hit the vein. And I'm skinny, as well, at least in the places where they stick me. Can't begin to imagine what it's like if your veins are invisible.
We already have technology that does this. We have hand-held devices that shine near-infrared light through the skin and make the veins show up just fine.
They have significant problems, which this system shares. Most importantly, they show *all* veins, including all the ones which can't be cannulated because they are too small, too fragile, or too badly scarred. You have to palpate (feel) the vein to assess whether it's suitable, and if you can palpate it, you don't need to see it at all.
Also, they really only work at all on caucasian skin.
Further, this system is kind of ridiculously expensive. Even though the prices have dropped on commodity displays, microprocessors, 3G and wifi, and all those bells and whistles, it's still a complex piece of gear. We may as well pay for a bedside ultrasound which costs no more, is more precise, and is useful for a lot more than just IV starts.
