Quote from Vein-Eye Brad
Just very excited from using this vein finder as we get a lot of older people in AZ with brown (tan or Hispanic to very dark skin) and its very hard to find viable veins the first time.
Where did you get a chance to use one of Near Infrared's vein camera?
We got an early proto-type to try and they are not even for sale yet...
Near infrared has been around for many years and has been produced by many companies in many different forms. They all have the same exact issues, only about 0.5cm in depth, rely upon infrared/near infrared radiation, and only represent a 2D picture of the vessel. There is very little practical difference between near infrared and shining a bright flashlight through the skin.
Until these devices reach a price in the several hundred dollar range they are simply outclassed by even the most rudimentary of ultrasound machines. US allows you to assess the vessel, nerves, adipose, muscle, and bone tissue up to several cm below the skin with a lateral and longitudinal view.
Dollar for dollar, near infrared imagers are simply not practical. Its like selling a bicycle for the same cost of a car.
