Patent ID: 8150500

Claim:
A miniature vein enhancer for enhancing a target area on a patient comprising: a first laser configured to selectively transmit light at a first wavelength within the infrared spectrum; a MEMS scanner configured to cause said first wavelength of laser light to be transmitted in a raster pattern onto said target area; a photodectector configured to be responsive to said first wavelength of light, said photodectector further configured to receive said first wavelength of light reflected off said target area, said reflected light comprising a contrasted image being formed by at least a selective portion of said transmitted light of said first laser being reflected from said target area, and by a remaining portion of said transmitted laser light of said first laser being absorbed by subcutaneous veins of said target area; a needle configured to be responsive to said first wavelength of light to be visible within said contrasted image; a vial holder secured to said miniature vein enhancer and configured to receive said needle; a second laser configured to selectively transmit light at a second wavelength within the visible spectrum, said second laser projecting said contrasted image onto said target area to reveal vein locations therein and a position of said needle in relation thereto.
