Vein Scanner with User Interface for Controlling Imaging Parameters

摘要

A portable handheld vein-image-enhancing device broadly includes: a first laser emitting a beam of light at a first wavelength; a second laser emitting a beam of light at a second wavelength; a scanner to scan the beams of light onto the target surface; a photo detector to receive the reflected vein image and convert the image into a signal, for use by the second laser and scanner to project the image onto the target surface; and a user interface and electronic circuitry to permit adjustments to one or more of the following imaging parameters: a vein size parameter to set a vein size to be imaged by the device; a field of view size; a size for a field of high resolution for the projected image; a brightness of the projected image; and a laser output intensity parameter setting a depth of penetration by the first wavelength for the imaging.

主权项

1. A portable handheld vein-image-enhancing device, for use in selective imaging of subcutaneous veins of a target surface, said device comprising:
a first laser configured to emit a beam of light at a first wavelength; a second laser configured to emit a beam of light at a second wavelength being different than said first wavelength; a scanner configured to scan said beams of said first and second wavelengths of light onto the target surface; a photo detector configured to receive said first wavelength of light reflected from the target surface as a contrasted vein image formed by differential absorption and reflection by subcutaneous veins and surrounding tissue therein; said photo detector configured to convert said contrasted image into a signal; said second laser configured to receive said signal, and said second laser and said scanner thereby configured to project said contrasted vein image onto the target surface using said second wavelength of light, for the veins of said contrasted vein image to be projected onto the target surface directly over the imaged subcutaneous veins; and a user interface and electronic circuitry configured to permit adjustment of one or more imaging parameters for said selective imaging by said device.
