Vein scanner with user interface
First Claim
1. A vein imaging apparatus, for use in imaging veins of a patient and for locating the veins for a medical practitioner by projecting the image onto the patient'"'"'s skin surface, said vein imaging apparatus comprising:
- a first laser configured to emit at least a first wavelength of light;
one or more photodiodes, said one or more photodiodes each configured to be responsive to said at least a first wavelength of light, to thereby receive a contrasted vein image formed by reflected light at said first wavelength, and to convert said image into a signal;
a second laser configured to emit at least a second wavelength of light, being different than said at least a first wavelength of light;
a user interface board comprising;
electronic circuitry;
a display screen;
one or more push buttons;
a memory; and
firmware, said firmware configured to display a scrollable menu screen list of two or more configuration settings, and the parameters for each of said two or more configuration settings, on said display screen, said firmware further configured to permit actuation of said one or more buttons to select and to modify any of said two or more configuration settings to be the default setting for said apparatus, and to permit said selected default settings to be stored in said memory, said two or more configuration settings comprising a plurality of vein visualization settings; and
wherein said electronic circuitry is configured to receive said signal from said one or more photodiodes and to output said signal to said second laser, said electronic circuitry configured to cause said second laser to use said signal to emit said at least a second wavelength of light to project said vein image in accordance with said selected vein visualization setting, being optimized for the skin surface.

Abstract
A portable vein viewer apparatus may be battery powered and hand-held to reveal patient vasculature information to aid in venipuncture processes. The apparatus comprises a first laser diode emitting infrared light, and a second laser diode emitting only visible wavelengths, wherein vasculature absorbs a portion of the infrared light causing reflection of a contrasted infrared image. A pair of silicon PIN photodiodes, responsive to the contrasted infrared image, causes transmission of a corresponding signal. The signal is processed through circuitry to amplify, sum, and filter the outputted signals, and with the use of an image processing algorithm, the contrasted image is projected onto the patient'"'"'s skin surface using the second laser diode. Revealed information may comprise vein location, depth, diameter, and degree of certainty of vein locations. Projection of vein images may be a positive or a negative image. Venipuncture needles may be coated to provide visibility in projected images.
