    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.

    Abstract: The present invention is a Miniature Vein Enhancer that includes a Miniature Projection Head. The Miniature Projection Head may be operated in one of three modes, AFM, DBM, and RTM. The Miniature Projection Head of the present invention projects an image of the veins of a patient, which aids the practitioner in pinpointing a vein for an intravenous drip, blood test, and the like. The Miniature projection head may have a cavity for a power source or it may have a power source located in a body portion of the Miniature Vein Enhancer. The Miniature Vein Enhancer may he attached to one of several improved needle protectors, or the Miniature Vein Enhancer may be attached to a body similar to a flashlight for hand held use. The Miniature Vein Enhancer of the present invention may also be attached to a magnifying glass, a flat panel display, and the like.

    Abstract: A vein imaging device includes: a laser; one or more mirrors reflecting laser light onto a target creating a spot of light thereon; a mirror drive system; and drive circuit. The system drives the mirror(s) to oscillate about a corresponding fulcrum(s), to drive the spot upon the target in a pattern. Each oscillation includes: the spot driven in a first direction during a first part of the pattern, the mirror(s) decelerating to a full stop during a second part of the pattern, the mirror(s) subsequently accelerating in a reverse direction during a third part of the pattern, and the mirror(s) being driven to drive the spot in the reverse direction during a fourth part of the pattern. The drive circuit may reduce laser intensity when the spot is proximate to the full stop, to save power during unusable parts of the pattern because of the slowed mirror movement.
