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: A vein imager includes: a housing with first and second portions respectively proximate to first and second ends of the imager; a first light source that emits a first wavelength; an optical detector responsive to the first wavelength and which converts a received vein image into a signal; a second light source that emits a second wavelength; one or more buttons protruding from the housing; and at least one exit opening in the housing for emission of light from the light sources. The first housing portion houses the light sources, the optical detectors, and includes the exit opening. The second housing portion, which houses a battery, is narrower than the first portion to be hand-holdable permitting single-handed lifting and use of the imager, which single-hand lifting and use does not cover the exit opening, and simultaneously permits actuation of the one or more buttons while holding the second housing portion.

Abstract: A fluorescence imaging device detects fluorescence in parts of the visible and invisible spectrum, and projects the fluorescence image directly on the human body, as well as on a monitor, with improved sensitivity, video frame rate and depth of focus, and enhanced capabilities of detecting distribution and properties of multiple fluorophores. Direct projection of three-dimensional visible representations of florescence on three-dimensional body areas advantageously permits viewing of it during surgical procedures, including during cancer removal, reconstructive surgery and wound care, etc. A NIR laser and a human visible laser (HVL) are aligned coaxially and scanned over the operating field of view. When the NIR laser passes over the area where the florescent dye is present, it energizes the dye which emits at a shifted NIR frequency detected by a photo diode. The HVL is turned on when emission is detected, providing visual indication of those positions.

Abstract: A portable hand-held miniature vein enhancer comprises: a housing, laser, one or more mirrors, mirror drive system, and sensor to determine a distance to the target. The laser emits a beam of light at a selective wavelength that images subcutaneous veins through differential absorption and reflection. The mirror(s) receive the beam of light and create a spot of light on the target, and when driven by the mirror drive system to oscillate, the spot is scanned to form a two-dimensionally shaped pattern of light. The scanned spot of light moves according to a range of angular positions of the mirror(s). When the distance to the target is at or below a threshold distance, the range of angular positions is set to a maximum, producing the largest scan pattern. When the distance increases beyond the threshold, the range of angular positions is reduced proportional to the increased distance.

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 be 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 three dimensional imaging system includes a first laser emitting light at a first wavelength, and a scanner for scanning the laser light in a pattern on the target area. A photo detector receives light reflected from the target area as a contrasted vein image, resulting from differential absorption and reflection therein of the first wavelength of light. The intensity of the first laser is incrementally increased, and the photo detector thereby receives a plurality of contrasted vein images, each being at incrementally distinct depths beneath the target skin surface. Image processing is performed on the plurality of vein images to successively layer the veins in the images according to their depth, to create a single processed vein image. A second laser emitting a second wavelength of light is used in combination with the scanner to project the processed vein image onto the target area to overlay the veins therein.
