Publication number: 20210338151Abstract: 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.

Publication number: 20210275757Abstract: A vein imager includes: a laser emitting a light beam in a first optical path; and scanner directing the beam to form a spot of light on the target, and scanning the beam to move the spot rapidly on the target. An optical element bounces the beam of light from the first optical path onto a second optical path, directing the beam at the scanner. The scanner directs an image portion, received from the target, along the second optical path toward the photodiode, the image portion being an afterglow formed by differential reflection and absorption of the scanned spot by surrounding tissue and blood vessels. A lens is positioned/configured to limit a size of the photodiode FOV to a portion of the target surface, which size encompasses only the spot size and a portion of the afterglow. The limited photodiode FOV thus moves synchronously with the scanned spot.Type: ApplicationFiled: April 6, 2021Publication date: September 9, 2021Applicant: AccuVein Inc.Inventors: Fred Wood, Vincent Luciano, Ron Goldman

Patent number: 11109806Abstract: 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.Type: GrantFiled: August 29, 2017Date of Patent: September 7, 2021Assignee: AccuVein, Inc.Inventors: Ron Goldman, Fred Wood, Stephen P.

Patent number: 11051697Abstract: An apparatus for capturing a multispectral image of an object is described. The apparatus includes one or more means for transmitting a beam of laser light at a first wavelength and a beam of laser light at one or more additional wavelengths different from the first wavelength. There is a means for causing the beams of laser light to travel in a coaxial path and a moving mirror. The beams of light bounce off the mirror thereby producing a two dimensional projection pattern. This pattern travels from the mirror along a first path to an object and wherein some of the laser light penetrates the object and travels to an internal structure of the object. The reflection of the laser light returns to a photo detector along a path different from said first path.Type: GrantFiled: October 15, 2013Date of Patent: July 6, 2021Assignee: AccuVein, Inc.Inventors: Fred Wood, Ron Goldman, Vincent Luciano

Publication number: 20200100681Abstract: 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 energies 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.Type: ApplicationFiled: December 3, 2019Publication date: April 2, 2020Applicant: ACCUVEIN.

Publication number: 20200078534Abstract: 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.Type: ApplicationFiled: October 8, 2019Publication date: March 12, 2020Applicant: AccuVein Inc.Inventors: Fred Wood, Vincent Luciano, Ron Goldman
