Abstract: A vein imaging device includes: first and second lasers, a scanner, photo detector, memory, and microprocessor. The first laser emits a beam of light at a first wavelength, and the second laser emits a beam of visible light. The scanner is configured to scan the light from the first and second lasers onto the target in a pattern. The photo detector receives the first wavelength of light after being reflected from the target as a contrasted light/dark image of underlying veins, based on differential amounts of absorption and reflection by blood in the veins and surrounding tissue, and outputs a signal representative of the image. The memory receives and stores a sequential plurality of the contrasted images, and the microprocessor uses the stored plurality of the contrasted images to produce an averaged image with greater resolution, which is projected by the second laser onto the target using visible light.

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: It is known in the art to use an apparatus to enhance the visual appearance of the veins and arteries in a patient to facilitate insertion of needles into those veins and arteries. This application discloses a number of inventions that add additional data collection and presentation capabilities to a handheld vein enhancement apparatus and a set of processes for the collection of blood and the delivery of IV medicines that use the handheld device to mediate the process.

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 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.
