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 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:
A vein imager includes: two photodetectors, a first and second lasers configured to respectively emit an infrared beam of light and a human-visible beam of light; a combiner to coaxially align the two beams; and a scanner that scans the coaxial beam in a pattern and onto a skin surface of a patient. The first photodetector receives the infrared wavelength reflected from the patient as a contrasted image of subcutaneous veins, and surface reflection noise due to skin surface topology, and outputs a first signal representing that contrasted image of subcutaneous veins and noise due to skin surface topology. The second photo detector receives the human-visible wavelength reflected from the skin surface and outputs a second signal representing a contrasted image of the topology. The second signal is subtracted from the first signal to remove the noise, permitting projection of a surface-noise-free vein image onto the skin surface.
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:
A laser based vascular illumination system utilizing a FPGA for detecting vascular positions, processing an image of such vasculature positions, and projecting the image thereof onto the body of a patient.
Abstract:
An apparatus and method for insuring the proper alignment of a detected vein pattern and a projected vein pattern are disclosed. The apparatus enhances the visual appearance of veins so that an error that can lead to improper patient care or injury can be avoided.

Abstract:
The present invention is a Miniature Vein Enhancer, for use in imaging the subcutaneous veins of a target area of a patient by a practitioner. The miniature vein enhancer includes a Miniature Projection Head that is secured to a tourniquet, where the tourniquet may be mounted to the bicep of a patient. The Miniature Projection Head includes a housing, and apparatus that images subcutaneous veins of the target area, and projects the image(s) of the veins onto the target area to overlie the subcutaneous veins, which aids the practitioner in pinpointing a vein location for a venipuncture procedure such as an intravenous drip, blood test, and the like.
