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.

37. A miniature vein enhancer comprising a first source of laser light, a second source of laser light, a polarizing element that polarizes said first source of polarizing light to a first orientation as said laser light from said first source passes through said polarizing element and said laser light from said second source of laser light reflecting off said polarizing element at a second polarized angle, laser light from said first and second sources being caused to become coaxial by said polarizing element thereby creating a pattern of light on a target area, such pattern of light on said target area creating a contrast between a blood vessel and the surrounding skin area.
- 38. The miniature vein enhancer comprising a plurality of sources of laser light, a movable mirror that is movable in a single axis that receives beams of laser light from said source of laser light, said mirror transmitting said beams of laser light onto a target area as said mirror moves thereby creating a pattern of light on said target area such that there is contrast between a blood vessel and the surrounding skin area.
- 45. A miniature vein enhancer comprising a plurality of sources of LED light, a movable mirror that is movable in a single axis that receives beams of LED light from said sources of LED light, said mirror transmitting said beams of LED light onto a target area as said mirror moves thereby creating a pattern of light on said target area such that there is contrast between a blood vessel and the surrounding skin area.

132. A miniature vein enhancer comprising a miniature projection head said miniature projection head comprising:
-
a source of laser light a movable mirror that receives a beam of laser light from said source of laser light, said mirror transmitting said beam of laser light onto a target area as said mirror moves thereby creating a pattern of light on said target area such that there is contrast between a blood vessel and the surrounding skin area. - View Dependent Claims (133, 134, 135, 136)
