Abstract
A transillumination device having a yellow-orange light source, with LEDs having a wavelength in the range of 585-595 nm, preferably 590 nm, an amber light source with LEDs having a wavelength of light in the range of approximately 600-610 nm, preferably 605 nm, and a lime green LEDs light source having a wavelength in the range of approximately 535-545 nm, preferably 540 nm. Yellow-orange LED light sources have been found to be beneficial for transillumination of superficial veins, amber light sources have been found to be beneficial for transillumination of deeper veins and lime green light sources have been found to be beneficial for transillumination of arteries.
Claims2
A transillumination device comprising in combination:
- a housing having a first end, a second end, a top surface, and a bottom surface,
- a yellow-orange first light source, an amber second light source, and a lime green third light source, the first light source being composed of LEDs producing light having a wavelength in the range of from 585-595 nm for illumination of shallow veins, the second light source being composed of LEDs producing light having a wavelength in the range of approximately 600-610 nm for transillumination of deeper veins, and the third light source being composed of LEDs producing light having a wavelength in the range of approximately 535-545 nm for illumination of arteries,
- an on/off switch for turning the transillumination device on and off,
- a light control switch for switching between the first, second, and third light sources, and
- a power source contained within the housing for powering the first, second, and third light sources.
