Abstract

The transillumination device has an orange light, in the range of 580-620 nm. Orange light has been found to be beneficial for superficial veins. Red light is used for deeper veins and darker skin. The transillumination device may have a single light source able to change colors. Two different light sources, each having a different color or different transillumination devices, each having a different color, may be used for diagnostic purposes.

Claims

1. A side transillumination device comprising:

a hand held medical device having a housing,

a light emitting diode retained by said housing for vein imaging, said light emitting diode emitting an orange light from said side transillumination device, said orange light having a wavelength of only between 580 and 600 nm.

2. The side transillumination device of claim 1, further comprising

a circular area of illumination extending from said housing,

a viewing area formed between said circular area of illumination.

3. The side transillumination device of claim 1, further comprising

a light source emitting a red light.

4. The side transillumination device in accordance with claim 1, further having a means for directing said orange light at an angle toward a patient'"'"'s skin.

5. A method of vein imaging, comprising:

providing a side transillumination device including a light emitting diode,

placing said light emitting diode of said side transillumination device proximate to the patient'"'"'s skin, said light emitting diode emitting an orange light having a wavelength of only between 580 and 600 nm;

imaging a vein of the patient with said orange light for diagnostic purposes.

6. The method of claim 5, further comprising

using a red light to view deeper veins.

7. The method in accordance with claim 5, further including the step of:

directing said orange light at an angle toward the patient'"'"'s skin.
