Basic Use and Operation

Operating the AV400 (continued)

Inverse setting:

The inverse setting inverts the dark (shadow) and light (red)

projection areas of the AV400 such that the veins can be de-

picted by either light or dark. Changing the inverse setting

may improve vein visibility and eye comfort level. AccuVein

recommends reversing the vein display to show light veins in

cases where veins are very small. When operating the device

outdoors or in bright surroundings, use the dark veins settings

to enhance visibility.

WARNING: Do not shine vein display light in eyes.

WARNING: Blink reflexes can be inhibited or reduced by

disease, drugs, or other medical conditions. For patients who

might have inhibited or reduced bright light blink reflexes, Ac-

cuVein recommends outfitting the patient with a protective

eye shield. A protective eye shield capable of blocking 642 nm

and 785/830 nm should be used.

Assess the Vasculature

While the vein display light is on, shine the AV400 over the pa-

tient's skin. You can do this before palpation, scanning quickly

over the skin to help narrow down possible locations, or after

palpation has confirmed vein location and suitability.

You can then often see veins better by rotating the AV400

slightly on its axis, and moving the device closer to or further

away from the skin.

Confirm the Vein

After assessing the patient's vasculature, confirm the site for

your procedure by verifying the location and suitability of

the vein using normal medical techniques and good medi-

cal judgment, such as vein visualization, palpation, and oth-

er medical techniques.

If performing venipuncture

If you are performing venipuncture, you may use an AccuVein

hands-free accessory so both your hands remain free to per-

form the procedure. You can also hand the AV400 to an assis-

tant during the procedure. The AV400 should be used only by

qualified medical professionals and only in conjunction with

appropriate visual and tactile vein assessment techniques.
