Basic Use and Operation 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 re exes can be inhibited or reduced by
disease, drugs, or other medical conditions. For patients who
might have inhibited or reduced bright light blink re exes, Ac-
cuVein recommends out tting 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 con rmed 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.
Con rm the Vein
After assessing the patient's vasculature, con rm 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
quali ed medical professionals and only in conjunction with
appropriate visual and tactile vein assessment techniques.
