The AV400 operates by using infrared light to detect veins be-
neath the skin, then projecting the position of the veins on the
skin surface directly above the veins. Qualified medical per-
sonnel can observe the vasculature as displayed to assist them
in finding a vein of the right size and position for venipuncture
and other medical procedures requiring the location of super-
ficial veins. No training is required to operate the AV400.
The AV400 only shows superficial vasculature. The maximum
depth that veins are displayed varies by patient. In addition,
some patients' veins or a portion of their veins might not be
displayed well or at all. Causes for less than optimal or lack of
vein display include, but are not limited to, vein depth, skin
conditions (e.g., eczema, tattoos), hair, scarring or other high-
ly contoured skin surface, and adipose (fatty) tissue.
Basic Use and Operation
Product Description
When held directly overhead, the AV400 accurately locates
the center of a vein. Increasing the displacement from direct-
ly overhead results in an offset in the displayed vein position.
Width of displayed vein may differ from the actual width de-
pending on patient to patient differences and vein width. The
center line of the vein is accurate when the device is being
used correctly and should always be used as the target when
performing venipuncture or other medical procedures.
The AV400 requires no routine or preventative maintenance.
The AV400 is portable internally powered by battery and ap-
proved for continuous operation. The AV400 is considered a
Type B applied part and is not protected by ingress of water.
