2.2 Product Descriptions
The VS400 vein finder detects veins beneath the skin by
using infrared light, then projecting the image of the veins on
the skin surface directly above the veins.

vasculature to find a vein of the right size and the location of
superficial veins for venipuncture and other medical
procedures.

The maximum depth of displayed veins varies depending on
the patients.
The causes for the different depths of displayinclude, but are
not limited to, vein depth, skin conditions (e.g. eczema,
tattoos), hair, scarring or otherhighly contoured skin surface,
and adipose (fatty) tissue.
When held directly overhead, the VS400 vein finder
accurately locates the center of a vein.
The width of displayed veins may differ from the actual
width, due to the physical differences of patients and the
width of veins. But the center line of the vein is accurate.
The VS400 vein finder is internally powered by battery and
approved for continuous operation.
