Function introduction-vein depth detection mode

Vein Depth Detection mode is our unique feature in the world. It can help nurses choose the right angle to insert the needle when performing venipuncture. In addition, it can tell us if there is a vessel or not.

Under the depth detection mode, the red cross mark will be shown on the central of projection zone. When the green light is beside the red cross mark, it indicates that there is a vessel. We can tell the depth of vessels from shallow to deep with 1, 2, 3 green light separately
. If it shows one green light, which means the vein depth is 0~2mm under the skin. If there are two green lights beside the red cross, which indicates the vein depth is 2~4mm. Once there are three green lights beside the red cross, which means the vein depth is ≥4mm.
