As a medical workers, you depend on vein finders to make your insertion job easier.Discover the best vein

finder lights and learn how they work – all right here.

The Vein Finder employs two safe 850nm lasers: an invisible infrared and a visible red.

The two lasers work in tandem to provide a real-time image of the subcutaneous vasculature up to 10mm

deep & 2mm diameter.First, the hemoglobin in the blood absorbs the infrared light, so there is a reduced amount of light.

reflection from the veins.  Then, a custom detection system uses this change in reflection to determine vein

location and pattern, which it digitally projects on the surface of the skin.  Lastly, the red laser makes the

vein mapping visible to the clinician.The angle of projection to the skin is preferably 90 °.

Besides，We are preparing to develop a new type of device suitable for children. It is composed of three lamps, which can shine blood vessels through children's skin.

It’s a very small light and works best for babies or children under 2 years old or older adults with thin, frail skin.
