Vein Finder Glasses Review

how do vein finders work

One of the challenges that nurses may face from time to time is locating veins in some patients. For example, finding the veins of the elderly, children, or patients with dark skin can sometimes be difficult for nurses and paramedics doing cannulation and venipuncture. If you are not using a vein finder, most of your patients will need an additional stick, and this can be traumatic for them as well as you.

Vein finders can help you find the right veins quickly. When you use these devices you will reduce wastage of PICC, syringes, needles and midline trays on stick after stick. These venipuncture devices are non-invasive and use light to help you see the veins in the subcutaneous tissues.

Types of Vein Finders

There are two types of vein finders; active and passive devices.

Active devices use infrared and red light to shine the hemoglobin in the blood. On the other hand, passive vein finders change the amount of visible light entering your eye so that you can see the veins easily.

Majority of the recommended vein finders for nurses are the active devices.

How Do Vein Finders Work?

how do vein finders workIf you shine a flashlight through places with light tissue on your hand, e.g., the palms, you are likely to see the veins. The light from the flashlight cannot, however, penetrate thicker muscles to show the veins.

A vein finder works in a similar way to a flashlight in that it shines an infrared light on your muscles to reveal the veins. The infrared light can, however, penetrate a few millimeters into your muscles to show the veins.

When infrared light shines on your muscles, it is absorbed by the hemoglobin in the blood. In turn, the light “highlights” the superficial vasculature. The veins will be seen even if a person has thick muscles or dark skin.

Vein finder glasses are passive vein finding devices that look like the conventional sunglasses. These devices alter the color of visible light to enable you to see veins more easily. For best results, the glasses have to be used with powerful illumination.
