As the name suggests, vein finders are devices that are used to locate veins. Vein finders emit a low-level infrared light that is absorbed more by oxygenated hemoglobin in the blood than by the surrounding tissue.
This allows the user to see a real-time image of the vasculature (veins and arteries) beneath the skin.
Vein finders are commonly used in healthcare settings to help with intravenous (IV) insertion, blood draws, and other procedures that require access to a vein.
While vein finders can be very helpful and can locate even the smallest of veins, there are several factors that can affect their accuracy and they may not be able to locate veins of all types. Some factors that may affect their accuracy include:
Skin tone: Darker skin tones can make it more difficult to see the vein beneath the surface, however certain brands of vein finders can manage to locate veins under dark skin tone.
Dehydration: Dehydration can cause the veins to contract, making them harder to locate, even for the vein finders, but it’s not impossible though, and using a reliable vein finder might help.
Age: Younger patients tend to have larger, more visible veins than older patients.
Obesity: Excess body fat can make it more difficult to see the veins.
Vein finders are not always 100% accurate, but they can be a helpful tool in locating veins, especially in difficult-to-access areas. If you are having difficulty finding a vein, talk to your healthcare provider about other options, such as ultrasound guidance or palpation.
Which Veins Can a Vein Finder Find?
Not all veins can be found using a vein finder. The most commonly sought-after veins are the superficial veins, which are located close to the surface of the skin. These include the
- Cephalic vein
- Basilic vein
- Median cubital vein
The cephalic vein is often used for IV insertion in the arm, while the basilic vein is used for IV insertion in the hand. The median cubital vein is located in the elbow and is often used for blood draws.
Other veins, such as the deep veins, are located deeper below the surface of the skin and are much harder to locate using a vein finder, yet some high-end and reliable vein finders can still manage to do so.
How to Use a Vein Finder to Locate Veins of All Types
Using a vein finder is not a big deal at all. You just have to follow these simple steps:
- Clean the area where you will be using the vein finder with an alcohol swab.
- Turn on the vein finder and hold it approximately 1-2 inches away from the skin.
- Slowly move the device around the area until you see a clear image of the veins.
- Once you have located the vein, you can insert the needle into the vein.
Now that you know how to use a vein finder, it’s time to learn about the different types of vein finders that are available on the market.
