AimVein Vein Finder

If you’re starting Venipuncture, it’s important to find a vein that can be accessed easily. For those of us who will need blood drawn at some point in our lives (and there are many), knowing where the best place on your body for this procedure would make everything much easier!

However, it’s not always as simple as just looking for a big, blue vein running close to the surface of the skin. The vein can sometimes be tricky to find.

This is where a vein finder comes in handy! A vein finder is a small, handheld device that uses infrared light to detect veins beneath the skin.

The device emits a beam of light that is absorbed more by oxygen-rich blood (veins) than by the surrounding tissue. This difference allows the veins to be seen clearly on the device’s screen, making them much easier to locate.

Though using a vein finder is pretty simple, yet if you’re a beginner, you might not be aware of some of the finer details. Here’s a quick guide on how to use a vein finder for venipuncture.

Using a Vein Finder for Venipuncture


Wash your hands and the area around where you’ll be puncturing the vein. You don’t want to introduce any bacteria into the vein.

If the person whose veins you’re looking for is awake, have them relax their muscles and make a fist a few times. This will help bring the veins to the surface.

Position the device:

Hold the vein finder about 2-4 inches away from the skin. You should be able to see the beam of light on the person’s skin.

Scan the area:

Slowly move the device across the area you’re scanning. The screen will show a real-time image of the veins beneath the surface of the person’s skin. When you find a vein that looks good, mark the area with a pen or marker.

Puncture the vein:

Once you’ve found a suitable vein, clean the area around it and insert the needle at a 45-degree angle to successfully puncture the vein. If you’re not sure how to do this, don’t worry! There are plenty of instructional videos and articles online that can help you out.

After you’ve punctured the vein, attach the tubing to the needle and proceed with drawing blood.

And that’s all there is to it! By following these simple steps, you’ll be able to locate a vein quickly and easily, making venipuncture much less daunting.

Keep in mind that it’s important to be gentle when using a vein finder. If you press too hard, it can cause bruising.

If you’re having trouble finding a vein, don’t hesitate to ask a medical professional for help. They will be able to locate a vein quickly and with minimal discomfort.

Now that you know how to use a vein finder, venipuncture will be a breeze!
