How does a vein finder work? 3 Basic Things

How does the vein finder work?

Have you ever wondered how the vein finder works and what the device is for? It’s not that complex.

First, let me introduce the vein finder to you on short notice.

A vein finder is a medical device based on the principle of the different light absorption rates between the blood and the surrounding tissue.

Therefore, it can display the veins in real-time so that medical staff such as nurses and doctors can locate the vein and perform all kinds of procedures more efficiently and more accessible. Let’s see what that means and some basic things you need to know.

1. What is Vein Finder, and how does a vein finder work?

So how exactly does the vein finder work? Not all devices use the same technology, but the underlying principle is the same.

The fundamental principle of the device is that the hemoglobin in the blood has a different light absorption rate than the surrounding tissue. The device then uses this difference to identify the veins. Projected near-infrared (NIR) light is absorbed by blood and reflected by surrounding tissue.

This is not complex; here is a picture that may help you understand.

In this image, we can see that the hemoglobin in the blood absorbs most of the light, so there is a reduced amount of light reflection from the veins.

For the surrounding tissue, we can see in this image the surrounding tissue doesn’t absorb light as much. Instead of drinking, the surrounding tissue reflects the light.

The information is then digitally captured, processed, and projected in real-time directly onto the skin’s surface. Provides an accurate, real-time image of the patient’s blood pattern.

What is vein visualization?

Vein visualization is an innovative technology that helps healthcare professionals find the best veins for IV starts and blood draws. Also known as vein mapping, this technology creates a real-time visual “map” of the veins on the skin’s surface.

VF30 Vein Finder

The VF30 can digitally display a map of veins on the skin surface in real-time, helping healthcare professionals verify vein patency and avoid valves or bifurcations. And patients.

1. What can vein finders do? Venipuncture anywhere.

As we know, the vein finder can help our medical staff locate the vein, so what is the benefit of that? I agree. As long as a venipuncture is in progress, the vein finder can help.

IV access is the number one vein finder app. Establishing intravenous (IV) access is an essential skill that challenges many medical professionals. This also causes unnecessary pain for patients, we have all been through the fear that the nurse will inject the needle, but there is no reflux of blood, so we have to do it again.

And for patients with difficult venous access. Patients who are elderly, obese, dark-skinned, hypovolaemic, have a history of intravenous drug use or have chronic illness present unique problems in finding a suitable vein for venipuncture.

1. Blood draw procedure

Although there is no substitute for the expertise of a trained professional, the vein finder can help simplify the task of locating the needle placement site.

Since the principle of vein visualization will not be limited to different body parts, it can be used for blood draw procedures and works well for the median cubital vein as it is a massive vessel.

For the middle cubital vein, the vein finder can always show them clearly. The vein finder can significantly help those who could be more experienced.

Here is a GIF of the blood draw procedure.

1. Cosmetic procedures

One of the particular uses of the vein finder is cosmetic procedures; some people may not know that when performing cosmetic procedures like injecting fillers, especially in nasolabial folds and lip tears, doctors should avoid veins once accidentally inject the stuffing into the veins, not only your face will be ruined, as well as your life and the doctor’s career.

This is the most severe side effect of the wrong vein location; here is a picture.

1. Many other applications.

Many other vein finder apps like infusion centers, vascular procedures, etc.

Here is an article investigating patient characteristics that correlate with identifying iv cannulation sites with normal vision. We evaluated a new infrared vein finding (VF) technology device to identify iv cannulation sites.

3. There are so many kinds of vein finders on the market.

There are three main types of vein finders on the market,

• Infrared Light Projected Vein Finder
• Infrared Light Screen Viewer Vein Finder
• Transmission LED Vein Finder

We are going to go through these vein finders one by one.

1) Infrared Light Projected Vein Finder

Infrared light projected vein finder is now the most popular type, and it is primarily lightweight and handy. But what makes the Infrared Projected Vein Finder so popular is that the device can project the images of the veins directly onto the surface of the patient’s skin. It is very convenient for daily use. And most of them come with a kickstand/stand, so you won’t need another person to hold the device; it can be placed on a desk for everyday use.

Like VF Vein Finder, VeinSight, Accuvein, and Veinviewer.

2) Infrared Light Screen Viewer Vein Finder

Vein Finder Infrared Light Indicator means that when the device captures the vein images, it displays them on a screen. The device always comes with a probe and a display.

3) LED vein transmitter

This type of vein finder, also called Portable Vein Finder, always comes in a small size. Use lots of bright light. Gently depressing the illuminator stretches the skin and pools the vein to facilitate needle insertion.

Top 5 Infrared Vein Finders on Amazon-2023

Vein identifiers are very popular in many markets because they can help our medical professionals, such as nurses, doctors, phlebotomists, and patients.

It can save time, reduce waste, and, most importantly, it can release pain for patients, in addition to freeing yourself anxious from the medical professional. It was most necessary for patients with hard-to-find veins—especially the elderly, the dark-skinned, children, and babies.

We have been working for many days of research and found the 5 Best Selling Infrared Vein Finder on Amazon. This article has everything you want to know about them, why is it the best? How much is it? And how can you buy it?

1. Benefits of vein finder

Only some have veins that are big and easy to find. Some people’s superficial veins are small, so look for one large enough to accept the catheter or needle. Ultrasound machines can be helpful for this, but they are only sometimes available.

Any medical professional who performs venipuncture and cannulation knows that some people have veins that are difficult to detect.

Statistics published by hospitals show that without a venous lumen, at least 25% of all patients go through more staves, which is painful, stressful, and reduces the procedure’s safety.

Here are the apparent benefits of using a simple tool like the infrared finder:

• Proven greater visibility of the veins.
• The infrared vein light device is non-invasive and painless.
• Avoid unnecessary pain and stress for the patient.
• Reduced waste of needles, syringes, PICCs, and midline trays.
• Save time.

1. How does a vein finder work?

Vein imaging technology uses safe, non-invasive infrared light to project a processed image of the patient’s veins onto the back of their hand. The Vein Finder works because the hemoglobin in the blood absorbs infrared light more than the surrounding tissues and muscles.
