What is a Vein Finder?


A vein finder is a handheld device that helps locate and display veins and project a patient's vein map onto the surface of the skin. It can improve the success rate of puncture and reduce pain and trauma for patients.

The vein finder is divided into three types according to the principle of use:

1) Infrared Vein Finder

2) LED Light Vein Finder

3) Laser Vein Finder

Infrared Vein Finder

Infrared vein finders are optical devices that construct an image and superimpose it onto the viewing area by using the behavior of infrared light. It is the most used vein finder light you can find out there.
how to find a vein to draw blood
The basic principle of Infrared vein finder is that hemoglobin in blood has a different light absorption rate than surrounding tissue. So the device uses this difference to identify veins. The projected near-infrared (NIR) light is absorbed by the blood and reflected by surrounding tissue.

Lite 2.0 Vein Finder uses vein visualization technology that shines an infrared light on the patients' skin. The hemoglobin (an oxygen-carrying protein) in the patient's blood absorbs the light, forming a vein pattern visible on the skin's surface. Following processing, Vein Finder will project the vein image on the skin's surface at the precise position. This Near-infrared vein finder is currently the most effective and safest vein finding device.

In addition to Lite 2.0 Vein finder, Accuvein and Veinviewer are also popular infrared vein finders.

Red LED Light Vein Finder


Red Light Vein Finder usually uses a red LED light to illuminate the skin and find veins. To use, the nurse slowly shines light on the skin. Against the red light, the veins appear as shadows.

The Illumivein vein finder is a flashlight with a red LED light, and while it can help people find veins, it is only effective in dark rooms and light. To use, you must gently press the skin with your hand and slowly move the device from side to side. Veins will appear as shadows or dark lines that will appear on the periphery of the device, glowing red. When looking for a vein, the device must be in contact with the skin.

Veinlite vein finder also uses LED lights to illuminate and locate veins. Their unique wide C-shaped design stretches the skin for easier needle insertion and stops the vein from rolling during entry. Veinlite LED+ ® features 28 bright light emitting diodes (LEDs). The 22 bright orange and 6 deep red LEDs can be operated together or individually and are suitable for patients of all ages and skin tones.

iism vein probe is a mobile and portable vein finder. It can detect the exact location of veins in real time and is suitable for patients regardless of skin color and age, and can be used for various injection treatments.

What color light is best to see veins?

Blood color is red, and a surgeon will tell you that our veins are also crimson; they only appear blue when we look at them through our skin. But why is that?

The answer depends on several factors, including how your eyes interpret color, how light reacts when it comes into touch with your body, and the unique characteristics of blood. When the light of a particular color strikes our eyes - either directly from a light source or reflected from a surface - we see it as that color. However, to understand why our veins seem blue, we will only look at the red and blue ends of the spectrum.

● Red light has a large wavelength, which means it is less likely to be deflected by materials and may pass through more readily. Red vein finder light may penetrate rather effectively through the skin and bodily tissues, reaching as far as 5-10mm below the skin, where numerous veins are located. The red vein finder light is absorbed by hemoglobin as it reaches the veins. You may show this to yourself. When you shine a light (red light) on your arm, you will see some red light reflected on you, as well as black lines where the veins are, since the hemoglobin absorbs the red vein finder light. This phenomenon is utilized to assist medical workers in finding veins to collect blood by flashing red and occasionally infrared vein finder light on the arm.

● Blue light has a shorter wavelength and is more easily dispersed or deflected than red light. Because it is quickly distributed, it does not enter as deeply into the skin. Blue light is typically reflected when it strikes the skin. When you flash a blue light on your skin, all you see is blue skin, with few veins visible. You may have seen blue light used to deter intravenous drug usage in places such as public restrooms. Surprisingly, the impact varies depending on the depth of the vein as well as the thickness of the vein. The capillary bed and tiny veins near the surface will not show blue. Blue veins are more visible in persons with ashen skin, which may have originated the term "blue blood" for European nobility in the nineteenth century. Because these guys were not browned from physical labor, their veins appear blue under the skin.

Lite 2.0 Vein Finder available in five different colors. Depending on your skin tone, different colors will be introduced to the skin so that the medical practitioner can easily penetrate the vein.
