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?
If 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.
How to Vein Finder Glasses Work?
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.
Now that we know how vein finder glasses work, let’s review the best available on the market.

#1. Hand Wash
#4. Disposable Gloves
#5. Preparation Pads
#6. Disposable Tourniquets
#7. Disposable Container
#8. Disinfectant Wipes
#9. Disposable Covers
Using the above vein finder accessories will ensure you are running a hygienic and safe practice. Moreover, you will be more confident in your ability to treat patients.
Patient Safety When Using Vein Finder Glasses
Before treating your patient, you should find out their history. For example:
- Is there any part of the body where the blood should not be drawn, perhaps because of an earlier surgery?
- Does their blood take time to clot, perhaps because they have hemophilia?
- Are they an MRSA carrier?
- Do they have a blood-borne disease such as hepatitis or HIV?
Here is a good video about cannulation:
Vein finder glasses are a worthy investment if you have frequent treatment to perform for someone like a hemophiliac or if venipuncture is a regular part of your job. The above are the best vein finder glasses on the market.
