Vein finder devices are a medical technology that shows a clinician the location of peripheral veins. It’s also called vein illumination or vein visualization. Modern vein finder devices are hand-held and do not come in contact with the patient.
The most capable devices use Augmented Reality (AR) to project the vein pattern back onto the patient’s skin. AR is a technology that enhances what you see with the naked eye to give you more information about what you’re looking at.
All vein finder devices rely on the principle that the hemoglobin in the blood absorbs infrared light more than the surrounding tissues in the body. Infrared is invisible to the human eye, so the device needs to take the vein image that it detects and re-project it back onto the patient in a visible color to become visible to the clinician.
The NextVein Advantage
NextVein’s vein finder system uses advanced technology to provide clinicians with a detailed and accurate view of the veins in a patient’s body. Our system uses infrared light and an infrared-sensitive camera to detect the vein pattern, and then applies advanced algorithms to highlight the vein location.
A microprojector then projects the vein pattern onto the patient’s skin, aligning the image seen by the camera with the enhanced image from the projector. This ensures that the vein pattern is crisp, clear, and accurate. The camera and projector are fully digital, with no moving parts, making the system quick, easy, and reliable.
With NextVein, clinicians can quickly and confidently locate veins, providing their patients with the best possible care. Our system is portable, easy to use, and provides a detailed and accurate view of the veins, making it a valuable tool for any clinician who needs to visualize veins.
