Vein Finder

An infrared (IR) vein finder is a medical device used to visualize veins, making venipuncture (inserting a needle into a vein, typically to draw blood or administer medications) easier and more accurate. The device is particularly helpful for healthcare providers when dealing with patients who have difficult-to-locate veins, such as infants, elderly individuals, or obese patients

The hand-held infrared vein locator can be used in hospitals and aesthetic plastic surgery departments, and can also be used for venipuncture such as injection, physical examination, infusion, and blood collection for individuals or outpatients.

1. Infrared Light: Vein finders use infrared light, which penetrates the skin and is absorbed by the deoxygenated blood in veins. The absorbed light makes the veins appear darker compared to the surrounding tissue.
2. Visualization: Depending on the design, some vein finders project a map of the veins directly onto the skin, while others display the map on a screen.
   
   ● Advantages
   ① It can assist in evaluating the thickness, depth, straightness, length, bifurcation, venous valve and other detailed information of blood vessels..
   ② It can observe the filling degree of blood in the blood vessels, detect the state of blood flow, and judge whether there are abnormalities such as hematoma after intravenous injection
   ③ The direction of blood flow can be observed intuitively, and the velocity of blood flow and the filling degree of blood can be evaluated qualitatively
   ④ It can visually monitor the flow of the liquid in the blood vessels, and the medical staff can intuitively judge whether there is leakage of the liquid, especially in the monitoring of the tumor drug injection process. tissue damage
   ⑤ In the process of varicose veins, with the help of a vascular imaging device, the time to find blood vessels can be shortened and the accuracy of judgment can be improved
