Near-infrared vein finder
Near-infrared Vein Finder
The Near-infrared Vein Finder (pronunciation: /nɪər-ɪnˈfrɑːrɛd veɪn faɪndər/) is a medical device used to locate and visualize veins beneath the skin's surface. This technology is particularly useful in medical procedures that require venipuncture, such as blood draws or the insertion of intravenous (IV) lines.
Etymology
The term "Near-infrared Vein Finder" is derived from the technology it uses. "Near-infrared" refers to the specific wavelength of light used by the device, which is in the near-infrared spectrum. "Vein Finder" refers to the device's primary function, which is to locate veins beneath the skin.
Function
The Near-infrared Vein Finder works by emitting a near-infrared light onto the skin. This light is absorbed by the blood in the veins, but reflected by the surrounding tissue. The device then uses this difference in absorption and reflection to create an image of the veins.
Related Terms
- Venipuncture: The process of puncturing a vein, typically for the purpose of drawing blood or inserting an IV line.
- Intravenous (IV): Referring to something that is done or existing within a vein, such as the administration of medication or fluids.
- Phlebotomy: The practice of drawing blood from patients and taking the blood specimens to the laboratory to prepare for testing.
Usage
Near-infrared Vein Finders are used in a variety of medical settings, including hospitals, clinics, and laboratories. They are particularly useful in situations where veins are difficult to locate by traditional methods, such as in patients with small or deep veins, or in patients with dark skin.
