Evaluation: Novarix IV-eye Near-Infrared Vein Finder
May 23, 2018 | Evaluations & Guidance
- The IV-eye uses near-infrared (NIR) light to identify and assess peripheral veins suitable for vascular access procedures such as blood sampling and IV infusion.
- The IV-eye enhances assessment of veins that are identified using conventional techniques of direct visualization and palpation, and is designed to detect and assesses additional veins that may be suitable for vascular access.
- The IV-eye is placed in contact with the patient's skin surface over the desired vascular access site. Once the appropriate vein is selected and marked, the IV-eye is removed and the procedure is performed.
- The IV-eye is not intended to locate veins on the head or neck, on limbs smaller than 30 mm (~1 in) wide, or in locations with thick hair or on broken or damaged skin.
- The IV-eye is a handheld device that is 11 × 5 × 5.5 cm (4.3 × 2 × 2.2 in) in size and weighs 0.185 kg (6.5 oz). It consists of:
- NIR LED light sources that project invisible, 850 nm wavelength NIR light into the patient's body. Two light sources are contained in each of the wings located on the sides of the device. The wings are flexible and attached to the main unit.
- A camera that captures the NIR data and a digital processor that uses the data to create the image of the underlying tissues and vascular structures that is shown on the LCD screen. The camera window is on the underside of the IV-eye, and the processor is in the device.
- An LCD screen, which is used to view the NIR images and device status. A 4.6 × 3.3 cm (1.8 × 1.3 in) transflective video display is located on the top of the device. It has an 80° viewing angle in all directions. A red line on the center of the display is used to align the device on displayed veins. Grayscale and color display modes are available and are selected based on user preference and patient characteristics. A battery status icon is on the display.
