Color: Black Size: 95x29mm One of the most challenging aspects of blood collection is locating a suitable vein. Some patients are considered difficult due to small or deep veins, making it hard for healthcare professionals to identify an appropriate site quickly and efficiently. Multiple needle insertion attempts can cause discomfort and may affect patient confidence in the practitioner. This device is designed to assist in visualizing veins, making it useful for small clinics, medical facilities, and trained professionals. It helps support vein location with minimal attempts for a wide range of individuals. How to Use: Step 1: Minimize ambient light. A dark environment provides optimal results. Press the button on the bottom of the device to activate the infrared LED. Step 2: Gently press the device against the skin and slowly move it from side to side. Veins will appear as dark lines or shadows at the periphery of the red glow emitted by the device. Note: The device must remain in direct contact with the skin to function properly. Lifting it from the skin will not produce visible results. Step 3: Once a vein is located, adjust the position of the device around the area to achieve the clearest visibility. For shallow veins, slightly increase the distance if the light is too bright and obscures the vein. Follow the vein’s path to fully assess its direction and length. Note: It is best to select veins that follow a straight and consistent path. Package List: 1 x Black Vein Finder Device 3 x AAA batteries (not included)
