Some individuals have veins that are small or deep, which can make it difficult for healthcare professionals to identify them quickly and accurately. Repeated attempts can cause discomfort and may affect patient confidence during the procedure. This device assists in visualizing veins, which may be beneficial in clinical settings or for personal use, and is designed to help minimize attempts when locating veins. How to use: Step 1: Reduce ambient light. Use in a dimly lit environment for optimal results. Press the button on the bottom of the device to activate the IR LED. Step 2: Gently stretch the skin with one hand and slowly move the device side to side while maintaining contact with the skin. Veins will appear as dark lines or shadows visible at the periphery of the device, illuminated in red. Note: The device must remain in contact with the skin to function properly. Lifting it away from the skin will prevent visualization. Step 3: Once veins (shadows/lines) are visible, adjust the position of the device over the area for improved clarity. For superficial veins, slightly increase the distance between the device and skin if the light appears too bright, as this may obscure the vein. Follow the path of the vein to determine its direction and size. Note: It is recommended to select a straight section of vein when possible.
