Specifications
The V800P device is a vein finder designed for blood vessel assessment and venipuncture optimization. It uses Near-Infrared (NIR) light at a wavelength of 850nm. The device supports both fine and basic modes, with a pediatric size option available. It features a unique smart depth detection system that suggests needle entry angles based on vein depth, indicated by green blocks.

Clinical Applications and Benefits
The device is indicated for venipuncture, cosmetic, and vascular procedures. It is particularly beneficial for patients with difficult venous access, increasing the success rate of peripheral cannulation and reducing the need for central vascular access devices. The use of this technology improves patient satisfaction, saves time, and is cost-effective.

Clinical Recommendations
The Projection Vein Finder significantly reduces the first venipuncture failure rate by 77.5% and the infiltration rate by 61.4%, as demonstrated in a comparative study of 360 cases published in the Journal of Nursing Administration in September 2015.

Safety and User Interface
The device includes a convenient user interface with buttons for adjusting brightness, switching modes, and setting the device to standby. It also features indicators for machine status, battery status, and power source.
