Providing quality patient care efficiently and minimizing the risk of complications The BD Nexiva™ Diffusics™ Closed IV Catheter System is designed to address common CT I.V. challenges during power injection procedures. Reduces the destabilizing effects that can lead to extravasation. Catheter tip features multiple teardrop-shaped diffusion holes to reduce forces that cause catheter motion in the vein by up to 67%. Enables high flow rates with patients that may require a smaller IV catheter. Enables higher flow rates with a smaller gauge catheter (22G - 24G), facilitating difficult venous access situations. All-in-one catheter and extension set built for your power injector's 325 psi setting. BD Instaflash™ Needle Technology confirms immediate vessel entry, designed to help improve first-stick success. BD Vialon™ Biomaterial enables longer dwell times, supporting the current Nursing Standards of Practice for clinically indicated site rotation.
