B. Braun Caresite IV Access & Extension Sets

The Caresite line from B. Braun centers on one thing clinicians and infusion providers ask for most: a needle-free connector that swabs clean and delivers a straight, reliable fluid path. Whether you're stocking a hospital IV cart, an infusion suite, or a home-care supply closet, this collection covers the access devices, extension sets, and primary administration sets built around the CareSite needleless port.

The heart of the system is the Caresite Access Device (415122), a positive-displacement, needle-free connector rated for aspirating, injecting, or gravity flow. Positive displacement matters at disconnection—it helps push fluid outward rather than pulling blood back into the catheter, which supports catheter patency and reduces clotting risk between uses.

For connecting the patient to the line, the extension sets come in the bore size and length your protocol calls for. The small-bore 8-inch set (470100) with a 0.5 mL priming volume keeps dead space low—useful for pediatric or fluid-sensitive patients—while the standard-bore 6-inch set (470108) moves higher volumes when flow rate is the priority. The 12-inch small-bore set with spin-lock connector (470105) is DEHP-free and latex-free, an important consideration for long-dwell infusions and sensitive patients.

When you need a complete gravity setup, the Caresite Primary IV Administration Sets (354202 and 354207) pair a 15 drops/mL drip chamber with roller and slide clamps and two integrated needle-free ports, in 84-inch and 104-inch tubing lengths so you can reach the pump or pole without adding extension.

A few things buyers routinely confirm before ordering: all sets are supplied sterile, priming volumes are listed per set so you can calculate flush and medication waste, and the needle-free ports accept standard luer syringes—no blunt cannula or needle required. Match your extension bore to the flow you need, and your set length to the setup, and the Caresite pieces connect into a single consistent access system.
