Multi-Port Extension Sets – Manifold Solutions for Multiple Infusions Through One Access

Multi-port IV extension sets provide multiple access points or branches from a single catheter or primary line, allowing several medications or fluids to infuse concurrently through one vascular access site. These sets commonly use bifuse, trifuse, or manifold designs with integrated stopcocks, one-way valves, and needle-free ports to support complex therapy regimens while maintaining a closed system.

By consolidating multiple infusions into a single, organized extension assembly, multi-port sets help reduce the number of catheters required, simplify line management, and improve pump organization at the bedside. They are particularly valuable in critical care, oncology, and procedural environments where patients receive many simultaneous medications.

What You Can Order in This Category

• Bifuse Extension Sets — Two-branch designs that support two infusions or an infusion plus intermittent access through a single line.
• Trifuse Extension Sets — Three-branch configurations for more complex infusion regimens, often equipped with needle-free valves.
• Manifold Extension Sets — Multi-port manifolds with several one-way valves or stopcocks designed to organize multiple lines from one connection point.
• Multi-Port Sets with Needle-Free Valves — Swabable ports on each branch that support safe, closed-system syringe access.
• Filtered Multi-Port Extensions — Configurations that include inline filtration on selected branches for sensitive medications or blood products, depending on model.

Technical Specifications Available

• Port configurations: Bifuse (two branches), trifuse (three branches), and manifold assemblies with three or more ports.
• Valve options: One-way valves to help reduce backflow, stopcocks for branch control, and needle-free connectors at branch ends.
• Bore and priming volumes: Microbore options for critical medications or standard-bore tubing for higher-flow infusions, with defined priming volumes for each branch.
• Lengths: Short manifolds positioned near the catheter hub or longer extensions that move the multi-port assembly away from the insertion site.
• Materials: Non-DEHP, latex-free tubing designed for compatibility with commonly used IV fluids and medications.

Where Multi-Port Extension Sets Are Used

Multi-port extension sets are most commonly used in intensive care units, cardiac units, oncology and hematology wards, and operating rooms where patients routinely receive multiple simultaneous IV medications. They are also valuable in emergency and step-down units when vascular access is limited but therapeutic complexity is high. By centralizing multiple infusions into a single assembly, these sets support safer line organization, clearer pump labeling, and fewer catheter insertions.
