IV Cannulas & Tubing are sterile, single-use medical devices that together constitute the complete peripheral intravenous access and delivery system. The IV cannula (peripheral intravenous catheter) is a flexible catheter mounted over a hollow introducer needle, inserted into a peripheral vein to establish vascular access for fluid, medication, and blood product administration. Available in gauges 14G-26G, with material options including FEP/Teflon® and polyurethane, and featuring passive or active sharps safety mechanisms. IV tubing (administration sets) is a flexible conduit connecting the fluid container to the cannula, incorporating drip chambers, flow regulators, injection ports, and needleless connectors. Available in macro-drip, micro-drip, filtered, light-protective, and non-PVC variants. Strict aseptic insertion technique, immediate sharps disposal, routine site assessment, and adherence to single-use protocols are essential to prevent phlebitis, bloodstream infection, and needlestick injury.
