Infusionssets

Infusion sets are sterile disposable devices used to deliver intravenous fluids, medications, or nutrition from a source bag or bottle to a patient via a peripheral venous catheter, central line, or implanted port. A typical infusion set includes tubing, a drip chamber, a roller clamp or flow regulator, a protective cover, and an end connector that attaches to the catheter or to a secondary administration set. Some configurations have a needleless access component, a Y-site for a secondary infusion, or a vented or non-vented drip chamber to control flow.

Types and configurations: Sets vary by drip mechanism (macrodrip or microdrip), connection standards (luer-lock or slip), and whether they are used as a primary line or for a secondary (piggyback) infusion. They may be gravity-fed or compatible with infusion pumps. Extension sets and syringe infusion sets are common variants.

Usage and safety: Infusion sets are intended for single-patient use to minimize infection risk. They must be primed to remove air, connected using aseptic technique, and monitored for flow rate and patency. Potential risks include infection, air embolism, occlusion, and infiltration. Materials may vary; some sets are designed to be DEHP-free or latex-free. After use, the device is disposed as medical waste; sharps are placed in a suitable container.

Regulation: Infusion sets are regulated as medical devices in many regions and must meet standards for sterility, labeling, and traceability. Proper documentation, supplier recalls, and compatibility with drugs and equipment are maintained by healthcare providers.
