Infusion sets, sometimes referred to as IV administration sets, are disposable medical devices used to deliver fluids and medications from an IV source to a patient via a venous catheter. They consist of a sterile tubing assembly that connects to an IV bag or bottle, a spike to pierce the container, a drip chamber to regulate flow, a connector to the catheter, and a roller clamp or other flow control. Many sets include an injection port or luer connector and may feature a Y-site for simultaneous administration or a needleless access point.

Common variants include standard macrodrip sets (10–20 drops per milliliter) for routine IV infusions, and microdrip sets (60 drops per milliliter) used for precise dosing, especially in pediatric care. Sets can be vented or non-vented, and may include injection ports, filters, or Luer-lock connections. They are designed to be compatible with a range of IV bags, bottles, and catheters.

Infusion sets are intended for single use under aseptic conditions and are disposed of after use as medical waste. They require priming to fill the tubing and eliminate air, careful flow control, and proper connection to the patient’s catheter. Risks include air embolism, infiltration, infection, and occlusion if the line is kinked or contaminated.

Infusion sets are regulated as medical devices and governed by national and international standards. They are manufactured under sterile conditions and labeled for single-patient use. Effective disposal and infection prevention are important in clinical settings and home care. Historically, they evolved from early glass systems to plastic tubing, improving safety, sterility, and ease of use.
