Heat-exchanging intravenous administration set

A heat-exchanging intravenous administration set is a sterile, single-use device that warms and delivers fluids directly from an IV bag or bottle to a patient’s vein. Clinically, it prevents hypothermia by maintaining fluid temperature during infusion, which is critical for patients at risk of cold-related complications, such as postoperative or critically ill individuals.

These devices are typically single-use and regulated as medical devices, often requiring compliance with safety and performance standards. They may include tubing, connectors, and warming chambers, though the IV bag itself may or may not be part of the set. Classification and supply vary by jurisdiction, but they are designed for non-invasive use only.
