The catheter hub is a critical component of intravenous (IV) therapy, providing a direct route for blood to enter and exit the body via the veins. It is an integral part of the IV line, connecting the intravenous bag with the patient's bloodstream, and plays a vital role in maintaining the cleanliness and hygiene of the system.
Catheters are used for a wide range of medical procedures, including chemotherapy infusions, total parenteral nutrition (TPN), and drugs that need to be delivered rapidly or over a long period. They are also used as diagnostic tools, such as chest tubes or central lines that monitor central blood pressure or drain accumulated fluid from the pleural or peritoneal cavities.
The design of the catheter hub is crucial to ensure its effectiveness and patient safety. It must be made from biocompatible materials that can withstand the forces applied during manipulation, and it should facilitate easy and clean attachment to the IV line. Hubs come in various sizes and shapes, depending on the specific requirements of the procedure, and the hub's design may vary depending on the manufacturer's specifications.
