Relevant IV Cannula Set Parts

An intravenous (IV) cannula set is a crucial medical device used to administer fluids, medications, and blood products directly into a patient’s bloodstream. It consists of several important parts that work together to ensure safe and efficient delivery of intravenous therapy. In this blog post, we will explore the different components of an IV cannula set and their functions.

1. Cannula

The cannula is the primary component of an IV set. It is a thin, hollow, plastic tube that is inserted into a patient’s vein. The cannula allows for the passage of fluids and medications into the bloodstream. It comes in various sizes, and the selection depends on the patient’s age, condition, and the type of therapy being administered.

2. Needle

The needle is a sharp, stainless steel component that is attached to the cannula. It is used to puncture the skin and penetrate the vein during the insertion process. Once the cannula is in place, the needle is withdrawn, leaving the plastic tube inside the vein.

3. Winged Infusion Set

A winged infusion set, also known as a butterfly needle, is a type of IV cannula set mainly used for delicate veins or when the patient requires frequent blood sampling. It consists of a small butterfly-shaped plastic hub with short tubing attached to it. The wings provide stability during insertion, while the tubing allows for fluid delivery.

4. Injection Port

An injection port, also called a flush or access port, is a small rubber or silicone piece integrated into the IV cannula set. It allows healthcare providers to inject additional medications or fluids without disturbing the primary IV line. The injection port is usually located close to the patient’s arm, making it easily accessible.

5. Extension Set

An extension set is an additional tubing that connects the cannula to the IV bag or other infusion devices. It extends the length of the IV line, providing flexibility and enabling easy movement for the patient. Extension sets come in various lengths and configurations to meet different clinical needs.
