Learning the parts of a cannula helps us use it in the right way. A cannula is used in healthcare settings, such as hospitals and clinics, due to their ability to provide a continuous and stable way to access veins. When you will use a cannula, then you have to know the functions of each part of a cannula. In this article, we are going to share a list of parts of a cannula with their functions and uses in English. Learn the entire lesson, which will help you know how to use parts of cannulas.

In this section, we will cover all the parts of cannulas in English with their uses and helpful images. Learning the functions and uses of these parts is essential for safe and effective use of a cannula.

Main Parts of a Cannula and Their Uses
- Lever Lock Plug: The lever lock plug is a safety feature designed to lock the cannula into place, preventing accidental dislodgement during use.
- Needle Grid: This is part of the structure that helps secure the needle within the cannula, allowing for precise insertion into the vein or artery.
- Injection Port Cap: The injection port cap allows for medications or fluids to be injected directly into the cannula without having to remove or replace it, making the process more efficient and less invasive.
- Flashback Chamber: The flashback chamber allows healthcare professionals to see a flash of blood, indicating that the needle is correctly placed inside the vein, ensuring proper insertion.
- Valve: The valve regulates the flow of fluids and prevents backflow, maintaining consistent administration of intravenous fluids or medications.
- Catheter Hub and Wings: The catheter hub and wings provide a handle for securing the cannula in place, often taped down on the skin, to prevent movement during treatment.
- Blushing: Blushing is the area where blood flow is observed once the needle is properly positioned in the vein. It confirms successful placement.
- Catheter: The catheter is a small, flexible tube inserted into the vein. Once the needle is removed, the catheter remains in the vein to allow the passage of fluids or medications.
- Needle: The needle is used to puncture the skin and access the vein. After insertion, the needle is retracted, leaving only the catheter inside the body.
