I.V Cannula

IV cannula is a critical medical device used to access a patient’s vein for intravenous therapy. It allows direct delivery of fluids, medications, and blood products into the bloodstream. As a result, it plays a key role in emergency treatment, inpatient care, and routine clinical procedures.

The device consists of a sharp stainless-steel needle housed within a soft, flexible plastic catheter. First, the clinician uses the needle to puncture the vein. Then, the catheter slides into position while the needle is withdrawn. This approach minimizes trauma to the vein and increases patient comfort during extended use.

IV cannula comes in a wide range of sizes, each marked with color codes for quick identification. For example, smaller gauges are ideal for pediatric or geriatric patients with delicate veins. In contrast, larger gauges support high-volume infusions or rapid blood transfusions. Therefore, choosing the correct size ensures both safety and efficiency.

In addition, many cannulas include an integrated injection port and a one-way valve. These features allow medical staff to administer additional medications without interrupting the primary infusion. Some versions also feature stabilizing wings for easier handling and secure taping.

To confirm proper placement, the cannula includes a flashback chamber. This chamber displays a small amount of blood when the needle enters the vein, providing instant visual feedback. Consequently, clinicians can reduce the number of insertion attempts and save valuable time.

Furthermore, the cannula comes in sterile, single-use packaging to ensure infection control. Once inserted, healthcare providers secure it with sterile adhesive dressings, preventing movement and lowering the risk of complications.

IV cannula offers a fast, safe, and reliable solution for vascular access. Its combination of comfort, functionality, and safety features makes it an essential tool in both acute and long-term care. Whether used in hospitals, emergency services, or outpatient settings, it supports precise and efficient delivery of intravenous therapy.
