Product Details

An IV cannula, also known as an intravenous cannula or IV catheter, is a medical device used to administer fluids, medications, or draw blood directly into a patient's vein. It consists of a thin, hollow, and flexible tube made of materials such as plastic or metal. The IV cannula is typically inserted into a vein through a process called venipuncture. It is commonly used in healthcare settings, including hospitals, clinics, and ambulances, to deliver intravenous therapy and facilitate blood sampling for diagnostic purposes. The cannula is available in various sizes, indicated by different gauges. The gauge refers to the diameter of the needle or the outer diameter of the cannula. Smaller gauge numbers represent larger diameters, allowing for faster flow rates and the administration of thicker fluids. IV cannulas are designed with a sharp beveled needle or a small, retractable needle for easy insertion into the vein. Once the needle is properly placed, a flexible catheter remains in the vein, allowing for fluid or medication administration without the need for repeated needle insertions. To secure the IV cannula in place and prevent it from dislodging, it is typically attached to the patient's skin using adhesive dressings or securement devices. The site of insertion should be regularly monitored for signs of complications, such as infection or infiltration. In summary, an IV cannula is a medical device used to access a patient's vein for the administration of fluids, medications, or blood sampling. It plays a crucial role in delivering intravenous therapy and facilitating various medical procedures.
