SRK Plastic SRinj IV Cannula, For Clinical Use, Hospital Use, Size : Standard Size

intravenous (iv) cannulation is a technique in which a cannula is placed inside a vein to provide venous access. Venous access allows sampling of blood, as well as administration of fluids, medications, parenteral nutrition, chemotherapy, and blood products.

veins have a three-layered wall composed of an internal endothelium surrounded by a thin layer of muscle fibers that is surrounded by a layer of connective tissue. Venous valves encourage unidirectional flow of blood and prevent pooling of blood in the dependent portions of the extremities; they also can impede the passage of a catheter through and into a vein. Venous valves are more numerous just distal to the points where tributaries join larger veins and in the lower extremities.

medication, fluid and blood are some of those terms that can be received easily into the blood stream using the iv cannula. The iv cannula generally are believed to be of three types and they are peripheral iv cannula, the central line iv cannula and the last but not the least the midline iv cannula
