Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used for bottles, other non-food packaging, and cards (such as bank or membership cards).
In medicine, a peripheral venous catheter (PVC or peripheral venous line or peripheral venous access catheter) is a catheter (small, flexible tube) placed into a peripheral vein in order to administer medication or fluids.Upon insertion, the line can be used to draw blood.The catheter is introduced into the vein by a needle (similar to blood drawing), which is subsequently removed while the small tube of the cannula remains in place. The catheter is then fixed by taping it to the patient's skin (unless there is allergy to adhesives).he catheter is introduced into the vein by a needle (similar to blood drawing), which is subsequently removed while the small tube of the cannula remains in place.
