PVC Catheters

PVC is a synthetic plastic polymer. PVC catheters are translucent, allowing patients and their medical providers to see the color of the urine easily. PVC is also firm, but fairly flexible for easy insertion. It is also known as vinyl catheter. PVC catheter eliminates the latex allergy concerns.
The catheter is introduced into the vein by a needle (similar to blood drawing), which is subsequently removed while the small plastic cannula remains in place. The catheter is then fixed by taping it to the patient's skin or using an adhesive dressing.
A peripheral venous catheter is the most commonly used vascular access in medicine. It is given to most emergency department and surgical patients, and before some radiological imaging techniques using radio contrast.
A peripheral venous catheter is usually placed in a vein on the hand or arm. It should be distinguished from a central venous catheter which is inserted in a central vein (usually in the internal jugular vein of the neck or the subclavian vein of the chest), or an arterial catheter which can be placed in a peripheral or central artery.
