Temporary Dual-Lumen Hemodialysis Catheter
The image displays a recently inserted temporary dual-lumen hemodialysis catheter positioned in the left internal jugular vein of a patient. This type of central venous access device serves as a crucial but temporary vascular access option for patients requiring urgent or short-term hemodialysis treatment. The catheter features two color-coded lumens—red for arterial (blood withdrawal) and blue for venous (blood return)—that facilitate the extracorporeal blood circuit necessary for dialysis.
Peripherally Inserted Central Catheters (PICCs) Diagram
A Peripherally Inserted Central Catheter, commonly known as a PICC line, is an essential medical device that provides prolonged intravenous access for patients requiring long-term medication administration, nutritional support, or frequent blood sampling. This thin, flexible tube is inserted through a peripheral vein, typically in the upper arm, and advanced until the tip reaches a central vein near the heart. PICC lines have revolutionized patient care by reducing the need for repeated needle sticks and providing a reliable vascular access route for extended periods, ranging from weeks to months.
