Terumo Sarns 9000

Terumo Sarns 9000 Perfusion System

The Terumo Sarns 9000 Perfusion System is a state-of-the-art extracorporeal circulation device designed for arterial perfusion, regional perfusion, and cardiopulmonary bypass procedures. This advanced system features an occluder for rapid or gradual adjustment of venous line blood flow, ensuring optimal perfusion management during critical cardiac surgeries. With a continuously charged backup battery pack that automatically takes over in case of AC power failure, the Sarns 9000 delivers reliable performance even under emergency conditions. An optional water mixing system enables precise temperature control for cardioplegia and arterial heat exchangers by blending hot and cold water from a wall supply, allowing rapid adjustments to patient temperature.
