Some Introduction of ECMO Centrifugal Pump Magnet

COVID-19 is spreading across the globe and becoming more and more serious. The treatment guide for COVID-19 issued by the National Health Commission of the People’s Republic of China indicated that ECMO can be utilized for the salvage treatment of the severe case. ECMO, also known as extracorporeal membrane oxygenation, is an extracorporeal technique of providing prolonged cardiac and respiratory support to persons whose heart or lungs are unable to provide an adequate amount of gas exchange or perfusion to sustain life. The standard ECMO circuit consists of the blood pump, membrane oxygenator, gas exchanger, heat exchanger, monitoring system and different kinds of cannula. As the core components of them, blood pump and membrane oxygenator act as heart and lungs of the patient respectively. ECMO circuit is connected to patient via cannula which placed in veins and arteries of the leg, neck or chest, then pump blood from the body to oxygenator to exchange oxygen and carbon dioxide. Thus, sends blood back to the body. It is the same as ventilator magnet that ECMO centrifugal pump magnet also caught our attention.

About ECMO Centrifugal Pump Magnet

Both roller pump and the centrifugal pump are utilized in the clinic. Centrifugal pump has many merits compared with roller pump, includes less damage to blood, large pressure buffer and high safety. ECMO centrifugal pump magnet is essentially a magnetic coupling device. Magnetic chamber in the pump head will form coupled connection with magnetic device of driving motor. Then high-speed rotating motor will drive impeller which inside the pump to rotate at high speed and thus generate vortex and centrifugal force to push blood forward.
