Novosibirsk scientists have created an artificial heart based on a disk pump
«The pump we have developed is fundamentally different from those currently used in transplantology. We use a different rotor; not blades, but a package of discs that pump blood during rotation thanks to the friction of fluid. We hope that our pump will help conserve blood during pump’s work in a human body, since red blood cells themselves do not come in contact with the discs,» said Alexander Chernyavsky.
The pump allows to pump about 5 or 6 litres of liquid for 2000−2500 revolutions, explained Chernyavsky. The scientists estimate that the pump they have developed will theoretically increase the working time of an artificial heart, which for now does not exceed 9 hours.
