PULSAR DEVICE FOR PERFORMING AUXILIARY BLOOD CIRCULATION Russian patent published in 2005 - IPC

Abstract RU 2244568 C2

FIELD: medical engineering.

SUBSTANCE: device has wireless generator of blood flow oscillations based on two-step centrifugal injector having controllable elastic reservoir volume. Pulsating mode is provided due to pulsar passage cross-sections being selected in a way that pressure and flow rate pulsations arise at the outlet when two flows interact, their amplitude and frequency are adjustable using auxiliary elastic reservoir.

EFFECT: enhanced effectiveness in creating pressure and flow rate pulsations without applying external pressure-vacuum source.
