METHOD OF ARTIFICIAL TRANSMISSION OF PHYSIOLOGICAL LIQUID Russian patent published in 2018 - IPC A61M1/10 

FIELD: medicine.

SUBSTANCE: invention relates to cardiology and can be used for pumping blood. Method is carried out by means of a pump in which the undulating motion of the fluid in a closed volume is used, It is created by compression and stretching of piezoelements by applying a variable three-phase exciting voltage. Pump consists of three series-connected piezoelectric injection modules, containing internal and external channels for fluid and pumped blood. External channels of the piezoelectric injection modules are interconnected, and the internal channels are connected in series. Pump is transdermally introduced into the arterial vessel and advanced into the thoracic aorta. Circulation is maintained by applying power to the piezoelements.

EFFECT: technical result consists in increasing the productivity of the pump, reducing the overall dimensions and weight.
