FIELD: medicine.
SUBSTANCE: invention relates to medical simulators and can be used to optimize angiographic scanning protocols, scientific research of hemodynamics of large vessels, as well as training of surgical skills. Disclosed is a method in which conversion of a control analogue signal into sinusoidal oscillations and their transmission to windings of an electric motor of a pump by means of pulse-width modulation is used.
EFFECT: invention provides generation of controlled pulsating flow with specified characteristics in test object directly without the need to use additional devices affecting the output line.
