摘要：: The device relates to clinical cardiology and cardiovascular surgery. The method for forming a blood flow in research stands and in surgically reconstructed segments of the blood circulation system comprises diagnosing the individual condition of a patients blood circulation system measuring the blood flow velocity field in the heart chambers and great vessels comparing the parameters measured against the physiological norm determining parameters forming a swirled blood flow and modeling an individual swirled blood current in the blood circulation system being diagnosed, the streamlined surfaces and guide elements of flow channels of the blood circulation system reconstructed being given shapes conforming to the flow lines of the restored normally swirled blood flow in accordance with formulas:Q⁡(t)=z+Z0⁡(t)⁢r2φ=φ0+k⁡(t)⁢zk⁡(t)=Γ0⁡(t)4⁢π⁢⁢Q⁡(t)⁢C0⁡(t)⁢⁢Vz=2⁢C0⁡(t)⁢z⁢⁢Vr=-C0⁡(t)⁢r⁢⁢Vφ=Γ0⁡(t)2⁢π⁢⁢r⁢{1-exp[-C0⁡(t)⁢r22⁢v]}.
