  • Publication number: 20130110229
    Abstract: The technical result of the invention comprises maintaining the physiological structure of the flow of blood, both in the open and in the closed state of a valve on account of the construction and shape of the cusps. The technical result is achieved in that the heart valve prosthesis comprises a body with a flange, and a closing unit in the form of three cusps mounted in the through opening in the body, wherein each of the cusps has a central rib directed from the centre of the through section of the valve to the body, and convex-concave wings are arranged along the sides of the rib, and cusps are mounted in the body by means of a mounting unit, wherein, in the closed position, the geometry of the valve reproduces the geometry of an actual aortal valve.

  • Publication number: 20110152599
    Abstract: The invention 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 patient's 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 + Z 0 ? ( t ) ] 2 ( 1.1 ) ? = ? 0 + k ? ( t ) ? z ( 1.

  • Publication number: 20090090423
    Abstract: The invention relates to hydroaeromechanics, heat and mass exchange and power engineering, medical instrument engineering, and other branches of economy, in which the motion of a continuous medium (gases, liquids, and mixtures thereof) defines the functional and technical-and-economical efficiency. It relates to the method of forming the currents of a new type whose flow has the embedded tornado-like jets connected with the boundary layer on the streamlined surfaces, sucking this layer out and transferring the sucked mass into the main stream.

  • Patent number: 7331752
    Abstract: A device and method for conversion of the energy of medium flows are provided. The proposed device and method ensure suppression of the vortex streams in the flow on the leg of its motion along the radially converging trajectories and concentration of the flow energy, which is expressed by the increase of its velocity and decrease of the summary area of the cross section of the converging trajectories. As the flow runs along the first system of helical trajectories the following takes place: the harmful secondary vortex jets continue attenuating, the degree of concentration of the flow energy increases and velocity components form in the flow, which correspond to natural vortex streams, for instance, tornadoes, whirlpools.

  • Publication number: 20040240984
    Abstract: A flow being converted is directed through a convergent tube chamber formed by a shell of revolution via two screw channels systems whereas in the first screw channels system the flow is twisted and transfers its energy to a turbine installed on an axis located on a support structure in the second screw channels system the flow is directed through screw channels where a flow with reduced pressure is formed providing transportation of the first flow coming out of the turbine. The channel system may be equipped with a surface generating vortices, guide blades realised in a form of movable elements. The unit is equipped with a electrical generator, which can be installed in any zone, a system of floating suspensions, a rotational speed stabiliser, and a heat accumulator.
