摘要： A blood pump includes a hollow body in which an impeller with blading is provided for producing an axial propulsion of blood along the impeller. An at least partly actively stabilized magnetic bearing device is provided wherein the impeller may be set into a rotation about a rotation axis of the impeller, with a motor stator. The hollow body has an inlet for the flow of blood into the hollow body in an inflow direction which is essentially parallel to the rotation axis, and an outlet for the outflow of the blood out of the hollow body in an outflow direction.

摘要： A blood pump has a hollow body in which an impeller with a spiral blading produces an axial propulsion of blood along the impeller, as well as an at least partly actively stabilized magnetic bearing device and a hydrodynamic bearing device for the impeller. The impeller may be set into a rotation about a rotation axis of the impeller with a motor stator located outside the hollow body. The hollow body has an inlet for the flow of blood into the hollow body in an inflow direction which is essentially parallel to the rotation axis, and an outlet for the outflow of the blood out of the hollow body in an outflow direction which is offset to the rotation axis of the impeller to produce a non-zero outflow angle (α) between the inflow direction and the outflow direction. A total artificial heart can be formed from two such blood pumps.

摘要： Method for controlling an assist pump for fluid delivery systems with pulsatile pressure. If for example a heart assist pump is driven with a constant number of revolutions, it is achieved, that the blood is also delivered through the assist pump, even when the heart chamber is in the decontraction phase. With the present method it is achieved, that an assist pump only acts supportingly in the pressure phase of the main pump, in such a way, that the pressure difference between the input side and the output side of the assist pump is continuously determined and the number of revolutions of the assist pump is controlled in such a way, that the determined pressure difference does not fall below a predetermined value and the rate of flow does not sink below zero.

摘要： A delivery device for a single- or multiphase fluid having a tubular body for axially guiding the fluid, including a motor stator arranged outside the tubular body and a delivery element arranged within the tubular body, comprising a motor rotor. A rotor gap is formed between the delivery element and the hollow body for allowing the fluid to pass through. Mounting arrangements are fixedly disposed in axial direction on each side of the delivery element within the tubular body. Hub gaps are formed between the delivery element and the mounting arrangement. First permanent magnet bearing elements are disposed in the mounting arrangement and second permanent magnet bearing elements are disposed in the delivery element. The first and the second permanent magnet bearing elements functionally work together and are magnetized in axial direction and have opposite polarity. Position sensors associated with each of the first permanent magnet bearing elements and a stabilizer is disposed around the hollow body.
