Abstract: An artificial heart system for human beings or other creatures, comprises at least one half of the heart, to be implemented into the body, instead of or in parallel to the biologic heart or outside of human body for example for a portable dialysis apparatus, maintaining or supporting at least one blood circulatory system or circuit of the human being or the other creature as a pump, completely or partially, and at least one drive unit and at least one control unit, preferably to be placed outside the body.

Abstract: The invention relates to a blade-type check valve for gaseous and liquid media, to be used in medical technologies as well as in waste water technology with at least three triangular blades, grouped in round configuration at the edges of a polygonal bore of a valve ring or housing, with the number of blades corresponding to the number of faces of the bore. At least at one of the three sides, the valve blades feature an integrated joint, which may also consist of fabric, whereas the two other sides of the valve blades form an articulated lock. The valve can be installed in any position and closes automatically, actuated by the backflow respectively return flow of the medium, without external energy.

Abstract: A slim and long multifunctional gripping mechanism has a bending- and torsion-resistant structure, on which several finger, suction, magnetic head and other mechanisms for a multitude of tasks are arranged. The gripper arm is composed in sandwich configuration of several cages placed on top of each other, like a multi-stage tower. The individual cages consist of two plates in parallel in lightweight construction, with their mutual distance being ensured by several rods, spokes, wires, ropes and strings. Most of the drives are contained within the first cage after the flange. From that position, all mechanisms participating in the action of the gripper are driven by rods, shafts, ropes, chains or belts traversing the cages. Further cages are used to attach and accommodate the components of finger mechanisms. Movable cages are used as drives for finger, suction or magnetic head mechanisms. Several finger mechanisms perform a different task each.

Abstract: The invention relates to an artificial heart of human beings and other creatures with at least one half of a heart, to be implemented instead of or parallel to the natural heart, maintaining as a pump completely or partially as a support one circulatory system or two circulatory systems of the human being or other creature. Within a hard and hermitically locked shell, two chambers are provided, one blood and one drive chamber. The drive chamber is cyclically filled and discharged by a pump actuated by electric motor. Due to the pressure and the suction of the drive chamber, the blood from the blood chamber is transported to the arteries and from the veins into the blood chamber. In the course of this process, blood and drive chamber only move to the half, in a completely unstressed manner without elastic stretching or kinking. Two innovative artificial check valves ensure that the blood flows exclusively in the desired direction.
