Abstract: A method for monitoring the reliability of an input in a medical device in which at least one value is entered into the medical device, an occurrence probability density of the at least one value is calculated on the basis of an input history, an error probability of the input is calculated from an a priori error probability density stored in a first database and loaded from the first database and the calculated occurrence probability density, and the error probability is output for further handling of the input.

Abstract: A dialyzer, a dialysis machine, a kit and a process for producing the dialyzer. The dialyzer includes a plurality of hollow fibers disposed in a housing of the dialyzer. The hollow fibers are wrapped with a textile fabric that is fluid-permeable and/or at least partly water-soluble.

Abstract: A housing-free first dialyzer element has a hollow-fiber bundle, a fluid-permeable sheath wrapped around the periphery of the hollow-fiber bundle, cast elements at the axial ends of the hollow-fiber bundle, and end caps fastened to the cast elements for connection to an extracorporeal blood circulation. A second dialyzer element has a housing and can be closed, opened and reused. A dialyzer includes the housing-free first dialyzer element and the second dialyzer element that has a housing. A blood treatment device includes the second dialyzer element that has the housing, the second dialyzer element being rigidly fastened to a machine front. A method for reprocessing the second dialyzer element that has the housing can be used after blood treatment therapy.

Abstract: A medical pressure indicator for infusion has a tube section that is combinable with a liquid-carrying filter element via an infusion line. The pressure indicator can expand and contract in at least one dimension depending on the pressure in the tube section. A sterile packaged medical pressure indicator is connectable to the outlet of a medical infusion filter. The pressure indicator is at least partly made of elastic material that can expand and contract, and can be connected to the outlet of a medical infusion filter. An infusion line can include the sterile packaged pressure indicator or an infusion filter with the medical pressure indicator.

Abstract: A dialyzer, a dialysis machine, a kit and a process for producing the dialyzer. The dialyzer includes a plurality of hollow fibers disposed in a housing of the dialyzer. The hollow fibers are wrapped with a textile fabric that is fluid-permeable and/or at least partly water-soluble.

Abstract: A method and device for controlling anticoagulation during blood treatment. The method includes conveying blood in a first line section, supplying biologically and/or pharmacologically active substances of negative total charge to the blood, separating the blood into corpuscular blood components and blood plasma, conveying the blood plasma in a second line section via an anion exchanger, bringing the blood plasma and corpuscular blood components together in a third line section, determining a first flow rate of blood plasma in the first line section, determining a second flow rate of blood plasma in the second line section, setting a quantity of biologically and/or pharmacologically active substances based on a ratio of the first and second flow rates such that, after the blood plasma and corpuscular blood components are brought together, a concentration of the biologically and/or pharmacologically active substances in the third line section meets a target value.

Abstract: A device and method for purifying blood. The method includes the steps of separating the blood plasma from the blood cells, adjusting the pH of the blood plasma to a pH close to an isoelectric point of at least one predetermined protein, treating the blood plasma by ion-exchange chromatography, neutralizing the pH of the blood plasma, and pooling of the blood plasma and blood cells.

Abstract: A device for removing noxae from blood, in an extracorporeal perfusion system, includes a housing and a plurality of hollow fibers provided inside the housing, which can be perfused by the blood. The hollow fibers each have a plurality of pores that permit the plasma of the blood to flow through the pores from an inside of the hollow fibers to an outside of the hollow fibers. The hollow fibers are modified or pretreated, in particular chemically, in such a way that they have a functionalized surface which binds the noxae to itself and removes the noxae from the blood. An inside surface of the hollow fibers includes a coating, in particular a hemocompatible and anticoagulant coating, which is arranged to prevent damage to the cellular components of the blood when the blood flows through the hollow fibers. An extracorporeal perfusion system includes the device.

Abstract: A dialyzer and a method of manufacture thereof, wherein the dialyzer includes a tubular dialyzer housing in the interior of which a plurality of capillaries each extending in the longitudinal direction of the dialyzer housing and being juxtaposed transversely to the longitudinal direction is arranged, with a filler having a volume-increasing property being arranged between the inner wall of the dialyzer housing and the capillaries.
