  • Patent number: 11925736
    Abstract: Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.

  • Patent number: 10926014
    Abstract: The present invention relates to a cassette module for controlling fluid flows, in particular for use in blood treatment systems or in infusion systems, wherein the cassette module comprises at least one base body having means for the flow guidance of at least one fluid flow and at least two membranes which are at least sectionally directly or indirectly in contact with the base body, wherein at least one actuation element is arranged between the membranes by means of which the means for the flow guidance can be acted on.

  • Patent number: 10926015
    Abstract: The present invention relates to a cassette module for controlling fluid flows, in particular for use in blood treatment systems or in infusion systems, wherein the cassette module has at least one first functional layer and at least one second functional layer, wherein the first functional layer has means for the flow guidance of at least one fluid flow, and wherein the cassette module furthermore has at least two membranes of which the first is in contact with the means for the flow guidance of a fluid flow, and wherein the second functional layer is arranged between the two membranes and has means for generating an underpressure between the membranes.
