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.

Abstract: An interrupter unit includes a vacuum switch tube and an insulating housing. The insulating housing has an inner surface. The vacuum switch tube is bordered at least partially by an electrically insulating structure material having an outer surface. The insulating housing at least partially surrounds the vacuum switch tube. In operation, inner surface of the insulating housing and outer surface of the vacuum switch tube are separated by an adhesion layer. The inner surface and the outer surface are provided at least partially with an electrically conductive layer such that, in a boundary region between vacuum switch tube and insulating housing, the following layer sequence is directed radially outwards from a switch axis: structure material of vacuum switch tube; outer surface of structure material; conductive layer on outer surface of structure material; adhesion layer; conductive layer on insulating housing; inner surface of insulating housing; volume material of insulating housing.

Abstract: A shaft seal assembly for a rotating shaft assembly includes a shaft seal and a bore insert that encircles a shaft. The bore insert can fill a bore space disposed between an oil sealing assembly and a housing of the rotating shaft assembly. The shaft seal includes a shaft seal arm that can contact the bore insert and provide a seal.

Abstract: A sealing assembly having a first metal seal ring including a first lateral face defining a first seal surface and a second metal seal ring including a second lateral face defining a second seal surface that is configured to form a face-to-face seal with the first seal surface. The first lateral face includes a laterally-facing groove positioned radially outward of the first seal surface. An annular debris barrier is configured to be received within the groove.
