Patent number: 12023158Abstract: A whole blood filtration device is provided with a filter membrane separating a feeding volume and a clean side of the filter membrane from each other. The feeding volume communicates with a first feeding side opening and with a second feeding side opening. The filter membrane has pores with a pore size that ensures permeability of the filter membrane to blood plasma/serum and that retains blood cells. The first feeding side opening can be coupled to a first blood pump for feeding blood from the first feeding side opening into the feeding volume so that blood plasma/serum permeates the filter membrane and blood cells, retained by the filter membrane, exit from the feeding volume through the second feeding side opening.Type: GrantFiled: June 3, 2020Date of Patent: July 2, 2024Assignee: MANN+HUMMEL GmbHInventors: Dagmar Winkler, Heike Rupp, Steffen Schuetz, Dietmar Talmon-Gros, Michael Fasold, Alfons-Alois Schwinghammer, Frank Bartel, Sascha Bauer, Patrick Nytz

Patent number: 10675399Abstract: A whole blood hollow fiber membrane filter medium is made of a polymeric material having pores of a pore size that ensures permeability to blood plasma or serum but retains blood cells. The whole blood hollow fiber membrane filter medium is used for filtering a whole blood sample so that blood plasma or serum passes through the whole blood hollow fiber membrane filter medium and blood cells are retained. The obtained blood plasma shows no hemolysis.Type: GrantFiled: November 11, 2015Date of Patent: June 9, 2020Assignee: MANN+HUMMEL GmbHInventors: Steffen Schuetz, Heike Rupp, Dagmar Winkler, Frank Ehlen

Patent number: 10561781Abstract: A blood filtering device has a filtration section with filter medium separating raw side and clean side. A first communication path connects raw side and a first variable blood reservoir volume; a second communication path connects raw side and a second variable blood reservoir volume coupled to a receptacle. When varying the first variable blood reservoir volume, blood contained therein flows through first communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through second communication path into the second variable blood reservoir volume. When varying the second variable blood reservoir volume, blood contained therein flows through second communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through first communication path into first variable blood reservoir volume.Type: GrantFiled: December 12, 2015Date of Patent: February 18, 2020Assignee: MANN+HUMMEL GmbHInventors: Dagmar Winkler, Heike Rupp, Claudio Weiss, Karlheinz Muenkel, Joachim Stinzendoerfer, Steffen Schuetz, Sascha Bauer, Frank Bartel, Alfons-Alois Schwinghammer, Michael Fasold, Dietmar Talmon-Gros, Norbert Strassenberger, Anton Rabanter

Patent number: 10478780Abstract: A separating device for separating an undesired fluid from a multi-component liquid has a region flowed through by the multi-component liquid and at least one membrane disposed in the region to separate a first fluid region from a second fluid region. The membrane has a first permeability to the undesired fluid and a second permeability to the multi-component liquid. The first permeability is different from the second permeability. The membrane is equally permeable to all components of the multi-component liquid. The membrane is permeable to the multi-component liquid and impermeable to the undesired fluid, or the membrane is impermeable to the multi-component liquid and is permeable to the undesired fluid, wherein the multi-component liquid is a liquid multi-component operating medium. A filter with such a separating device and a filter element, in particular for diesel fuel, as well as a liquid system with such a separating device are described.Type: GrantFiled: August 24, 2017Date of Patent: November 19, 2019Assignee: MANN+HUMMEL GmbHInventors: Heike Rupp, Steffen Schuetz, Dagmar Winkler

Patent number: 10350516Abstract: A blood filtering device has a tubular housing with a tubular section and tubular housing volume. A filtration section with a filter medium separating a raw side from a clean side is arranged in the tubular housing. The filtration section is movable along the tubular section and movably sealed relative to the tubular housing. The filtration section separates the tubular housing volume into variable first and second tubular housing volumes. A first communication path extends between raw side and first tubular housing volume. A second communication path exits between raw side and second tubular housing volume. When moving the filtration section, blood in the first tubular housing volume flows through the first communication path to the raw side; blood plasma passes through the filter medium to the clean side; residual blood flows through the second communication path into the variable second tubular housing volume.Type: GrantFiled: December 28, 2015Date of Patent: July 16, 2019Assignee: MANN+HUMMEL GmbHInventors: Dagmar Winkler, Heike Rupp, Steffen Schuetz, Karlheinz Muenkel, Joachim Stinzendoerfer
