Publication number: 20200359952Abstract: 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: ApplicationFiled: June 3, 2020Publication date: November 19, 2020Inventors: Dagmar Winkler, Heike Rupp, Steffen Schuetz, Dietmar Talmon-Gros, Michael Fasold, Alfons-Alois Schwinghammer, Frank Bartel, Sascha Bauer, Patrick Nytz

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: 10143950Abstract: A filter (10) for liquid has a filter housing (14) with at least one hollow filter element (12). The filter element at least partially surrounded by a liquid guidance region (54). At least one additive chamber (50) of an additive dispensing device (38) is disposed on the side of the liquid guidance region (54) opposite the corresponding exterior side of the hollow filter element (12) by means of at least one partition (42). The at least one partition has at least one dispensing port (52) by means of which the at least one additive chamber (50) can be fluidically connected to the liquid guidance region (54). The at least one dispensing port (52) is closed with at least one closure element (58) at least in the original condition of the additive dispensing device (38), this closure element being dissolvable by the liquid to be treated to release the at least one first dispensing port (52) during operation of the filter (10).Type: GrantFiled: December 14, 2014Date of Patent: December 4, 2018Assignee: MANN+HUMMEL GmbHInventors: Alfons Alois Schwinghammer, Pamela Gohl, Carolin Marquardt, Stephan Niemeyer
