  • Patent number: 11771813
    Abstract: A hydrophobic filter for filtering an airflow or another gaseous flow in a medical application has a housing encompassing a filter chamber, an inlet port arranged on the housing and forming an inlet opening, an outlet port arranged on the housing and forming an outlet opening, and a hydrophobic structure extending along a plane of extension and separating the filter chamber into an inlet chamber and an outlet chamber. The inlet opening opens into the inlet chamber and the outlet opening opens into the outlet chamber. Herein, the outlet opening opens into the outlet chamber at a first location when viewed along the plane of extension and the inlet opening opens into the inlet chamber at a second location different from the first location when viewed along the plane of extension.

  • Patent number: 10322216
    Abstract: The present invention relates to a filtering device (8) for removing substances from blood or a blood component, the filtering device (8) comprising: a housing having an inlet and an outlet, at first sorbent material coupled with at least a first ligand located within the housing, and a second sorbent material coupled with at least a second ligand located within the housing, wherein the first ligand is for removing free hemoglobin (fHb) and the second ligand is for removing microvesicles (MV) from the blood or blood component passing through the filtering device (8), from the inlet to the outlet, wherein the first and second ligand are different from each other, and wherein the first and second sorbent material are the same or are different from each other.

  • Patent number: 10004840
    Abstract: The invention relates to a blood filter, a system comprising a blood filter and the use of a blood filter or system for the removal of substances from whole blood or blood components. According to the invention, a blood filter comprises an inlet (2), an outlet (3) and at least first fibers disposed between the inlet (2) and the outlet (3) for filtering a fluid being communicated between the inlet (2) and the outlet (3), wherein each of the first fibers comprises at least one groove extending in the longitudinal direction of the fiber.

  • Patent number: 8691098
    Abstract: A porous web for filtering fluids has a plurality of adjacent layers of fiber material having anisotropic properties. The anisotropic directions of a given vectorial property of at least two adjacent layers differ one from the other by an angle greater than 0°, and preferably of at least 8°. The porous web is particularly useful as a filter element for the filtration of biological fluids, such as blood and blood components.

  • Patent number: 7775376
    Abstract: The invention relates to a filter for the separation of leukocytes from whole blood, comprising a hydrophobic support material and a polymeric coating material, whereby the surface of the filter has a critical surface wetting tension in the range 50 to 80 dyn/cm and the polymeric coating material may be obtained by polymerisation reaction of mixtures comprising hydrophobic and hydrophilic monomers. The invention further relates to a method for production of said filter and devices for the separation of leukocytes from whole blood and the use of the filter.

  • Patent number: 7351344
    Abstract: The invention relates to a sterile system and a method for filtering biological or medical liquids, especially blood or blood constituents. According to the filtering system and method, the sterile air already in the system is collected before the beginning of the filtration process, and after the filtration process, in order to completely empty the system used. Said filtering system comprises a collapsible container having a first and second air inlet/outlet line. The first air inlet/outlet line communicates with the first chamber of the filter by means of a flow connection, and the second air inlet/outlet line with the second chamber of the filter. Only the air inlet/outlet line communicating with the first filter chamber is sealed by a hydrophobic membrane or a return valve in the filtering system, such that the system has an especially simple structure.
