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.

Device for cross flow filtration

Device for whole blood cross flow filtration using a cannula needle

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.

Blood filtering device

A filter element for filtering liquids has a folded filter medium with outer fold edges and inner fold edges, wherein the inner and outer fold edges extend along a longitudinal axis of the filter element. A support body is provided with a first support body section and a second support body section, wherein the first support body section is facing the inner fold edges and hugs closely an envelope of the inner fold edges. An envelope of the outer fold edges and the second support body section hug closely at least sectionwise an outer circumferential surface of the filter element.

Filter element and filter arrangement

A filter element is provided with a folded bellows that has a first pleated section with parallel arranged first pleats and a second pleated section with parallel arranged second pleats. The first pleats of the first pleated section are positioned at an angle relative to the second pleats of the second pleated section. The end face edges of the first pleats of the first pleated section adjoin a first clean chamber. The end face edges of the second pleats of the second pleated section adjoin a second clean chamber. The second clean chamber is delimited by a longitudinal side of an edge-side pleat of the first pleated section. The first and second clean chambers are connected to each other. A filter insert with such a filter element is provided.

Pleated filter element

A filter insert piece has a filter element with first and second pleated sections each having parallel pleats. The first and second pleated sections each have an inflow side. A first flat outflow side of the first pleated section and a second flat outflow side of the second pleated section adjoin a common clean chamber of the filter element. A length of the pleats of the first and second pleated sections is such that a spacing of an outwardly positioned pleat end face of the pleats at the first or second inflow side, respectively, relative to the center axis increases or decreases monotonic from pleat to pleat. The respective end pleats of the first and of the second pleated sections have a different length extension measured from the outwardly positioned pleat end face of the first end pleats or the second end pleats relative to the center axis.

Filter insert piece comprising a pleated filter element

A filter element has a filter medium with a first end and a second end in an axial direction of the filter medium. A first end disk is connected to the first end and has an outflow opening. A second end disk is connected to the second end and has an engaging section, wherein the engaging section engages a counter engaging section of a filter housing of the filter element such that the filter element is received, secured against rotation, in the filter housing. The second end disk is provided with an aperture.
