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.

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

An air filter element () for insertion into an air filter housing, comprising an intake surface (), a discharge surface (), a filter medium (), and a filter element-retaining device () which extends along at least a section of the periphery of the filter medium (), between the intake surface () and the discharge surface (), and which includes a retaining arrangement () that radially projects from the filter medium ().

Air filter element having a specific retaining geometry

A filter element of a filter system for filtering fluids has a filter medium with end faces. Terminal bodies, one each, are connected to one of the end faces of the filter medium, respectively. A support body extends between the terminal bodies. A first terminal body is connected by a toothed connection to the support body for transmitting a torque from the first terminal body onto the support body and from the support body onto the first terminal body.
