    Abstract: A blood filter device has a housing that includes: a head portion (2) provided with a blood inlet (5) and forming an upper structure of the housing, a filtration portion (3) positioned below the head portion and forming a middle structure of the housing, and a bottom portion (4) disposed below the filtration portion and provided with a blood outlet (7); and a filter (8) mounted in a cavity of the filtration portion and partitioning a cavity of the housing into a head portion side and a bottom portion side. The filter is formed of a filter sheet folded to have a plurality of pleats, and disposed so that ridgelines of the plurality of pleats traverse respectively the cavity of the filtration portion in parallel. The bottom portion has a conical portion (4a) on the inner bottom face protruding downward to form a conical face. Due to the conical portion of the bottom portion, resistance against blood passing through the housing interior is reduced, and the pressure loss can be suppressed satisfactorily while maintaining sufficient filtration performance of the filter in a small device.

    Abstract: The present invention relates to a fibrous pad structure having a variable density. The continuous strip-shaped webs are sliced and rubbed to form one or more continuous strip-shaped webs that are separated from each other by a constant distance. The strip-shaped webs can also be spread and lapped onto a continuous smooth fibrous web in a regular arrangement. The combined fibrous webs are corrugated and shaped into a vertical porous fibrous pad. Such a fibrous pad has a different density distribution in the transversal cross section and a continuous corrugated structure in the mechanical direction. The density of the combined fibrous pad in accordance with the present application can be adjusted according to the uses of the fibrous pad. The mechanical properties of the products made from the fibrous pad thus are adjustable to meet the requirements of different uses of the product.

    Abstract: A filter for a fluid system includes a housing having an interior cavity. A filter media is disposed in the housing and defines a central opening. A center tube assembly is arranged within the central opening and includes discs which are stackable upon one another. Each disc includes a central portion having base received by an inner wall of the central portion of the adjacent disc. An outer portion extends radially outwardly from the central portion and is positioned adjacent to the filter media. The central portion, base, and outer portion may include openings to permit the flow of fluid through the center tube assembly. The center tube assembly provides the desired structural integrity while permitting fluid to flow through the center tube. The present invention center tube assembly may be produced by a plastic molding process.
