A filter assembly comprising a prefiltering support layer () is disclosed, wherein the prefiltering support layer () comprises a non-woven fabric of fibers, the non-woven fabric having a pore size. A first mesh filter layer () is arranged downstream the prefiltering support layer (), wherein the first mesh filter layer () has a first mesh size, wherein the pore size of the prefiltering support layer () is equal to or bigger than the first mesh size of the first mesh filter layer (). A container for collecting a body fluid comprising such a filter assembly as well as a method for manufacturing such a filter assembly are also disclosed.

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.

Filter assemblies are processing biological fluid, such as blood or a blood component containing leukocytes. The filter assemblies include a flexible housing with first and second walls. A filtration medium and a support member are at least partially positioned between the walls of the housing, with a seal joining the walls of the housing, the filtration medium, and the support member. The filter assemblies may further include a pre-filter and/or a post-filter positioned between the walls of the housing. If provided, the pre- and post-filter may be positioned on opposite walls of the filtration medium, with the post-filter being a mesh positioned between the filtration medium and one of the walls of the housing or within an opening defined by the support member. A seal of the filter assembly may pass through the filtration medium, with the filtration medium being substantially omitted in a section of the seal.

Flexible biological fluid filters

Flexible housing filters for filtration of fluids and methods of making such filters are disclosed. The filters may include one or more peripheral seals in the flexible housing.

Devices for the removal of cells or other particles from a biological fluid are disclosed. The devices include a removal medium housed within a chamber of a housing. The devices include inlet and outlet ports carried by the walls. One or both of the ports includes a flow path portion having a chamber-communicating portion that has a cross-section that is larger than the cross-section of an adjacent flow path portion.

Blood filter

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&#xb0;, and preferably of at least 8&#xb0;. The porous web is particularly useful as a filter element for the filtration of biological fluids, such as blood and blood components.

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.
