Abstract: A blood collection system has a container for holding blood and a filter communicating with the container, mutually arranged for handling as a unit. The filter (20) contains a fibrous filter medium (28) housed within two flexible sheets (32, 34) of plastic. A first seal (36) joins the sheets (32, 34) directly to the filter medium (28) inboard of the peripheral edge (40) of the filter medium (28), and a second seal (38) joins the sheets (32, 34) outboard of the peripheral edge (40) of the filter medium (28). A region (42) of the filter medium (28) extends between the first and second seals (36, 38) to cushion contact with the filter housing during handling.

Abstract: A flexible, three-dimensional container is made by a prescribed vacuum-molding and heat sealing process. The container possesses a precise, defined geometry before and during use. The container is formed from first and second walls. The first wall has a planar area and a vacuum-molded cavity area drawn out of the plane of the planar area into a predefined three-dimensional geometry. A second wall overlies the first wall to close the cavity area and thereby forms an interior compartment. A thermal seal joins the two walls together. The seal is formed by heating the second wall and the first wall in the planar area, while assuring that the cavity area of the first wall is not subject to heating and possible deformation of its precise vacuum-molded geometry.

Abstract: A port is formed in a thermoplastic container wall by slitting the wall, inserting a thermoplastic tube through the slit, placing a mandrel in the tube, placing opposed dies defining a bore over the sheet and tube, and dielectrically heating the thermoplastic to fuse the tube and sheet. Preferably the bore defined by the dies is of a diameter slightly less than that of the tube, and has an enlarged central area which forms a thickened section of material over the slit.

Abstract: A port (20) is formed in a thermoplastic container wall (22) by slitting the wall (22), inserting a thermoplastic tube (26) through the slit (24), placing a mandrel (34) in the tube, placing opposed dies (30, 32) defining a bore over the sheet (22) and tube (26), and dielectrically heating the thermoplastic to fuse the tube (26) and sheet (22). Preferably the bore defined by the dies (30, 32) is of a diameter slightly less than that of the tube (26), and has an enlarged central area which forms a thickened section (40) of material over the slit (24).

Abstract: A fluid filter assembly (10) for filtering fluids such as blood includes fir st and second filter housing elements (20, 22) formed by an injection molding process. Each element (20, 22) is flexible and includes a peripheral flange (24) formed thereabout and a fluid communicating port (40) formed therein. Filter media, such as a filter membrane, is sealed between the mating flange s (24) of two elements (20, 22). The fluid filter assembly (10) is capable of collapsing and expanding during the filtration process depending upon the composition of the fluid passed therethrough. A method of making the filter assembly (10) and systems for using the filter assembly (10) are also described.

Abstract: A method of making a blood filter assembly provides first and second filter housing elements from a flexible thermoplastic material, each of the first and second housing elements including a molded port. The method places a filter media between the first and second filter housing elements and applies radio frequency heating and pressure to form a peripheral seal that joins the first and second filter housing elements to the filter media and encapsulates the filter media between the first and second housing elements.

Abstract: A container has first and second walls, each formed of a thermoplastic sheet having a peripheral edge. A peripheral seal joins the peripheral edges together to form an interior chamber enclosed by the first and second walls. A port communicates with the interior chamber. The port is spaced from and does not extend through the peripheral seal. The port comprises a hollow thermoplastic tube, which extends through a slit in one of the first and second sheets and is oriented tangentially thereto. The slit is fused by heat about the tube, forming a heat fused junction. A medical product or a blood filter material can be housed in the interior chamber.
