摘要： Embodiments of the invention pertain to cartridges, systems and methods for performing hemodialysis and related extracorporeal blood treatment modalities and therapies, in which blood flows in the inter fiber space and dialysate flows in the lumens of hollow fibers. Appropriate connectors and fitting orientations may be provided. There may be provided orbital distributors, fanning of fibers, and features to promote uniformity of fiber spacing in the fiber bundle. Orbital distributors may contain contoured surfaces, flow redirectors, non-uniform-conductance flow elements, through-wall distributors, and other features. There may be subdivision of the fiber bundle into two groups of fibers with separate control fluid to each group. Appropriate systems may be provided for various therapies. Flow past the fibers may be parallel, transverse or other configuration. These various features may enable long-term application to all dialysis and ultrafiltration related therapies, and also to other therapies and to applications including implantables, portables and wearables.

摘要： The invention relates to the providing of hydrophobic and hydrophilic polymer-based hollow fiber membranes containing a water-insoluble antioxidant; in particular, the invention relates to the providing of hollow fiber membranes for the extracorporeal treatment of blood, wherein the hollow fiber membranes have improved biocompatibility relative to treatment blood, in particular improved complement activation and lower platelet loss vis-à-vis treatment blood. At the same time, the elution of hydrophilic polymers from the lumen of the hollow fiber membrane is reduced.

摘要： A biogas combustion system that obtains a stable output and saves energy is realized. A combustion system comprises a separation portion 14 that removes carbon dioxide from a treatment target gas containing a mixture gas containing methane as a main component and containing carbon dioxide to obtain methane gas of a high purity in which at least a content of carbon dioxide has been reduced, and a combustion portion 15 that combusts the methane gas. The separation portion 14 includes a first treatment chamber 11 and a second treatment chamber 12 separated from each other by a separation membrane 13 therebetween. The separation membrane 13 selectively allows the carbon dioxide in the treatment target gas supplied to the first treatment chamber 11 to pass therethrough to the second treatment chamber 12 to obtain a first separation gas having a higher methane purity than the treatment target gas in the first treatment chamber 11 and a second separation gas containing the carbon dioxide in the treatment target gas in the second treatment chamber 12.

摘要： A liquid membrane 100 is formed by jetting a liquid sucked from a recovery reservoir 11a and pressurized using a pump 12 from a nozzle of a liquid membrane cartridge 20. The formed liquid membrane 100 makes contact with a slope wall of the liquid membrane cartridge 20 along a surface of the liquid membrane 100. The liquid running down from the slope wall is recovered and stored in the recovery reservoir 11a in order to recover the liquid running down along the slope wall in a decelerated state into the recovery reservoir 11a. As a result, it is possible to prevent air bubbles from being generated by agitation of a liquid of the recovery reservoir 11a when the liquid enters the recovery reservoir 11a.

摘要： Additively manufactured ceramic filters are disclosed. A plurality of pores, each having a uniform geometry, are arranged between an inlet surface and an outlet surface of a single unit of ceramic such that the plurality of pores change in size uniformly from the inlet surface to the outlet surface. The pores are respectively interconnected, and the size, shape, orientation, and/or interconnection of the pores are chosen to provide hydrodynamic features that provide effective filtration for a given liquid and contamination. The pores are additively manufactured with optimized precision.

摘要： A waterproof member (20) includes a first adhesive layer (22), a second adhesive layer (24), and a porous layer (26). The porous layer (26) is disposed between the first adhesive layer (22) and the second adhesive layer (24). The first adhesive layer (22) and the second adhesive layer (24) each have a frame shape in plan view. When the first adhesive layer (22), the second adhesive layer (24), and the porous layer (26) are seen in plan view, the outer boundary of the porous layer (26) lies within the outer boundary of the first adhesive layer (22) and the outer boundary of the second adhesive layer (24). The first adhesive layer (22) is bonded directly to the second adhesive layer (24) in a region outside the outer boundary of the porous layer (26). The porous layer (26) has a peripheral surface that is shielded from outside by the first adhesive layer (22) and the second adhesive layer (24).

摘要： A novel positive traction permeate tube and fittings therefor are described for use in spirally wound membrane filtration elements for filtration and separation applications. Membrane filtration elements incorporate the novel permeate tube. Methods of making the novel positive traction permeate tube are also disclosed, as are the preferred sanitary stainless steel materials used for the sanitary tube and fittings. The novel permeate tube involves a sanitary tubing having two open ends, each with an end fitting. The end fittings engage a positive traction drive for high tension spiral winding of a membrane element spirally around the novel permeate tube. Membrane filtration elements made with the novel permeate tube are less subject to slippage and breakage during manufacture and can withstand higher pressure drops and flow rates during use without failure of the spirally wound membrane element. The positive traction permeate tube facilitates membrane replacements.
