| 20100133170 | POLYSULFONE-BASED BLOOD TREATMENT MEMBRANE AND METHOD OF PRODUCING THE SAME - A polysulfone-based blood treatment membrane that exhibits excellent antioxidant properties, excellent long-term storage stability, and a practical strength, and ensures high productivity, a polysulfone-based blood treatment membrane that exhibits excellent antioxidant properties and long-term storage stability, rarely allows endotoxins to enter a treatment liquid, exhibits a practical strength, and ensures high productivity, and a method of producing the same. A polysulfone-based blood treatment membrane includes a polysulfone-based resin, a hydrophilic polymer, and a lipophilic antioxidant, the membrane containing the lipophilic antioxidant in an amount of 30 to 76 mg per gram of the membrane, and the total amount of the lipophilic antioxidant present on the surface of the membrane being 4 to 25 mg per gram of the membrane. Another polysulfone-based blood treatment membrane contains a lipophilic antioxidant in an amount of 30 to 76 mg per gram of the membrane, wherein the inner surface of the membrane has a TOF-SIMS normalized peak intensity of the lipophilic antioxidant of 1.8×10 | 06-03-2010 |
| 20100258496 | POROUS HOLLOW FIBER MEMBRANE FOR TREATING BLOOD - It is intended to provide a porous hollow fiber membrane for treating blood which suffers from little mechanical damage in the course of production, transfer or handling and shows excellent fractionation properties though it is a thinned polysulfone-based hollow fiber membrane. A porous hollow fiber membrane for treating blood which comprises a polysulfone-based polymer and polyvinylpyrrolidone and has a gradient porous structure with an increase in pore size from the inside to the outside along the membrane thickness direction, characterized in that the porous structure has a membrane thickness of 25 μm or more but less than 40 μm, and fibrils having an average diameter of from 100 to 200 μm are provided in such a manner that the ratio (To/Ti) of the average outside diameter (To) along the membrane thickness direction to the average inside diameter (Ti) is adjusted to not more than 2. | 10-14-2010 |
