HOLLOW FIBER MEMBRANE TYPE BLOOD PURIFIER |
摘要 |
<p>A hollow fiber membrane type blood purifier packed with hollow fiber membranes comprising a polysulfone resin and polyvinylpyrrolidone. Even when sterilized by irradiation with a radiation, the hollow fiber membrane type blood purifier is less apt to suffer polyvinylpyrrolidone dissolution and can be inhibited from decreasing in blood compatibility. The purifier is of the type called semidry, and is lightweight and has excellent handleability. The hollow fiber membrane type blood purifier comprises a bundle of hollow fiber membranes comprising a polysulfone resin and polyvinylpyrrolidone, a container packed therewith, and a potting agent disposed between each bundle end and the container to hold the bundle and thereby form a hollow-fiber-membrane inside chamber and a hollow-fiber-membrane outside chamber. The purifier has fluid ports connected to the hollow-fiber-membrane inside chamber and a fluid port connected to the hollow-fiber-membrane outside chamber. The hollow fiber membrane type blood purifier is characterized in that the hollow fiber membranes have, adherent thereto, a radical trapping agent in an amount of 80-300% based on the dry weight of the hollow fiber membranes, have a water content of 40-100%, excluding 100%, and have been sterilized with a radiation.</p> |
