FILTER MATERIAL FOR REMOVING AGGREGATES AND METHOD OF FILTERING BLOOD PREPARATION |
摘要 |
<p>An aggregate-removing filter material efficiently removes aggregates that are contained in a blood product for transfusion and may cause transfusion reactions without clogging, and exhibits excellent quality stability, and a blood product filtration method uses a filter apparatus that includes the aggregate-removing filter material and a leukocyte-removing filter material. The aggregate-removing filter material includes short fibers having a fineness of 0.7 to 4.0 dtex and a fiber length of 1 to 80 mm, and a ground fabric that includes long fibers, a fiber axis of the long fibers being oriented in a planar direction of the ground fabric, the short fibers being entangled with the ground fabric so that the aggregate-removing filter material has a total weight per unit area of 10 to 80 g/m 2 , and a layer of the short fibers forming a three-dimensional structure.</p> |
