Patent number: 4075100Abstract: A dialysis unit and a dialysis apparatus employing the dialysis unit which can perform dialysis at a very high efficiency. The unit comprises a vast plurality of semi-permeable hollow fibers substantially equal in length, which fibers are gathered to form a bundle and bonded in liquid-tight connection at both ends portions thereof. This bundle of hollow fibers is loosely encased in a casing having a plurality of openings substantially uniformly distributed all over the casing. The dialysis unit is put in a dialyzate bath having therein a means for making a forced current of the dialyzate. The dialyzate flows into the casing through the openings and acts upon the bundle of hollow fibers from all directions. Accordingly, the dialyzate can flow freely inside and outside the bundle, while maintaining good contact between the dialyzate and the surfaces of the fibers, even in the inner portion of the bundle.Type: GrantFiled: December 2, 1975Date of Patent: February 21, 1978Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Tadaaki Furuta, Kenji Inagaki, Yoshiyuki Mizoguchi, Noboru Fujikawa, Naoya Kominami
