    • 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. Further, as the bundle is protected by the casing, the fibers will hardly break or hardly slip out of the bundle, even though a forced current of the dialyzate is applied thereto. Therefore, the dialysis can be carried out in a short time with high security.
    • 透析单元和使用透析单元的透析装置,其可以以非常高的效率进行透析。 该单元包括大量基本相等长度的多个半透水中空纤维,该纤维被聚集形成束并且在其两端部处以液密连接结合。 这束中空纤维被松散地封装在具有基本上均匀分布在整个壳体上的多个开口的壳体中。 将透析单元放入透析液中,其中具有用于产生透析液的强制电流的装置。 透析液通过开口流入壳体,并从各个方向作用于中空纤维束。 因此,即使在束的内部部分,透析液可以自由地在束内部和外部流动,同时保持透析液与纤维表面之间良好的接触。 此外,由于束被壳体保护,所以即使将透析液的强制电流施加到其上,纤维几乎不会破裂或几乎不脱离束。 因此,透析可以在短时间内进行,安全性高。
