The present invention is a connector to be provided on way of a blood restoring circuit of a plasmapheresis bag set, comprising a male connecting member and a female connecting member. Each of the members is provided with a key ring of a structure in laminated layer, and the key rings are formed, at ends with a convex or a groove for having combination of the both members. The connecting members are provided with positioning means therefor, and positionings of the convex or the groove of the key rings are adjusted per each of the connectors.

Connector for plasmapheresis bag

The invention provides a blood treatment apparatus realizing double-step-membrane filtration, namely separation of blood into plasma and a corpuscular fraction and separation of high-molecular-weight substances (e.g. gamma-globulin) in the plasma from low-molecular-weight substances (e.g. albumin). A method of treating blood is also provided. The apparatus and method are effective e.g. in the treatment of blood of patients with peripheral circulatory insufficiency due to arteriosclerosis and of patients with rheumatoid arthritis, which is an autoimmune disease.
