Abstract

Membrane separation technology using the polymer has been applied above all. The artificial kidney is one of the things which industrially grew and succeeded most, the number of dialysis patients has exceeded 200000 in 2000 year-ends for the advance of hemodialysis.<BR>Originally, a membrane means the biomembrane, and the organism maintains the life by the skillful membrane mechanism. It will be reasonable outcome to introduce the membrane separation technology into medical field, in the medical purpose to attempt the recovery of damaged biofunction.<BR>Regrettably, the practical artificial membrane that has produced does not have the advanced function like the biomembrane. In the present state, that is applied in the medical field as an extension of membrane separation technology in the conventional industry field. In short, it is merely the physical separation membrane for the material separation using selective permeability by the interaction at most, of spatial size, between solute and membranogen material.<BR>However, the peculiarity of using under the organism environment certainly must be considered in case of the medical application. The defense reaction of the organism works by the contact between blood and separation membrane which is foreign body for the organism. The degree of this reaction is called the biocompatibility, and they are important with the separation characteristics in the design of a membrane.
