Structure and transport properties of the Ultracell membrane for hemodialysis.

Particular features of structure and transport properties of a new Soviet-made hydrate cellulose membrane Ultracell have been studied. The membrane has a structure of a swollen gel with well defined macropores that ensures high effectiveness in convectional transport of substances across the membrane. In view of the above the Ultracell membrane may be used both for conventional hemodialysis and also for hemodialysis with simultaneous or consecutive ultrafiltration aimed at removing the excessive water and metabolites with middle molecular weight.
