hemoperfusion device using the active carbon is spherical and method of purification of the blood by means of this device

摘要

A method and apparatus for hemoperfusion comprising a vessel packed with a spherical active carbon having pores of substantially not larger than 500 ANGSTROM in radius, said spherical active carbon being produced by polymerising an ethylenically unsaturated aromatic compound, making the resulting spherical polymer infusible, calcining the resulting infusible polymer and activating, and the use thereof. The apparatus is useful for the treatment of patients with chronic renal failure, acute intoxication, liver failure, hepatoreal syndrome or the like, particularly as an artificial kidney.
