ABSTRACT:
A method of fabricating frozen fine liver pieces for an artificial liver which comprises cutting a liver removed from a human being or an animal, from which blood is removed into fine pieces of square shape and freezing the liver pieces with helium gas. A freezing apparatus for an artificial liver which has gas phase pressurizing means for pressurizing liquid helium coupled to a chamber for storing the liquid helium, a helium gas conduit dipped in the liquid helium passed through the chamber to be closed and contained, in which the liver fine pieces are telescopically received and an exhaust conduit provided with a control valve coupled to the freezing chamber. And, a freezing vessel for an artificial liver which has a flow conduit capable of being coupled to an upper portion and a lower portion of a unit, an upper coupling port and a lower coupling port respectively formed therethrough with closing plugs, two or more mesh plates laterally laid elevationally in the unit, and exit opening in to a containing chamber thus formed.
