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.

A freezing vessel for fabricating frozen fine liver pieces for an artificial liver comprising: an essentially solid, unperforated cover unit formed of a ceiling plate and a peripheral side wall, the ceiling plate including an upper coupling port extending through the ceiling plate and capable of being selectively coupled with a first coolant flow conduit, or closed by a first plug for transport purposes, the cover unit also including a mesh plate for preventing movement of the fine liver pieces out of the vessel through the upper coupling port, and the peripheral side wall being formed with a lower coupling portion, at least one solid, unperforated hollow coupling cylinder unit including an upper coupling portion selectively detachable from or rigidly connectable to the lower coupling portion of said cover unit, and including a lower coupling portion, and an essentially solid, unperforated bottom unit formed of a bottom plate and a peripheral side wall, the bottom plate including a lower coupling port extending through the bottom plate and capable of being selectively coupled with a second coolant flow conduit, or closed by a second plug for transport purposes, and the peripheral side wall including an upper coupling portion selectively detachable from or rigidly connectable to the lower coupling portion of an adjacent one of the coupling cylinder units; and at least one of the coupling cylinder units or the bottom unit including a laterally positioned mesh plate for supporting the fine liver pieces in the vessel.
