Method of fabricating frozen fine liver piece for artificial liver.

摘要

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 (26) for pressurizing liquid helium (20) coupled to a chamber (21) for storing the liquid helium (20), a helium gas conduit (24) dipped in the liquid helium (20) passed through the chamber (21) to allow the conduit to communicate with a freezing chamber (22) to be closed and contained, to which the liver fine pieces are telescopic, and an exhaust conduit (29) provided with a control valve (30) coupled to the freezing chamber (22). And, a freezing vessel (44) for an artificial liver which has a flow conduit capable of being coupled to an upper portion and a lower portion of an unit, an upper coupling port and a lower coupling port respectively formed therethrough to close plugs, two or more mesh plates laterally laid elevationally in the unit, an exit opened corresponding to a containing chamber thus formed.
