Abstract: An artificial bone forming method, comprising a) a powder layer forming step (32) for forming, into a flat powder layer (6), a powder bone material (5) having biocompatibility and hardening by hydration, b) a partial hardening step (34) for jetting an aqueous solution (7) with biocompatibility to a part of the powder layer to harden a jetted portion (6a) by hydration, and c) an artificial bone forming step (36) for repeating the steps a) and b) for lamination to form a specified artificial bone (9) of a predetermined three-dimensional structure in which the hardened portions (6a) are connected to each other.

Abstract: An object of the present invention is to provide a tissue cell culture system whereby a call tissue can be efficiently and quickly proliferated in vivo and the onset bacterial infection in an injured part can be avoided in the course of a treatment. More specifically, a closed cell culture system (1) characterized in that a defection (2) of a tissue on the body surface or inside the body is tightly sealed to form a closed environment free from the invasion of bacteria, etc. and then a solution appropriate for cell culture is circulated in the tissue defection thus sealed to thereby regenerate the defective tissue; and a method of administering a drug which comprises dissolving a remedy in the perfusion with the use of the above system and thus promoting the treatment of the defection.

Abstract: A hemostatic material insertion device is provided for simplifying hemostasis of the puncture wound in a blood vessel. The device comprises a cartridge charged with hemostatic material, a hollow sheath which holds the cartridge, an ejecting piston portion which forms one unit with the sheath at the rear end of the sheath and is used for pushing out the hemostatic material charged in the cartridge, a guide knob to slide the cartridge inside the hollow sheath and a stopping device affixed to the front end of said hollow sheath. Further, methods of using a hemostatic material insertion device are provided.
