Patent number: 11759998Abstract: An object of the present invention is to provide a method for producing a gelatin formed body having a minimized content of a component harmful to a living body and high biocompatibility with high shaping accuracy, and a gelatin formed body produced by the method. According to the present invention, provided is a method for producing a gelatin formed body, the method including: a step a of forming, on a substrate, a layer containing a powder which is obtained by air-drying an aqueous gelatin solution and has an average particle diameter of 25 to 200 ?m; and a step b of jetting liquid droplets of an aqueous solution containing alcohols having a boiling point of 120° C. or lower toward the layer formed in the step a from a nozzle and flying the jetted liquid droplets so that the liquid droplets are landed on the layer formed in the step a, thereby forming a gelatin formed body.Type: GrantFiled: December 7, 2018Date of Patent: September 19, 2023Assignee: FUJIFILM CorporationInventors: Manabu Katsumura, Takahiro Hiratsuka, Hideo Fushimi, Yoshio Ishii, Ai Okamura, Hiroshi Ota, Jun Arakawa

Patent number: 10960106Abstract: A tissue repair material includes gelatin granules, and the tissue repair material exhibits a water absorptivity of 800% by mass or more, and a residual ratio of 60% by mass or less after three hours of decomposition treatment using 1 mol/L hydrochloric acid. A block-shaped tissue repair material includes gelatin, and the block-shaped tissue repair material exhibits a water absorptivity of 800% by mass or more, and a residual ratio of 60% by mass or less after three hours of decomposition treatment using 1 mol/L hydrochloric acid.Type: GrantFiled: August 28, 2015Date of Patent: March 30, 2021Assignee: FUJIFILM CorporationInventors: Izumi Nakahara, Hideo Fushimi, Takahiro Hiratsuka, Ai Okamura, Shoji Oya, Hidekazu Sakai, Yoshitaka Oono

Patent number: 10953131Abstract: Provided are a method for rapidly producing a calcium phosphate molded article having high strength with high shaping precision, a calcium phosphate molded article produced by the method, and a material for transplantation. Disclosed is a method for producing a calcium phosphate molded article, the method including: step (a) of forming a layer containing a calcium phosphate powder having a ratio of the numbers of atoms of Ca/P of 1.4 to 1.8 on a substrate; and step (b) of producing a calcium phosphate molded article by jetting an organic acid solution having a pH of 3.5 or lower and including an organic acid whose calcium salt has a solubility in water of 1 g/100 mL or less, through a nozzle unit into a liquid droplet state, thereby dropping the organic acid solution onto the layer containing a calcium phosphate powder formed in step (a).Type: GrantFiled: November 29, 2018Date of Patent: March 23, 2021Assignee: FUJIFILM CorporationInventors: Hiroshi Ota, Manabu Katsumura, Kazuya Kawasaki, Yoshio Ishii, Hideo Fushimi, Takahiro Hiratsuka, Ai Okamura, Mamoru Nishitani, Masayuki Ezumi
