Abstract
A material for forming an organ model containing an aqueous gel, which comprises polyvinyl alcohol having an average degree of polymerization of 300 to 3500 and a degree of saponification of not less than 90% by mole, and silica particles; a method for producing a material for forming an organ model, comprising cooling an aqueous polyvinyl alcohol solution which contains polyvinyl alcohol having an average degree of polymerization of 300 to 3500 and a degree of saponification of not less than 90% by mole and silica particles, to a temperature of −10° C. or lower, and thawing the resulting formed aqueous gel; and an organ model at least provided with a surface layer comprising the material for forming an organ model. Thus, it is possible to provide: an organ model which has a hydrophilic property similar to an organ of a human body, gives such an incision feel that an incised portion spreads just similar to a living human organ and, therefore can be appropriately used in, for example, exercising surgical procedures; a material for forming an organ model appropriately usable for the organ model; and a method for producing the same.
