Abstract: [Problem] To provide a resin composition that can lead to a biological model, which has a softness and provides a sensation of needle insertion close to those of human blood vessels and/or skin, and a biological model using the same.
[Solution] A resin composition containing, with respect to 100 parts by mass of a component (A) hydrogenated block copolymer having a MFR (temperature 230° C., load 2.16 kg) of 1 g/10 min or less: 350 parts by mass or more and 1000 parts by mass or less of a component (B) oil; and 0.01 parts by mass or more and less than 150 parts by mass of a component (C) lubricant. The component (B) oil preferably has a kinematic viscosity of 0.1-100 mm2/s at 37.8° C. or 40° C.

Abstract: [Problem] To provide a softer resin material that can be highly filled with an oil and that has almost no seepage (bleed-out) of oil. Additionally, to provide a biological model that is easy to handle and that has a softness and mechanical properties closer to those of organs and a texture close to that of organs. [Solution] A resin composition containing 100 parts by mass of component (A), a hydrogenated block copolymer having an MFR (measured at a temperature of 230° C. and with a load of 2.16 kg) of 1 g/10 min or less; more than 1000 parts by mass and at most 2000 parts by mass of component (B), an oil; and at least 10 parts by mass and at most 120 parts by mass of component (C), a polyolefin resin having a specific surface area of 0.01 to 30 m2/g.

Abstract: By using CNF excellent in dispersibility, conductivity, and crystallinity, a conductive polymer material having high conductivity even with a low CNF content and a shaped article thereof and a conductive polymer material with a less CNF content for same conductivity and a shaped article thereof are provided. A conductive polymer material with high conductivity is produced by using carbon nanofiber with a median diameter D50 value from 0.1 to 8 μm, powder resistivity of 0.03 Ωcm or less measured under a load of 9.8 MPa, and D/G from 0.5 to 1.3.

Abstract: An artificial blood vessel that gives a sensation of needle insertion upon puncturing and a needle thread passability resembling those of blood vessels of animals including humans, and that has high liquid leakage preventability includes two or more layers which contain a component (A) hydrogenated block copolymer and a component (B) oil, at least one of the layers further containing a component (C) lubricant. It is preferable that the artificial blood vessel has a first peak load value of 0.01 N or more and 1.2 N or less upon needle penetration by puncturing at a speed of 1000 mm/min. under the condition of 23° C.±1° C. using a universal testing machine.

Abstract: Disclosed is an ulcer model used to practice a procedure including hemorrhage arrest, the ulcer model including a model main body which includes upper and lower surfaces facing each other and a tubular simulated blood vessel path provided between the upper surface and the lower surface and having an inlet opening and an outlet opening. The upper surface includes a ring-shaped raised surface that rises in a thickness direction of the model main body and a simulated ulcer surface that is a recessed bottom surface surrounded by the raised surface. The simulated blood vessel path extends from a part other than the upper surface of the surfaces of the model main body to the simulated ulcer surface or an area in the vicinity of the inside thereof.
