Abstract: An artificial blood has a trunk portion with both ends connected to blood vessels, and access branch portions and a shunt branch portion branched from the trunk portion. The access branch portions are disposed with a solid column-shaped access port that plugs these branch portions. The access port has a solid center portion and a tube-shaped peripheral portion disposed to surround the center portion. The peripheral portion is harder than the center portion and prevents the needle from deviating from the inside of the center portion. This enables a puncture to be easily made in a therapy in which a puncture is highly frequently made in a blood vessel.

Abstract: A method for manufacturing a hydrocarbon oil, comprising: a first step wherein a feedstock oil containing an oxygen-containing organic compound and a water-insoluble chlorine-containing compound is brought into contact with a hydrogenation catalyst comprising a support containing a porous inorganic oxide and one or more metals selected from Group VIA and Group VIII of the periodic table supported on the support in the presence of hydrogen to generate a hydrocarbon oil and water in a vapor state by the hydrodeoxygenation of an oxygen-containing organic compound and convert the water-insoluble chlorine-containing compound into a water-soluble chlorine-containing compound; a second step wherein the water in the reaction product of the first step is maintained in a vapor state and the reaction product of the first step is brought into contact with a nitrogen-containing Brønsted base compound which has a boiling point at normal pressure of 100° C.

Abstract: An artificial blood vessel has a trunk portion which forms a part of the blood vessel and also has branch portions which are branched from the trunk portion. The branch portions are provided with access ports into which a needle, for discharging liquid out of a human body or introducing the liquid into the human body, is inserted. Tubular reinforcement members integrated with the blood vessel wall of the trunk portion are disposed at positions of the trunk portion, the positions being those from which the branch portions are branched, and at portions adjacent to the positions of the trunk portion. A lateral force at the time of needle insertion is borne by the reinforcement member, and this prevents the trunk portion from deforming. Thus, the configuration prevents the artificial blood vessel from deforming due to a force applied when a needle for discharging liquid from a human body or introducing the liquid into the human body is inserted into an access port of the artificial blood vessel.
