Abstract: A medicine-holding body is disposed in a flow path of a nozzle portion of an adapter for blood dispensing. The medicine-holding body is formed of a plurality of fibers which is made of polyester and is bundled by aligning a longitudinal direction thereof in a flowing direction which is a direction in which blood flows. The medicine-holding body holds an anticoagulant for suppressing coagulation of blood, as a medicine to be mixed into blood. The surface area of the medicine-holding body is greater than or equal to 10 mm2 and less than 600 mm2. In a case where the surface area of the medicine-holding body is greater than or equal to 10 mm2, the concentration of the anticoagulant becomes greater than or equal to a lower limit value of 10 U/mL even under most severe conditions such as a dispensing speed of 500 μL/second. In a case where the surface area of the medicine-holding body is less than 600 mm2, it is possible to maintain the occurrence rate of hemolysis to be less than or equal to 10%.
