Document Type and Number:
Japanese Patent JP6622158
Kind Code:
B2
Abstract:
A medicine-holding body (35) is disposed in a flow path (27) of a nozzle portion (19) of an adapter for blood dispensing (12). The medicine-holding body (35) is formed of a plurality of fibers (40) which is made of polyester and is bundled by aligning a longitudinal direction thereof in a flowing direction (DF) which is a direction in which blood flows. The medicine-holding body (35) holds an anticoagulant (41) for suppressing coagulation of blood, as a medicine to be mixed into blood. The surface area of the medicine-holding body (35) is greater than or equal to 10 mm 2 and less than 600 mm 2 . In a case where the surface area of the medicine-holding body (35) is greater than or equal to 10 mm 2 , 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 (35) is less than 600 mm 2 , it is possible to maintain the occurrence rate of hemolysis to be less than or equal to 10%.
