Abstract
A cylindrical body (30) that is inserted into a drug solution container (70), a connection port (15) to which a syringe (40) is connected, and a connector (50) that is connected to a port (110) of an infusion bag (100) communicate with a cavity (11) of a delivery device main body (10). A first check valve (21) that functions to permit the flow of drug solution toward the cavity from the drug solution flow path and restrict the flow of drug solution in the opposite direction is provided on a flow path between a drug solution flow path (31) of the cylindrical body and the cavity. A second check valve (22) that functions to permit the flow of drug solution toward the connector from the cavity and restrict the flow of drug solution in the opposite direction is provided on a flow path between the connector and the cavity. Drawing a plunger (45) of the syringe in and out enables a drug solution (72) contained in the drug solution container to be efficiently transferred to the infusion bag.
