DRUG SUPPLY DEVICE

Abstract: a drug supply device includes: a tube body; a first expansion member configured to be expanded to a first outer diameter and a second expansion member configured to be expanded to a second outer diameter that is greater than the first outer diameter, the first expansion member and the second expansion member being positioned on a distal-end side of the tube body; and a masking member that extends between the expansion members and that is connected to outer surfaces of the expansion members at two ends thereof. the tube body includes an outlet that opens between the expansion members and a channel that is in communication with the outlet, the masking member is formed in an arc shape in a lateral cross-section that is orthogonal to the longitudinal axis, and the masking member stretches between the expansion members in a state in which the expansion members are expanded.
