Abstract

Embodiments according to one aspect of the present disclosure relate to a liquid medicine flow rate regulating device. The liquid medicine flow rate regulating device has a liquid medicine flow path for guiding the flow of liquid medicine, wherein the liquid medicine flow path includes an inlet flow path through which the liquid medicine flows in, a plurality of branch flow paths which branch out from the inflow flow path, and an outlet flow path through which the liquid medicine flows out after converging from the plurality of branch flow paths. The liquid medicine flow rate regulating device according to a representative embodiment includes: a plurality of conveyance pipes which respectively correspond to the plurality of branch flow paths, and which each form a capillary flow path that constitutes at least a portion of a corresponding path among the plurality of branch flow paths; and a valve member configured to selectively open or close the plurality of branch flow paths to regulate the flow rate of the liquid medicine that flows out through the outlet flow path.
