ABSTRACT:
The object of this invention is to provide a device for regulating the flow rate of an intravenous medical solution during an injection using an intravenous drip unit. The device has a housing (10) mounted to a hose (300) to allow the flow of the solution from a solution container (200) into the vein, and a control member (20) rotatably assembled with the housing to regulate the flow rate of the solution. The housing has first and second seats (11, 12) communicating with inlet and outlet ports, and the control member has first and second bosses (21, 22) seated in the first and second seats. An arc-shaped solution path (23), a radial channel (24) and an annular groove (25) are formed on the control member to regulate the flow rate of the solution in accordance with an adjusted angle of the control member relative to the fixed housing.
