Device for controlling flow rate of infusion solution

Abstract

The present disclosure provides an infusion flow regulator, including: a main body (10) having an inlet through which fluid is introduced and an outlet through which the fluid is discharged; and a rotary dial (30) rotatably coupled to the main body, with a sealing member (20) interposed therebetween, so as to regulate the flow rate of the fluid, in which the rotary dial includes a regulating flow path (31) having a shape of a recessed groove in cross section with a first width and a first height, and the regulating flow path (31) includes a first region in which the width is constant and the height is decreased, and a second region in which both the width and height are decreased. By the configuration described above, the device for regulating infusion solution according to the present disclosure has an effect of accurately regulating the flow rate even in a region where the flow rate of the infusion solution is a very small.
