  • Linear flow regulating apparatus for intravenous infusion
    Patent number: 9662442
    Abstract: The present invention relates to a linear flow regulating apparatus for intravenous infusion, and more particularly, to a flow regulating apparatus which is used in an infusion set for intravenous infusion to regulate the flow rate of a solution injected into a body. To eliminate the difficulties caused by the nonlinearity of conventional flow regulating apparatuses, which regulate flow rates by pressing a solution flow tube to adjust the flow passage area, the linear flow regulating apparatus has a control unit to be put in or taken out along the width of a flow channel unit through which the solution flows when the height and length of the flow channel unit are fixed, and is capable of linearly regulating the flow rate by varying the flow passage area of the flow channel unit by adjusting the width of a flow channel unit.
