LINEAR FLOW REGULATING APPARATUS FOR INTRAVENOUS INFUSION

摘要

PURPOSE: A linear flow rate controller for fluid injection is provided to linearly control a flow rate proportional to a width of the flow rate moving inside of a flow rate channel part by changing a flow area by controlling a width of the flow rate channel part. CONSTITUTION: A linear flow rate controller for fluid injection is used in a fluid injection set and comprises a flow rate channel part(10) having a rectangular cross-section in which a fluid flows through; a pinion control part(60) that rotates the flow rate channel part by gearing with multiple joint that are formed at an outer circumference surface of the control part; a control part(20) that is operated at one side of the flow rate channel part to ingress or discharge the fluid and changes a flow surface inside the flow rate channel part; and a find control part(30) that is formed at a contact area between the flow rate channel part and the control part and capable of controlling a distance in a width direction of the control part.
