LIQUID CONVEYING PUMP

摘要

[Object] To provide an infusion pump having a high safety capable of entirely preventing free flow during fitting and unfitting of an infusion tube. [Solving Means] An infusion pump is provided with a slide clamp mechanism having a clamp member for closing or opening an infusion tube 40 and a valve mechanism for pressing the infusion tube 40 to stop flow of a solution in the infusion tube and has a structure where an interlocking mechanism for interlocking the slide clamp mechanism with the valve mechanism only by manipulation of a handle 23 is disposed. During a series of manipulations of the handle 23, the infusion tube 40 is always closed by one or both of the slide clamp 30 and valves 14A and 14B, so that free flow of a solution in the infusion tube 40 can be entirely prevented.
