PURPOSE: To provide an infusion solution bag capable of being liquid-tightly partitioned even when a jig is made lightweight and miniaturized and easy to remove by setting the inner diameter of a circle kept in contact with a rod and the chamfer section of a clamp coupled with the rod and having a C-shaped cross section and chamfer sections on the inner face and the thickness of a film to the relationship expressed by specific equations.
CONSTITUTION: The bag section of an infusion solution bag provided with a mouth portion on a bag-like container 3 made of a synthetic resin film is liquid- tightly partitioned into multiple chambers. This jig for the infusion solution bag is provided with a rod 2 having the outer diameter of R2 and a clamp 1 coupled with it and having a C-shaped cross section and two or more projections (chamfer sections) with curved surfaces on the inner face. The following equations are satisfied: 0.95≤(R2+4t)/R1<1.01, and 10°≤θ≤40°C, where R1 is the inner diameter of the circle kept in contact with the chamfer sections, (t) is the thickness of the film, and θ is the opening angle of the opening section of the clamp 1. This jig for the infusion solution bag has no liquid leak and excellent in operability, thus it is useful for the multi-chamber infusion liquid bag.
