PROBLEM TO BE SOLVED: To eliminate the gap between a filling nozzle 6 and an infusion bag 2 when inserting the filling nozzle 6 from the opening 2e of the infusion bag 2.SOLUTION: The infusion bag has left and right side portions 2a and 2b, and a bottom portion 2c, where both the side portions are thermally joined to the bottom portion. The upper portion of the infusion bag is thermally adhered, leaving the opening 2e at the center thereof. The infusion bag is held on both sides between a pair of grip members 4A and 4B, and sent to a filling position F. The filling nozzle 6 which can be elevated is located above the position F. The filling nozzle has a two-layer tube structure, and is connected with a medical solution supplying means 12, a vacuum means 20 and a nitrogen gas supplying means 22. First pinching parts 24a and 26a for pinching from outside the filling nozzle inserted into the infusion bag from the opening, and second pinching parts 24b and 26b outside the pinching parts 24a and 26a are provided to a pair of clamp members 24 and 26, respectively. Concaves and convexes 24c, 26c, 24d and 26d which mates with each other are formed at the boundaries between the second pinching parts and the first pinching parts, respectively. |
