A double-chamber infusion bag, comprising a sealed soft infusion bag body (1). A first chamber (11) and a second chamber (12) are formed in the soft infusion bag body (1) via a first strip-shaped strippable cold joint structure (13). A second strip-shaped strippable cold joint structure (14) is disposed between the second chamber (12) and an opening tube (2). The breakthrough pressure of the second strip-shaped strippable cold joint structure (14) is greater than or equal to that of the first strip-shaped strippable cold joint structure (13). A composite aluminum film (17) or a transparent or semi-transparent composite material is fixedly connected to the outer side of the second chamber (12). A method for producing a double-chamber infusion bag comprises: manufacturing a double-chamber infusion bag body with an opening tube (2) by welding; filling a first chamber (11) with a liquid drug (15), and then sealing an opening; cutting an opening at the side edge of a second chamber (12) of the sterilized and dried double-chamber infusion bag body, filling with a powdery drug (16), and then sealing an opening; and finally, welding a composite aluminum film (17) or a transparent or semi-transparent composite material on the outer side face of the second chamber (12). It is ensured that a powdery drug (16) and a liquid drug (15) are fully mixed. |
