| description | The utility model discloses a spliced-formed powder-liquid dual-chamber infusion bag which comprises a powder bag and a liquid bag. The powder bag is separated from the liquid bag through at least one weak welding rod. The wall of the infusion bag is made of a multi-layer co-extruded film material provided with an inner layer and an outer layer at least, the inner layer of the liquid bag is made of polypropylene/modified polypropylene, the inner layer of the powder bag is made of polyethylene/modified polyethylene, and splicing strips are arranged at the joints between the wall of the liquid bag and the wall of the powder bag. The double-barreled question that polyethylene or polypropylene is separately used as inner layers of chambers is solved, a polyethylene/modified polyethylene film material serves as the inner layer of the powder bag, the film material and medicine powder have good compatibility, and a polypropylene/modified polypropylene film material serves as the inner layer of the liquid bag needing terminal sterilization and can meet the requirement for terminal sterilization; the infusion bag is extruded when used, so the weak welding rods can be broken, the powder bag is communicated with the liquid bag, and sterile mixing of powder and liquid is achieved. The utility model further discloses a method for manufacturing the spliced-formed powder-liquid dual-chamber infusion bag. |
