Description

Powder-liquid double-chamber soft bag powder filling and sealing machine

technical field

The invention relates to a powder-liquid double-cavity soft bag powder dispensing and sealing machine, which is used for powder-liquid double-cavity soft bag powder dispensing and belongs to pharmaceutical equipment.

Background technique

Infusion soft bag packaging mostly only packs liquid preparations and is a single-chamber container. During clinical infusion, it is necessary to manually mix the therapeutic powder medicine with the infusion solution. Powder medicine is also separately packed in an independent container. During clinical infusion, the liquid medicine in the infusion bag is first extracted with a syringe and injected into the powder medicine container. After the powder is fully dissolved, the solution is returned to the large infusion bag. The operation is troublesome and time-consuming, and it is difficult to ensure the sterility of the dispensing operation environment, which may easily cause drug contamination and dispensing errors.

The powder-liquid double-chamber soft bag solves the above problems very well. The two chambers, the liquid chamber and the powder chamber, can pack liquid preparations and powder preparations at the same time, and the two chambers are separated by virtual welds. In clinical use, the liquid preparation is tapped to squeeze out the virtual weld, and the medicines in the two chambers can be fully mixed and used directly without additional dispensing, which is convenient and quick, ensures aseptic effect, and fundamentally avoids dispensing errors.

The powder-liquid double-chamber soft bag is made of polyolefin co-extruded film or non-PVC film heat-sealed and pressed. Firstly, the double-chamber spaced by virtual welding is implemented, and then the bag is filled with liquid, then sealed with a sealing cover, and finally sealed with powder.
