Powder chamber opening device for powder-liquid dual-chamber infusion bag

The utility model discloses a powder chamber opening device for a powder-liquid dual-chamber infusion bag. The device comprises a rack; the rack is provided with a vacuum absorption mechanism, and a static electricity eliminator for eliminating the static electricity on the infusion bag; and the vacuum absorption mechanism comprises a pair of opposite vacuum chucks, the two vacuum chucks are respectively driven by own driving cylinder to be close to or away from each other, and the vacuum chucks are connected with a vacuum pump by pipelines. For the powder chamber opening device, the two vacuum chucks adsorb two sidewalls of the powder chamber of the infusion bag, and then, the driving cylinders drive the two vacuum chucks to be away from each other, in this way, automatic opening of the powder chamber of the infusion bag is realized.
