Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of powder and liquid double chamber bags, specifically an automatic flipping mechanism for powder and liquid double chamber bags. Background Technology
[0002] The powder-liquid dual-chamber bag is a new type of fully enclosed infusion preparation bag. It uses a specific process to package the drug powder and the injectable solvent separately in two independent chambers within the same bag. The two chambers are separated by a perforated weld. Before use, gently squeezing the liquid chamber breaks the weld, allowing the drug powder and solvent to mix and dissolve thoroughly, enabling immediate use. The powder-liquid dual-chamber bag is widely used in the pharmaceutical and related fields, especially in scenarios requiring the mixing of powder and liquid under specific conditions. Traditional methods for conveying and turning powder-liquid dual-chamber bags often present numerous inconveniences and limitations, making it difficult to meet the demands of efficient, continuous, and stable production or usage processes.

The flipping action is not smooth and slow. Furthermore, the connection between the powder-liquid double-chamber bags and the conveying device is not tight enough after flipping, which can easily lead to jamming and stagnation during the conveying process. This seriously affects the overall conveying efficiency and cannot ensure that the powder-liquid double-chamber bags can enter the next process in a timely and continuous manner.
