Description

Technical Field

[0001] This utility model relates to the field of filling and sealing equipment technology, specifically to a powder-liquid dual-chamber bag making and filling equipment. Background Technology

[0002] In clinical intravenous infusion therapy, 1-3 medications are typically added to the basic infusion solution, and the order in which these medications are prepared is crucial. During preparation, changes in the physicochemical properties of the infusion solution due to puncture and mixing can generate a large number of insoluble microparticles. These microparticles can enter the body and clog capillaries, forming thrombi and granulomas. To address the storage problems of unstable solutions and the cumbersome clinical infusion preparation process, as well as the potential harm to healthcare workers from antibiotics and other medications during preparation, a ready-to-use infusion bag product has been developed, including dual-chamber or multi-chamber bag infusion products. The product is divided into two or more independent chambers by an openable, weakly welded partition, each containing a different injectable solvent or drug powder. Before clinical use, medical staff only need to apply a certain pressure to the liquid chamber, open the weakly welded partition between the different chambers to allow them to communicate, and shake the mixture to ensure that the injectable solvent and drug powder, or multiple injectable drugs, are fully mixed for clinical use. Compared with the current traditional single-chamber infusion bags, it has significant advantages such as shorter drug preparation time, lower contamination rate, quick and convenient operation, and is particularly suitable for the rescue of critically ill patients, thus improving the safety and reliability of infusion use.

[0003] Existing bag-making and filling equipment is not suitable for the production of powder-liquid dual-chamber bags, resulting in low production efficiency. Utility Model Content

[0023] like Figure 1 The illustrated powder-liquid dual-chamber bag making and sealing equipment includes a front carriage and a rear carriage, as well as a bag transfer station 13 for connecting the front carriage and the rear carriage. The front carriage is used for making the powder-liquid dual-chamber bag body, and the rear carriage is used for filling and sealing the liquid chamber of the powder-liquid dual-chamber bag.

[0024] In this embodiment, by setting up a bag transfer station 13 to combine the front and rear vehicles, the transfer process of the powder-liquid dual-chamber bag can be accelerated, making it easier to enter the subsequent liquid filling process. Linking the front and rear vehicles together increases the filling speed of the powder-liquid dual-chamber bag and accelerates the production efficiency of the powder-liquid dual-chamber bag.

[0025] The front section includes the following stations: 2 for film application, 3 for weak welding, 5 for film transfer, 7 for peripheral heat sealing, 8 for interface supply, and 9 for tube heat sealing.
