Novel double-hose sealing plug nitrogen-charging device

Abstract

The invention discloses a novel double-hose sealing plug nitrogen-charging device and relates to the field of large infusion drug packages. The double-hose sealing plug nitrogen-charging device is characterized by comprising a plug base (5) and a plug base fixing plate (4), a cavity (51) is vertically formed in the plug base (5), a protruding insertion head (52) is arranged at the lower end of the plug base (5), the upper plane of the plug base (5) is communicated with the lower plane of the insertion head (52) through the cavity (51), a channel (41) through which the upper plane is communicated with the lower plane is formed in the plug base fixing plate (4), the insertion head (52) can be contained in the channel (41), a vacuum-pumping outlet (42) which is communicated with the channel (41) is arranged on one side of the plug base fixing plate (4), and the insertion head (52) is inserted into the channel (41) from the top of the plug base fixing plate (4) and fixes the plug base (5) at the upper end of the plug base fixing plate (4). By the aid of the novel double-hose sealing plug nitrogen-charging device, nitrogen charging and vacuum-pumping replacement can be performed on sealing plugs simultaneously during transportation of the sealing plugs, the working efficiency is improved, the sealing performance is high, and the nitrogen-charging effect is good.

Description

technical field [0001] A novel double-hose sealing plug nitrogen charging device relates to the field of large infusion medicine packaging, in particular to a sealing plug nitrogen charging device. Background technique [0002] Double-hose large infusion soft bag is widely used in developed countries in Europe and the United States. It is a high-end form of soft bag infusion. It is also used by some domestic manufacturers. It is often used to pack drugs that are prone to react with oxygen or as a bag for nutritional infusion. Such as soft bag amino acid and fat emulsion. The sealing plug is used at the interface of the double-hose large infusion soft bag to play a sealing role. When using the double-hose large infusion soft bag, it is necessary to replace the sealing plug with nitrogen to achieve an approximately anaerobic environment to ensure that the drug solution or The nutrient solution does not deteriorate. [0003] At present, there are two commonly used nitrogen fi...

AI Technical Summary

Problems solved by technology

[0003] At present, there are two commonly used nitrogen filling forms for the sealing plug of the double-hose large infusion soft bag. One is to put the nitrogen filling tube outside the sealing plug to blow nitrogen. This method has a poor nitrogen replacement effect; the other is to fill the nitrogen The tube is inserted into the sealing plug to blow nitrogen. This method cannot be vacuumed and due to the limited space, the nitrogen filling tube can only be inserted into a shallow position in the sealing plug. ; and this method is to use a special device to send the nitrogen filling tube to the bottom of the sealing plug to start nitrogen replacement after the sealing plug is transported to the next station, and it takes about 6 seconds to meet the nitrogen filling requirements. Nitrogen filling is completed at one time during the transportation process, and the work efficiency is low
