A large infusion liquid filling nitrogen filling stopper press machine

Abstract

The invention discloses a large infusion liquid filling nitrogen-filling stoppering machine, which comprises a frame and a bottle-feeding station, a filling station, a nitrogen-filling station after filling, and a corking station arranged on the frame and connected in sequence. The station and the bottle outlet station, the filling station and the nitrogen filling station after filling, the nitrogen filling station after filling and the corking station are all connected by a transition station. Among them, the bottle entry station and the transition station Each position is equipped with a nitrogen protection device for injecting nitrogen into the bottle body and mouth of the glass infusion bottle and forming a nitrogen coverage area at the mouth of the bottle; it can be seen that by adding a nitrogen protection device, the infusion bottle can be placed between each station. It is always in an environment full of nitrogen when traveling between spaces, which can effectively reduce the amount of residual oxygen in the bottle and make it meet the general control requirements. It does not need to seal and repeatedly vacuumize the infusion bottle. The cost is low and the production speed is not affected. It matches the production speed of other equipment on the production line, so it has excellent cost performance.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nitrogen-filled stopper press machine for large infusion solution filling. Background technique [0002] Large infusions are one of the five major types of important preparations in my country's pharmaceuticals. Currently, the infusion preparations sold on the market are mainly plastic bottle infusions and glass bottle infusions, especially nutritional infusions (such as amino acids) and For other therapeutic infusions, glass bottles are basically used for filling. Although this medicinal liquid has certain requirements to the amount of residual oxygen in each infusion bottle, it is not extremely strict (such as about 3%). [0003] In the prior art, the control of the amount of residual oxygen in the infusion bottle is mainly accomplished by vacuuming the nitrogen-filled plugging machine. During production, the vacuuming and nitrogen-filled plugging machine seals the ...

Problems solved by technology

[0003] In the prior art, the control of the amount of residual oxygen in the infusion bottle is mainly accomplished by vacuuming the nitrogen-filled plugging machine. During production, the vacuuming and nitrogen-filled plugging machine seals the mouth of the infusion bottle, and then repeatedly pumps the Vacuum nitrogen filling operation reduces the residual oxygen in the infusion bottle, and then presses the stopper while keeping the airtight state. For the above-mentioned liquids that do not have very strict requirements on the residual oxygen, although it can be accurately controlled and maximized to ensure that each The amount of residual oxygen in the infusion bottle is kept at a minimum, but the vacuum-pumping and nitrogen-filling stoppering machine needs to keep the seal and repeat vacuum-pumping and nitrogen-filling, so its cost is high, and its production speed is slow, which will cause the entire production line to The production speed of the equipment is reduced to match it, reducing the production speed, increasing the production cost, and the cost performance is poor
