Problems solved by technology

The existing air flow packing machine is designed to fill the vial with nitrogen after the powder is loaded into the vial and before the rubber stopper is covered. Although it can effectively reduce the oxygen content in the vial, the actual test found that the drug will be produced as the expiry date approaches. Larger color level changes affect the internal quality and drug properties of medicines
At the same time, due to the high flow rate of nitrogen that needs to be filled into the vial, part of the original powder in the bottle will be blown out. In order to ensure the product loading, it is necessary to increase the feeding amount of the original powder, resulting in increased production costs.

Embodiment Construction

[0027] Below in conjunction with embodiment the present invention is described in further detail:

[0028] Such as figure 1 As shown, a nitrogen pre-filling device for an air flow packing machine includes a bottle feeding mechanism, a track block 3 with a guard rail, a transmission mechanism, a turning mechanism and a nitrogen charging mechanism.

[0029] The bottle-feeding mechanism comprises a bottle-feeding track 1 and a bottle-feeding dial 2, and the bottle-feeding track 1 comprises two rows of horizontal grooves side by side, and the bottle-feeding dial 2 is arranged horizontally, and its axis is vertical. The contact point between the bottle feeding track 1 and the bottle feeding dial 2 is at the left end of the bottle feeding dial 2, the contact point between the bottle feeding dial 2 and the track block 3 is at the rear end of the bottle feeding dial 2, and at the end of the bottle feeding dial 2 The difference between the above two places is 90 degrees.

Abstract

The invention discloses a nitrogen filling device for an air flow packing machine, which belongs to a nitrogen charging device for medicine. In the direction of movement, there are bottle feeding mechanism for transferring the vials to the track block, an overturning mechanism for turning the track block over and back, and a nitrogen charging mechanism for filling the overturned vials with nitrogen. The invention fully discharges the air in the bottle, effectively reduces the oxidation speed of the medicine, improves the quality stability of the medicine, reduces the amount of nitrogen gas, and reduces the cost.

Description

technical field [0001] The invention relates to the field of medical equipment, and belongs to a medical nitrogen charging device. Background technique [0002] Due to their special physical and chemical properties, powder injection preparations are prone to oxidative deterioration during production and storage, which reduces the efficacy of the drug. In order to solve this problem, it is common practice to charge nitrogen into the medicinal cillin bottle to reduce the oxygen content in the bottle so as to prolong the storage time. The existing air flow packing machine is designed to fill the vial with nitrogen after the powder is loaded into the vial and before the rubber stopper is covered. Although it can effectively reduce the oxygen content in the vial, the actual test found that the drug will be produced as the expiry date approaches. Larger color level changes will affect the internal quality and drug properties of medicines. At the same time, due to the large nitro...
