Problems solved by technology

When using ampoules or vials to package medicines, nitrogen-filled packaging is mostly used. However, due to the limitation of the gas-filling process, the content of nitrogen and oxygen in the finished product packaging of ampoules or vials will be different from the expected ones. Influenced by airtightness, the above-mentioned gas content will change with the prolongation of storage time
In addition, the content control of nitrogen and oxygen in the finished product packaging will be affected by the volume of the packaging bottle. Those skilled in the art can understand that for large-packed vials or infusion bottles, such as 10-200ml, the control of residual oxygen It is relatively easy, and usually can be controlled below 2% or even 1%. For ampoules or vials with a capacity of 1-5ml, due to limited operation, it is better to reach below 5%, or about 3%. Therefore, in practice In industrial production, the nitrogen filling process and residual oxygen control of small-capacity packaging are much more difficult than large-capacity packaging, and the two are incomparable

Embodiment 1

[0025] Instrument and raw material used in embodiment:

[0026] Potting and sealing machine: AKGF12 / 8X2 type;

[0027] Residual oxygen meter: Model: Oxybaby6.0 / O 2

[0028] Ampoule: 2ml (filling with 2ml liquid medicine) or 5ml (filling with 4ml liquid medicine)

[0029] Liquid nitrogen tank: 210L / tank, nitrogen purity 99.999%

[0030] The on-line filling and nitrogen filling process of bottle washing, sterilizing and drying, bottle delivery, pre-nitrogen filling, quantitative filling, post-nitrogen filling, preheating and wire drawing is adopted to produce 2ml and 5ml ampoules of vitamin C injection.

[0031] AKGF12 / 8X2 type potting and stoppering machine originally had 3 sets of needles, each with 8 needles, one set is the front nitrogen filling needle, i.e. the flat type; .

[0032] In the experiment of comparing the impact of the post-nitrogen filling needle on the residual oxygen content and defective products, the present invention also replaces the post-nitrogen fi...

Abstract

The invention belongs to the field of pharmaceutical packaging, and discloses a method for controlling the residual oxygen at the top of an ampoule or a vial in a pharmaceutical preparation, and a production method for filling a finished product in which the pharmaceutical preparation is filled and sealed in the ampoule or vial. The method adopts high filling speed and low post-filling nitrogen amount, and effectively controls the residual oxygen at the top of the ampoule or vial and the occurrence rate of defective products.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical packaging, and in particular relates to a process for reducing residual oxygen in packaging when filling pharmaceuticals. Background technique [0002] Most pharmaceutical products are sensitive to oxygen and are easily oxidized and deteriorated, causing discoloration and odor, etc., which not only affect the efficacy of the product, but also produce toxic and harmful substances that may even endanger life. Drugs containing hydroxides, calcium salts and other ingredients are easy to absorb Carbon dioxide forms carbonates. In order to reduce the amount of oxygen and carbon dioxide that the medicines are exposed to, the oxygen and carbon dioxide sensitive medicines are usually packaged in packaging forms such as vacuuming and filling with inert gas (usually nitrogen). Therefore, controlling the amount of residual oxygen in the packaging during the production process is one of the important c...
