Description

Technical Field

[0001] This utility model relates to the field of drug packaging technology, and in particular to a drug packaging structure with a carbon dioxide concentration indicator function. Background Technology

[0002] In the medical industry, many drugs (such as sodium bicarbonate injection) require storage under specific conditions to maintain their effectiveness. In particular, for some carbon dioxide-sensitive drug solutions, it is essential to ensure that the carbon dioxide concentration inside the packaging is maintained within a specific range to prevent drug deterioration or ineffectiveness.

[0003] For products with large outer packaging bags, such as large-volume parenteral solutions, existing technologies exist for detecting carbon dioxide concentration inside the packaging bag. However, for products with small bottle volumes, especially small-volume products such as polypropylene ampoules, the existing carbon dioxide concentration detection structures suitable for large-volume parenteral solutions cannot be used due to the small outer packaging bag volume of these products.

[0004] For pharmaceutical products with small outer packaging, double-layer packaging alone is insufficient to completely prevent carbon dioxide leakage due to pinholes or other defects in the outer packaging. Therefore, a packaging structure capable of real-time monitoring and visually displaying changes in carbon dioxide concentration is needed for pharmaceutical products with small outer packaging. Utility Model Content

[0005] To address the problems existing in the prior art, namely that the packaging structure of small-volume pharmaceutical products cannot monitor and display changes in carbon dioxide concentration in real time, the purpose of this utility model is to provide a pharmaceutical packaging structure with carbon dioxide concentration indication. By optimizing the label structure affixed to the pharmaceutical bottle, the carbon dioxide detection device is combined with the product label, allowing the carbon dioxide detection device to be fixed to the bottle along with the product label during the pharmaceutical product production process. This not only enables real-time monitoring of carbon dioxide concentration inside small-volume pharmaceutical product packaging bags but also simplifies the product production process and achieves rapid automated production.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A drug packaging structure with carbon dioxide concentration indication is provided for packaging a bottle structure containing a drug. The bottle structure includes an outer barrier bag, a label structure, and a carbon dioxide indicator. The bottle structure is located inside the outer barrier bag, which is filled with carbon dioxide. The label structure includes a label body and an adhesive layer. The adhesive layer is disposed on one side of the label body, and the label body is fixed to the bottle structure by the adhesive layer. The carbon dioxide indicator is fixed to the label body.

[0008] The present invention is further configured such that: a receiving groove is provided on the label body, and the carbon dioxide indicator is fixed in the receiving groove.

[0009] The present invention is further configured such that the shape and size of the carbon dioxide indicator are adapted to the receiving tank.

[0010] The present invention is further configured such that the label structure also includes a film, which covers the receiving groove.

[0011] The present invention is further configured such that the film completely covers the side of the label body away from the adhesive layer.

[0012] The present invention is further configured such that a colorimetric card is also provided on the label body.

[0013] The present invention is further configured such that the colorimetric card is positioned close to the carbon dioxide indicator on the label body.

[0014] The present invention is further configured such that: the label structure also includes an anti-stick release film, which can cover the side of the adhesive layer away from the label body.

[0015] In summary, the beneficial effects achieved by this utility model are as follows:

[0016] (1) By using carbon dioxide indicator to monitor the carbon dioxide concentration in the packaging bag of drug products in real time, and embedding the carbon dioxide indicator into the label body, the carbon dioxide indicator can be fixed to the bottle structure along with the label structure during the drug production process, thus solving the problem that it is not easy to place the carbon dioxide indicator in the packaging bag of small-volume drug products. Moreover, this packaging structure is also suitable for the packaging of large-volume drug products, and has a wider range of applications.

[0017] (2) The carbon dioxide indicator is confined within the container by the accommodating groove and the film on the label body, which prevents the carbon dioxide indicator from shifting and also protects it.

[0018] (3) The colorimetric card is also set on the label body and close to the carbon dioxide indicator. It can be fixed to the bottle structure along with the label structure and is convenient for personnel to observe and judge the degree of color change of the carbon dioxide indicator.

[0019] (4) The film completely covers the label body, which not only facilitates processing, but also provides comprehensive protection for carbon dioxide indicators, color charts and label text. Attached Figure Description

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] As attached Figure 1-2 As shown, a drug packaging structure with carbon dioxide concentration indication is used to package a bottle structure 1 containing a drug. The packaging structure includes an outer barrier bag 2, a label structure 3, and a carbon dioxide indicator 4.

[0027] The bottle structure 1 in this invention can be a bottle for large-volume intravenous infusion drugs or a bottle for smaller-volume ampoules. The bottle structure 1 internally encapsulates an injectable drug, such as sodium bicarbonate injection.

[0028] The bottle structure 1 is located inside the outer barrier bag 2. The outer barrier bag 2 is sealed and filled with carbon dioxide gas, thereby providing a suitable storage environment for the medicine inside the bottle structure 1 and preventing the medicine from deteriorating or becoming ineffective.

[0029] Carbon dioxide indicator 4 is usually made of plastic or paper materials and contains acid-base regulators, color-changing agents, UV stabilizers, etc. It is a preparation with carbon dioxide concentration indication function in the prior art, which can display different colors according to different carbon dioxide concentrations.

[0030] The label structure 3 needs to be fixed to the bottle structure 1 during the drug product manufacturing process. It includes the label body 31, the adhesive layer 32, the anti-sticking release film 33, and the coating 34.

[0031] The label body 31 has a certain thickness. In this embodiment, the label body 31 is a cuboid with a length of 3cm to 20cm, a width of 0.5cm to 15cm, and a thickness of 0.08mm to 4mm. In some other embodiments, the label body 31 may also have rounded square, oval, or circular shapes.

[0032] A recessed receiving groove 312 is provided on one side of the label body 31. In this embodiment, the receiving groove 312 is cuboid in shape, with a length of 1cm to 10cm, a width of 0.5cm to 3cm, and a thickness of 0.08mm to 4mm. The receiving groove 312 is used to accommodate and limit the carbon dioxide indicator 4. The shape and size of the carbon dioxide indicator 4 are adapted to the receiving groove 312, so that the carbon dioxide indicator 4 can be firmly fixed in the receiving groove 312.

[0033] The side of the label body 31 that faces away from the bottle structure 1 and has the receiving groove 312 is referred to as the front side of the label body 31. The front side of the label body 31 also has label text 311 and color chart 313.

[0034] Both the label text 311 and the colorimetric card 313 are printed on the surface of the label body 31. The label text 311 is used to record relevant production information of the drug product, and the colorimetric card 313 is used to assist personnel in comparing the color change of the carbon dioxide indicator 4 to determine the concentration of carbon dioxide.

[0035] In this embodiment, the label text 311 and the color chart 313 are located at the top and bottom of the receiving groove 312, respectively, and the color chart 313 is positioned close to the carbon dioxide indicator 4 to facilitate color comparison.

[0036] A film 34 is applied to the front of the label body 31, and the material of the film 34 is polyethylene, polyvinyl chloride, or polypropylene plastic. The film 34 completely covers the front of the label body 31, providing protection against damage, scratches, and contamination to the color chart 313 and label text 311. Furthermore, the film 34 helps to fix the carbon dioxide indicator 4 within the receiving slot 312 and protects the carbon dioxide indicator 4. Specifically, the film 34 prevents the carbon dioxide indicator 4 in the receiving slot 312 from excessive drying during transportation and storage, which could lead to poor color change. The film 34 also does not affect the normal color reaction between the carbon dioxide gas in the outer barrier bag 2 and the carbon dioxide indicator 4.

[0037] An adhesive layer 32 is disposed on the back of the label body 31, allowing the label body 31 to be fixed to the bottle structure 1 via the adhesive layer 32. The main components of the adhesive layer 32 are polyurethane (PUR) adhesive and low-migration adhesive with low migration inhibitors, making it suitable for adhesion to the bottle structure 1.

[0038] The release film 33 can cover the side of the adhesive layer 32 facing away from the label body 31, thereby protecting the adhesive layer 32 when needed. The release film 33 is made of polyester film or polyethylene film, and its thickness is 0.05~0.4mm.

[0039] The implementation principle of the above embodiments is as follows:

[0040] During the drug manufacturing process, the drug is sealed in the bottle structure 1. After the carbon dioxide indicator 4 is embedded in the receiving groove 312 on the front of the label body 31, a film 34 is covered on the front of the label body 31. The label structure 3, with the anti-adhesive release film 33 removed, is affixed to the bottle structure 1, and then the bottle structure 1 is placed in the outer barrier bag 2. Carbon dioxide gas is then filled into the outer barrier bag 2, and the outer barrier bag 2 is sealed. The carbon dioxide gas sealed in the outer barrier bag 2 can pass through the film 34 and react with the carbon dioxide indicator 4 fixed in the receiving groove 312 to produce a color reaction. Medical personnel can compare the current color of the carbon dioxide indicator 4 with the color on the color chart 313 below to determine the effectiveness of the drug in the bottle structure 1.

[0041] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
