Description

Packaging container with light shield layer

Technical Field

Background

The injection is a sterile solution for injection into body, has quick and reliable action, is not affected by pH, enzyme, food, etc., has no first pass effect, can exert whole body or local positioning effect, and is suitable for patients who are not suitable for oral administration. The most common injections are in the form of solutions, and the production process generally includes solution preparation, filling, sterilization and quality inspection. Some medicines need to be given to patients in time in the form of injection in clinic to rapidly exert pharmacological effects, such as severe patients, coma patients or groups with low bioavailability of oral medicines. However, the injection is not suitable for preparing aqueous solution due to its physical and chemical properties, such as poor stability of damp and heat, and is easily degraded in aqueous solution to generate a large amount of related substances, if the injection is injected into human body, serious adverse reaction may be generated, which causes great safety hidden trouble in clinical use of the injection, and therefore, the injection is not suitable for being prepared into liquid dosage forms for long-term storage.

When the injection is required clinically, the method of preparation is often adopted, namely, before the medicine is used clinically by injection, the medicine without water solvent is dissolved in the proper water solvent, diluted to the required concentration of the medicine, and then immediately injected for administration. The preparation process of the injection medicine strictly complies with aseptic operation guidelines, aseptic operation is carried out in a specified aseptic liquid preparation environment, all medical packages and instruments used in liquid preparation links such as glass bottles, ampoules, infusion bottles or infusion bags, syringes and the like need to be subjected to strict sterilization treatment, liquid preparation personnel need to pay attention to disinfection and necessary protection so as to ensure that the injection medicine is aseptic when injected into a body, and the safety and the effectiveness of medication of a patient are guaranteed. The preparation operation of the medicine is complex, certain workload is caused to medical workers, the risk of contamination in the preparation of the injection exists, and the potential safety hazard exists in the safety of injection administration of patients.

The above problems are solved to some extent by an injection packaging container comprising a separate compartment. The aqueous solvent of the medicine and other components with poor physical and chemical compatibility with the medicine are respectively stored in different cavities of the same injection package, the cavities are mutually isolated, the components in the different cavities can be completely separated in the long-term storage or transportation period before clinical use, and the medicine can not be degraded or deteriorated due to the contact with the aqueous solvent or other incompatible components. The adjacent chambers can be communicated under specific conditions, such as applying a certain direction of extrusion external force or tearing the separation surface along the longitudinal separation sealing strip between the chambers. In clinical application, the chambers of the injection packaging container are communicated, the container is squeezed and shaken to dissolve and mix the components of the medicine evenly, and the injection can be carried out for patients after the prepared medicine is observed to meet the preparation requirements of the medicine specification. The injection packaging container with the multiple cavities is used for preparing the medicine before use, medical instruments such as an additional injector or an infusion bag are not needed, the medicine can be conveniently and safely dissolved and diluted, the preparation process is completely carried out in the package, the risk of contamination does not exist, the aseptic safety of the medicine preparation link is guaranteed, and the operation of medical workers is facilitated.

Although such packaging containers have significant advantages for maintaining drug stability and facilitating the dispensing of the drug, their multiple openable compartment design limits the available packaging materials, such as glass, which are gas impermeable, water impermeable and light blocking. Therefore, some drugs, which are particularly sensitive to light, oxygen, carbon dioxide or moisture, even if packaged separately from an aqueous solvent, may be degraded due to moisture and oxidation of the drug caused by the reaction of the gas and/or moisture penetrating the package with the drug during the period from the factory to the clinical use, and especially, light may increase the content of drug-related substances, causing the risk of safety and effectiveness of clinical medication.
