Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medicament split charging, particularly to a medicine dry-wet separation storage atomization device. BACKGROUND

[0002] The characteristics of unstable drugs mainly include chemical instability, physical instability and biological instability.

[0003] Chemical instability involves the degradation of drugs due to hydrolysis, oxidation and other chemical reactions, resulting in a decrease in drug content or potency, changes in color, etc. These chemical reactions may be accelerated by the chemical properties of the drug itself, storage conditions, and external environmental factors such as temperature, humidity, light, etc.

[0004] Physical instability refers to changes in the physical properties of the preparation, such as coarsening of drug particles in suspensions, precipitation and caking, separation and rupture of emulsions, turbidity and precipitation of solutions, etc. These changes may affect the uniformity and bioavailability of the drug.

[0005] Biological instability involves the spoilage and deterioration of preparations due to microbial contamination. This may be due to ineffective control of microbial growth and reproduction during the production and storage of the preparation.

[0006] In particular, as a medicament for aerosol therapy, it generally has high volatility and naturally belongs to the category of chemically unstable drugs. Some drugs may also have biological instability due to their special ingredients, making them prone to mold and other issues. To prevent oxidation and decomposition of the drug, a series of measures can be taken, such as removing oxygen, adding antioxidants, adjusting pH, etc.

[0007] In addition, the more common method is to prepare the drug as a solid and a liquid, or two different components of a liquid, and then store them separately. When used, the two medicaments are taken and mixed in a specific ratio to dissolve and mix into the final unstable medicament. This mixed medicament needs to be used immediately, otherwise it is difficult to store due to its unstable final properties. Moreover, such medicaments should not be in contact with air for a long time. This method of separating and storing the drug is commonly used in drug storage.

[0008] Although this separated medicament is easy to store, it is difficult to mix the two different medicaments in the right proportion, especially when mixing the medicaments. The mixed medicament is difficult to stir and dissolve uniformly, and the undissolved solid medicament can cause the medicament ratio to be out of balance. Moreover, during the taking and storing of the medicament, especially when a small amount of medicament is taken from a large storage bottle for mixing, air can be mixed into the storage bottle, causing the medicament to oxidize or become damp, which can adversely affect the effectiveness of the medicament.
