Description
Technical Field
[0001] The utility model relates to the technical field of stirring and dispersing equipment, in particular to a stirring and dispersing device for preparing meloxicam injection. Background Art
[0002] Meloxicam (Methylcobalamin) is an active form of vitamin B12, also known as methylcobalamin. It is one of the essential nutrients for the human body and plays an important role in the nervous system, hematopoietic system and other physiological functions. Meloxicam is often used in medicine as a drug to treat problems related to the nervous system. Due to its support for the nervous system, meloxicam is often used to treat various neurological diseases, such as peripheral neuropathy, neuralgia, etc. In addition, meloxicam is also used to treat some anemic diseases because it can promote the production of red blood cells and maintain the normal function of the nervous system. A stirring and dispersing device is required in the preparation process of meloxicam injection.
[0003] The current stirring and dispersing device for preparing meloxicam injection has been gradually found to have the following defects during use:
[0004] (1) The traditional stirring and dispersing device has only one stirring blade inside the stirring and dispersing tank. The stirring and dispersing is performed by one stirring blade, which cannot evenly stir and disperse the raw materials into the liquid medium, thereby affecting the quality of the finished pharmaceutical product. At the same time, a large amount of raw materials will be stained on the inner wall of the stirring and dispersing tank, causing great inconvenience for subsequent cleaning. If it is not cleaned thoroughly, the remaining raw materials will easily form dirt, which will increase the difficulty and time of cleaning and affect the next use.
[0005] (2) There is a high probability that impurities will exist in the solution after stirring and dispersion. If the subsequent operations are carried out directly, the quality of the finished medicine will be seriously affected, which will not only waste a lot of raw material costs but also consume a lot of working time.
