Problems solved by technology

Then when the three-dimensional motion mixer needs to pour out the mixed medicine after the three-dimensional motion mixer is stopped, the medicine with a larger mass has been thrown to the upper layer under the action of centrifugal force during the last mixing, then the mixed medicine poured directly from the three-dimensional motion mixer The drug is prone to stratification. If it directly enters the tablet compression process, it will affect the uniformity of the medicine powder in each tablet and also affect the weight of the tablet.

Abstract

The invention provides a medicament mixing device for medicament production and processing. The medicament mixing device comprises a three-dimensional motion arm fixed on a three-dimensional motion mixer. The cylinder body comprises a conical part, a cylindrical part and a cylinder cover; a supporting piece is fixed to the lower end of the inner side of the cylindrical part. A first spiral stirring paddle is matched in the conical part; the upper end of the first spiral stirring paddle is connected with one supporting piece through a bearing. A second spiral stirring paddle is arranged in the cylindrical part in a matched mode, the lower end of the second spiral stirring paddle is detachably connected with the upper end of the first spiral stirring paddle, and the upper end of the second spiral stirring paddle is connected with the cylinder cover through a bearing. A partition assembly is detachably connected to the barrel cover. A driving assembly is fixed in the cylinder body; the invention provides a medicament mixing device for medicament production and processing, which can avoid the phenomenon that poured medicaments are layered and prevent the layered medicaments from directly entering a tabletting link to influence the uniformity of medicinal powder in each tablet and the weight of the tablets.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparation appliances, in particular to a pharmaceutical mixing device for pharmaceutical production and processing. Background technique [0002] Before any drug can be used for clinical use, it must be made into a form of application suitable for treatment or prevention, called a pharmaceutical dosage form. As the final form of the drug applied to the human body, the dosage form plays an extremely important role in the efficacy of the drug. No matter which dosage form is used, it is necessary to mix multiple raw materials to prepare various dosage forms during preparation. [0003] At present, large pharmaceutical factories generally use special pharmaceutical mixing devices when mixing pharmaceuticals. However, when doing experimental research in schools or scientific research units, only a small amount of medicament is generally needed for testing. At present, a small amount of medica...
