Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical excipient mixing technology, specifically a pharmaceutical excipient mixing device. Background Technology

[0002] Drug adjuvants can enhance the efficacy and reduce the toxicity of anticancer drugs. They can also improve patient tolerance. Drug adjuvants optimize treatment effects through various mechanisms, such as improving drug solubility and stability, making them easier for cancer cells to absorb. Some drug adjuvants can also enhance targeting, making their effects more accurate and reducing damage to normal cells. By scientifically mixing drug adjuvants with anticancer drugs, individualized treatment plans can be developed to ensure the effectiveness and safety of treatment.

[0003] For example, a mixing device for chemical auxiliaries described in patent document CN221267819U, through the design of a feeding mechanism, namely an electronic control component, two feeding pipes and two sliding components, can drive the two feeding pipes to move away from each other, so that both feeding pipes slide horizontally from the center of the top cover to the edge of the top cover. This allows the raw materials used to produce chemical auxiliaries to be evenly sprinkled inside the tank, preventing concentrated accumulation. During mixing, the raw materials are more evenly dispersed inside the tank, rather than accumulating near the center or edge of the tank, thus improving the mixing effect and thereby increasing the production rate of chemical auxiliaries. However, when mixing highly viscous auxiliaries, this mixing device for chemical auxiliaries is prone to the auxiliaries adhering to the inner wall of the tank, reducing the mixing quality.

[0004] Based on this, a pharmaceutical excipient mixing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a pharmaceutical excipient mixing device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The upper end of the mixing cylinder is provided with several input seats for connecting to a pharmaceutical excipient input device, and the lower end of the mixing cylinder is provided with several output seats for outputting the mixed pharmaceutical excipient. A rotary motor is provided at the upper end of the mixing cylinder. The fixed end of the rotary motor is fixedly connected to the mixing cylinder, and the output end of the rotary motor is fixedly connected to a stirring rod inside the mixing cylinder. A cleaning mechanism for cleaning the surface of the stirring rod is slidably connected to the stirring rod. The mixing cylinder is provided with a linkage component that scrapes off the pharmaceutical excipient from the inner wall of the mixing cylinder during the stirring process of the stirring rod.
