Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical mixing devices, and more particularly to pharmaceutical mixing devices for pharmaceutical research. Background Technology
[0002] A drug mixing apparatus for drug research is a specialized device used in the drug development stage to mix two or more drug components (including active pharmaceutical ingredients, excipients, etc.). Its main purpose is to ensure that the drug components are uniformly and thoroughly mixed to prepare drug samples that meet research requirements. For example, in the preparation of compound drug formulations, different active ingredients need to be mixed with appropriate fillers, disintegrants, lubricants, and other excipients, which requires the use of a drug mixing apparatus.
[0003] In existing technologies, traditional manual mixing methods, such as grinding and mixing with a mortar and pestle, are not only inefficient but also struggle to ensure uniform mixing. In the research phase before large-scale drug production, this inhomogeneity can lead to biased experimental results, hindering accurate assessment of drug performance and delaying new drug development. Since drugs are intended for human use, mixing devices used in drug research have extremely high requirements for hygiene and cleanliness. These devices are typically made of easy-to-clean and sterilize materials, such as high-quality stainless steel or special medical-grade plastics. The design minimizes gaps and dead corners to prevent drug residues and microbial growth. After each use, the device requires a rigorous cleaning and sterilization procedure to avoid cross-contamination between different drugs. While industrial production mixing devices also have hygiene requirements, the cleanliness standards are relatively lower in some non-sterile drug production processes.
[0004] Therefore, in order to solve the above problems, this utility model provides a drug mixing device for drug research, which aims to improve the shortcomings of the prior art. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A pharmaceutical mixing device for drug research includes a mixing cylinder. Fixed plates are fixedly installed on both sides of the upper part of the mixing cylinder.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figures 1-6 One embodiment provided by this utility model:
[0036] A pharmaceutical mixing device for drug research includes a mixing cylinder 1. Fixing plates 2 are fixedly installed on both sides of the upper part of the mixing cylinder 1. A sorting mechanism 3 is installed between the two fixing plates 2 for sorting and storing pharmaceuticals. The fixing plates 2 are fixedly connected to the sorting mechanism 3. A mixing and cleaning mechanism 4 is installed inside the mixing cylinder 1 for mixing multiple pharmaceuticals and cleaning the inside of the mixing cylinder 1. A collecting mechanism 5 is installed at the bottom of the mixing cylinder 1 for collecting the mixed pharmaceuticals and the wastewater after cleaning the inside of the mixing cylinder 1.
[0037] The sorting mechanism 3 includes a sorting box 301 fixedly installed between fixed plates 2. Multiple first baffles 302 are installed on the top of the sorting box 301. A damping shaft 303 is installed on one side of each of the multiple first baffles 302. The damping shaft 303 is rotatably connected to the first baffles 302.
[0038] Specifically, the internal space of the sorting box 301 is rationally planned. The damping shaft 303 and the first baffle 302 are connected by a rotating connection. This rotating connection design allows the first baffle 302 to be flexibly adjusted in angle according to actual operational needs, facilitating the dispensing and sorting management of medicines.
[0039] The sorting box 301 has multiple partitions 304 installed inside, and a bottom plate 305 is installed at the bottom of the sorting box 301, with multiple openings on the bottom plate 305.
[0040] Multiple material conveying pipes 306 are installed at the bottom of the base plate 305. Each material conveying pipe 306 corresponds to a set opening. An electric valve 307 is installed at one end of each of the multiple material conveying pipes 306.
[0041] Furthermore, the partition 304 cleverly divides the internal space of the sorting box 301 into several relatively independent small areas, greatly improving the accuracy and convenience of drug sorting and storage. The opening on the bottom plate 305 fits tightly with the subsequent conveying pipe 306, forming a key channel for drugs to enter the mixing cylinder 1 from the sorting box 301. These electric valves 307 precisely regulate the opening and closing degree of each conveying pipe 306 and the flow rate of the drugs.
[0042] The mixing and cleaning mechanism 4 includes a rotating rod 401 installed inside the mixing cylinder 1. The two ends of the rotating rod 401 are connected to the two sides of the mixing cylinder 1 respectively. Multiple fan blades 402 are installed around the outside of the rotating rod 401. A servo motor 403 is installed on one side of the outside of the mixing cylinder 1. The output end of the servo motor 403 is fixedly connected to one end of the rotating rod 401.
[0043] Specifically, when the fan blade 402 rotates at high speed driven by the rotating rod 401, it can generate strong airflow disturbance and stirring effect inside the mixing cylinder 1, which promotes the rapid mixing and dispersion of different drugs, thereby achieving a highly efficient and uniform mixing effect. The servo motor 403 is the power source that drives the rotating rod 401 to rotate.
[0044] A hot air blower 404 is fixedly installed on the other side of the outside of the mixing cylinder 1. Cleaning cylinders 405 are installed on both sides inside the mixing cylinder 1. A jet nozzle 406 is installed at the bottom of the cleaning cylinder 405.
[0045] Furthermore, the cleaning cylinder 405 serves as a container for storing cleaning fluid, containing a specially formulated cleaning fluid for the internal cleaning needs of the mixing cylinder 1. After the internal cleaning of the mixing cylinder 1 is completed, the high-temperature airflow generated by the hot air blower 404 dries the inside of the mixing cylinder 1, removing residual moisture and humidity. Simultaneously, the cleaning fluid in the cleaning cylinder 405 is sprayed out in the form of a high-pressure jet through the jet nozzle 406, performing a comprehensive and deep cleaning of the inner wall of the mixing cylinder 1, the rotating rod 401, and the fan blades 402, ensuring that the internal condition of the mixing cylinder 1 remains clean and hygienic at all times, and avoiding cross-contamination between different batches of medicines.
[0046] The collecting mechanism 5 includes a first discharge pipe 501 fixedly installed on one side of the bottom of the mixing cylinder 1, and a second discharge pipe 502 installed on the other side of the bottom of the mixing cylinder 1. Both the openings of the first discharge pipe 501 and the second discharge pipe 502 are equipped with control valves 503.
[0047] A first collection box 504 is fixedly installed at the lower part of the second discharge pipe 502, and the outlet end of the second discharge pipe 502 is connected to the inside of the first collection box 504. A second collection box 505 is fixedly installed at the lower part of the first discharge pipe 501.
[0048] The outlet end of the first discharge pipe 501 is connected to the interior of the second collection box 505. A filter screen 506 is installed inside the first collection box 504, and a second baffle 507 is installed at the top of the first collection box 504.
[0049] Specifically, the timing and flow rate of the medicine or wastewater can be precisely controlled by valve 503. The wastewater, after cleaning inside the mixing drum 1, flows into the first collection tank 504 through the second discharge pipe 502 for centralized collection and subsequent treatment. The mixed medicine is collected into the second collection tank 505 through the first discharge pipe 501, and the filter screen 506 effectively intercepts solid impurity particles in the wastewater.
[0050] Working principle: When using this utility model, the specific steps include:
[0051] First, the internal space of the sorting box 301 is rationally planned. The damping shaft 303 and the first baffle 302 are connected by a rotating connection. This rotating connection design allows the first baffle 302 to be flexibly adjusted in angle according to actual operational needs, facilitating the dispensing and sorting management of medicines.
[0052] The partition 304 cleverly divides the internal space of the sorting box 301 into several relatively independent small areas, greatly improving the accuracy and convenience of medicine sorting and storage. The opening on the bottom plate 305 fits tightly with the subsequent conveying pipe 306, forming a key channel for medicines to enter the mixing cylinder 1 from the sorting box 301. These electric valves 307 precisely regulate the opening and closing degree of each conveying pipe 306 and the flow rate of the medicines.
[0053] When the fan blade 402 rotates at high speed driven by the rotating rod 401, it can generate strong airflow disturbance and stirring effect inside the mixing cylinder 1, which promotes the rapid mixing and dispersion of different drugs, thereby achieving a highly efficient and uniform mixing effect. The servo motor 403 is the power source that drives the rotating rod 401 to rotate.
[0054] The cleaning cylinder 405 serves as a container for storing cleaning fluid, which is specially formulated for the cleaning needs of the mixing cylinder 1. After the inside of the mixing cylinder 1 is cleaned, the high-temperature airflow generated by the hot air blower 404 dries the inside of the mixing cylinder 1, removing residual moisture and humidity. At the same time, the cleaning fluid in the cleaning cylinder 405 is sprayed out in the form of a high-pressure jet through the jet nozzle 406, which performs a comprehensive and deep cleaning of the inner wall of the mixing cylinder 1, the rotating rod 401, and the fan blades 402, ensuring that the inside of the mixing cylinder 1 is always clean and hygienic, and avoiding cross-contamination between different batches of medicines.
[0055] The timing and flow rate of the medicine or wastewater can be precisely controlled by valve 503. The wastewater, after cleaning inside the mixing drum 1, flows into the first collection tank 504 through the second discharge pipe 502 for centralized collection and subsequent treatment. The mixed medicine is collected into the second collection tank 505 through the first discharge pipe 501, and the filter screen 506 effectively intercepts solid impurity particles in the wastewater.
[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
