Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a liquid medicine dispensing device for pharmaceutical experiment analysis. Background Art

[0002] Pharmacy is a science that focuses on aspects such as the research, development, preparation, quality control, clinical application, and formulation of drug policies for drugs. It covers all aspects including the sources, properties, actions, analysis, identification, dispensing, production, storage, and search (including synthesis) of new drugs. Pharmacy is a bridge between medicine and chemistry, aiming to ensure the safety and effectiveness of drugs while promoting rational drug use;

[0003] During the process of pharmacy experiments, it is necessary to conduct experimental analysis on the active ingredients of the liquid medicine. In the current pharmacy experiment process, in order to evenly distribute the active ingredients in the liquid medicine, usually before conducting the sampling of the liquid medicine test, methods such as manual stirring and electric stirring are usually used to assist the full fusion and uniform distribution of the liquid medicine;

[0004] However, the drugs in pharmacy include various types of drugs such as finished drugs and raw materials. Different types of drugs have different dissolution degrees in the liquid medicine. And when tablets and medicinal materials are ground and dissolved in the liquid medicine, they usually carry a certain amount of residue. Therefore, even though the liquid medicine is stirred, it is still impossible to achieve uniform distribution of the active ingredients inside the liquid medicine;

[0005] Moreover, when the liquid medicine is stirred at high speed, under the action of centrifugal force, it is easy to cause precipitates. The liquid medicine with high solubility and a large amount of active ingredients accumulates and sinks to the bottom in the center of the liquid medicine. Therefore, when sampling and testing the liquid medicine at a single position and a single depth, it is impossible to ensure the accuracy of the experimental analysis results of the liquid medicine;

[0006] Therefore, the present invention discloses a liquid medicine dispensing device for pharmaceutical experiment analysis, which comprehensively samples from different depths and different positions and fuses the samples, ensuring that the fused samples are closer to the true active ingredients and proportions in the liquid medicine, and ensuring the accuracy of the pharmaceutical experiment results. Summary of the Invention

The upper ends of the symmetrically arranged screw rods are gear-connected inside the annular groove. The gears on the inner wall of the annular groove and the gears on the outer wall of the annular groove are respectively connected to a screw rod.

[0015] The lower end of the screw rod is threadedly connected to the adjusting plate. By driving the two screw rods to rotate through the operation of the motor, the rotation speed of one screw rod is 1 / 2 of the rotation speed of the other screw rod, driving the two adjusting conduits provided with adjusting plates to rise. The rising speed of the adjusting conduit on one side is 1 / 2 of the rising speed of the other adjusting conduit.
