Description

Technical Field

[0001] The present invention relates to the technical field of medical testing instruments, and particularly relates to a device for batch dispensing of pharmaceuticals for pharmaceutical experiments. Background Art

[0002] Pharmaceutical experiments are an indispensable part of the pharmaceutical field, which cover multiple aspects such as drug research, development, quality control, and clinical application. Common types of pharmaceutical experiments include: drug synthesis experiments, drug analysis experiments, drug pharmacodynamics experiments, pharmaceutical preparation experiments, drug metabolism and pharmacokinetics experiments;

[0003] When conducting pharmaceutical experiments for preparing pharmaceutical ratios, it is necessary to dispense the large-capacity pharmaceuticals stored in a whole bottle into different medicine bottles for the preparation of pharmaceuticals. When dispensing pharmaceuticals, medical staff have to use syringes or droppers to repeatedly extract the pharmaceuticals in order to equally dispense the pharmaceuticals in the large-capacity bottle into the dispensing containers, which is troublesome to operate;

[0004] Moreover, when equally preparing the liquid medicine, the amount of the liquid medicine is not an integer. Therefore, when preparing the medicine, medical staff can slightly pull the piston of the syringe to extract a small amount of liquid medicine at the end. Although this method is simple, there are still errors, and it is easy to exceed the extracted amount of liquid medicine due to improper operation. Therefore, for the tiny liquid medicine after the integer, medical staff usually use a dropper to extract the liquid medicine;

[0005] In summary, the problems existing in the prior art are as follows:

[0006] 1. In the prior art during the medicine preparation process, medical staff use syringes to repeatedly extract the liquid medicine for equal extraction and distribution of the liquid medicine, which is troublesome to operate and wastes time;

[0007] 2. In the prior art during the medicine preparation process, in order to ensure the accuracy of liquid medicine extraction, a dropper is usually used in the process of liquid medicine extraction, which is troublesome to operate, and it is not easy to control the quantitative medicine, affecting the accuracy of pharmaceutical experiments;
