Description
Technical Field
[0001] The present invention relates to the technical field of experimental instruments, and particularly to a quantitative medicine adding and stirring device. Background Art
[0002] In fields such as chemistry and medicine, medicine adding and stirring is a crucial process, which is directly related to the mixing of medicines and the accuracy of experiments. Traditional medicine adding and stirring methods usually require manual operation, which not only consumes a large amount of manpower, but also the control of the medicine adding speed will affect the effect of solution preparation, thereby introducing errors. In addition, traditional medicine adding methods may also cause deliquescence and residue of medicines, which not only affects the accurate addition of medicines, but may also have an adverse impact on experimental results. There are often many problems with the method of manually adding medicines. On the one hand, this method is inefficient and requires a large amount of manpower and time; on the other hand, due to the limited operation speed and accuracy of people, it is difficult to ensure the consistency of the medicine adding speed, resulting in the instability of solution preparation. In addition, the method of manually adding medicines may also cause missed addition or over addition due to the negligence of operators, further affecting the accuracy of experiments. Traditional medicine adding methods are also prone to cause deliquescence and residue of medicines. Some medicines are sensitive to humidity and temperature and are prone to absorb moisture and deliquesce when exposed to air for a long time, while it is difficult to avoid the long-term exposure of medicines in traditional medicine adding methods. In addition, some medicines may adhere to the inner wall of the container during the adding process and are difficult to clean thoroughly, resulting in the residue of medicines. These problems not only affect the accurate addition of medicines, but may also have an adverse impact on experimental results. Summary of the Invention
