Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical experimental equipment, in particular to an adjustable quantitative sampling device for pharmaceutical experiments. Background Art

[0002] In the pharmaceutical experiment process, various solution-type drugs need to be extracted and mixed to form new drugs. Since the development of new drugs requires precise ratios of various raw materials, a special sampling device is required to strictly control the drug quantity when extracting solution-type drugs.

[0003] The existing patent CN213644182U discloses a quantitative sampling device for pharmaceutical experiments. Although the patent can solve the problem that a pharmaceutical experiment sampling device is disclosed in the patent specification with the publication number CN212674527U, which accurately extracts the drug solution by means of a sampling pipette and a sampling bottle, this sampling method requires squeezing the rubber ball on the sampling pipette to discharge the solution in the form of air compression when extracting the drug solution into a designated container. When squeezing the rubber ball, the sampling pipette is prone to shaking, causing the drug solution to spill outside the container. However, when sampling, if the sampled solution does not reach the required scale value during the process of deformation and restoration of the squeezed rubber, the patent needs to re-sample until the sampled solution exceeds or reaches the required scale value, which will waste time. Therefore, an adjustable quantitative sampling device for pharmaceutical experiments is invented. Summary of the invention
