[0002] The development of the pharmaceutical manufacturing industry has improved the cure rate of diseases and reduced the suffering of patients. For the R&D team in the pharmaceutical manufacturing team, in order to test the new drugs and test their medicinal properties, it is necessary to conduct repeated tests and comparisons, and to qualitatively determine the medicinal properties by extracting the liquid after the test. For mixed liquid medicines, extracting a small amount of liquid medicine can be representative.

[0003] A biomedical sampling device proposed by searching the publication number CN216594315U is supported and fixed by combining the brackets on both sides of the tube sleeve, and the extracted samples are transferred to the collecting bottle for collection through a catheter.
