Description

Technical Field

[0001] The utility model relates to the field of drug mixing, in particular to a mixing device for detecting nucleic acid drug components. Background Art

[0002] Nucleic acid drugs, also known as nucleotide drugs, include oligoribonucleotides (RNA) or oligodeoxyribonucleotides (DNA) with different functions, which mainly act at the genetic level. These drugs can be made from nucleic acids (including nucleotides and deoxynucleotides) extracted from animal or microbial cells, or prepared through artificial synthesis. They are substances with nucleic acid structure and pharmacological effects.

[0003] In the process of nucleic acid drug testing, sample mixing is a key step. In the existing technology, most mixing is usually done by clamping the test tube through a clamping assembly. After fixing it, the eccentric wheel is driven by a motor to rotate, causing it to swing up and down under the action of a spring to mix.

The existing clamping components are usually fixed by bolts, and they need to be removed and replaced one by one when replacing reagents. However, the disassembly and assembly process is cumbersome and difficult to operate smoothly, affecting experimental efficiency. Utility Model Content
