Description

Technical Field

[0001] This utility model relates to the field of exosome extraction equipment, specifically an exosome extraction device that allows for convenient volume control. Background Technology

[0002] Exosomes are small membrane vesicles containing complex RNA and proteins. Various cells can secrete exosomes under normal and pathological conditions. They mainly originate from multivesicles formed by the invagination of lysosomal microparticles within the cell. After the outer membrane of the multivesicle fuses with the cell membrane, they are released into the extracellular matrix. All cultured cell types can secrete exosomes, and exosomes are naturally present in body fluids, including blood, saliva, urine, cerebrospinal fluid, and breast milk.

[0003] Exosomes are currently considered to be specifically secreted membrane vesicles that participate in intercellular communication, and research interest in exosomes is growing. Whether it is to study their function or to understand how to use them for the development of minimally invasive diagnostics, current exosome extraction devices are inconvenient to control the extraction volume, which affects the work efficiency of staff. To address this issue, we propose an exosome extraction device that is convenient for volume control. Utility Model Content
