Analyte collecting device, and analyte collecting method and analyte inspection system using same

An analyte collecting device comprising:

• a case including an opening and an internal space;
• and
• a piston including one or more partition walls dividing the internal space into a plurality of internal sections, the piston being inserted into the internal space through the opening of the case to reciprocate in the internal space,
• wherein the case further includes:
• a specimen injection port including an injection hole to allow the internal space to communicate with an outside of the case so that a sample can be injected through the injection hole,
• wherein the specimen injection port further includes a cap configured to seal the injection hole by selectively covering the injection hole, and
• wherein the injection hole is formed in a side surface of the case to extend in a direction perpendicular to an insertion direction of the piston,
• wherein the one or more partition walls include four partition walls,
• wherein the plurality of internal sections include a first section, a second section, a third section, and a fourth section sequentially divided by the four partition walls, the first section to the fourth section being sequentially disposed away from the opening of the case,
• wherein the first section is filled with a solution configured to dissolve a biomaterial contained in the sample and binds at least a portion of an analyte in the biomaterial to a magnetic substance,
• wherein the second section is filled with a solution configured to wash at least a portion of the analyte bonded to the magnetic substance,
• wherein the third section is filled with a solution configured to elute at least a portion of the analyte bonded to the magnetic substance from the magnetic substance, and
• wherein the fourth section is formed adjacent to the third section and in contact with an inner end of the case.
