Title:
SPECIMEN-PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/146631
Kind Code:
A1
Abstract:
Provided is a specimen-processing device configured so that a flow operation can be performed by deforming an elastic membrane. The present invention has an analysis chip 10 that is a processing unit having a first flow path through which a liquid flows on a lower-surface side, a drive unit 40 that controls air, a membrane 20 that is an elastic membrane disposed between the processing unit and the drive unit, and an air pressure control unit 60 that switches the elastic membrane between adhering to the processing-unit side and adhering to the drive-unit side. The processing unit has formed therein a circulation groove 901 that is a second flow path through which air flows, the circulation groove being formed on the opposite side from the side where the drive unit is disposed, and an adhesion film 21 that is a hermetic sealing film, the adhesion film being provided above the second flow path of the processing unit. The processing unit has a plurality of wells 11-16 that are containers for storing the air and the liquid, each of the wells being connected to the second flow path. The air in the containers flows through the second flow path. This specimen-processing device makes it possible to enable a flow operation in a hermetically sealed processing unit.
