Abstract
This sample processing device comprises: an analysis chip having a flow path on a lower surface side; a drive unit having a plurality of recesses on an upper surface side; an elastic film positioned between the analysis chip and the drive unit; and an air pressure control unit that switches whether the elastic film is adhered to the analysis chip side or adhered to the drive unit side. The analysis chip includes a quantitative flow path for quantifying liquid, and at least four branch flow paths branched from the quantitative flow path. The drive unit includes recesses below each of the ends of the four branch flow paths not on the quantitative flow path side, and each of the recesses communicates with the air pressure control unit.
Claims11
A sample processing device comprising:
- an analysis chip including a flow path on a lower surface side;
- a drive portion including a plurality of recesses on an upper surface side;
- an elastic membrane positioned between the analysis chip and the drive portion;
- and
- an air pressure control portion configured to switch whether the elastic membrane is closely attached to an analysis chip side or closely attached to a drive portion side, wherein
- the analysis chip includes a metering flow path for metering a liquid and at least four branch flow paths branched from the metering flow path,
- the drive portion includes a recess below each of an end of the four branch flow paths not on a metering flow path side, and
- each recess is in communication with the air pressure control portion.
