Abstract
The present invention relates to an immunoassay device and an immunoassay method. According to an aspect of the present invention, an immunoassay device includes a measurement unit provided with a detection unit disposed at one side of a stage accommodating cartridges having a plurality of wells to move in a direction, in which the plurality of cartridges are arranged, and capable of measuring a state within the well disposed at the outermost side, and including a shielding plate that moves to cover an opened upper portion of the well disposed at the outermost side to block introduction of light into the well.
Claims5
An immunoassay device comprising:
- a stage configured to accommodate a plurality of cartridges, each cartridge of the plurality of cartridges having a plurality of wells that are opened upward, wherein the stage is configured to surround a circumference of the well disposed at the outermost side of the cartridges;
- a solution transfer unit comprising a plurality of tips that are configured to move relative to the stage, are disposed to correspond to positions of the each cartridge, and configured to suction a solution stored in the wells or discharge the suctioned solution from the wells;
- and
- a measurement unit disposed at one side of the stage to move in a direction in which the plurality of cartridges are arranged, and comprising a detection unit for measuring an inside state of the well disposed at the outermost side of the each cartridge, and a shielding plate configured to move to cover an opened upper portion of the well disposed at the outermost side of the each cartridge to block introduction of light into the well,
- wherein a hole through which an end of a tip of the plurality of tips is introduced into an upper portion of the well disposed at the outermost side of the cartridges, is provided in the shielding plate,
- the hole of the shielding plate has a size less than that of an upper hole of the well disposed at the outermost side of the cartridges, and
- when the tip of the plurality of tips is introduced into the well disposed at the outermost side of the cartridges, light incident into the well through a second hole of the shielding plate is blocked.
An immunoassay device comprising:
- a stage configured to accommodate a plurality of cartridges, each cartridge of the plurality of cartridges having a plurality of wells that are opened upward, wherein the stage is configured to surround a circumference of the well disposed at the outermost side of the cartridges;
- a solution transfer unit comprising a plurality of tips that are configured to move relative to the stage, are disposed to correspond to positions of the each cartridge, and configured to suction a solution stored in the wells or discharge the suctioned solution from the wells;
- and
- a measurement unit disposed at one side of the stage to move in a direction in which the plurality of cartridges are arranged, and comprising a detection unit for measuring an inside state of the well disposed at the outermost side of the each cartridge, and a shielding plate configured to move to cover an opened upper portion of the well disposed at the outermost side of the each cartridge to block introduction of light into the well,
- wherein the detection unit and a hole formed in the shielding plate are provided in plurality to measure states of the solutions stored in the plurality of wells disposed at the outermost side of the cartridges at the same time.
