Abstract
A positioning system for a sample analysis device is disclosed. The positioning system comprises (1) a carousel comprising a platform and a sample loading tray mounted on the platform, and (2) a stage comprising a positioning system for positioning the carousel under the optical path of an imaging system. The sample loading tray is configured for holding a cartridge comprising one or more lateral flow cells (LFCs).
Claims9
A positioning system for a sample analysis device, comprising:
- a carousel comprising a platform and a sample loading tray mounted on the platform wherein the sample loading tray is configured for holding a cartridge comprising one or more lateral flow cells, wherein the one or more lateral flow cells (LFCs) include a reaction chamber in fluid communication with a waste chamber, the waste chamber includes a liquid-retaining absorbent;
- and
- a stage comprising a positioning system for positioning said carousel, wherein the carousel is rotatable relative to the stage;
- wherein the rotation of the carousel produces centrifugal forces sufficient to drive water droplets from the reaction chamber in the LFCs toward the liquid-retaining absorbent in the waste chamber;
- and
- wherein the carousel further comprises a clamp comprising a top bar, a bottom bar, and at least one supporting rod connecting the top bar and the bottom bar, wherein the platform and the sample loading tray are disposed between the top bar and the bottom bar of the clamp, wherein the clamp is movable relative to the platform and configured to secure the cartridge in the sample loading tray when the clamp is moved to a lock position,
- wherein the bottom side of the carousel comprises a magnet that facilitates movement of the clamp.

A positioning system for a microarray imaging device, comprising:
- a carousel comprising a platform and a sample loading tray mounted on the platform wherein the sample loading tray is configured for holding a cartridge comprising one or more lateral flow cells, wherein the one or more lateral flow cells (LFCs) include a reaction chamber in fluid communication with a waste chamber, the waste chamber includes a liquid-retaining absorbent;
- and
- a stage comprising a positioning system for X, Y, Z axis positioning said carousel, wherein the carousel is rotatable relative to the stage;
- wherein the rotation of the carousel produces centrifugal forces sufficient to drive water droplets from the reaction chamber in the LFCs toward the liquid-retaining absorbent in the waste chamber;
- and
- wherein the carousel further comprises a clamp comprising a top bar, a bottom bar, and at least one supporting rod connecting the top bar and the bottom bar, wherein the platform and the sample loading tray are disposed between the top bar and the bottom bar of the clamp, wherein the clamp is movable relative to the platform and configured to secure the cartridge in the sample loading tray when the clamp is moved to a lock position,
- wherein the bottom side of the carousel comprises a magnet that facilitates movement of the clamp.
