Patent ID: 10493453

Abstract:
A mechanical actuator system for performing an assay on a disposable diagnostic cartridge having a plurality of fluid-containing blisters includes a body configured to carry the disposable diagnostic cartridge in stationary relation thereon. A lead screw is operably supported by the body and a drive motor is operably connected to the lead screw. A carriage is threadedly coupled to the lead screw, with the carriage having upper and lower wall spaced from one another. A roller is operably carried by the upper wall of the carriage. The roller is spaced from the lower wall for passage of the diagnostic cartridge between the roller and the lower wall. A driven gear is operably coupled to the roller in meshed engagement with the lead screw. Actuation of the drive motor causes the lead screw to rotate, thereby translating the carriage along the lead screw and concurrently causing the driven gear to rotate the roller.
