Mechanical actuator system and method of actuation of a diagnostic device therewith
First Claim
1. A mechanical actuator system for performing an assay on a disposable diagnostic cartridge having a plurality of fluid-containing blisters, comprising:
- a body having a base and a pair of support flanges extending upwardly from said base in spaced relation from one another, said body being configured to carry the disposable diagnostic cartridge in stationary relation thereon;
at least one lead screw extending between opposite ends, one of said opposite ends being operably supported by one of said flanges and the other of said opposite ends being operably supported by the other of said flanges;
a drive motor operably connected to one of said opposite ends of said at least one lead screw;
at least one carriage threadedly coupled to a respective one of said at least one lead screw;
at least one roller operably carried by said at least one carriage for rotation to compress at least one of the fluid-containing blisters on the diagnostic cartridge; and
a driven gear operably coupled to said at least one roller for conjoint rotation therewith, said driven gear being configured in meshed engagement with one of said at least one lead screw,wherein actuation of said drive motor causes said at least one lead screw to rotate, thereby causing said at least one carriage to translate along said at least one lead screw and concurrently causing said driven gear and said at least one roller to rotate.

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.
