Calibration solution system for use in an automatic clinical analyzer
A biochemical analyzer adapted to automatically perform calibration and quality control protocols using shuttles adapted to remove calibration and quality control solution vials from a loading tray and to inventory said solution vials on board the biochemical analyzer in a calibration and quality control solution server. In addition, the analyzer is adapted to automatically penetrate the closure covering the opening of the calibration and quality control solution vials, aspirate an amount of solution therefrom and dispense said solution into a test cuvette, thereby eliminating the previous need for operator intervention.
1 . A biochemical analyzer adapted to automatically self-perform calibration and quality control protocols thereon, the analyzer comprising:
an inventory of calibration solution vials on board said analyzer carried in a number of calibration vial carriers, said vials closed with a closure;
an automatic shuttle for moving any one of said vials to an aspiration location;
a probe adapted to automatically penetrate the closure closing said vials;
aspiration means for aspirating a predetermined amount of solution therefrom and to dispense said solution into a test cuvette.
2 . The analyzer of claim 1 wherein calibration and control procedures are automatically conducted on the basis of time lapse between calibrations or on the number of assays performed since an immediately previous calibration or number of assay results outside normal ranges.
3 . The analyzer of claim 1 further adapted to track calibration solution consumption along with time, and date of consumption of all liquids consumed out of each vial on a per vial basis for specifically defined time periods.
4 . The analyzer of claim 1 wherein the vials are inventoried inside controlled environmental servers and may be accessed by aspiration and dispense arms to conduct calibration protocols as required to maintain analyzer in proper operating condition.
5 . The analyzer of claim 2 wherein the shuttle is a bi-directional linear shuttle adapted to position different vials at different locations within said analyzer by moving the vials between a loading tray, at least one server, and at least one carousel.
6 . The analyzer of claim 3 wherein the loading tray includes a motorized rake adapted to automatically position the vials beneath the linear shuttle.
7 . The analyzer of claim 4 having first and second concentric carousels, the first carousel being inwards of the second carousel, the linear shuttle adapted to move vials between the first and second concentric reagent carousels.
8 . The analyzer of claim 5 further comprising a reaction carousel having cuvette ports formed therein to receive a plurality of reaction cuvettes, the aspiration and dispense arms operable to aspirate calibration solution from vials in the carousel and to dispense calibration solution into the reaction cuvettes.
