Abstract

Example apparatus and methods related to automated diagnostic analyzers having rear accessible track systems. An example apparatus disclosed herein includes an analyzer to perform a diagnostic test, the analyzer having a first side and a second side opposite the first side. The example apparatus includes a loading bay disposed on the first side of the analyzer to receive a first carrier and a pipetting mechanism coupled to the analyzer adjacent the second side. The example apparatus also includes a first carrier shuttle to transport the first carrier from a first location adjacent the loading bay to a second location adjacent the pipetting mechanism and a track disposed adjacent the second side of the analyzer to transfer a second carrier to a third location adjacent the pipetting mechanism.

Claims

1. An apparatus comprising:

an analyzer to perform a diagnostic test, the analyzer having a first side and a second side opposite the first side;

a loading bay disposed on the first side of the analyzer to receive a first carrier;

a pipetting mechanism coupled to the analyzer adjacent the second side;

means for transporting the first carrier from a first location adjacent the loading bay to a second location adjacent the pipetting mechanism; and

means for transporting a second carrier to a third location adjacent and accessible by the pipetting mechanism, the means for transporting the second carrier to the third location located outside of the analyzer.

2. The apparatus of claim 1 further including means for transporting the first carrier from the loading bay to the first location.

3. The apparatus of claim 2, wherein the means for transporting the first carrier from the loading bay to the first location includes means for reading a label on the first carrier.

4. The apparatus of claim 1 further including means for transporting a third carrier from the first location adjacent the loading bay to the second location adjacent the pipetting mechanism.

17. The apparatus of claim 1, wherein the loading bay includes a plurality of slots arranged in a horizontal array along the first side of the analyzer.

18. The apparatus of claim 1, wherein the analyzer includes a first carousel to support a plurality of reagent containers and a second carousel to support a plurality of reaction vessels.

19. The apparatus of claim 1, further including a computer processor including software programmed to:

control the pipetting mechanism to aspirate a first liquid from the first carrier at the second location and dispense the first liquid into a first reaction vessel on the analyzer; and

control the pipetting mechanism to aspirate a second liquid from the second carrier at the third location and dispense the second liquid into a second reaction vessel on the analyzer.

5. A diagnostic analyzer comprising:

a loading bay disposed on a first side of the analyzer, the loading bay to receive a first carrier;

a carrier shuttle to transport the first carrier from a first location adjacent the loading bay to a second location adjacent a second side of the analyzer opposite the first side of the analyzer; and

a pipetting mechanism adjacent the second side, the pipetting mechanism movable along a path between (1) a first point to access the first carrier at the second location and (2) a second point in which the pipetting mechanism extends beyond the second side of the analyzer to access a second carrier adjacent the second side.

6. The analyzer of claim 5 further including a first carousel having a reaction vessel, wherein the pipetting mechanism is further movable along the path to (3) a third point to access the reaction vessel.

7. The analyzer of claim 6 further including a second carousel, wherein the carrier shuttle is disposed over a portion of the second carousel.

8. The analyzer of claim 7, wherein the pipetting mechanism is rotatable about an axis disposed outside of the first carousel and the second carousel.

9. The analyzer of claim 6, wherein the carrier shuttle is a first carrier shuttle, further including a second carrier shuttle to transport a third carrier from the first location adjacent the location bay to the second location adjacent the pipetting mechanism.

10. The analyzer of claim 9, wherein the pipetting mechanism is further movable along the path to (4) a fourth point to access the third carrier at the second location.

11. The analyzer of claim 9, wherein the first carrier shuttle and the second carrier shuttle are adjacent and parallel to each other.

12. The analyzer of claim 9, wherein the first carrier shuttle and second carrier shuttle are independently movable.

13. The analyzer of claim 7, wherein the second carousel includes a reagent container.

14. The analyzer of claim 5, further including a positioner moveable on a track along the loading bay on the first side of the analyzer, the positioner to transport the first carrier from a slot in the loading bay to the carrier shuttle.

15. The analyzer of claim 14, wherein the positioner is to move in a direction substantially perpendicular to the carrier shuttle.

16. The analyzer of claim 5, wherein at least one of the first carrier or the second carrier includes at least one sample tube.

20. The analyzer of claim 5, further including a computer processor including software programmed to:

control the pipetting mechanism to aspirate a first liquid from the first carrier at the first point and dispense the first liquid into a first reaction vessel; and

control the pipetting mechanism to aspirate a second liquid from the second carrier at the second point and dispense the second liquid into a second reaction vessel.
