Abstract

A diagnostic analyzer includes a rotating device, a first optical reader, and a second optical reader. The rotating device includes a first darkened compartment, a second darkened compartment, and an optical path along which the first darkened compartment and the second darkened compartment travel. The first optical reader is operable to read the first darkened compartment and the second optical reader is operable to read the second darkened compartment.

First claim

The invention claimed is:

1. A diagnostic analyzer comprising:
a rotating device having a first darkened compartment, a second darkened compartment, and an optical path along which the first darkened compartment and the second darkened compartment travel;
a first optical reader; and
a second optical reader;
wherein (1) the first optical reader is operable to be aligned with the first darkened compartment when the second optical reader is aligned with the second darkened compartment, or (2) the first optical reader is operable to only take readings within the first darkened compartment and the second optical reader is operable to only take readings within the second darkened compartment.

2. The diagnostic analyzer of claim 1 wherein the rotating device comprises a rotating turret.

3. The diagnostic analyzer of claim 1 wherein the first darkened compartment comprises a first reaction vessel holding member for holding a first reaction vessel, and the second darkened compartment comprises a second reaction vessel holding member for holding a second reaction vessel.

4. The diagnostic analyzer of claim 3 wherein the first reaction vessel holding member comprises a first ledge, and the second reaction vessel holding member comprises a second ledge.

5. The diagnostic analyzer of claim 3 wherein the first reaction vessel holding member comprises a first pivoting member, and the second reaction vessel holding member comprises a second pivoting member.

6. The diagnostic analyzer of claim 3 further comprising a first push-out member disposed in the first darkened compartment to push the first reaction vessel away from the first reaction vessel holding member and out of the first darkened compartment, and a second push-out member disposed in the second darkened compartment to push the second reaction vessel away from the second reaction vessel holding member and out of the second darkened compartment.

7. The diagnostic analyzer of claim 1 further comprising a processing track disposed below the rotating device.

8. The diagnostic analyzer of claim 7 further comprising at least one reaction vessel moving member configured to move reaction vessels carried by the processing track out of the processing track and into the first and second darkened compartments.

9. The diagnostic analyzer of claim 8 wherein the at least one reaction vessel moving member comprises at least one shaft.

10. The diagnostic analyzer of claim 9 wherein the at least one shaft has a hollow interior which is sized to allow a bottom portion of a reaction vessel to be disposed within the hollow interior, and the at least one shaft further comprises an anti-rotation member to prevent the reaction vessel from rotating relative to the shaft.

11. The diagnostic analyzer of claim 10 wherein the anti-rotation member comprises a pocket.

12. The diagnostic analyzer of claim 9 further comprising a first mating member, the at least one shaft further comprising a second mating member, wherein the first mating member and the second mating member are mated causing the at least one shaft to rotate as it moves between positions.

13. The diagnostic analyzer of claim 12 wherein the first mating member comprises a pin and the second mating member comprises a groove.

14. The diagnostic analyzer of claim 1 wherein (1) the first optical reader is operable to be aligned with the first darkened compartment when the second optical reader is aligned with the second darkened compartment.

15. The diagnostic analyzer of claim 1 wherein (2) the first optical reader is operable to only take readings within the first darkened compartment and the second optical reader is operable to only take readings within the second darkened compartment.
