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 method of taking readings of samples using a diagnostic analyzer comprising:
rotating a rotating device to move first and second darkened compartments of the rotating device along an optical path; and
(1) aligning a first optical reader with the first darkened compartment when a second optical reader is aligned with the second darkened compartment, or (2) only taking readings within the first darkened compartment with the first optical reader and only taking readings within the second darkened compartment with the second optical reader.

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

3. The method of claim 1 further comprising a first reaction vessel holding member of the first darkened compartment holding a first reaction vessel containing a first sample, and a second reaction vessel holding member of the second darkened compartment holding a second reaction vessel containing a second sample.

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

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

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

7. The method of claim 1 further comprising at least one reaction vessel moving member moving reaction vessels carried by a processing track out of the processing track and into the first and second darkened compartments.

8. The method of claim 7 wherein the at least one reaction vessel moving member moving the reaction vessels comprises at least one shaft moving the reaction vessels.

9. The method of claim 8 wherein the at least one shaft moving the reaction vessels further comprises disposing bottom portions of the reaction vessels within a hollow interior of the at least one shaft, and an anti-rotation member of the at least one shaft preventing the reaction vessels from rotating relative to the at least one shaft.

10. The method of claim 9 wherein the anti-rotation member preventing the reaction vessels from rotating relative to the at least one shaft comprises a pocket of the at least one shaft preventing the reaction vessels from rotating relative to the at least one shaft.

11. The method of claim 8 wherein the at least one shaft moving the reaction vessels comprises a first mating member of the diagnostic analyzer mating with a second mating member of the shaft causing the shaft to rotate as it moves between positions.

12. The method of claim 11 wherein the first mating member mating with the second mating member comprises a pin and a groove mating.

13. The method of claim 1 comprising (1) aligning the first optical reader with the first darkened compartment when the second optical reader is aligned with the second darkened compartment.

14. The method of claim 1 comprising (2) only taking readings within the first darkened compartment with the first optical reader and only taking readings within the second darkened compartment with the second optical reader.
