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.

Claims

1. A diagnostic analyzer comprising:

a darkened optical reading area;

a processing track disposed proximate the darkened optical reading area, the processing track comprising a plurality of slots; and

a reaction vessel moving member configured to move a reaction vessel disposed in one of the plurality of slots out of the slot and into the darkened optical reading area.

2. The diagnostic analyzer of claim 1 wherein the reaction vessel moving member comprises a shaft.

3. The diagnostic analyzer of claim 2 wherein the shaft has a hollow interior which is sized to allow a bottom portion of the reaction vessel to be disposed within the hollow interior, and the shaft further comprises an anti-rotation member to prevent the reaction vessel from rotating relative to the shaft.

4. The diagnostic analyzer of claim 3 wherein the anti-rotation member comprises a pocket.

5. The diagnostic analyzer of claim 2 further comprising a first mating member, the shaft further comprising a second mating member, wherein the first mating member and the second mating member are mated causing the shaft to rotate as it moves between positions.

6. The diagnostic analyzer of claim 5 wherein the first mating member comprises a pin and the second mating member comprises a groove.

7. The diagnostic analyzer of claim 1 wherein the darkened optical reading area comprises a rotating device having a first darkened compartment and a second darkened compartment, the rotating device comprising an optical path along which the first darkened compartment and the second darkened compartment travel.

8. The diagnostic analyzer of claim 7 further comprising a first optical reader and a second optical reader, wherein 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.

9. The diagnostic analyzer of claim 7 wherein the rotating device comprises a rotating turret.

10. The diagnostic analyzer of claim 7 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.

11. The diagnostic analyzer of claim 10 wherein the first reaction vessel holding member comprises a first ledge, and the second reaction vessel holding member comprises a second ledge.

12. The diagnostic analyzer of claim 10 wherein the first reaction vessel holding member comprises a first pivoting member, and the second reaction vessel holding member comprises a second pivoting member.

13. The diagnostic analyzer of claim 10 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.

14. The diagnostic analyzer of claim 1 wherein the darkened optical reading area comprises a darkened compartment, a push-out member disposed within the darkened compartment, the push-out member configured to push the reaction vessel out of the darkened compartment.

15. The diagnostic analyzer of claim 1 further comprising first and second mating members which are mated together, the reaction vessel moving member comprising the second mating member, the first and second mating members configured to cause the reaction vessel moving member to rotate as it moves the reaction vessel out of the slot into the darkened optical reading area.

16. The diagnostic analyzer of claim 15 wherein the first mating member comprises a fixed pin and the second mating member comprises a groove.

17. The diagnostic analyzer of claim 1 wherein the darkened optical reading area comprises a darkened compartment, a pivoting member disposed in the darkened compartment, the pivoting member configured to rotate relative to the darkened compartment to hold the reaction vessel within the darkened compartment.

18. The diagnostic analyzer of claim 1 wherein the reaction vessel moving member has a hollow interior which is sized to hold a portion of the reaction vessel within the hollow interior.

19. The diagnostic analyzer of claim 18 wherein the reaction vessel moving member comprises an anti-rotation member configured to prevent the reaction vessel from rotating relative to the reaction vessel moving member.

20. The diagnostic analyzer of claim 1 further comprising a first optical reader and a second optical reader, wherein the darkened optical reading area comprises a first darkened compartment and a second darkened compartment, the first optical reader configured to read within the first darkened compartment simultaneously as the second optical reader reads within the second darkened compartment.
