Abstract

There is provided a sterilisation assembly for a molecular diagnostic assay analyse. The assembly comprising: an enclosure having a passage therethrough, the passage being arranged in use to allow an assay sample set to pass through the enclosure, the enclosure defining a barrier adapted in use to restrict fluid communication across the enclosure to communication through the passage; and a decontaminator located within the passage, the decontaminator is arranged in use to sterilise contamination in the passage.

First claim

The invention claimed is:

1. A sterilisation assembly for a molecular diagnostic assay analyser, the sterilisation assembly comprising:
an enclosure having a passage therethrough, the passage to allow an assay sample set to pass through the enclosure, the enclosure defining a barrier to restrict fluid communication across the enclosure to communication through the passage; and
a decontaminator located within the passage, the decontaminator to sterilise contamination in the passage;
a moveable stage to removably mount at least one sample;
wherein the moveable stage is to move along a path through the passage, the decontaminator being attached to the moveable stage.

2. The sterilisation assembly according to claim 1 , wherein the passage is defined by a tunnel forming part of the enclosure.

3. The sterilisation assembly according to claim 2 , wherein an inwardly facing surface of the tunnel is polyurethane.

4. The sterilisation assembly according to claim 1 , further comprising an elevated platform in the passage, the moveable stage being connected to an electrical cable, the cable passing under the elevated platform.

5. The sterilisation assembly according to claim 4 , wherein the cable has a swivel joint.

6. The sterilisation assembly according to claim 1 , wherein the moveable stage is arranged to move along a rail.

7. The sterilisation assembly according to claim 1 , further comprising a drive mechanism arranged to move the moveable stage.

8. The sterilisation assembly according to claim 7 , wherein the drive mechanism comprises a belt to which the moveable stage is attached.

9. The sterilisation assembly according to claim 1 , wherein the decontaminator is attached to the moveable stage.

10. The sterilisation assembly according to claim 9 , wherein the moveable stage is orientated with at least one side crossing the path, the decontaminator being attached at a side of the moveable stage crossing the path.

11. The sterilisation assembly according to claim 10 , wherein the moveable stage is moveable between a first position and a second position, when the moveable stage is located at the first position, the side of the moveable stage to which the decontaminator is attached is distal to the second position.

12. The sterilisation assembly according to claim 1 , wherein the passage is accessible by one or more openings, each opening having an area of less than or equal to the area of an upper surface of the moveable stage.

13. The sterilisation assembly according to claim 1 , wherein the passage includes at least one turn.

14. The sterilisation assembly according to claim 13 , wherein the turn changes the direction of the passage by an angle greater than an acute angle.

15. The sterilisation assembly according to claim 14 , wherein the turn is U shaped.

16. The sterilisation assembly according to claim 1 , further comprising a pump arranged to move gas within the passage.

17. The sterilisation assembly according to claim 16 , wherein the enclosure includes an outlet connected to the pump.

18. The sterilisation assembly according to claim 17 , wherein the outlet comprises a filter.

19. The sterilisation assembly according to claim 16 , wherein the enclosure includes an inlet connected to the pump.

20. The sterilisation assembly according to claim 19 , wherein the inlet comprises a filter.

21. The sterilisation assembly according to claim 16 , wherein the pump comprises at least one fan.

22. The sterilisation assembly according to claim 1 , wherein the decontaminator is arranged to produce electromagnetic radiation to provide radiation sterilisation.

23. The sterilisation assembly according to claim 22 , wherein the electromagnetic radiation is Ultraviolet C (UVC) radiation.
