Abstract

There is provided a tube connector for connecting between a fluid sampling tube and a fluid analyzer, the tube connector includes an end face adapted to identify the tube connector, said end face comprising a reflecting surface having one or more reflective regions adapted to reflect light at a predetermined range of wavelengths.

Claims

1. A tube connector, comprising:

a circular annular end face, at least a portion of the circular annular end face comprising at least two spectrally distinct reflective regions, said at least two spectrally distinct reflective regions configures to reflect light at different wavelengths and arranged such that a tube connection system can identify recurring changes of reflectivity during the revolving of said tube connector relative to said tube connection system.

2. The tube connector of claim 1, wherein said circular annular end face is configured to encode data indicative of a type of said tube connector.

3. The tube connector of claim 1, wherein said circular annular end face is configured to encode data indicative of a preferred mode of operation of said tube connector.

4. The tube connector of claim 1, wherein said tube connection system comprises one or more light sources and one or more optical detectors.

5. The tube connector of claim 4, wherein said one or more optical detectors comprises a red, green, and blue (RGB) detector.

6. The tube connector of claim 1, wherein said at least two spectrally distinct reflective regions comprise at least one geometrical shape.

7. The tube connector of claim 1, wherein the at least two spectrally distinct reflective regions exhibit at least one concave region and at least one convex region.

8. The tube connector of claim 1, wherein the at least two spectrally distinct reflective regions cover a substantial portion of said tube connector.

9. A method, comprising:

forming a tube connector having a circular annular end face; and

applying at least two spectrally distinct reflective regions to at least a portion of the circular annular end face, said at least two spectrally distinct reflective regions configured to reflect light at different wavelengths and arranged such that a tube connection system can identify recurring changes of reflectivity during the revolving of said tube connector relative to said tube connection system.

10. The method of claim 9, wherein said circular annular end face is configured to encode data indicative of a type of said tube connector.

11. The method of claim 9, wherein said circular annular end face is configured to encode data indicative of a preferred mode of operation of said tube connector.

12. The method of claim 9, wherein said tube connection system comprises one or more light sources and one or more optical detectors.

13. The method of claim 9, wherein said one or more optical detectors comprises a red, green, and blue (RGB) detector.

14. The method of claim 9, wherein said at least two spectrally distinct reflective regions comprise at least one geometrical shape.

15. The method of claim 9, wherein the at least two spectrally distinct reflective regions exhibit at least one concave region and at least one convex region.

16. The method of claim 9, wherein the at least two spectrally distinct reflective regions cover a substantial portion of said tube connector.
