Tube verifier

摘要

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.

主权项

1. A tube connector, comprising:
a circular annular end face configured to be inserted into a tube connection system and illuminated by the tube connection system, at least a portion of the circular annular end face comprising at least a first spectrally distinct reflective region, at least a second spectrally distinct reflective region and at least a third spectrally distinct reflective region, said first and second spectrally distinct reflective regions positioned at different regions of said circular annular end face, said first spectrally distinct reflective region configured to reflect light at a first wavelength when illuminated by the tube connection system, said second spectrally distinct reflective region configured to reflect light at a second wavelength when illuminated by the tube connection system, the first wavelength being different from the second wavelength, said third spectrally distinct reflective region configured to reflect light at a third wavelength when illuminated by the tube connection system, the third wavelength being different from both the first and second wavelengths, and wherein tube connector is configured to provide encoded data controlling operation of the tube connector system, via the three spectrally distinct reflective regions, when the tube connector is inserted into and the encoded data read by the tube connection system.
