1. A tube connector for connecting between a fluid sampling tube and a device connector of a fluid analyzer, the tube connector comprising:
- a circular annular end face adapted to facilitate identification of the tube connector, wherein said circular annular end face comprises at least two spectrally distinct reflective regions adapted to reflect light at different wavelengths when said circular annular end face is revolved relative to said device connector, said at least two spectrally distinct reflective regions arranged such that a verification system of said fluid analyzer determines an operation mode of the fluid analyzer by identifying recurring changes of reflectivity of the reflective regions during the revolving of said tube connector relative to said device connector.

19. A fluid analyzing device, said device comprising:
- a device connector adapted to receive a tube connector; and
an RGB detector adapted to receive light of at least two colors reflected from at least two corresponding spectrally distinct regions of a circular annular end face of said tube connector during revolving of the end face relative to the device connector and to produce a signal indicative of the light received; and
a processor adapted to identify a type of the tube connector based on said signal received from said RGB detector; and
wherein the processor determines an operation mode of said fluid analyzer according to the tube connector type identified;
wherein the identification of the tube connector type by said processor comprises identification of recurring changes during the revolving of said tube connector relative to said device connector.
- a device connector adapted to receive a tube connector; and

20. A method for identifying a tube connector type attached to a fluid analyzer, the method comprising:
- transmitting light toward a circular annular end face of the tube connector;
detecting light reflected from at least two spectrally distinct reflective regions on the circular annular end face of the tube connector during revolving of the end face relative to the device connector of the fluid analyzer;
producing a signal indicative of the reflected light;
identifying the type of the tube connector based on the signal produced; and
determining an operation mode of the fluid analyzer according to the connector type identified;
wherein identifying the type of the tube connector comprises identifying recurring changes during revolving of the tube connector relative to the device connector of the fluid analyzer. - View Dependent Claims (21)
