Compact analyzer for dry biochemical analysis of blood samples

Compact analyzer for dry biochemical analysis of blood samples, integrating onto a common chassis (11):

• a measuring chamber (20) adapted to receive a disposable rotor (13) including at least one diluted sample receiving central chamber (13′) and, around that central chamber, a plurality of microtanks (13A, 13B) containing dry reagents and adapted to receive fluid from that central chamber during centrifuging of this rotor,
• a digital dilution module (21) of fixed or variable ratio defined as a function of the species of the sample to be analyzed and adapted to dispose a diluted sample into a central chamber of this rotor from a blood sample (22) from a given species,
• a sample centrifuging module (12) adapted, inside the measuring chamber, to centrifuge the rotor and position it angularly at a plurality of angular positions,
• an optical module adapted to apply beams of light to the interior of the measuring chamber, in areas that may be occupied by microtanks of the rotor, in at least some of said angular positions of the rotor, this optical module including a flash-lamp type light source (14) and a reference light sensor (16),
• an electronic processing and control system (23, 24, 25) for controlling the dilution module, the optical module and the centrifuging module, to acquire measurements from the beams intercepted by said areas of the measuring chamber, to process these measurements and to deduce results therefrom, said processing system including an external memory reader (26) adapted to read a portable external memory (27) containing at least information characteristic of at least the disposable rotor in use.
