Patent ID: 7998432

Claim:
An analytical device for in vitro diagnosis, comprising: a model of reaction unit cuvettes for different types of tests, using different measurement technologies, a vertical-axis rotor which is associated with rotation drive means and provided with a horizontal toothed crown wheel, delimiting radially outwardly open cavities for receiving the unit cuvettes, a device for supplying the toothed crown wheel with the unit cuvettes, a device for supplying the cuvettes with specimens of biological liquid to be analyzed, stations arranged around the toothed crown wheel, for carrying out measurements and/or analyses, at least one of the stations comprising means for unloading/loading the cuvettes for carrying out a measurement and/or an analysis at the station, outside the toothed crown wheel, an automaton controlled by on-board software for managing sequences of a desired process for each unit cuvette, and means for maintaining a temperature of the unit cuvettes at a given level comprising an upwardly open U-shaped stationary toroidal piece delimiting, with the toothed crown wheel, a temperature-regulated space in which the cuvettes are displaced under the action of the toothed crown wheel, the U-shaped toroidal piece comprising an outer wall having a radial opening proximate to each station, where the unit cuvette is introduced or withdrawn, wherein the U-shaped toroidal piece is arranged under the horizontal toothed crown wheel.
